It summarizes the information that the reader will come across in the rest of the paragraph. Generally speaking, the topic sentence is usually the opening sentence, but this is not always the case. Because of this, topic sentences must express the main content of the paragraph in a clear and concise manner. The sentences that follow will give us more information about the topic sentence. For example, if the topic sentence is about a movie that the writer has seen, the rest of the paragraph will expand on this. In a piece of formal writing, e.g. an essay, report, etc. we need to include a topic sentence in each major paragraph to guide the reader and keep him/her focused, and also to give the writing a good flow. Will and won’t to speculate about the future We use will and won’t to make speculations about the future to say what we think is going to happen. I think there will be more extreme weather conditions in the future. There won’t be any fossil fuels left in 50 years time. We can also add be with will and won’t when making speculations. There will be a shortage of food in overpopulated parts of the world. There won’t be enough food in overpopulated parts of the world. © Young Digital Planet 2015 – Core Curriculum for English – Teacher’s Guide Procedure Lead-in Key: Ask students to label the pictures.
