Vincent(Introduction):Hello,everyone.Our group name is ACE.Our group members are Vincent,Yvonne,Giraffe,Lizzy,Bella and Pocaco.Our group leader is Giraffe.In this test,Vincent is in charge of the introduction,then Yvonne,Giraffe,Lizzy and Bella are responsible for the content,Pocaco finally is responsible for summing up.In our view,smoking should be banned in all public places in China.As we all know,there are many people smoking,although everyone knows smoking is harmful to us.Smoking and passive smoking is risk factor that leads to various diseases.Nowadays smoking is a common phenomenon in society.Smoking brings bad influence to oneself ,others,safety and teenagers.Next,my partners will elaborate on these points. Yvonne(Content1):To begin with,we think smoking is harm to ourselves. As the saying goes,the body is the capital of revolution. If people are addicted to smoking,it can cause a lot of diseases,such as cancer and many other diseases,it will reduce the length of our lives. And there are many stars die of cancer caused by too much smoking,such as denglijun and zhaolirong. Smoking for a long timecanmake our teeth yellow,too.Itis ugly.Thenaccording to MOH,approximately one million deaths every year in China are caused by tobacco----around one in six of all such deaths worldwide. In other words,someone in China dies approximately every 30 seconds because of tobacco use,or around 3000 people every day. This statistic is very alarming and it deserves our attention. Meanwhile,smoking is a waste of money,the longer we smoke,the more we addicted to it,it will cost a lot and it's a very large burden to the family,perhaps it will lead to family conflicts.So we think smoking should be banned in public place in China. Giraffe(Content2):Smoking is not only harmful to one's own body,but also harmful to others.When people smoke in public,people around them are forced to inhale secondhand smoke.Many people smoke in public and never consider others.Studies have shown that secondhand smoke increases the risk of coronary heart disease and increases the risk of death from coronary heart disease.Besides,according to <The 2010 global adult tobacco survey report of China>,China has 740 million people suffering from the danger of secondhand smoke,including 180 million children under the age of 15,each year more than 100,000 people died from secondhand smoke.In march 2004,Ireland became the first country in the world to legislate for smoke-free workplaces.This effectively reduces the harm of secondhand smoke to people.In the long term,to protect more people from secondhand smoke,smokers have better avoid smoking in public. Lizzy(Content3):To begin with,a cigarette usually takes about ten minutes to b urn,even butt can burn about 1-4 minutes.The center temperature of the butt i s 2 to 5 times the burning temperature of the general object.It is easy to cause fire if discarded butts are close to inflammable materials.According to <China Fire Yearbook >,between 2001 and 2005 the number of fires caused by smoki ng accounts for 7.7% of total fires. Besides,There are more than 3800 chemicals in the smoke from tobacco burning and majority is harmful to the people such as carbon monoxide nicotin e.According to the monitoring data of PM2.5 concentration in public places, th e average concentration of PM2.5 in a completely non-smoking area is 33.3 m icrograms per cubic meter. In contrast, the average concentration of PM2.5 in the smoking area was 103.95 micrograms per cubic meter, more than three ti mes the concentration of PM2.5 in a completely non-smoking area. Further more,smoking in public places is a reflection of lack of cultivation a nd morality.While smoking in public places is a bad habits for a small number of people,it affects the civilized image of the whole group. Bella(Content4):Smoking in public can have a bad effect on young people. *causes respiratory symptoms and diseases *affects normal growth and development *makes them feel that smoking is very popular and will blind them to imitation Teenagers have less immunity and lower self-control than adults * physically * psychologically * waste money Herd mentality and insufficient awareness make it easier for teenagers to be affected by smoking in public places. (Dr. Michael siegel, a researcher at Boston university's school of public health said that if teenagers rarely see smokers in growing environment,they may think smoking is not an accepted behavior by social , but if they often see someone smoking around them, they would think that smoking is normal.) Teenagers have a strong curiosity and many teenagers who know smoking is harmful to them but still smoke are driven by curiosity.Many Many people who smoke in public don't value their own behavior and unintentionally and thoughtlessly show the thought that "adult can smoke".So many teenagers are driven by this kind of psychology, using smoking as a sign of maturity, and begin to imitate adult smoking.Smoking in public can lead to a mistaken understanding of teenagers which makes them feel that smoking is very popular and will blind them to imitation. Pocaco(Conclusion):In conclusion,smoking should be banned in all public places in china.
