题目内容

My mother doesn’t know __________ this morning.   

A.what to do

B.what does do

C.how to do

D.why does do

 

【答案】

A

【解析】

试题分析:“疑问词 + 动词不定式”是英语中常用的一种结构。在句中可以作主语、动词或介词的宾语以及表语。本句的含义是我妈妈不知道今天早晨该做什么,其中what to do做know的宾语。C项是错误的,正确的表示是how to do it。故选A。

考点:疑问词 + 动词不定式充当简单句的句子成分。

点评:“疑问词 + 动词不定式”是英语中常用的一种结构。在句中可以作主语、动词或介词的宾语以及表语。此外,当宾语从句由连接代词who, which, what或连接副词when, where, how等引导时,有时可以与“疑问词 + 动词不定式”结构互相转换。但是,主句中的主语与从句中的主语须一致。
