题目内容

14．_____ the workers'working conditions，the boss will allow them to have a coffee break．（　　）

A．

Improving

B．

To improve

C．

Having improved

D．

Improved

分析为了改善工人的工作环境，老板会允许他们中途休息喝咖啡．

解答答案是B．本题考查动词不定式表目的；根据句子语境判断"allow them to have a coffee break（允许他们中途休息喝咖啡）"的"目的"是"改善工人的工作环境"，所以需要的是表示目的非谓语动词；在非谓语动词中只有动词不定式可以做目的状语，故选B．

点评首先判断选项中的动词在句中是以谓语还是非谓语形式出现，然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断．要关注常见非谓语动词的搭配．
