UNIT 01
It句型
It句型主要有三個方面：
1. it引導的強調句型；
2. it作形式主語或者形式賓語；
3. it和since, before, when等連用。
為了提高同學們的應變能力，現對it引導的一些常見句型歸納總結如下：
1.It be+被強調成分+that/who-clause強調句型
用被強調成分是“人”時，連詞用that或who都可以，否則，只能用that，而且，be動詞只能用is 或was 兩種形式。
例It was two years ago that he made an important invention.（原句是：He made an important invention two years ago.）就是在兩年之前，他做出了一項重要的發明。
It was at 6 o’clock that he practiced playing the violin in the morning.（原句是：He practiced playing the violin at 6 o’clock in the morning.）他早上六點鐘的時候練習拉小提琴。
辨It was 6 o’clock when he began to practice playing the violin in the morning.（早上他開始練習拉小提琴時是在六點鐘）這是含有狀語從句的復合句，而非強調句型，it指時間，it was 6 o’clock. 即“六點鐘了。”
拓在not... until...句型中，強調until引導的狀語從句時，用It is/was not until+被強調成分+that-clause結構。如：
I didn’t realize she was a famous film star until she took off her dark glasses. 直到她摘下墨鏡我才意識到她是一位著名的電影明星。
變為強調句即：It was not until she took off her dark glasses that I realized she was a famous film star.
考It was not until near the end of the letter ______ she mentioned her own plan.（天津高考）
A. that
B. where
C. why
D. when
選A。此處考查固定句型not... until... 的強調句，其句型結構應為：It is/was not until... that+句子，故本題應選A。
2.It takes (sb.) some time/energy to do sth. 花（某人）……時間/精力做某事
用此句型中it是形式主語，真正的主語是后面的動詞不定式。
例It took me three hours to finish my homework. 我花了三個小時才完成作業。
3.It be+adj./n.+for sb. to do sth.（for sb.表示動詞不定式動作的執行者)
It be+adj.+of sb. to do sth.（of sb.既表示動詞不定式動作的執行者又表示人所具備的性質或特征）
用此句型中it是形式主語，真正的主語是后面的動詞不定式。
例It’s important for us to have a good command of English. 掌握好英語對我們來說是重要的。
It’s kind of him to put us up for the night. 他為我們提供住宿，真是太好了。
4.It is said/thought/hoped/believed/reported/suggested... that... 據說/認為/希望/報道/建議……
用此句型中it是形式主語，真正的主語是后面that引導的從句，即主語從句。
例It is said that he is studying abroad. 據說他正在國外留學。
拓此句型可以用下面的形式表達相同的意思：
Sb. is said/thought/hoped/believed to do sth...（注意：suggest不適用于這種轉換）
It is said that he is studying abroad.=He is said to be studying abroad.
5.主語+think/consider/believe/make/feel+it+adj./n.+for sb./of sb.+to do sth. 某人認為/使/覺得做某事對于某人來說是……
用此句型中it是形式賓語，真正的賓語是后面的不定式。
例I feel it foolish of him to believe such a man. 我覺得他太傻了，竟然相信這樣的人。
The timely rain had made it possible for the crops to grow well. 這場及時雨使得莊稼可以很好地生長。
考No matter where he is, he makes ______ a rule to go for a walk before breakfast.（陜西高考）
A. him
B. this
C. that
D. it
選D。句意：無論在哪兒，早餐之前散散步都是他的老規矩。由句意可知to go for a walk before breakfast是真正賓語，a rule 為賓補，故此處需用it充當形式賓語。
6.It be+時間+before-clause
用“It was (not)+時間段+before+一般過去時”意為“過了一段時間才……；沒過多久就……”；“It will (not) be+時間段+before+一般現在時”意為“多久才……；不久就……”。
例It was not long before she learned those poems by heart. 她沒過多久就背會了那些詩歌。
It was long before the police arrived. 過了很久警察才來。
It will be hours before he makes a decision. 要過好幾個小時他才會做出決定。
It will not be hours before we meet again. 要不了幾個小時我們還會再見面的。
考John thinks it won’t be long ______ he is ready for his new job.（湖南高考）
A. when
B. after
C. before
D. since
選C。句意：約翰認為不久他就能為他的新工作做好準備。所填詞引導狀語從句，構成It will not be+時間段+before狀語從句，意思是“用不了多久就……”。
7.It is/has been+時間段+since... 自從……以來多久了
用該句型中since從句的謂語動詞需使用一般過去時。
例It is three years since I last saw you. 自從我上次見到你到現在已經三年了。
考As is reported, it is 100 years ______ Tsinghua University was founded.（四川高考）
A. when
B. before
C. after
D. since
選D。句意：據報道，自從清華大學建校以來到現在已經有一百年了。此處需用It is... since... 句型，表示“自從……已經有……”，故本題選D。
8.It is+time for sth.=It’s time to do sth. 到了該做某事的時候了
用如果要具體說明該某人做某事的時候了，可以用It’s time for sb. to do sth.
例It’s time for us to leave. 到了我們該走的時候了。
9. It’s one’s turn to do sth. 輪到某人做某事
例It’s your turn to answer the question. 輪到你回答問題了。
10.It’s no use(good) doing sth. 做某事是沒有用的
