廣州新東方冬令營分享：根據(jù)it的用法特點(diǎn)可歸納為7個(gè)句型

廣州新東方冬令營：

　　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(dòng)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(dòng)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(dòng)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！
