【设计意图：随着手机的普及，越来越多的学生也拥有了自己的手机，教师引导学生谈论使用手机的优点和缺点，既为本节课要完成的辩论做铺垫，也锻炼了学生的英语口语表达能力。】
Step 2 Planning
As a class, Ss are required to think about the disadvantages and advantages of bringing mobile phones to school. Make a list of what Ss say. Then T makes a summary.
Advantages Disadvantages
We can use our mobile phone to pay for almost everything at the school shop. We can contact our family and friends at any time, especially in emergencies, such as being sick and being late to return home. They can help us consult learning materials more conveniently and faster when we have difficulties in studies. We can listen to the music to get relaxed during the break. ... Mobile phones can break down interpersonal relationships with classmates and teachers. We put much time and energy on conversations through QQ, WeChat or other social networking applications rather than face to face talk. 2. Using mobile phones too much is bad for our physical health. For example, looking at the screen for hours, our eyes will be dry. Bending over our phone can cause pain in the back and the shoulder. 3. Mobile phones can become a distraction in students’ lessons. New messages will surely distract students’ focus on what the teacher is saying in front of the class. 4. Mobile phones can help students cheat in the exam easily. 5. ...
2. Each student chooses one aspect to research. Then divide the whole class into two groups. In groups, Ss discuss how to divide the following tasks among themselves. Write the name of the group member beside the tasks.
Lead speaker (Introduce the topic and put forward arguments): ___________________________
Second speaker (Argue against the previous opposition speakers and introduce new arguments): ____________________________________
Third speaker (Argue against previous opposition speakers and build on key arguments): ____________________________________
Summary speaker (Summarize key arguments and conclude the debate): ____________________
【设计意图：通过头脑风暴式的讨论尽可能多地罗列带手机来学校的优缺点，为接下来的辩论赛提供素材；小组成员填写任务分配表，激发潜能，分工合作，培养团队精神。】
Step 3 Preparing
1. T asks Ss to prepare for the debate according to the following procedures:
Discuss the information with your group members.
Make a list of the points that your group comes up with.
Make a list of the points that you think the opposite members will think of.
Decide how to argue against those points.
2. T gives Ss an example to help them.
The “for” side:

Second speaker: I think students should be allowed to bring mobile phones to school. There are many examples for this/for ... For instance, ...

The “against” side:

Second speaker: The first opposition speaker has told us ...; on the contrary ...

Summary speaker: In a word, our group believes that students should not be allowed to bring mobile phones to school. It does great harm to us.
