Answer 1

1.Do you think it is right? —Yes,(C ).
A.I don't think B.I think C. I think so D.I don't think so.意思是，是的，我认为这是对的。AB用法不对，D应该是no,i dont think so. (前后要一致）
2.Wash your hands right now,Jane.Don't (B )your hands dirty.
A.get B.keep C.have D.let
keep sth + adj. 是使什么东西保持某种状态的意思。

3.Your father works in a factor,(C但应该是doesn't he 男他)?
A.isn't he B.don't she C.doesn't she D.aren't she
反意疑问句。WORK 是实意动词，用助动词”do"的适当形式来反问。
4.Must we finish writing these words?No, you(D ).
A.mustn't B.can't C.may not D.needn't
回答“MUST”疑问时，否定回答用NO，YOU NEEDN'T.后者“NO，YOU DON'T HAVE TO。”意思是“你们不需要把这些单词抄写完。”
有疑问的话，给我留信息吧。
