First, introduce passion, introduce topics
Teacher: Next, the teacher will do a survey: If anyone smokes or drinks at home, please raise your hand. It seems not uncommon to smoke and drink. Is smoking and drinking harmful? Today's class will bring clear answers to the students.
Second, analysis and investigation, clear debate.
Teacher: Which side do you agree with? Those in favor please sit in the first and second groups, and those against please sit in the third and fourth groups.
Post a debate card for the pros and cons. Students make choices and quickly adjust their seats. )
Teacher: OK, our point of view is very clear. Let's pay attention to the rules of debate (big screen presentation: respect each other's opinions and pay attention to listening). Please discuss in groups and prepare for the debate.
Third, debate and realize the harm.
Teacher: Both sides have expressed their opinions just now. Proponents insist that smoking and drinking are cool because they are full of coolness, leisure and relaxation, and enhance friendship. On the other hand, students who are against it think that smoking and drinking have many disadvantages, on the grounds that smoking and drinking are harmful to health and will cause accidents and crimes.

(The big screen shows that smoking and drinking are harmful: 1. Smoking and drinking affect your health. 2. Smoking and drinking reduce people's immunity. 3. Smoking and drinking lead to retrogression in study. 4. Smoking and drinking cause accidents and induce illegal crimes. )
(Large screen display: 1. Twenty or thirty kinds of harmful substances are released when a cigarette burns, which not only harms people, but also harms themselves. Smoking is equivalent to chronic suicide. 2. Alcohol can easily damage the nervous system, brain cells and directly endanger health. )
