四、习作修改（做短文改错，背经典范文）

Dear editor，

Im a senior high school student in Nanchang，named Li Hua. Now many students have iPads and think its a fashion to use it. Use an iPad，we can listen to music，download a lot of learning materials and read them on the screen. Apparent，it is helpful to our study，especially to our English listening.

Some students，however，bring their iPads to classrooms and listen music with earphones，that makes the teacher and other students greatly annoying. Whats worse，some of them even waste precious times in class playing video games.

In my opinion，as students，we should made good use of iPads. The classroom is a place for students to study from，and therefore，concentration is badly needed for us to learn our lessons. Furthermore，the school should make a rule to guide the students to use iPads at a proper way.

Yours sincerely，

Li Hua

参考答案与范文

四、习作修改

作者介绍了使用iPad的优缺点，并发表了自己的看法。

1. it→them 指代不一致，此处指代前面提到的iPads，应为复数形式。

7. times→time 此处指时间，为不可数名词，没有复数形式。

8. made→ make 情态动词后加动词原形。

五、课堂练习

Dear Headmaster，

We have been asked about our opinions on opening iPad classrooms. I am in favor of this plan for the following reasons. To begin with，everyone learns differently. Students can customize their iPad with materials that fit their level and learning style，and thus tailor it to different needs. Moreover，When the iPad was connected to the Internet，students can interact with teachers and classmates about what they learn more conveniently. For the sake of environmental protection，opening iPad classrooms is a good way to save trees that we have been cutting down for paper. Most importantly，I believe students will develop their interests in the subjects by enjoying a new way of learning.

I hope you would take my ideas into consideration and we look forward to attending an iPad class.

Yours sincerely，

Li Hua

六、 课外作业

Dear Li Lei，

With the development of information technology，it is easy to find English movies. Many students use them as a way of learning English. By watching English movies，we can learn more about the world and life as movies present much richer contents than textbooks. In addition，we can hear English in real contest.

However，there are disadvantages. Some watch English movies with the Chinese subtitles，and dont pay attention to the English language or culture，making it complete entertainment rather than English learning.

In my opinion，watching English movies can be a fun and useful way of learning English，but only when it is done with careful planning and strict requirements.

I hope you will make progress in your English learning！
