LPE2501 ACADEMIC WRITING LECTURE NOTES 1 [WEEK 1 – 5] Topics: 1. Introduction to Academic Writing 2. Features of Academic Writing 3. Language in Academic Writing 4. Pre-writing Strategies 5. Components of an Academic Essay 6. Structure of a Paragraph 1. INTRODUCTION TO ACADEMIC WRITING Academic writing refers to the style of writing that follows a specific structure and uses formal academic language. It involves stating writers’ viewpoints objectively and supporting them using credible evidence and references. Academic writing demonstrates elements of unity, coherence and adheres to the formal conventions of punctuation, spelling, grammar, citation and referencing style. Read the two examples of texts below: Example of an Academic Text Over the past decade, an increasing number of epidemiological studies have linked urban air pollution to increased risk for morbidity and mortality. These new findings have led to revised air pollution standards for the United States, and it will probably have similar consequences in other countries around the world. This new evidence on adverse health effects of air pollution has also motivated research to identify those groups within the population who may be at increased risk from exposure to air pollution, for example, infants, persons with chronic heart and lung disease, and the elderly population. Example of a Non-academic Text Many people are getting sick and dying because of air pollution. So, the law for air pollution in the United States has changed. Other countries may also change their air pollution law. The group of people who are in danger because of air pollution are babies, people with serious heart and lung problems, and old people. 1. Which of the examples above contain lengthy sentences? 2. Which of the examples above use simple everyday words? 3. Which of the examples above is most likely found in academic journals? 1 2. FEATURES OF ACADEMIC WRITING Features Organisation Descriptions Formal structure Introduction - includes thesis statement Body - consists of paragraphs with topic sentences and supporting sentences and details Conclusion – has a concluding sentence or paragraph Language Complex and uses a variety of sentence types – simple, compound, complex, compound-complex sentences Language is more formal - no usage of colloquial words and expressions (e.g. boring and stuff), contraction (e.g. isn’t and doesn’t), phrasal verbs (e.g. go out and show off), personal pronoun (e.g. I, we, you, us) Cohesion across sentences (e.g. use of transition signals to show relationship between ideas) Addresses specific readers Has objective that is specific and not personal Contains precise facts and figures Incorporates ideas taken from various sources with proper in-text citation and referencing Text Text types – informative, argumentative, comparison and contrast, cause and effect Examples Academic books Research papers or research articles Dissertations or thesis Literary analysis Academic journals Lab reports Essays Content 2 3. LANGUAGE IN ACADEMIC WRITING The writing process involves editing and revising your work for grammatical errors, mechanics of writing (punctuation, capitalisation and spelling) and sentence structure. Below are some guidelines to help you edit and revise your writing tasks. You will learn about language and sentence errors in detail in Lecture Notes 6 and 7. Subject-verb Agreement (SVA) Subjects and verbs must agree in number If the subject is singular, the verb must be singular too. Example: The doctoral student writes every day. If the subject is plural, the verb must also be plural. Example: The doctoral students write every day. Verb tenses Three common tenses used in academic writing are: Simple present tense – Use to describe a general truth or a habitual action. This tense indicates that the statement is generally true in the past, present, and future. Example: The hospital admits patients whether or not they have proof of insurance. Simple past tense – Use the simple past tense to describe a completed action that took place at a specific point in the past. Example: Zimbardo (2018) researched many aspects of social psychology. 3 Present perfect tense – Use the present perfect to indicate an action that occurred at a non-specific time in the past. This action has relevance/effect in the present. Example: Numerous researchers have used this method. Spelling and Vocabulary Use academic vocabulary or formal words when writing academic piece. If you are not sure of certain words and their spelling, use a dictionary to help you. Avoid having spelling errors as they may cause confusion to your readers. Note: British spelling should be used in all writing tasks for LPE2501 Academic Writing course. Punctuation Use correct punctuation to convey your ideas accurately. You may refer to the following links to help you with punctuation. https://student.unsw.edu.au/punctuation-guide https://libguides.reading.ac.uk/writing/punctuation EXERCISE 1 Read the following sentences. Identify any language, spelling or punctuation error and rewrite the sentences correctly. 1. Urbanisation has causing many problems to the environment and to the human population. ________________________________________________________________ ________________________________________________________________ 4 2. Urbanization allows people to move to cities and towns because they view rural areas as places with hardship and primitive lifestyle ________________________________________________________________ ________________________________________________________________ 3. Air pollution often plague industrialised cities, particularly during their early development. ________________________________________________________________ ________________________________________________________________ 4. In the year 1800 only about 2 percent of the world's population live in urban areas. (Johnson & Hague, 2019) ________________________________________________________________ ________________________________________________________________ 5. According to The Department of Economic and Social Affairs, two-thirds of the world's people is expected to live in urban areas by the year 2050. ________________________________________________________________ ________________________________________________________________ Academic Vocabulary Academic writing requires the use of formal, objective and impersonal words. This ensures that ideas and arguments are written in a clear, convincing and professional manner. Formal words Vs. Informal words Example: Informal words Formal words A couple of researchers have found out that sleep affects mental alertness. Several researchers have discovered that sleep affects mental alertness. The students did the experiment in the lab. The students conducted the experiment in the lab. 5 Apart from using formal words, the following features of informal language should also be avoided for academic writing. Features of informal language Definition Example Appropriate alternative Contractions Shortened words, with missing letters from the original word The authors didn’t provide evidence for their claim. The authors did not provide evidence for their claim. We administered the questionnaire to the participants. The questionnaire was administered to the participants. Cosmetic companies are spending big bucks to advertise their products. Cosmetic companies are spending a large amount of money to advertise their products. Safety officers are looking into the problem. Safety officers are investigating the problem. Meteorologists have issued a storm warning since it has been raining cats and dogs. Meteorologists have issued a storm warning since it has been raining heavily. Personal pronoun Substitute for the proper name of a person or thing E.g. I, we, us, you, your Colloquial / slang words Words and expressions that are used in everyday spoken language E.g. stuff, gig, chap Phrasal verbs Combination of words that usually take on a different meaning of the original verb E.g. verb+prep or verb+adv Idiomatic expressions Words that have a different meaning from the meaning of the words in the expression 6 EXERCISE 2 Identify suitable formal words to replace the informal words/expressions listed below. Informal words / expressions 1 Enough 2 Start 3 Get 4 Chance 5 Come across 6 Going up 7 Cut out 8 Beyond a shadow of doubt 9 Cut to the chase 10 Check it out Formal words EXERCISE 3 Improve the language in the text below by replacing the informal words or expressions with formal words. Workplace stress is one of the most formidable obstacles to employees in the workplace. Stress at the workplace doesn’t only affect the productivity of employees but also impacts their physical and mental health. Developing effective strategies for managing stress in the workplace is a good step in protecting the physical and mental health of employees and ensuring continued productivity. Firstly, employees need to identify the symptoms of stress they might be facing in order to look out for possible solutions (World Health Organization, 2018). The symptoms of stress fall into two categories, physical and non-physical symptoms. Physical symptoms are often the harder of the two to identify as they can be easily dismissed as the symptoms of other sickness. Physical symptoms include chest pain, 7 overtiredness, and changes to sleep patterns, while non-physical symptoms include feeling overwhelmed, feeling sick and tired, and worried. Apart from that, employers play a very big role in minimising workplace stress. Employers need to set reasonable workload for their employees. So much workload that is unachievable will leave employees feeling stressed and overwhelmed. In addition to setting reasonable workload, work completion targets should be at levels that are achievable with clear instructions. Out of the blue and unclear work assignments often lead to confusion and stress among employees. Therefore, employers must set clear guidelines for work assignments to be done satisfactorily.

Clustering is used in the process of brainstorming to help writers to identify the focus of the topic. It allows the writers to explore ideas in a visual form. In deciding the writing topic and focus, you can brainstorm and narrow down ideas that interest you using the clustering technique. Steps 1 - Draw a box in the centre of the paper and write the topic. 2 - Write ideas in the boxes around the box in the centre. 3 - Think about each of the ideas, draw boxes around them, and write more ideas. E.g. Exercise Harmful effects Types Benefits - sore muscles -aerobic exercise - mood - insomnia - strength exercise - weight loss - depression - flexibility exercise - energy levels 9 Outlining is a technique that helps writers to arrange ideas in an organised and logical manner. It also helps the writers to stay focussed. After you have brainstormed for a topic and focus, you should outline your points. Steps 1 - List down points relevant to the topic and main ideas. 2 - Arrange your ideas in a logical order. 3 - Write an outline. E.g. Topic: Benefits of Exercise Paragraph 1 Main idea : Exercise alleviates mood Point 1 : releases endorphins Point 2 : reduces stress Paragraph 2 Main idea : Exercise helps in weight loss Point 1 : burns extra calories Point 2 : helps reach ideal weight 10 EXERCISE 4 Choose a topic from the given list and brainstorm for possible ideas using the clustering technique. Student volunteering Travel Stress Artificial intelligence Fast food Climate change 11 EXERCISE 5 Based on the topic chosen in Exercise 1, write an outline using the outlining technique. Topic: ____________________________________________________________ Paragraph 1 Main idea : Point 1 : Point 2 : Paragraph 2 Main idea : Point 1 : Point 2 : 12 5. COMPONENTS OF AN ACADEMIC ESSAY An academic essay consists of three major components, which are introductory paragraph, body paragraphs, and concluding paragraph. The chart below shows the organisation and components of an academic essay. ESSAY I. Introductory paragraph General statements Thesis statement II. Body paragraphs Paragraph 1 A. Topic sentence 1.

Concluding paragraph Restatement or summary of the main points; final comment 13 Sample of an Academic Text Read the following academic text. As you read it, notice the different parts of an academic text. In recent years, many people have become increasingly aware of the need for optimum health. Almost everywhere people turn, whether it is to a newsstand, television or billboard, information for guarding and improving health bombards them. Although much of this information is commercially motivated by those eager to sell vitamins and health supplements, some of the information especially on regular exercise, merits serious attention. Numerous studies have proven that regular exercise provides many benefits, and it only needs to be carried out at least three times a week for thirty minutes. Regular exercise releases tension, improves appearance, and increases stamina. The first benefit of regular exercise is the release of tension. Tension builds in the body because of an over-accumulation of adrenaline produced by stress, anxiety or fear. Health experts agree that performing calisthenics or participating in an active sport such as tennis or volleyball for thirty minutes releases tension. If people swim, jog or ride a bicycle for thirty minutes, they should sleep better at night and have a better temperament the next day. In addition, after the release of tension, petty irritations and frustrations should be less troubling. For example, Roscoe (2010) explains that an employee stressed with work and traffic congestion, may rush home, argue with the family, and eat excessively. Taking about thirty minutes to release frustrations through physical exercise could help him or her avoid this behaviour. Therefore, exercising regularly can eliminate or at least control tension. Another benefit of regular exercise is improved appearance. Exercise takes perhaps a month or longer to show its results in a trimmer and firmer figure. For instance, research shows that people who are overweight, may be able to burn away most excess fat and tighten muscles, thereby reshaping the physique through regular exercise (Centre of Public Health California, 2013). Having improved muscle tone and even posture, people will wear clothes more attractively and comfortably. Combined with a well-balanced diet, regular exercise will also improve skin condition. This improved appearance will provide confidence and favourably impress others. Thus, regular exercise is beneficial as it will help towards the betterment of one’s overall appearance. 14 In addition to the self-confidence engendered by an improved appearance, regular exercise also increases stamina. Regular exercise allows for a stronger and healthier body and is obviously more capable of working harder and withstand fatigue. Paisley (2012) states that “a worker who exercises should be able to complete a forty-hour week at work and still retain enough energy for mowing the grass, painting the garage or cleaning the windows at home” (p. 87). Similarly, a student who exercises regularly would be able to attend classes and still find the energy and stamina to work part-time and accomplish various tasks efficiently. Hence, improved endurance is one of the benefits of regular exercise. In conclusion, people can benefit immensely by exercising regularly. Although easy solutions to the goals of losing weight and achieving an attractive and energetic body saturate the media, acquiring these benefits is not easy. However, the rewards are fully worth the effort of regular exercise, which makes people feel relaxed, look healthy and have adequate strength for strenuous as well as routine activities. 15 COMPONENT 1: INTRODUCTORY PARAGRAPH An introductory paragraph introduces the topic of the academic text to the reader. It also provides an overview of the content of the text. It consists of two parts which are general statements and a thesis statement. GENERAL STATEMENTS General statements provide background information of the topic to the reader. It also attracts readers’ attention to the topic of the text. Read the introductory paragraph below from the previous text: 1. Based on the general statements, what do you think is the topic of this text? 2. What information can you find in the general statements? In recent years, many people have become increasingly aware of the need for optimum health. Almost everywhere people turn, whether it is to a newsstand, television or billboard, information for guarding and improving health bombards them. Although much of this information is commercially motivated by those eager to sell vitamins and health supplements, some of the information especially on regular exercise, merits serious attention. Numerous studies have proven that regular exercise provides many benefits, and it only needs to be carried out at least three times a week for thirty minutes. Regular exercise releases tension, improves appearance, and increases stamina. THESIS STATEMENT 16 GENERAL STATEMENTS THESIS STATEMENT A thesis statement states the main ideas that will be discussed in the body paragraphs. The body paragraphs are written with reference to the thesis statement in the introductory paragraph. A good thesis statement: focuses on a specific aspect of the topic may list subtopics of the main topic; sets the pattern for the paragraphs to follow by indicating the main points that will be developed in the body paragraphs often appears as the last sentence of the introductory paragraph Look at the examples of thesis statements below: Topic: Advantages of Reading among Adults Thesis statement 1: Reading brings many advantages to adults as it can improve concentration, reduce stress, and provide tranquillity. This is a well written thesis statement as it provides readers with all the main points that will be discussed in the body paragraphs. This style of writing a thesis statement will allow readers to have a clear idea of what to expect in the body paragraphs. Thesis statement 2: There are three advantages of reading for adults. This thesis statement states the number of advantages that will be discussed but does not indicate the main points. It is an acceptable style of writing a thesis statement in academic writing. Thesis statement 3: Reading is a popular hobby nowadays. This thesis statement is too general. It does not provide the specific aspect of the topic (reading) or the main points that will be discussed in the body paragraphs. You should avoid writing a thesis statement that is too general. 17 COMPONENT 2: BODY PARAGRAPHS A paragraph in the body of an academic text contains the discussion of the main points mentioned in the thesis statement. This is where the topic is developed using facts, examples and other details. A body paragraph consists of a clear topic sentence with reference to the thesis statement, relevant supporting points and supporting details, and also a concluding sentence. Below is the structure of a body paragraph: TOPIC SENTENCE - states the topic and controlling idea of the paragraph facr SUPPORTING SENTENCES BODY PARAGRAPH - provide explanation, examples and details of the topic - consists of three parts CONCLUDING SENTENCE - summarises the main points of the paragraph or restates the topic sentence in different words 18 Below is an example of an academic paragraph and its components. Transition signals to show the connection between ideas TOPIC The first benefit of regular exercise is the release of tension. Tension builds in the body because of an over-accumulation of adrenaline produced by stress, anxiety or fear. Health experts agree that performing calisthenics or participating in an active sport such as tennis or volleyball for thirty minutes releases tension. If people swim, jog or ride a bicycle for thirty minutes, they should sleep better at night and have a better temperament the next day. In addition, after the release of tension, petty irritations and frustrations should be less troubling. For example, Roscoe (2010) explains that an employee stressed with work and traffic congestion, may rush home, argue with the family, and eat excessively. Taking about thirty minutes to release frustrations through physical exercise could help him or her avoid this behaviour. Therefore, exercising regularly can eliminate or at least control tension. CONCLUDING SENTENCE 19 Paraphrase/ summary (supporting detail): In-text citation: Ideas from a credible source expressed in your own words Author’s surname and year of publication SENTENCE SUPPORTING SENTENCES Reporting verb used to introduce borrowed information 6. STRUCTURE OF A PARAGRAPH TOPIC SENTENCE A topic sentence indicates the main idea of a paragraph. It provides an introduction and focus for each paragraph. A good topic sentence: must be a complete sentence; not fragment has a clear topic and controlling idea usually appears in the first sentence of the paragraph begins with transition signals such as first, second, finally uses keywords or phrases from the thesis statement to indicate the part of the thesis that will be discussed Example 1 a) Firstly, social media can negatively affect face-to-face communication. TOPIC CONTROLLING IDEA b) Next, social media can also cause mental distress among its users. TOPIC CONTROLLING IDEA Example 2 c) Understanding tourists’ behaviour is one of the ways to promote tourism. CONTROLLING IDEA TOPIC d) Researching tourists’ demand is another way to market a tourist destination. TOPIC CONTROLLING IDEA TOPIC T TOTHDHDFNBFDNDFBBBD TOPIC PICTTYYY OPIC 20 Example 3 Writing Topic Sentences with reference to the Thesis Statement Thesis Statement: Overscheduled lifestyles, changes in family structure and emphasis on individualism are three reasons for the generation gap between younger and older people. Explanation: This thesis statement tells us that the topic of the text is the gap between younger and older people and the focus is the causes of this gap. We also know that the first paragraph of the text will discuss how overscheduled lifestyles affect the generation gap between younger and older people. The second paragraph will discuss the changes in family structure and how it affects family relationships, while the third paragraph will discuss how individualism can create a difference between generations. To establish the connection between the thesis statement and the paragraphs of the text, the following topic sentences are used. Topic Sentence 1: Overscheduled lifestyles is one reason why younger and older people become isolated from each other. Topic Sentence 2: Another reason for the generation gap between younger and older people is the change in family structure from extended families to nuclear families. Topic Sentence 3: The third cause of the generation gap between younger and older people is emphasis on individualism. 21 EXERCISE 6 Read the thesis statements below. For each thesis statement, decide if it is a good thesis statement. If not, rewrite the thesis statement according to the qualities of a good thesis statement. Topic: The Benefits of Using Technology in the Classroom 1. These days technology is widely used in many fields. _________________________________________________________________ _________________________________________________________________ 2. The use of technology in the classroom has many benefits. _________________________________________________________________ _________________________________________________________________ 3. The usage of technology in the classroom improves knowledge retention, encourages individual learning, and enhances classroom engagement. _________________________________________________________________ _________________________________________________________________ 4. There are three benefits of using technology in the classroom. _________________________________________________________________ _________________________________________________________________ 5. Cool Math, Edmodo, and Fun Brain are some examples of the many education technology tools that can be used to enhance classroom learning. _________________________________________________________________ _________________________________________________________________ 22 EXERCISE 7 Read the thesis statement and topic sentences in each question. For each topic sentence, decide if it is a good topic sentence. If not, rewrite the topic sentence according to the qualities of a good topic sentence. 1. Thesis Statement: Exposure to violence, an inadequate rating system and too little parental supervision are three reasons why children should not play video games. Topic Sentence 1: Children in the United States love to play video games. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ Topic Sentence 2: Inadequate rating system for evaluating video games is another reason why children should avoid video games. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ Topic Sentence 3: Next, there is too little parental supervision. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ 23 2. Thesis Statement: Social media in today’s society allows people to stay connected, to keep abreast with the latest news and to communicate across borders. Topic Sentence 1: Social media allows people to stay connected. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ Topic Sentence 2: The second advantage is that people are able to keep abreast with the latest news around the world. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ Topic Sentence 3: Is a communication tool. Is the topic sentence appropriate? If not, what is the problem? _________________________________________________________________ _________________________________________________________________ 24 EXERCISE 8 Write an appropriate topic sentence for each of the paragraphs below. 1. ___________________________________________________________________ ___________________________________________________________________ Assistive technology can be used to increase, maintain or improve the capabilities of students with disabilities. For example, expert tutoring software presents instruction in small, sequential steps, at varying levels of difficulty, and students can use the software independently while working at their own pace. In addition, assistive technology also includes computer programmes and tablet applications that provide text-to-speech and speech-to-text application, word prediction capabilities and graphic organisers to assist in speech and language learning. Hence, advances in technology such as assistive technology provide disabled students with the opportunity to learn and develop new skills. 2. ___________________________________________________________________ ___________________________________________________________________ Students who study abroad stand a chance to get better jobs when they return to their home country. This is because their qualifications and experiences may allow them to get jobs that are higher paid, and they have a better chance of getting a promotion quickly. Another advantage of studying abroad is the independence students’ gain from being in a foreign country. For example, students have to cope with the challenges of living alone and meeting new people from different cultures. This will enable them to become more confident in their lives and relationships with others. Thus, studying abroad is a very rewarding and beneficial experience for students. 3. ___________________________________________________________________ ___________________________________________________________________ After-school programmes such as sports and games, art and music activities, internships in local area businesses and professional organisations as well as volunteer activities in the community would help engage teens in worthwhile pursuits outside of school hours. More job opportunities for teens, especially those funded by state and local programmes, would offer income for teens as well as work for the community. Outreach to families through schools, community organisations and places of worship would help promote inter-generational activities that could improve family ties, helping teens to work on their problems at the family level instead of taking them to the streets. Therefore, the problem of teen gang violence can be eliminated with the combined effort of the community via numerous programmes. 25 SUPPORTING SENTENCES AND SUPPORTING DETAILS Supporting Sentences Supporting sentences explain and develop the idea expressed in the topic sentence. These sentences must represent the writer’s point of view and voice. EXERCISE 9 Read the topic sentences below. Write three supporting sentences that could be included in the paragraph. 1. Topic Sentence: Participating in recreational activities brings many benefits to students. Supporting Sentence 1: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 2: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 3: ___________________________________________________________________ ___________________________________________________________________ 2. Topic Sentence: The main reason for unemployment among fresh graduates is the lack of communication skills. 26 Supporting Sentence 1: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 2: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 3: ___________________________________________________________________ ___________________________________________________________________ 3. Topic sentence: One of the ways to promote Green Living is through awareness campaigns. Supporting Sentence 1: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 2: ___________________________________________________________________ ___________________________________________________________________ Supporting Sentence 3: ___________________________________________________________________ ___________________________________________________________________ 27 Supporting Details There are several kinds of supporting details, such as examples, facts, statistics and quotations. These supporting details are usually taken from other sources i.e. journals, books and credible online sources. Supporting details further develop the supporting sentences. They also add to the validity of the main idea expressed in the topic sentence. This information, however, must be carefully documented using proper citation methods and referencing convention to avoid plagiarism. You will learn further about citation and referencing in Lecture Notes 2. EXERCISE 10 Read the paragraphs below. Underline the supporting details and decide whether they are examples, facts, statistics or quotations. 1. Wildlife tourism also has an implication on physiological changes in animals subject to disturbance. Since animals are a regular subject to wildlife watching activities, it gives an unpleasant impact to their behavioural responses. Getting too close to animals can result in adverse effects on wildlife, even if they are not apparent to the observer. Some animals may flee, others may be stressed and have physiological responses. For example, animals in the Northern Territory in high visitation areas have become accustomed to human presence, and visitors may enjoy passive interactions with these animals through wildlife watching and photography (Gross, 2012). This can cause prolonged stress in animals which may lead to a decrease in weight, reduction in breeding success and increased vulnerability to disease. Supporting detail type: ____________________ 2. For many working adults, online education has greatly enhanced the opportunity to take classes and complete their studies. Research indicates that although most online students successfully complete their degree programme, about forty percent of them fail in their studies (Bates, 2010). Most online students pursue their study online because they realise the many advantages of online education; nevertheless, it can be a major issue if students do not put in sufficient effort and time in completing their studies. In most cases, students can access their course at anytime from anywhere. This means that parents, working students and professionals on the move have the option of attending classes no matter how hectic their work schedule. Students only need a computer and Internet access to take online classes. Supporting detail type: ____________________ 28 3. All languages change over time and vary from place to place. "Language is subject to change and is not caused by unnecessary sloppiness, laziness or ignorance" (Aitchison, 1981, p.67). Languages may change as a result of social or political pressures such as invasion, colonisation and immigration. Language also changes very subtly whenever speakers come into contact with each other. No two individuals speak identically; people from different geographical places clearly speak differently, but even within the same small community there are variations according to a speaker’s age, gender, ethnicity as well as social and educational background. Through interactions with different speakers, new words, expressions and pronunciations are integrated into speech. Supporting detail type: ____________________ 4. One vital step in protecting the environment is by reducing the use of plastic bags. Plastic bags cost the city of San Francisco 17 cents each to handle once discarded. Over the state, California spends about 25 million dollars sending plastic bags to landfills each year, and another 8.5 million dollars to remove littered bags from streets. While a grocer pays next to nothing for plastic bags and gives them to customers at no charge, the follow-on cost to society is much higher. If customers can be trained to bring their own reusable bags every time they shop, this will lead to a reduction in one of the major polluting items in the environment. Paper bags are biodegradable and make a good option to reduce the use of plastic bags (Society for the Environment, 2013). Grocery stores and other retail stores should be actively discouraged from giving out plastic bags. There are numerous and various incentive systems employed in some cities around the world in reducing the use of plastic bags to conserve the environment. Supporting detail type: ____________________ 29 EXERCISE 11 Select the most suitable excerpts to be used as supporting details for the following topic sentences and supporting sentences. 1. Topic Sentence: Firstly, one of the primary cause of climate change is bad agronomic practices within the agricultural sector. Supporting Sentence: Nitrogen-based fertilizers that are commonly used in agronomic practices release Nitrous Oxide gas (N20) into the air. Supporting Details: A) Nitrogen is critical to plant growth and reproduction. The addition of nitrogen is crucial in sustaining soil fertility as pasture and crop growth will often respond to an increased availability of soil nitrogen (Agriculture Victoria, n.d.). B) Green (2020) claims that at present, human agricultural practices account for over two-thirds of global N20 emissions. Research has shown that excess nitrogen can lead to overgrowth of algae in water and in the atmosphere, N20 can also destroy the ozone layer protecting the earth from ultraviolet radiation. 2. Topic Sentence: Secondly, cloud accounting software ensures data security. Supporting Sentence: Data are stored properly in cloud and continuously backed up which in return will avoid data loss. Supporting Details: A) Dimitriu and Matei (2015) explain that the emergence of cloud accounting software has managed to ensure data security as financial data are automatically saved into the cloud. Users can schedule data to be stored and backed up accordingly, whether on a daily, weekly or monthly basis. Since data is backed up regularly in a cloud software, users are not exposed to data loss. B) Erkins (n.d.) claims that one of the greatest advantages of cloud accounting software is the ability to access data from the cloud easily. Users can access their data from anywhere and they could also collaborate with their business partners and employees at any time. 30 3. Topic Sentence: First, drinking water promotes healthy mental function which is important to live a healthy life. Supporting Sentence: Dehydration will lead to reduced mental and cognitive functions. Supporting Details: A) Dehydration must be treated by replenishing the fluid level in the body. This can be done by consuming clear fluids such as water, clear broths, frozen water or ice pops, or sports drinks. People who are dehydrated should avoid drinks containing caffeine such as coffee, tea and sodas (Cobb, 2017). B) Failing to drink enough water can cause headaches, shorter attention span and difficulty to concentrate. Research has also shown that being dehydrated by just 2% impairs performance in tasks that require attention, psychomotor and immediate memory skills (Adan, 2012). 4. Topic Sentence: Next, another benefit of recycling is it saves energy. Supporting Sentence: Turning recycling products into usable materials requires less energy in comparison to processing raw materials. Supporting Details: A) Manufacturing recycled paper uses only 60% of the energy needed to produce paper from fresh pulp. On top of that, manufacturing one ton of paper with recycled paper stock can save between 3,000 and 4,000 kilowatt-hours over the same ton of paper made with fresh pulp (U.S. Environmental Protection Agency, n.d.). B) Recycling reduces the cost of production during manufacturing. Using existing materials to produce new products is cheaper than mining and manufacturing new raw materials (Synoracki, 2019). 31 5. Topic Sentence: First, one of the effects of stress is it can compromise the immune system. Supporting Sentence: Stress has been clinically proven to interfere with inflammatory processes, wound healing and responses to infectious agents in the body. Supporting Details: A) High stress levels can raise blood pressure and heart rate. Over time, high blood pressure can cause serious health problems, such as stroke and heart attacks (U.S. Department of Health & Human Services, n.d.). B) According to the American Psychological Association (2004), stress will reduce the number of natural killer cells of lymphocytes in the body, which are needed to fight viruses. 32 CONCLUDING SENTENCE A concluding sentence is the last sentence of a paragraph. It either restates the main idea of the paragraph by repeating the topic sentence in different words or summarises the main points of the paragraph. A concluding sentence begins with suitable transition signals such as therefore, hence and thus. EXERCISE 12 Write a suitable concluding sentence for each of the following paragraphs. 1. The changes in roles of nurses through a university education have affected their practice and their image among the community. Previously they were seen as the doctor’s helper. “A good nurse was disciplined, sober, humble, obedient and never complained about her work” (Stevens, 2012, p.202). Currently, the roles of nurses as part of a team of health professionals have also expanded as a result of university education. For example, nurses are required to explore different facets of health and develop more specialised knowledge, giving them the ability to collaborate effectively (Duffy et al., 2011). They also have had a more influential role in diagnosis, treatment and prevention. This is due to the stronger theory base that is taught at universities. ___________________________________________________________________ ___________________________________________________________________ 2. People need to continuously adjust their habits to bring an end to climate change. Simple changes, like recycling and turning off the lights when leaving a room is a good place to start, but it cannot stop there. For example, when people are out shopping, they should carefully evaluate their purchases and buy fewer items. When people buy things they do not need, the things quickly end up in the landfill, which is a waste of resources. It is also important to look for ways to further reduce consumption at home. For example, paper towels could easily be replaced with cloth rags. People can also look for ways to minimise their use of other valuable resources by shifting their daily habits towards more sustainable practices such as taking shorter showers, eating less meat and walking to nearby locations rather than driving. ___________________________________________________________________ ___________________________________________________________________ 33 3. Choosing a college or university can be difficult for high school students. The most difficult part is finding a university that prepares them well for their future career. In order to get a good job, the curriculum that is taught must be thorough and upto-date. In addition, the educators must be highly qualified and respected in their fields. Another difficulty in choosing a university or college is affordability. Students need to be able to pay not only the tuition fees but also the living expenses. Fortunately, some institutions might be able to offer scholarships if students cannot afford the fees. Of course, a good location is also very important when choosing a college or university. The environment should be safe and quiet to facilitate studying. Moreover, there should be opportunities near the college or university for part-time jobs or internships to provide some work experience for students. ___________________________________________________________________ ___________________________________________________________________ 34
