2．表明自己的看法并提出建议；
3．词数在80左右。
提示词:
do a survey about…(做一个有关……的调查)
3% of the students (百分之三的学生)
参考范文：
A survey about smokers in a middle school tells that although 90% of all students never smoke, 3% of them often smoke and 7% sometimes do. In other words, 10% of the students smoke. That’s terrible.
As we know, smoking is harmful to our health. Every year, thousands of people lose their lives because of it. Smoking not only does harm to your health, but also wastes money. Because, a fire may be caused by cigarette ends. It’s a pity to learn that one ends in death by smoking.
In all, smoking is so dangerous that we should keep away from it.
