the departure time of the plane has been postponed,so we have notinging to do but (等)
为什么是wait这个形式
记住这个:have nothing to do but do
这里的 but 后面跟动词原形 wait
另:
除了什么只能做什么.
I can do nothing but do the homework.
无可选择不得不做什么.
He had no choice but to join the party.
除了做什么没事可做.
She had nothing to do but go on working
分析:
but 做介词(except的用法也基本相同),有时后接带to的动词不定式,有时后接不带to的动词不定式.这要看句子前面是否已经有do.
当句子前面有do时,but后面跟的动词不定式通常不用to,其基本结构是:
do nothing (anything) but……;have……to do but.
简单说,就是省略了to的不定式.
不明白可继续提问.
