二、不带to的不定式结构
以下几种情况使用不带to的动词不定式:
1.在固定词组had better之后。注意:had better的否定形式是had better not do sth.。例如:
You had better go home now.你最好现在回家。
It's cold outside. You'd better not go out.外面很冷,你最好不要出去。
2.在let, make, see, feel, watch, hear等感官或使役动词后,要跟不带to的动词不定式作宾语补足语。例如:
I made them give me the money back.我迫使他们把钱还给我。
I didn't see you come in.我没看见你进来。
3.在引导疑问句的why not之后。
"Why not+不带to的不定式"是Why don't you do…的省略,可以用来提出建议或劝告。例如:
Why not go with us?什么不和我们一起去呢?
Why not take a holiday? =Why don't you take a holiday? 为什么不休个假呢?
还有联系动词后面不能加
