Question

【题目】My mother always teaches me how ________ water in my daily life. That really helps me develop a good habit of using water.

A.to saveB.savingC.savesD.saved

Answer 1

【答案】A

【解析】

句意：我妈妈在日常生活中总是教我如何节约用水。这确实帮助我养成了用水的好习惯。

考查疑问词加不定式，to save动词不定式；saving动名词；saves动词三单形式；saved过去式。观察句子，这里应该是疑问词加不定式“how to do sth”表示怎样做什么，故选A。
