1. (进入教材4。)

T: The text tells us some good and bad influences television has on us. Maybe there are many more influences besides the above. Now, let’s have a debate on the statement: Television has a bad influence on children.

(板书画线部分内容。)

Television has a bad influence on children.

T: Work in 2 groups. Group 1 agrees with the idea and you are the Affirmative Team. Group 2 disagrees with the idea and you are the Negative Team. There are some rules for you:

(1)Each team has three speakers. But both teams do research on the topic and try to find reasons for their point of view.

(2)The first speaker from each team presents their ideas.

(3)The second speaker further argues and disagrees with the previous speaker from the other team.

(4)The third speaker from each team disagrees with the other team’s ideas further.

(5)Speakers debate the statement freely.

(6)The third speaker makes a summary of what their team has argued.

Now, each group discusses and writes your ideas and reasons on a piece of paper and then

gives it to your speakers.

(教师告诉学生辩论程序和要领,也可写在小黑板上,学生分组讨论。)

T: Debate begins with the Affirmative Team, and then the Negative Team.

Example:

 
Affirmative Team
Negative Team
First speaker
We agree with the idea:
Television has a bad influence on children.
On the contrary, we disagree with the idea: Television has a bad influence on children.
Second speaker
We all know that there are many TV programs. But some are unhealthy. Children will act as what they see. Television also keeps us away from healthy outdoor activities.
We disagree with the idea because most of us can learn much from television. For example, it can increase our knowledge, help us collect information and make our life interesting and colorful.
Third speaker
While television makes our life interesting and colorful, we will also learn some rude words and bad behaviors, even accept some unhealthy ideas. For example, when a child sees a character who likes smoking, he will learn to smoke.
Good habits are formed gradually while bad behaviors are acted at once. In a word, television can’t have no bad influence on children.
I disagree with you. There are many healthy programs, and we can reject the unhealthy ones. At the same time, our parents sometimes give us some advice when we watch TV together.
Obviously, television has more good influences on our life. There are many healthy programs and we can learn a lot. So we can’t say television has bad influence on children.
