有些动词或动词词组可以用动词+疑问词+不定式的结构作宾语。

tell
inquire
explain
例如：

There are so many kinds of tape-recorders on sale that I can't make up my mind which to buy.
有这么多的录音机，我都拿不定主意买哪一种。
3、加do
1） 情态动词 （ 除ought 外） 后。
2） 使役动词 let, have, make后，感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后。
注意：被动语态中不能省去to。例如：
I saw him dance. 我看见他跳舞。
=He was seen to dance.
The boss made them work the whole night. 老板让他们整夜干活。
=They were made to work the whole night.
3） would rather，had better句型后
4） Why… / why no…句型后
5） help 后可带to，也可不带to, help sb （to） do sth：
6） but和except后。but前是实义动词do时，后面出现的不定式不带to。
比较：He wants to do nothing but go out. 他只想出去玩。
He wants to believe anything but to take the medicine. 除了吃这药，他什么都信。
7） 由and, or和than连接的两个不定式，第二个to 可以省去：
8） 通常在discover, imagine, suppose, think等词后作宾补时，可以省去to be。例如：
He is supposed （to be） nice. 他应该是个好人。
