求翻译：我校越来越多的学生近视为了了解原因并采取相应措施，学校针对此问题进行了问卷调查结果如下：接近90%的认为作业量太大是主要原因，他们表示每天晚上他们写作业3-4个小时得不到充分休息，根本没有放松的时间有时他们太困了不换衣服就睡着了。对此有人已经受不了了。除了作业量大， 使事情更糟的是,学生缺乏锻炼身体的时间。我认为学校需要采取措施，例如他们应该减少学生的作业量，缓解学生压力。是什么意思？

A growing number of students in our school and take the appropriate measures in order to understand the causes of myopia, school survey results for this problem are as follows: close to 90% think the job is too big is the main reason, homework in the evenings they 3-4 they said hours don't get enough rest, simply no time to relax and sometimes they don't change clothes to sleep too sleepy. It was already can't take it anymore. In addition to the large amount of job, makes things worse is that the students ' lack of time to exercise. I think schools need to take measures, for example they should reduce the amount of student jobs, easing pressure on students.
