health
a recent survey shows that the health of the students in our school has been going from bad to worse in the past three years. the number of short-sighted students has increased from 78.2% in 2002 to 92.5% this year,while that of overweight students from 36% to 52.4%. nearly 10% more students don't have enough sleep because of more homework. besides, over 15% more students become mentally unhealthy.
to improve students'health, we call for less homework. only in this way can students get plenty of sleep and be more healthy. proper diets and exercise should also be paid attention to so that they won't easily put on weight. with their heavy burdens removed, students can then keep in normal mental health.
健康状况
最近的调查表明，在过去的3年中我校学生的健康状况越来越糟， 患近视的学生已从2002年的78．2％增长到今年的92．5％，而超重的学生已从36％增长到52．4％。由于过多的家庭作业，有将近10％的学生缺乏睡眠；此外，超过15％的学生精神不健康。
为提高学生的健康状况，我们需要减少家庭作业。惟如此，学生才能得到足够的睡眠，降低近视率。为保持体形，合理的饮食和锻炼也应当引起重视。没有了繁重的负担，学生也会有良好的精神状态。
