how to do it和what to do的区别

时间:2023-06-18 19:35文/学帆高考

how to do it和what to do的区别是意思不同、用法不同。英语中表示做什么用what to do,英语中表示怎样做这件事,如何做这件事用how to do it。

what to do和how to do it 区别在哪

1.英语中表示“做什么”用what to do,其中what就是do的宾语,所以do后面不能再加it作宾语了。

2.英语中表示“怎样做这件事,如何做这件事”用how to do it,其中how是副词作状语,it指代前面提过的某件事,do是及物动词,没有it作宾语表达就不完整。

如: I know little about shopping online. Can you show me how to do it.我对网购不怎么了解,你能教我如何网购吗?

注:在“疑问代词+to+不及物动词+介词”的结构中不能缺失介词。如:

When I feel stressed, I don't know who to talk.(错误)

When I feel stressed, I don't know who to talk to.(正确。talk to意思是“跟......交谈”其宾语是who这个疑问代词,没有to就变成talk这个不及物动词后面直接跟who作宾语了,这显然是不正确的。)

例题解析

It's too late for school. I really don't know __________.

A. what should I do B. how to do

C. what to do D. what to do it

【解析】正确答案选C。结合选项可知句意:上学太迟了,我真不知道该怎么办。四个选项中A不是陈述语序,不能作宾语,故排除;B选项中how是副词作状语,do是及物动词,后面必须跟宾语才完整,how to do是个不完整的表达,故排除;C选项中what是疑问代词,作do的宾语,因此what to do这个动词不定式短语表示“该怎么做”,是完整的;而D中代词it是多余的。故只有选C。

【点拨】解答这类试题时,要对疑问副词和疑问代词有所了解。英语中what,who,whom,which,whose是疑问代词,另外,whatever等也可作疑问代词,这些代词在句中可作主语或宾语;when,where,how,why是疑问副词,只能作状语,不能作主语或宾语。

what to do的意思及用法

what to do意为做什么、怎么办,问的是动作的对象,而what是代词在句中中做宾语,所以what to do中不需要再加宾语。例句有:

1、I don't quite know what to do next.

我不太清楚下一步该怎么办。

2、He was considering what to do next.

他在考虑下一步怎么办。

3、I just don't know what to do for the best.

我就是弄不清做什么才好。

4、She never had the least idea what to do about it.

这事怎么办,她一点主意都没有。

5、I don't know what to do with all the food that's left over.

我不知道怎样处理所有这些剩饭剩菜。

6、She explained to them what to do in an emergency.

她向他们说明了紧急情况下应采取的行动。
