高一必修四英语语法问题
_____twice,the postman refused to deliver our letters unless we chained our dog.这里填Bitten,为什么不可以填Being bitten,做原因状语从句?
You must have finished reading the book I lent you yesterday,_____这里填haven’t you为什么不填mustn't you?
_____twice,the postman refused to deliver our letters unless we chained our dog.这里填Bitten,为什么不可以填Being bitten,做原因状语从句?
You must have finished reading the book I lent you yesterday,_____这里填haven’t you为什么不填mustn't you?
1.感觉填 Having been bitten 更好点,Bitten勉强可以.
如果使用being done结构做状语,则表明该动作和谓语动作同时进行,但是根据句意,这两个动作明显是有先后关系的.
即：先被狗咬过两次,再拒绝去送信
2.如果用must/can/may等结构表示推测时,句子的反意疑问句和这些情态动词没有关系.
而是要考虑句子的实际时态下的谓语结构,再进行相应变化.
此题如果去掉must,正常时态为：You have finished reading the book I lent you yesterday,所以其反意疑问句为：haven't you?
再如：It must have rained last night,didn't it?
因为去掉must后,句子为：It rained last night,所以是didn't it.
