第二节语法填空
【解题导语】 充足的睡眠同饮食和健康一样重要。本文主要介绍了睡眠不足造成的影响及研究人员建议公众采取措施解决睡眠不足这一问题。
1．why 解析：考查宾语从句。一项研究分析了为什么我们需要睡眠以及缺乏睡眠的影响。分析句子结构可知，空处引导宾语从句且从句中缺少原因状语，故填why。
2．employees 解析：考查名词。根据空前的Some可知，空处应用名词复数。some employees“一些员工”。employee“雇员，雇工”；employer“雇主，老板”。根据语境可知，空处应填employees。
3．less 解析：考查形容词的比较级。工作中，睡眠不足的雇员会遇到更多的事故且效率较低。根据空前的more可知，此处应用形容词的比较级。[
4．to 解析：考查介词。空前的visits为名词复数，其后常用介词to。
5．caused 解析：考查非谓语动词。cause和它所修饰的名词injuries之间是逻辑上的动宾关系，此处表示“由汽车事故造成的伤害”，故用caused作后置定语。
6．unhealthy 解析：考查形容词。其他研究已经把睡眠质量差与患心脏病、抑郁和不健康的体内脂肪含量等这样的健康问题的风险联系了起来。空处修饰名词amounts且和depression意义相近，故填unhealthy。
7．a 解析：考查冠词。a large amount of是固定搭配，意为“大量，许多”，用来修饰不可数名词。
8．both/their 解析：考查代词。少于这个时间会影响身心能力。both与后面的and构成固定搭配，意为“不仅……而且……”。或结合上文中的“most people”可知，此处也可用their修饰后面的名词abilities，表示“他们的身心能力”。[]
9．breathing 解析：考查非谓语动词。stop doing sth.“停止做某事”，为固定用法。故填breathing。
10．(should) be informed 解析：考查虚拟语气和语态。suggest表示“建议”，后跟宾语从句时从句中要用虚拟语气，即从句中的谓语动词用“should＋动词原形”，且should可以省略。另外，the public与动词inform之间是被动关系，故用其被动形式，因此填(should) be informed。
