but 的具体用法是什么?
He did nothing but stay idel.
He had no choice but to give in.
一句有to,一句没有to
He did nothing but stay idel.
He had no choice but to give in.
一句有to,一句没有to
我告诉你个口诀:“有do,无to;无do,有to”,
在but的前面如果出现了do,did,does的话,but 后面的to就可以省略,
另外,此类的用法,还有except 和主系表结构,也是一样的.
e.g.They did nothing but wait.
She did nothing except look at the photo.
反过来,but的前面如果没有do,did,does,but 后面就用to
e.g.There is no choice but to wait.
主系表句型里:主语不带“do”,表语则用to
主语带“do”,表语的 to可用可不用
e.g.Your job is to reply emails from the customers.
The only thing I can do now is (to) go on by myself.
主语里的定语从句有个do
