As it is known to us, fewer and fewer students do sports regularly, what makes them weak and easily tiring. There are many reasons about this. First of all, some of the students complained that they have too many homework, resulting in less time to take exercise. Beside, some of them think that it is very difficulty for them to keep doing exercise, because it is a very hard thing. Because lack of physical activities, many students are in poorly health. I suggested that our school must take measures to encourage more students to take part in sports. For us students, no matter what busy we are, it is necessary to spare any time to do exercise.

【答案】①去掉it

②what→which

③for→about

④complained→complain

⑤many→much

⑥Beside→Besides

⑦difficulty→difficult

⑧Because后加of或Because→For

⑨must改为should/去掉

⑩what→how

【解析】文章分析了现在学生缺乏体育锻炼体质下降这一现象的原因和作者自己的建议。
（1） 删除it.考查定语从句。as引导的是一个非限制性定语从句，as代替整个主句，在定语从句中充当主语。It多余，故删除it。
（2）what改为which. 考查定语从句。此处是非限制性定语从句，指代前面整个句子，要用which引导，不用what，故what改为which。
（3）about改为for. 考查介词。此处指对于这个问题有许多原因，表示“对于”用for，故about改为for。
（4） complained改为complain. 考查时态。文章叙述了一个事实情况且全文是现在时，结合上下句可知，此处也用现在时，故 complained改为complain。
（5）many改为much. 考查形容词。many修饰可数名词，much修饰不可数名词。此处修饰不可数名词homework用much，故many改为much。（6）Beside改为Besides. 考查相似词。Beside是介词，意为“在……旁边”；Besides是副词，意为“此外，而且”。此处表递进，用Besides，故Beside改为Besides。
（7）difficulty改为difficult. 考查形容词。difficulty是名词“困难”，difficult 是形容词“困难的”。此处是形容词作表语，故difficulty改为difficult。（8）Because后加of. 考查同义词。表示原因时，Because引导原因状语从句后加句子；Because of后加词语；lack of physical activities是词语，故Because后加of。
（9）must改为should或去掉. 考查虚拟语气。句意：我建议学校采取措施鼓励更多的学生参加体育锻炼。动词suggest “建议” 后的宾语从句用虚拟语气，即should+动词原形，should可以省略。故 must改为should或去掉。
（10） what改为how. 考查副词。句意：对于我们学生无论多么忙，挤出一些时间锻炼是必要的。修饰形容词busy，表示无论怎样用how，故what改为how。
