某英文报刊正在征集有关中学生生活的文章。假设你是李华，下面是你校学生近视情况的调查结果。请你根据调查结果用英语写一篇文章投稿，并在文中提出保护眼睛的建议。
| 年级 | 七年级 | 九年级 | 高三 |
| 近视率 | 23% | 35% | 70% |
A possible version:
A recent study in our school shows that more and more students have become near-sighted. The study says that 70 percent of Senior Three students are near-sighted. It also says that 35% of Grade Nine students are near-sighted, but it was only 23% when they were in Grade Seven.
I think the main causes are as follows. First, we have to do a lot of homework, especially in Grade Nine and Senior Three. Second, some of us spend too much time in front of the computer. Furthermore, some students often read lying in bed or in dim light.
Therefore, we must allocate time for our lessons scientifically, spend less time in front of the computer, and develop good reading habits. Most importantly, we must allow our eyes a rest during work from time to time. Only in this way can we prevent our eyes from being near-sighted.
