疑问句加to do用法好的话追分

1.疑问词+to do 结构相当于一个名词或代词(短语)的作用,在句中可以作主语、表语、宾语、同位语等如:

I don't know what to do .我不知道做什么?what to do 作know 的宾语.

What to do is still my problem.做什么仍然是我的问题.What to do 作主语.

2.要区别疑问词的词性来决定to do 后面要不要跟宾语如:

I don't know how to do it.我不知道怎样做它.how to do it 也作know 的宾语.

what to do 中do 的宾语是疑问代词what

how to do it 中how 是疑问副词,疑问副词不能作宾语,所以要补上it 或者其他宾语如:them,the thing (s)...

这一句“ The best way to learn English is to experiece the culture”不是 疑问词+ to do 的结构哟.

这一句是正确的:I have no idea how to deal with it.(how to deal with it做名词idea的同位语)
