I think he must be unhappy without me.（反意疑問句）I think he must be unhappy without me, ________ ________?

熱心網友

凡有I think \I suppose \I guess 之類的句子改反意疑問句，一般是將后面部分作改動，你可以這樣理解：我認為他沒有我就會不開心，他是不是這樣呢？但如果改前面部分就不妥當了：我認為他沒有我就會不開心，我是不是這樣認為呢？這種問題有什么意義呢？還有指出一點，句中為肯定，附加疑問就為否定，反之亦然，該句中unhappy雖有否定意義，但當作肯定，所以應為I think he must be unhappy without me, mustn't he?修正一下:must作判斷時,只考慮后面部分,所以正確的應為:isn't不過下面已有人說了,我是后來修改的,要采納的話還是采他們的吧^_^

be代表肯定，跟unhappy沒有關系所以用isn't答案是：I think he must be unhappy without me, isn't he?

I think he must be unhappy without me, ________ ________?doesn't he?

does he?

mustn't he?unhappy雖有否定之意但在句中不表否定,且這是一句賓語從句，主語為第一人稱，w謂語動詞為think（如果賓語從句中主語為第一人稱，謂語動詞為think、suppose、believe、guess等詞的話，反意疑問句看賓語，這句話的賓語為he must be unhappy without me），所以應為mustn't he記住，像上面所說的這類賓語從句要否定前置，如把這句話改為否定應該為：I don't think he must be unhappy without me.而不是 I think he musnt't be unhappy without me.

我認為虛里煙的答案很好！

應該是 isn't it.陳述部分有must 的疑問句，疑問部分根據實際情況而定。例如：　　He must be a doctor, isn't he?　　You must have studied English for three years, haven't you? / didn't you?　　He must have finished it yesterday, didn't he?正如郎那度所說的一樣I think 是插入語，判斷時不用管它，而改反意疑問句時must也無須管它的·
