        如果我们把句子当作名词来使用,分别在另一个句子中作主语、宾语、表语和同位语(见下表第二列),于是就构成了四种从句:主语从句、宾语从句、表语从句和同位语从句 。因为以为这四种从句在本质上相当于名词的作用,所以我们把他们统称为名词从句。请看例句:






        Stuart is ugly.

        That Stuart is ugly is a fact..

        That Malaysians don’t speak good English is obvious.


        It is a fact that Stuart is ugly.

        It is obvious that Malaysians don’t speak good English。


        ①It is +过去分词 +that 从句(found, believed, reported, thought, noted…)

        ②It is +形容词 +that 从句(clear, possible, likely, natural, certain, fortunate, necessary, strange…)

        ③It is +名词(短语) +that 从句(a pity, a shame, an honor, a good idea, a miracle…)

        2. 宾语从句。“that+陈述句”在宾语位置即成宾语从句:

        I think (that) you turned off the light.

        We know (that) women love shopping.

        She believed (that) her child was premature.



        My idea is that the students should be more open to each other.

        The reason is that he was careless and irresponsible.(考点)



        The rumor that Tom washed his socks once a month turned out to be untrue.

        Our fathers brought forth upon this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal.

        A saying goes that tomorrow is another day.


        1.主语从句: does she love dog-walking?

        Whether she loves dog-walking or not is unknown.


        I don’t know if/whether whether she loves dog-walking


        My concern is whether you are a student or not.


        They are faced with the problems whether they should continue to play.

        补充:if whether区别


        If he comes or not makes no difference.

        The question is if he will arrive.

        2)if 不和or not直接连用,一般不说 if or not。但可以说 if … or not 。而whether没有此限制。

        I don’t know if or not he arrives.

        I don’t know whether or not he arrives.


        There arose the question where we could get the loan.

        I have no idea what gender he is.

        Why he refused to cooperate with us is still a mystery.

        I don’t know how many letters I have written to her.

        NBA is what I am crazy about.

        How China should develop next is a serious problem.

        Excuse me, can you tell me where the post office is?

        My question is where we are going to have our holidays.

        The point is whose book is the most horrible.

        Whoever comes will be welcomed.

        Whatever is left over is yours

        Do whatever you please.

        Read whichever books you please.

        I'll give it to whichever of you wants it.

        P.S. 最后说明:同位语从句多用that引导,少用whether, if以及代词或副词引导,因为我们多是用陈述句补充名词的内容,而少用一般疑问句或特殊疑问句来补充名词的内 容。







        3)用特殊问句作成分时,只需将疑问句换成 语序。


        It is a curious paradox that we think of the physical sciences as “hard”, the social sciences as “soft,” and the biological sciences as somewhere in between. This is interpreted to mean that our knowledge of physical system is more certain than our knowledge of biological systems, and these in turn are more certain than our knowledge of social systems. In terms of our capacity of sample the relevant universes, however, and the probability that our images of these universes are at least approximately correct, one suspects that a reverse order is more reasonable.
