【题目】We should always ________ the people who have helped us.

A.be hard onB.be thirsty forC.be afraid ofD.be thankful to

Answer 1

【答案】D

【解析】

句意：我们应该感谢帮助过我们的人。

考查形容词短语。be hard on sb.对某人要求严格；be thirsty for渴望；be afraid of害怕；be thankful to sb.感谢某人。根据空后the people who have helped us可知，我们应感谢帮助过我们的人。故选D。
