请问:It is suspected that... 和 It is doubted that...有何区别?
哪一个才是比较正宗的句型?
刘老师:
It is suspected that... 和 It is doubted that...,无法用正宗与否来衡量这个问题。
第一个说法可以有,因为主动语态可以说:People suspect that...
第二个说法不正确,因为主动语态就不说:*People doubt that...
此外,既然doubt 表示“怀疑”之意,那么后面的句子应该是表达“悬而未决”的概念。所以,其从句不可能用that 引导,而应该用whether 或if 引导。
that 引导的句子是陈述一个事件;whether 引导的是一个带有“疑问”的句子。
正宗的说法应该是:把doubted 改为形容词doubtful,主句用whether 或if 引导,也可用that引导。例如:
It is doubtful whether he will be able to come.
It is doubtful if he will be able to come.
It is doubtful that he will be able to come.
你查一下语料库便知。

doubt 的用法:之后应该接什么?
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, 含有doubt的主句需用否定或疑问形式。doubt偶尔也用作不及物动词,常与介词of连用表示“对…抱怀疑或悲观的态度”。
3. 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。
doubt 是表示思想状态的动词,指思维活动的结果,通常不用于进行体。
4. doubt 一般不用于进行体。但偶尔可见如She is always doubting my word.(她总是不相信我的话)这类的句子,句中的现在进行时表示一种“不满”的情绪。
5. 在肯定句中不可以说I doubt so.但在否定句中则可以说I don't doubt so.
在新课标人教版必修二第1单元课文中,有这样一句话:There is no doubt that the boxes were then put on a train for Konigsberg, which was at that time a German city on theBaltic Sea.
在选修六第4单元课文中,也有类似的一句话:There is no doubt that the earth is becoming warmer.
就这两个句子而言,doubt后面的that从句是同位语从句。
网友可能要问,这里,doubt后面的从句为何用that引导,用whether可以吗?为什么下面的句子用whether?
I doubt whether he is at home. 我看他不一定在家。
There is some doubt whether he will come on time. 他能否按时到达不能肯定。
我们发现,用that引导的从句表达了一个陈述而又肯定的事实;用whether引导时则表达了一个带有疑问的情况。那么,在什么情况下由that引导,什么情况下由whether引导呢? 这就要从doubt 的含义说起。doubt一词,无论用作动词还是名词,都表示“怀疑,疑惑”的意思,就是说,当它前面有否定词时,即“没有疑问,毫无疑问”,它的同位语从句就用that引导。反之,就用whether引导。请看下面的例题:
Although most of them have no doubt ______ he will pass the exam, I still think there is some doubt ______ he has really got everything ready.
A. whether; that B. that; whether C. that; that D. whether; whether
答案应选B. 因为:第一个选项之前是no doubt (没有疑问),既然没有疑问,那么,同位语从句就表达了陈述的含义,故用that;第二个选项之前是some doubt (有些疑问),那么,同位语从句就表达了带有疑问的含义,故用whether。
不仅同位语从句,而且宾语从句也是如此。试比较:
I doubt whether she will like the present we bought for her.
I don't doubt that she will like the present we bought for her.

doubt
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”。
2 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。
3 有时在肯定句里也可见doubt接由that引导的从句的情况,这时怀疑的意味已很淡。例如:I doubt that he will come.我想他恐怕不会来。
suspect
suspect的基本意思是指“猜想”或“怀疑”某人〔事〕,也可指“猜想”或者“怀疑”某事已经发生或将会发生,主观色彩较浓,不一定有根据。
suspect是及物动词,接名词、代词、that从句、wh-从句作宾语。可用于被动结构。
It is suspected that是一个很常见的句型,表示that从句内容被认为有可能是真的,尽管没有真凭实据。
It was suspected that the boy was lying.
It is doubbted that很少使用。
It is doubted that he will come.
更常用的是It is doubtful that表示不相信从句的内容是真实的。
