it作形式主语，替代主语从句，动词不定式，或动名词短语：

1.作形式主语替代主语从句

⑴It is clear ( obvious，

true，

possible，

certain....) that 从句

常译为＂┅清楚的（显然的，真的，可能的,肯定的．．．）＂

It is very clear that he’s round and tall like a tree.

= That

he’s round and tall like a tree is very clear.

⑵It is important ( necessary，

right，

strange，

natural...) that 从句

常译为┅是重要的(必要的,对的,奇怪的,自然的┅).that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去，建议记住该句型中的形容词。

①It is important that we (should) learn English well.

②It is necessary that he (should) remember these words.

⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that 从句

常译为＂据说（据报道，据悉．．．）＂。

①It is said that he has come to Beijing.

②It is reported that another earth satellite has been put into orbit.

⑷It is suggested ( advised/ ordered / demanded/ insisted/ commanded... ) that 从句.that

后的从句要用虚拟语气（should + 动词原形），should 可以省；常译为＂据建议；有命令．．．）

①It is suggested that the meeting ( should ) be put off.

②It was ordered that we ( should ) arrive there in two hours.

⑸It is time ( about time ，high time ) that从句(虚拟语气:动词用过去时did) ①

It is (high ) time you made up your mind. ⑹It is the first ( second ... ) time that从句(从句用现在完成时

have done )

It was the first ( second ... ) time that从句(从句用过去完成时had done )

常译为＂是第一（二）．．．次．．．＂。

It is the first time I have been here. = This is the first time I have been here ⑺It is a pity ( a shame /an honour/a good thing/a fact,/a surprise/... ) that从句.

that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。

①It is a pity that such a thing ( should ) happen in your class. 这种事竟然发生在你们班

上，真是遗憾！

②It is a pity that he is ill. 他生病了，真遗憾！

⑻It happens (seems，
