有关高中英语倒装句的问题1.No sooner ____ asleep than she heard a knock at the doorA.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 togetherA.However late is he B.However he is lateC.However is he late D.However late he is

1.这题虽然也是倒装，但跟你问的问题无关
这题的时态是过去完成时，当然是用过去分词!
2.however这类的强调语气的词放在举手，主谓是要倒装的
由本来的疑问语序变成陈述语序
另外：however相当于no matter how！

一，因为这句话是过去完成时。在使用倒装的时候，应该把had提到she的前面，其它不用改变。
二，2. 在whatever或however引导的让步状语从句中，常把whatever+名词或however+形容词/副词放在句首。
eg. However difficult the problem may be, we must work it out this evening.
其基本句型是however +形容词/副词放在句首+主语+系动词be
记住这个句型就可以

要用过去完成时
就等于no matter how 啊
how要加形容词
OK？

1.前面有had嘛完成时当然要用过去分词
2.however表程度，修饰形容词.无论他多晚来

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.
