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.
健康狀況
最近的調查表明，在過去的3年中我校學生的健康狀況越來越糟， 患近視的學生已從2002年的78．2％增長到今年的92．5％，而超重的學生已從36％增長到52．4％。由于過多的家庭作業，有將近10％的學生缺乏睡眠；此外，超過15％的學生精神不健康。
為提高學生的健康狀況，我們需要減少家庭作業。惟如此，學生才能得到足夠的睡眠，降低近視率。為保持體形，合理的飲食和鍛煉也應當引起重視。沒有了繁重的負擔，學生也會有良好的精神狀態。
