不用to动词的用法:
1. had better (’d better) do: “你最好做…..”
e.g. It’s freezing outside. You had better put on your overcoat.
2. 使役动词: make, let, have “使某人做某事”
e.g. The teacher has us copy the text twice.
但是被动语态要用to: We are made to copy the text twice by the teacher.
3. 感官动词:see, hear, observe, notice, feel, watch, look at, listen to, etc.
e.g. Suddenly we felt the atmosphere grow tense.
I felt the house shake violently.
但是被动语态要用to: He was heard to sing in the next room.
4. have known (sb) do, have heart (sb) do: “听说,看过,了解”
e.g. I have never known / learnt him cry.
I've heard say that she has left. 我听说她走了
We have never known him lose his temper before.我们从没有见过他发过脾气。
5. would rather than do, would sooner.. than, “宁愿,而不是”:
如果置于句首,后面不接to
e.g. Rather than / Sooner than talk himself, he would listen others. 他宁愿听别人谈,而自己不谈。
Rather than travel by air, I'd prefer to travel a week on a big liner.
我宁愿乘大船走一个星期, 也不愿意乘飞机旅行。
