Ⅳ. One possible version:
A survey shows that many students have become shortsighted at a very young age. At present, about 70% of the students are shortsighted. Here are some main causes. Some students may not have enough sleep. And some spend much time reading or doing their homework without a rest. Others even watch TV or use computers for a long time.
In order to have good eyesight, we should do eye exercises every day. We can try to do more sports in our spare time. We also should have the good habit of using our eyes.
I think all of us should try our best to protect our eyes.

Find Your Own Way to Learn English
There are many ways to learn English, but everyone has his or her own way.
At first, I had many difficulties in l earning English. For example, I couldn’t spell some English words, and couldn’t understand what people said when they talk ed fast.
Now I have found some ways to improve my English. I copy down the new words for each unit and keep them in my mind. I listen to English tapes every day. And I also borrow English books and read them after class.
I think the most important thing to learn English well is to keep your mind on it so that you can improve your English.。
