怀疑名词英文

doubt用作动词表示怀疑，不信任，不确定；用作名词的基本意思是“怀疑,疑虑”,还可表示“未确定”。可用作可数名词,也可用作不可数名词。

一、doubt用作动词

1、doubt的基本意思是对事〔物〕的真实性等表示“怀疑”或“不信任”,有时甚至在调查研究之后仍“难以确定”。也常用来表示对宗教信条等持有疑虑。

2、doubt多用作及物动词,可接名词、代词、动名词、带疑问词的动词不定式或that/wh-/if从句作宾语,也可接以“(to be+) n./adj. ”充当补足语的复合宾语。接that从句作宾语时, that前有时可加but。

也许他改变了主意,但我表示怀疑。

5、在疑问句或否定句中, doubt的宾语从句应用that引导; 在肯定句中,则应由if〔whether〕引导。

二、doubt用作名词

1、doubt用作名词的基本意思是“怀疑,疑虑”,还可表示“未确定”。可用作可数名词,也可用作不可数名词。

2、doubt后可接介词about〔of, on〕引起的短语表示“对…怀疑”。

他是个贼难道还有疑问吗?
