高三年级英语语法知识难点总结

高三年级英语语法知识点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。

解释:

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. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。如:

It doesn’t matter whether she will come or not. 她是否来这无关紧要。

It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。

F. 当that引导的主语从句出现在疑问句中时,要以it作形式主语,而把主语从句后置。如:

Is it true that the scientist will give us a lecture next week? 下周那位科学家将给我们作报告是真的吗?

Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗?

G. 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
