2016年英语三级考试答案|2016年成人英语三级考试语法专项备考宝典(1)

　　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。
