華閱文章網1.有沒有It is 名詞 to do的句型
有，可以后面跟名次或名詞短語，或者跟形容詞。
例如1、.It is time ( for sb. ) to do sth. 意為“該是某人做某事的時候了”。
2、It is + 一段時間 +before+ 從句， before 引導的是時間狀語從句，這樣的從句中通常用一般現在時表示將來時間。
3、It is + adj. ( +for sb. / sth. ) +to do sth. 常用于此句式的形容詞有： easy, hard, difficult, possible, impossible, important, necessary, good, bad, exciting, interesting, surprising 等。
4、It is + 被強調部分 +that / who 從句。要注意：強調作主語用的人時可以用 who 或 that ，其它情況下一律用 that .被強調的部分通常是主語、賓語、時間狀語和地點狀語。
* 的五大句型 是什么
你好！it的句型很多的。
1. It is + 被強調部分 + that 。 該句型是強調句型。
將被強調的部分放在前面，其它部分置于that之后。被強調部分可以是主語，賓語，表語或狀語。
強調的主語如果是人，that可以由who換用。如果把這種句型結構劃掉后，應該是一個完整無缺的句子。
這也是判斷強調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 + 被強調部分 + that 。
該句型也是強調句型。主要用于強凋時間狀語，譯成漢語”直到。
才。”，可以說是 not 。
until 。 的強調形式。
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構。
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 。
該句型和上一個同屬一個句型。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 引導的主語從句。
該結構常譯為”據說（據報道，據悉。）”。
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 。
該句型和上一個同屬一個句型。主句中的過去分詞是表示請求，建議，命令等詞時，that 后的從句要用虛擬語氣（should + 動詞原形），should 可以省。
常譯為”據建議；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，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 后的從句應該用虛擬語氣，值得注意的是① 常用過去時態表示虛擬.② 有時也用should + 動詞原形，should 不能省。常譯為”是（正是）。
的時侯。”。
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 。
該句型要和上一個句型區別開來。該句型中的 that 從句不用虛擬語氣，而用完成時態。
至于用什么完成時態，由主句的謂語動詞的時態決定。如果是一般現在時，后面從句用現在完成時態；如果是一般過去時，后面從句則用過去完成時態。
該結構中 that 可以省去；it有時用 this 替換.常譯為”是一（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詞的完成時，又要和表示一段時間的時間狀語連用的問題。
主句中是時間作表語，其時態是現在時或完成時，since 引導的從句通常是一般過去時態，而且是瞬間動詞。如果主句是一般過去時，從句則用過去完成時。
It is ( has been ) 5 years since his father died. 11. It is 。 when 。
該句型中的 when 引導的是一個時間狀語從句，主句中的 it 指時間，表語由具體的時間充當。常譯為”當。
的時候，是。”。
It was 5 o'clock when he came here. 12. It be 。 before 。
該句型主句中的 it 指時間， 主句中的時態常是將來一般時或過去時兩種時態.主句中的表語多是long, not long , 3 days , 2 weeks 等表示時間段的詞或短語。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，that 引導的是主語從句，主句中的happen , seem等詞是不及物動詞. 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。
14. It takes sb. 。 to do sth.該句型中的不定式是真正的主語，it是形式主語，句型中的直接賓語是時間。
常譯為”做。要花費某人。”
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是動名詞短語，主句中的表語可以是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。

5.關于It的六種基本句型和例句
1. 陳述句的強調句，強調陳述句中的某個成分。
為了強調句子中的有些成分，要用強調結構It is(was)+被強調部分+that(who)+其他部分。被強調的成分可以是主語、賓語、狀語，但不能是定語表語和謂語。
這種類型的強調句主要注意一下幾個方面： 1)It在這一結構中作主句的主語，所以即使被強調部分是復數名詞，也要用is或was. e.g. Tom and Mark often come to see me. It is Tom and Mark Who often come to see me. （強調主語） 2）如果被強調部分是時間、地點、方式或原因也不用when, where, how, why， 而用that；強調人時可用who，也可用that. e.g.(1)They set out the day before yesterday. It was the day before yesterday that they set out （強調時間狀語） （2）We put off the sports meet because of the rain. It was because of the rain that we put off the sports meet（強調原因狀語） （3）It was because she was ill that they didn't ask her to do the job. （強調原因狀語從句） 3）被強調部分如果是原句的主語，who或that后面謂語的人稱和數應和原句的主語一致。 — Personally, I think it is the salesmanager, rather than the salesgirls, ____ to blame. —I agree with you. A. is B. that is C. are D. who are 2. 一般疑問句的強調句，只需把is(was)提前。
e.g. (1) Was it in 1939 that the Second World War broke out? (2) Is it Professor Wang who teaches you English? (3) —Was it two months ago _____ you luckily got an opportunity to spend your holiday in Canada？ — _____. John was the lucky dog…… A. when; Not I B. when; Not only C. that; Not all D. that; Not me 3.特殊疑問句的強調句，強調特殊疑問句中的疑問詞。 e.g. (1) Where did you find the wallet? Where was it that you found the wallet (2) When shall we meet? When is it that we shall meet？ 從上面的例子中我們可以看出，特殊疑問句的強調句是由“特殊疑問詞+was(is) it that +陳述句”構成的。
但是當含有特殊疑問詞的強調句型用在賓語從句中的時候，上述句型應改為‘特殊疑問詞+it was( is) that +陳述句“，即采用陳述句語序。 e.g. (1) — where was it ____ the road accident happened yesterday？ — In front of the market. A. when B. that C. which D. how (2) I really don't know _____ you returned the book to me. A. when it was that B. when was it C. when was it that D. when it was 4. 有時可用It might be ……that ……，和It must have been……that……的句型表示強調。
e.g. (1)It might be his father that you are looking for. (2)It must have been his brother that you met. 5. 強調not……until結構中由until引導的短語（或從句）表示時間狀語的句型是：It is(was) not until……+that……+其他部分。 e.g. 1)He didn't marry until forty. It was not until forty that he married. (2)Mr. Yang did not leave the lab until he got everything ready for the experiment. It was not until he had got everything ready for the experiment that Mr. Yang left the lab. (3)_____ he realized it was too late to return home. A. Not until dark B. It was until dark that C. It was not until dark that D. It was dark that注意：如果not……until放在句首時就要用部分倒裝句式，它的語序和在not……until結構中由until引導的短語（或從句）表示時間狀語的句型中的語序不同。
6. 強調詞it與先行詞it的區別。 強調詞it與先行詞it的區別可以通過恢復原句的方式來判斷，即如果把it is……that……去掉后剩下的成分仍然能組成一個完整的句子，這就是強調句型，否則就不是。
It is there that accidents often happen. → Accidents often happen there. 以上就是強調句型，被強調成分是狀語，把it is……that……去掉，還原成后來的非強調句。 It is clear that not all boys like football. 上面的句子如果去掉it is……that……后就成了Clear not all the boys like football.很顯然這不是一個完整的句子，因此不是強調句型，而是由it作先行詞引導的一個主語從句。
7. 其他的一些強調句型： It is/was+時間段+since從句，It +時間段+before從句，It is/was+時間點+when從句。 1)It is/was + 時間 + since …，從……已多久了。
在這個句型中，主句通常用一般現在時，since從句用過去時，表示一個時間點。 e.g.(1)It is five months since I arrived in New York. 我到紐約已五個月了。
（2）It is five months since I was in New York.我離開紐約已經五個月了。 注意：例句中five months是作為一個整體看待的，所以用it is.在這類句子中，終止性動詞表示從動作發生時算起；如果是狀態動詞或持續性動詞，則從動作或狀態結束時算起。
2)It is + 時間+ before …。在這個句型和上面一個句型中，時間都是時間段，如years,five days,twenty minutes等。
不過主句的時態多用一般將來時或一般過去時，從句的時態要根據主句的時態進行變化。Before前的主句如果是肯定的，翻譯成“在……之后才……” 主句如果是否定的，翻譯成“不久就……” e.g.(1)It was long before he gave an answer. 過了好久他才答復我。
（2）It was not long before he worked out the difficult 。
6.英語：It is引導的句型知多少
It wasn't until he came back that I went to bed.直到他回來我才睡覺。（一定要注意被強調句型謂語動詞否
定的轉移，及形式）。
* is high time (time/ about time) (that) 主語+should do / did+其它。（注意從句中的謂語動詞用的是虛擬語氣）It is high time that we should go / went home.我們該回家了。
* is / was said ( reported…)+that+從句. 如：
It was said that he had read this novel.據說他讀過這篇小說。=He was said to have read this novel.
* is impossible / necessary/ strange…that clause.（從句中的謂語用should+do / should have done，其形
式是虛擬語氣。）如：
It is strange that he should have failed in this exam.真奇怪，他這次考試沒有及格。
* is + a pity/ a shame…that clause.（注意從句中的謂語動詞用should do 或should have done 的形式，但
should 可以省略。）如：
He didn't come back until the film ended. It was a pity that he should have missed this film. 他直到電影結束
才回來。他沒有看到這部電影真可惜。
* is suggested / ordered/ commanded /…that +clause.（從句的謂語動詞用should do， 但should 可以省略。）如：It is suggested that the meeting should be put off.有人建議推遲會議。
* is/was+表示地點的名詞+where+從句。（注意本句不是強調句型，而是以where 引導的定語從句。）如：
It was this house where I was born.請比較：It was in this house that I was born. （后一句是強調句型。）
* is / was +表示時間的名詞+when+從句。（注意本句型也不是強調句型，而是以when 引導的定語從句。）如：It was 1999 when he came back from the United States. 請比較：It was in 1999 that he came back from the
United States.
* is well-known that+從句。如：
It is well-known that she is a learned woman.
* is +段時間+since+主語+did. 請比較：
It was +段時間+since+主語+had done. 如：
It is five years since he left here.他已經離開這兒五年了。
It was five years since he had left here. 他已經離開這兒五年了。
* is +形容詞+for+ sb.+ to do. 如：
It is impossible for me to finish this work before tomorrow.我明天之前完成此工作是不可能的。
It is +（心理品質方面的）形容詞+of + sb. + to do. = 主語+ be +形容詞+to do.（常用的形容詞有：kind, stupid;
*作形式主語的常見句型有哪些
【It作形式主語常見句型】 動詞不定式，動名詞或主語從句作主語時，通常把它們放在謂語動詞前，而用it作形式主語，放到句首，常見句型有：1. It + be + 形容詞+主語從句，如： It is uncertain whether he can come to Jenny's birthday party or not. 2.
