[语法剖析]

1.

That they are true friends is obvious.

很显然他们是真正的朋友。

What he did really satisfied us all.

他做的事确实让我们大家满意。

2．常以it作形式主语的句型

(1)It＋be＋形容词(obvious, true, natural, surprising, possible, likely, certain, clear, probable, etc)＋that从句

It is certain that she will do well in this exam.

可以肯定她这次考试一定会考得不错的。

It is quite clear that the ear of the elephant is like a huge fan.

很显然，大象的耳朵像一把大扇子。

(2)It ＋be＋名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc)＋that从句

It is no wonder that she was so upset.

难怪她如此心烦意乱。

It's a pity that I can't attend your birthday party.

真可惜我不能参加你的生日宴会。

(3)It ＋be＋过去分词(said, reported, thought, expected, decided, announced, arranged, etc)＋that从句

It is said that another shopping mall will be built in our city.

据说我们城市将再建一座大型购物中心。

(4)It seems/happens/appears/turns out/occurs等不及物动词或短语＋that从句

艾丽丝似乎根本不会来参加晚会。

It turned out that nobody remembered the address.

(5)It doesn't matter(makes no difference, etc)＋连接代词或连接副词引导的主语从句

It doesn't matter whether she will come or not.

她是否要来没有关系。

3．主语从句易混点辨析

(1)that与what

①that引导主语从句时，不作任何句子成分，只起连接作用。多数情况下，that引导的主语从句常放于句末，用it作形式主语。

②what引导主语从句时，在句中作主语、宾语、表语和定语。

That she survived the accident is a miracle.

她在事故中幸免于难简直是奇迹。

What you need is more practice.

你所需要的是更多的练习。

(2)who与whoever

①who引导的从句的内容带有疑问性。

②whoever则表示泛指，相当于anyone who。

Who will give us a speech is unknown now.

谁将向我们发表演讲现在还不知道。

Whoever wins the prize may get the car.

无论谁获奖都可以获得这辆车。
