根據(jù)it的用法特點(diǎn)可歸納為20個(gè)句型
1. It is + 被強(qiáng)調(diào)部分 + that …
該句型是強(qiáng)調(diào)句型。將被強(qiáng)調(diào)的部分放在前面，其它部分置于that之后。被強(qiáng)調(diào)部分可以是主語，賓語，表語 或狀語。強(qiáng)調(diào)的主語如果是人，that可以由who換用。如果把這種句型結(jié)構(gòu)劃掉后，應(yīng)該是一個(gè)完整無缺的句子。這也是判斷強(qiáng)調(diào)句型與其它從句的方法。
It was about 600 years ago that the first clock with a face and an hour hand was made.
It was they that （who ） cleaned the classroom yesterday.
It was in the street that I met her father.
2. It is not until + 被強(qiáng)調(diào)部分 + that …
該句型也是強(qiáng)調(diào)句型。主要用于強(qiáng)凋時(shí)間狀語，譯成漢語“直到…才…”，可以說是 not … until … 的強(qiáng)調(diào)形式。
It was not until she took off her dark glasses that I realized she was a famous film star.
= Not until she took off her dark glasses did I realize she was a famous film star.
= I didn't realize she was a famous film star until she took off her dark glasses.
3. It is clear （ obvious, true, possible, certain…） that ……
該句型中it 是形式主語，真正的主語是that 引導(dǎo)的主語從句，常譯為“清楚（顯然，真的，肯定…）”是主語從句最常見的一種結(jié)構(gòu)。
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.
4. It is important （ necessary, right, strange, natural…） that …
該句型和上一個(gè)同屬一個(gè)句型。由于主句中的形容詞不同，that 后的從句中要用虛擬語氣（should + 動詞原形），should 可以省去。建議記住該句型中的形容詞。
It is important that we （should） learn English well.
It is necessary that he （should） remember these words.
5. It is said （reported, learned…） that …
該句型中的it 仍是形式主語，真正主語是that 引導(dǎo)的主語從句。該結(jié)構(gòu)常譯為“據(jù)說（據(jù)報(bào)道，據(jù)悉…）”。
It is said that he has come to Beijing.
It is reported that another earth satellite has been put into orbit.
6. It is suggested （ ordered … ） that …
該句型和上一個(gè)同屬一個(gè)句型。主句中的過去分詞是表示請求，建議，命令等詞時(shí)，that后的從句要用虛擬語氣（should + 動詞原形），should 可以省。常譯為“據(jù)建議；有命令…）
It is suggested that the meeting （ should ） be put off.
It was ordered that we （ should ） arrive there in two hours.
7. It is a pity （ a shame … ） that …
該句型中，that后的從句一般用虛擬語氣（should + 動詞原形），should可省去。表示出乎意料，常譯為”竟然“。沒有這種意義時(shí)，則不用虛擬語氣。
It is a pity that such a thing （ should ） happen in your class.這種事竟然發(fā)生在你們班上，真是遺憾！
It is a pity that he is ill. 他生病了，真遺憾！
