推荐答案 2014-11-13
疑问词+ to do其实就是宾语从句的省略：
I don't know [when to do it].=I don't know [when I should to do it].
I don't know [where to do it].=I don't know [where I should do it].
I don't know [how to do it].=I don't know [how I should do it].
I don't know [What to do].=I don't know [What I should do].
可以看出do的主语都是I，同时do需要宾语[when，where，how都是疑问副词不能做do的宾语]
所以需要it出现做do的宾语；但是what是疑问代词可做do的宾语，不再需要it

D

to do
答：
宾语从句中的关系副词，只有
how
可以直接跟动词不定式意为如何去做（不定是式
to
do
sth有将来意思）所以A C排除掉！
what
是代词可以做宾语，该句中it 已经做了to do的宾语，所以无需what如果去掉it 则答案只能选c！还有疑问就留言，希望答案能满意 ...

选哪个答案...
答：
答案：BCD 解释：1、这里除了
what
之外，其余答案都是正确的。2、what 是疑问代词，在“疑问词+不定式”结构中要充当后面动词的宾语，而后面已经有了宾语it，所以答案A错误。
how

都是疑问副词，在句中作状语。用不同的疑问词，句意就不同。希望我的回答能够帮到您，祝学习进步！ (*^...
