有关高中英语倒装句的问题
1.No sooner ____ asleep than she heard a knock at the door
A.had she fell B.had she fallen
为什么要用过去分词而不用过去式?
2.____ ,Mother will wait for him to have dinner together
A.However late is he B.However he is late
C.However is he late D.However late he is

1.由于动作的先后顺序,故前一个动作要用过去完成时.而且,就算如果用过去式得话,也应该是No sooner did she fall
2.However late=No matter how late无论多晚.
此题严格说,不是倒装的范畴,只能说however来修饰形容词late.
