不定式不带to的问题
1)在情态成语之后，即在would rather/would sooner/would(just) as soon(宁愿)，may/might as well(不妨)，cannot but/cannot help but之后。例如：
You can’t help but respect them.
Since it’s a fine day we might as well walk.
2)在“使役动词+宾语”之后，即在let, have, make之后。例如：
Let there be an end of this misunderstanding.
He won’t have us criticize his work.
Abby made him stay to tea.
3)在“感觉动词+宾语”之后，即在see, hear, observe, notice, feel, watch之后。例如：
We feel the house shake.
I didn’t hear you say that.
4)在介词except/but之后
如果except/but之前有动词do的某种形式，其后通常用不带to的不定式，否则带to。例如：
They did nothing except work.
There’s no choice but to wait.
