【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。
