Answer 1

Take Good Care of Eyes
In recent years more and more school students have become near-sighted. It is reported that as high as 30 to 50 percent of the students wear glasses and the number is still increasing. We should pay great attention to this problem.
As we know, there are some different causes for near-sightedness. Students always have too much homework to do every day. They have to spend a lot of time doing their home-work. Besides, some of them watch TV overmuch. Others play video games or chat on line for a long time. All this will do harm to their eyes.
As students, we must try our best to take care of our eyes; therefore we should form a good habit of reading, do eyesight exercises regularly and never wear out our eyes.
