do nothing but ___后面是啥,忘记了to do 还是 do He could do nothing but 后面跟原型还是不定式 do nothing but good do nothing but do,后面的do有没有时态变化? can do nothing but do I can do nothing but They could do nothing but ___ (wait) at home什么时态 NOTHING BUT 后面的动词是ING还是TO DO的形式? there is nothing to do but to do 还是there is nothing to do but do do+but to do/but do的用法我只是不明白下面两句中为什么一句用to do 一句用do.eg1:I have nothing to do but cry.eg2:There was nothing for them to do but to remain silence.我只知道在but前面有do时后面跟do,但不明白为 But have 《Nothing》 to do with you but have nothing to do with you people can do nothing but wait 翻译 now we can do nothing but waitting She could do nothing but ____(cry) Nothing but tears.I can do anyting! do nothing but do 与have no choice but to do 与can't but do but作为介词时后面怎么能接不定式?There is nothing to do but watch TV.介词有接动词不是用ING 形式么?
