问题描述:

What he wanted to do was——A?——his hands of it.A.washB.to have washedC.washingD.to be washing

C 用ING形式作表语

A 这是一个强调句,而且强调的是谓语,我们知道,强调句强调谓语是,有主要两种,一是在动词前加do 的各种时态,二则是 what sb. ......was to ..... 比如:what I did was to remenber it . 这句中表语的to省略,是因为前面带to了。 希望你明白了。

A 这是因为what he wanted to do 是 what he wanted himself to do 的省略,是这句的主语从句.英语中规定句子中前面的从句有do 或者do 的某种形式,其后的不定时(短语)省to , 所以该句的表语(to) wash his hand...

A 不定式作表语,表示具体事情。省略to是因为主语中有动词do.
