I have no choice but to wait.I have nothing to do except sleep.

问题描述:

I have no choice but to wait.I have nothing to do except sleep.
这两句子中的but except.如何才能分析它是介词还是实义动词啊?来决定后面接不定式 ...

...have nothing to do except/but ...因为前面有个do所以to do sth.的to省略了,其实多读几遍自然就感觉到了,要是有to反而比较别扭.语法是自然形成的,所以同意 hongqipilang 的说法.
