宾语从句的否定转移
think、believe 等动词后接宾语从句时，否定要放到主句上。
I don't think he is right.（不是 I think he isn't right.）
要点
- think、believe、suppose、expect、imagine 等后面的否定要转移到主句。
- 转移之后，反意疑问句要与从句保持一致。
- 主语不是第一人称时一般不转移。
- hope 不转移，要说 I hope he won't come.
- think so / think not 是同一层的替代说法：Do you think he will come? — I think so. ／ I think not. —— 这一式不重说整句，只顶住那件事。
- 第一人称才带"我看…"这层委婉：I don't believe we can do it.（我看我们做不到）对比 He doesn't believe we can do it.（只说他本人不信）—— 主语一换，转移的意味就淡了。
- 不走这条路的还有 be afraid：日常说 I'm afraid not（恐怕不行）而不说 I don't be afraid… —— 它自己已带否定意味。
例句
I don't think he is right.
我认为他不对。
I don't believe she will come.
我认为她不会来。
He doesn't think it is a good idea, does he?
他认为这不是个好主意，是吗？
I hope it won't rain tomorrow.
我希望明天别下雨。
I don't suppose they will mind.
我看他们不会介意。
She doesn't expect the letter will arrive so soon.
她没想到这封信会来得这么快。
易错提示
- 转移后翻译时要把否定「还」给从句：I don't think he is right 译作「我认为他不对」。
- hope 不转移，别说 I don't hope…
- 回答这类问句要按事实挑词，不必跟着 not 的位置绕：Do you think it will rain? — No, I don't think so.（我认为不会）—— 英文的 No 紧跟着的是主句那个 think。
