　　中考英語(yǔ)語(yǔ)法it常見(jiàn)句型歸納（20種）

　　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(yǔ)，賓語(yǔ)，表語(yǔ)或狀語(yǔ)。強(qiáng)調(diào)的主語(yǔ)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(wú)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(yǔ)，譯成漢語(yǔ)“直到...才...”，可以說(shuō)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(yǔ)，真正的主語(yǔ)是that引導(dǎo)的主語(yǔ)從句，常譯為“清楚（顯然，真的，肯定...）”是主語(yǔ)從句較常見(jiàn)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(yǔ)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(yǔ)，真正主語(yǔ)是that引導(dǎo)的主語(yǔ)從句。該結(jié)構(gòu)常譯為“據(jù)說(shuō)（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(guò)去分詞是表示請(qǐng)求、建議、命令等時(shí)，that后的從句要用虛擬語(yǔ)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(yǔ)氣（should + 動(dòng)詞原形），should可省去。表示出乎意料，常譯為“竟然”。沒(méi)有這種意義時(shí)，則不用虛擬語(yǔ)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！

　　8、It is time ( about time, high time ) that ...

　　該句型中that后的從句應(yīng)該用虛擬語(yǔ)氣，值得注意的是

　　常用過(guò)去時(shí)態(tài)表示虛擬。

　　有時(shí)也用should+動(dòng)詞原形，should不能省。常譯為“是（正是）...的時(shí)侯”。

　　It is time that children should go to bed.

　　= It is time that children went to bed.

　　9、It is the first ( second ... ) time that ...

　　該句型要和上一個(gè)句型區(qū)別開(kāi)來(lái)。該句型中的that從句不用虛擬語(yǔ)氣，而用完成時(shí)態(tài)。至于用什么完成時(shí)態(tài)，由主句的謂語(yǔ)動(dòng)詞的時(shí)態(tài)決定。如果是一般現(xiàn)在時(shí)，后面從句用現(xiàn)在完成時(shí)態(tài)；如果是一般過(guò)去時(shí)，后面從句則用過(guò)去完成時(shí)態(tài)。該結(jié)構(gòu)中 that可以省去；it有時(shí)用this替換。常譯為“是先進(jìn)（二）...次...”。

　　It is the first time I have been here.

　　= This is the first time I have been here.

　　10、It is ... since ...

　　該句型主要用作處理瞬間動(dòng)詞的完成時(shí)，又要和表示一段時(shí)間的時(shí)間狀語(yǔ)連用的問(wèn)題。主句中是時(shí)間作表語(yǔ)，其時(shí)態(tài)是現(xiàn)在時(shí)或完成時(shí)，since引導(dǎo)的從句通常是一般過(guò)去時(shí)態(tài)，而且是瞬間動(dòng)詞。如果主句是一般過(guò)去時(shí)，從句則用過(guò)去完成時(shí)。

　　It is ( has been ) 5 years since his father died.

　　11、It is ... when ...

　　該句型中的when引導(dǎo)的是一個(gè)時(shí)間狀語(yǔ)從句，主句中的it指時(shí)間，表語(yǔ)由具體的時(shí)間充當(dāng)。常譯為“當(dāng)...的時(shí)候，是...”。

　　It was 5 o’clock when he came here.

　　12、It be ... before...

　　該句型主句中的it指時(shí)間，主句中的時(shí)態(tài)常是將來(lái)一般時(shí)或過(guò)去時(shí)兩種時(shí)態(tài)。主句中的表語(yǔ)多是long, not long, 3 days, 2 weeks等表示時(shí)間段的詞或短語(yǔ)。常譯為“...之后...”。

　　It was 3 days before he went to Beijing.

　　It will be not long before he finishes his job.

　　13、It happens ( seems, looks, appears ) that ...

　　該句型中it是形式主語(yǔ)，that引導(dǎo)的是主語(yǔ)從句，主句中的happen , seem等詞是不及物動(dòng)詞。

　　It happened ( so happened ) that he met his teacher in the street. （碰巧）

　　It seems that he will be back in a few days. （看來(lái)）

　　14、It takes sb. ... to do sth.

　　該句型中的不定式是真正的主語(yǔ)，it是形式主語(yǔ)，句型中的直接賓語(yǔ)是時(shí)間。常譯為“做...要花費(fèi)某人...”。

　　It took thousands of people many years to build the Great Wall.

　　15、It is no good ( use ) doing sth.

　　該句型中的真正主語(yǔ)是動(dòng)名詞短語(yǔ)，主句中的表語(yǔ)可以是no good, not any good, no use, not any use。

　　It is no good learning English without speaking English.

　　16、It doesn’t matter whether ( if ) ...

　　該句型中whether ( if ) 引導(dǎo)的從句是真正主語(yǔ)，該句型常譯為“不論（是否）...沒(méi)關(guān)系...。

　　It doesn’t matter if they are old.

　　17、It is kind ( of sb. ) to do sth.

　　該句型中的不定式短語(yǔ)是真正主語(yǔ)，如果不定式的邏輯主語(yǔ)是由of引起，主句中的形容詞必須是能表示邏輯主語(yǔ)特征的形容詞。常見(jiàn)的有： bad, brave, careless, clever, cruel, foolish, good（好心的）, honest, horrible, kind, lazy, modest , naughty, nice（有教養(yǎng)的）, polite, rude, silly, stupid, wise, wrong（錯(cuò)誤的）等。 這個(gè)句型可以改寫(xiě)為：sb. is kind to do sth.

　　It is kind of you to say so.

　　= You are kind to say so.

　　18、It is necessary ( for sb. ) to do sth.

　　該句型與上一個(gè)同屬一個(gè)句型。如果不定式的邏輯主語(yǔ)是由for引起，主句中的形容詞通常是表示重要性、緊迫性、頻繁程度、難易、安全等情況的形容詞。常見(jiàn)的形容詞有：

　　①important, necessary, natural

　�、趀asy, safe, common, normal, hard, difficult, dangerous, unusual, rare, impossible, pleasant等。

　　在①中的形容詞作表語(yǔ)可以用從句改寫(xiě)， 如：

　　It is important for her to come to the party.

　　= It is important that she ( should ) come to the party.

　　19、It looks ( seems ) as if ...

　　該句型中it無(wú)意義。as if引導(dǎo)一個(gè)狀語(yǔ)從句。常譯為，“看起來(lái)好像...”。如果與事實(shí)不相符合，則用虛擬語(yǔ)氣。

　　It looks as if he is ill.（真的病了）

　　It looks as if he were ill.（沒(méi)有生�。�

　　It seemed as if he were dying.

　　20、We think it important to learn a foreign language.

　　該句型中的it作形式賓語(yǔ)。為了記憶方便我們可稱(chēng)該句型為“6123結(jié)構(gòu)”。

　　“6”指主句中常用的動(dòng)詞：think, believe, make, find, consider, feel；

　　“1”指的是形式賓語(yǔ)it；

　　“2”指的是賓補(bǔ)的兩種形式：形容詞或名詞；

　　“3”指的是真正賓語(yǔ)的三種形式：不定式短語(yǔ)，動(dòng)名詞短語(yǔ)或that引導(dǎo)的賓語(yǔ)從句。

　　We think it our duty to clean our classroom every day.

　　He felt it important learning English well.

　　They found it difficult that they would finish their work in two days.
