    root

    7 月 13, 2020

    1.定义:用作主语的从句叫做主语从句。

    2.构成:关联词+简单句

    3.引导主语从句的关联词有三类:

    (1)从属连词that.

    如:That they were in truth sisters was clear from the facial resemblance between them.

    很明显,她们确是亲姐妹,她们的脸型很相似。

    (2)从属连词whether.如:

    Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。

    (3)连接代词who,whom,whose,what,which,whoever,whatever,whichever

    连接副词where,when,how,why.如:

    What she did is not yet known. 她干了什么尚不清楚。

    How this happened is not clear to anyone. 这事怎样发生的,谁也不清楚。

    Whoever comes is welcome. 不论谁来都欢迎。

    Wherever you are is my home – my only home. 你所在的任何地方就是我的家——我唯一的家。

    难点释疑:

    1.主语从句能用it作形式上的主语。常以it作形式主语的句型有:

    A. It+be+形容词(obvious,true,natural,surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句。如:

    It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。

    It is probable that he told her everything. 很可能他把一切都告诉她了。

    B. It+be+名词词组(no wonder,an honour,a good thing,a pity,no surprise,etc.)+that从句。如:

    It’s a pity that we can’t go. 很遗憾我们不能去。

    It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。

    C. It+be+过去分词(said,reported,thought,expected,decided,announced,arranged,etc.)+that从句。如:

    It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。

    It is reported that China has sent another man-made earth satellite into orbit. 据报道中国又成功地发射了一颗人造地球卫星。

    D. It+seem,happen等不及物动词及短语+that从句。如:

    It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。

    It happened that I was out that day. 碰巧我那天外出了。

    E. 当主语从句出现在感叹句中时,要以it作形式主语,而把主语从句后置。如:

    How strange it is that the children are so quiet! 孩子们这么安静真奇怪!

    2.注意连接代词whoever,whatever,whichever等引导主语从句的含义:

    Whoever comes will be welcome. (whoever=the person who)来的人将受到欢迎。

    Whatever he did was right. (whatever=the thing that)他所做的事情是正确的。

    Whichever of you comes in will receive a prize. (whichever=anyone of you who)你们当中不论哪个进来将会得到奖励。
