把每题的做法说一下 有的地方不明白
He ought to know what to do,( oughtn't he)? ought to的否定式是 oughtn't to
We have to get there at eight tomorrow,(don't we )? have to 的否定式是don't have to
He used to take pictures there,(didn't he )? used to 的否定式是didn't use to
You'd better read it by yourself,(hadn't you )? had better的疑问式式是将had 提前
He would rather read it ten times than recite it,(wouldn't he )?
would rather的疑问式式是将would 提前
Everything is ready,(isn't it )? 代物用it
I don't think he is bright,(is he )?
含think, believe的主从复合句的反义疑问句肯否定形式看主句，主谓看从句。
We believe she can do it better,( can't she)?
Everybody knows the answer,(don't they )?代人用they
We needn't do it again,(need we )? 有情态动词need
Go with me,( will you)?祈使句除Let's开头的用shall we? 其余都用will you?包括Let us 也用will you?
Let's go and listen to the music,(shall we )?
Let us wait for him in the dining room,(will you )?
He must be there now,(isn't he )? 表推测时根据情态动词后的谓语动词变。
It must be going to rain tomorrow,(isn't it )?
Nobody knows about it,(do they )?主语是否定词nobody 指人，所以用do they
希望你能看明白！
