doubt 和 suspect 意思相同吗?
下面我们就来比较一下:
一 .如果后面接名词、代词或名词性词组时,两者基本上可通用.例如:
I doubt/suspect the truth of her statement.我对她那番话的真实性表示怀疑.
He says he can cure me,but I still doubt/suspect him.他说他能治好我的病,但我仍对他不放心.
二 .如果后面接 that 从句,意思就截然不同.
doubt 意为“无把握;不相信( question the truth of; don't believe/think )”,怀疑其无.
suspect 意为“有存在或属实的想法;相信或者怀疑其有.例如:
I doubt that he has stolen my watch.我不相信他偷了我的手表.
(怀疑其无:我怀疑他根本没偷我的表)
I suspect that he has stolen my watch.我怀疑 / 猜想他偷了我的手表.
(怀疑其有:我怀疑就是他偷了我的表)
The doctor doubted that he was ill with flu.医生怀疑他没得流感.
(怀疑其无得病)
The doctor suspected that he was ill with flu.医生怀疑 / 认为他得了流感.
(怀疑其有病)
那么,doubt 是不是就没有“怀疑其有”的意思呢?也不是.只是,这时 doubt 更多用于否定句或疑问句中.
例如:
I don't doubt that he is right.我确信他是对的.
I didn't doubt that he would come.我当时相信他会来的.
三 .doubt 还有一特点:即用于肯定句时,多接 whether/if 从句,这时,与 doubt that 从句的意思就不同了,这时意为“不敢肯定”.而 suspect 通常不可接 whether/if 这种从句.
例如:Compare “doubt that” and “doubt whether”
I doubt whether/if he'll come.我不敢肯定他来不来.
I doubt (that) he will come.我怀疑他不会来.(怀疑其无)
It's raining hard.I doubt whether it will be fine tomorrow.雨下得很大,我不敢说明天会晴.
It's raining hard.I doubt (that) it will be fine tomorrow.雨下得很大,我真怀疑明天晴不了.(怀疑其无again)
