When we look around the classroom, we may find that there are many students wearing glasses, they get short-sight. Many years ago, before the popularity of computers, there were not so many people get the short-sight problems, the eye problem is more obvious today, and we need to pay attention to the factors that hurt our eyes. First, the technology products such as computers and TV, they are the main factors that do hurt our eyes, many people use them for a long time, and it is easy to get eye problems. Second, too much attention to reading books also hurts the eyes. Most students focus on the books, they are doing their homework all day, it is suggested that we should take a rest per hour.
当我们环视一下教室的时候，我们可以发现很多学生带上了眼镜，他们有近视眼。很多年前，在电脑变得流行以前，并没有多少人患上近视眼，眼睛问题在今天日益明显，我们需要注意伤害我们眼睛问题的因素。第一，科技产品如电脑和电视是伤害我们眼睛的主要因素，很多人长时间使用科技产品，很容易患上眼疾问题。第二，对书本的过度阅读也伤害眼睛。大部分学生把注意力放在了书本上，他们整天在做作业，我们最好每个小时休息一下。
