it用法一直是高考考查的熱點之一，現(xiàn)就2007年高考試題，對此用法考點作逐一解析如下：

一、考查it作形式主語和形式賓語

1. ____ felt funny watching myself on TV. （全國II）

A. One B. This C. It D. That

解析：答案為C。分析句子結(jié)構(gòu)可知，本句是it作形式主語，watching myself on TV作真正主語的句型。one, this, that都不能在句中作形式主語。

2. ____ worries me the way he keeps changing his mind.（山東）

A. This B. That C. What D. It

解析：答案為D。分析句子結(jié)構(gòu)可知，本句是it作形式主語，the way he keeps changing his mind作真正主語的句型。this, that, what都不能在句中作形式主語。

3. He didnt make ____ clear when and where the meeting would be held.（天津）

A. this B. that C. it D. these

解析：答案為C。分析句子結(jié)構(gòu)可知，本句是it作形式賓語，when and where the meeting would be held作真正賓語的句型。this, that, these都不能在句中作形式賓語。

TIPS：

（1）一般來說，當it作形式賓語，其后常接形容詞、少數(shù)名詞作賓語補足語。能夠后接it作形式賓語的通常是表示“認為”的謂語動詞，如：think,consider, feel, find以及make（使）等。

（2）在謂語動詞appreciate, like, dislike, hate, enjoy, love, prefer, see to（保證）, think of, depend on等詞或詞組后也可接it作形式賓語，指代if,when或that從句所包含的內(nèi)容。

①Id appreciate ____ if you would like to teach me how to use the

computer.（06山東）

A. that B. it C. this D. you

②I like ____ in the autumn when the weather is clear and bright.（04河南）

A. this B. that C. it D. one

③Ill see to ____ that there are enough tickets for you.

A. one B. that C. it D. this

[參考答案]①B ②C ③C

（3）使用it作形式賓語的常用句型結(jié)構(gòu)為：主語+think（consider, feel,find, make）+it（形式賓語）+形容詞或名詞（賓補）+不定式復(fù)合結(jié)構(gòu)或名詞性從句（真正賓語）。

①I think it a duty for us to help others in trouble.

我認為幫助處于困境中的人是我們的一種職責。

②They want to make it clear to the public that they do an important and necessary job.

他們想要使公眾明白，他們做的是一項重要且必要的工作。

二、考查it強調(diào)句型

1. I dont mind her criticizing me, but ____ is how she does it that I

object to.（江西）

A. it B. that C. this D. which

解析：答案為A。這是it強調(diào)句型，強調(diào)賓語從句“how she does it”，將原句還原后為“I object to how she does it”。

2. It ____ we had stayed together for a couple of weeks ____ I found we had a lot in common.（浙江）

A. was until; when B. was until; that

C. wasnt until; when D. wasnt until; that

解析：答案為D。這是it強調(diào)句型，強調(diào)的是時間狀語從句“not until we had stayed together for a couple of weeks”，將原句還原后為“I didnt find we had a lot in common until we had stayed together for a couple of weeks”。題意為“直到呆在一起若干星期后，才發(fā)現(xiàn)我們之間有這么多的相似點”。

3. It is not who is right but what is right ____ is of importance.

（重慶）

A. which B. it C. that D. this

解析：答案為C。這是it強調(diào)句型，強調(diào)的是主語從句“not who is right but what is right”，將原句還原后為“Not who is right but what is right is of importance”。

TIPS:

(1)判斷是it強調(diào)句型還是定語從句的方法是：去掉“It is（was）…that”后，若全句語法、語意仍然完整，即可斷定為強調(diào)句型，否則，可當定語從句來處理。

(2)強調(diào)句型中的it無詞義，但絕不可用this, that代替。

(3)is/was（不可用are/were代替）由原句的謂語時態(tài)來決定，現(xiàn)在時與將來時用is，過去時用was。

(4)強調(diào)主語時，原句謂語應(yīng)與強調(diào)的主語在人稱、數(shù)上保持不變。

(5)被強調(diào)的對象為人時，可用that/who（若強調(diào)的對象人作賓語，也可用whom）。其他情況一律用that。

(6)對人稱代詞強調(diào)時，應(yīng)保持人稱代詞格不變。

(7)強調(diào)句型的陳述式為It is/was+被強調(diào)的成分+that/who+原句的其他成分。

(8)強調(diào)句型的一般疑問式為Is/Was it+被強調(diào)的成分+that/who+原句的其他成分？

(9)強調(diào)句型的特殊疑問式為疑問詞+is/was it that/who+原句的其他成分？

三、考查it時間句型中狀語從句連詞的選用

1. ——He got his first book published. It turned out to be a bestseller.

——When was ____?

——____ was in 2000 when he was still in college.（浙江）

A. that; This B. this; It C. it; This D. that; It

解析：答案為D。由第二空得知此處考查的是It+be+時間+when引導(dǎo)時間狀語從句，it用來表示時間，故排除A、C；又因為兩人敘述的是過去發(fā)生的事情，所以要用that來表示，this常用于表示下文要提到的事。

2. He was told that it would be at least three more months ____ he could recover and return to work.（江西）

A. when B. before C. since D. that

解析：答案為B?！癐t+be+一段時間+before引導(dǎo)時間狀語從句”肯定式意為“多久以后才……”；否定式意為“沒過多久就……”。本句句意為“他被告知至少在三個多月后他才能康復(fù)并重新工作”。

3. The field research will take Joan and Paul about five months; it will be a long time ____ we meet them again.（安徽）

A. after B. before C. since D. when

解析：答案為B?！癐t+be+一段時間+before引導(dǎo)的時間狀語從句”肯定式意為“多久以后才……”；否定式意為“沒過多久就……”。本句句意為“很長時間以后我們才能再次見面”。

TIPS:

（1）“It+be+一段時間+before引導(dǎo)的時間狀語從句”肯定式意為“多久以后才……”；否定式意為“沒過多久就……”。

（2）“It+be+時間+when引導(dǎo)的時間狀語從句”中it指時間，一般具體時間前無介詞，主從句謂語時態(tài)一致，意為“當某事發(fā)生時，時間是……”。

——Did Jack come back early last night?

——Yes, it was not yet eight oclock ____ he arrived home.（05福建）

A. before B. when C. that D. until

（3）“It+be+一段時間+since引導(dǎo)的時間狀語從句”since從句謂語時態(tài)必須是一般過去時或過去完成時，若since與延續(xù)性動詞連用，則意為“某人不做某事已多久了”；若since與短暫性動詞連用，則意為“某人做某事已多久了”。

That was really a splendid evening. Its years ____ I enjoyed myself

so much.（05安徽）

A. when B. that C. before D. since

四、考查it與one、that的區(qū)別

1. ——Have you heard the latest news?

——No, what ____?（全國I）

A. is it B. is there C. are they D. are those

解析：答案為A。news為不可數(shù)名詞，it用來代替不可數(shù)名詞或單數(shù)可數(shù)名詞，特指前面提到的“同類同物”。

2. In my opinion,life in the twenty-first century is much easier than ____.（安徽）

A. that used to be B. it is used to

C. it was used to D. it used to be

解析：答案為D。it用來代替不可數(shù)名詞或單數(shù)可數(shù)名詞，特指前面提到的“同類同物”；that常用來替代帶定冠詞的不可數(shù)名詞或單數(shù)可數(shù)名詞，構(gòu)成that of…的形式，表示“同類異物”；used to be 表示“過去曾經(jīng)是”；be used to則表示“習慣于”。

3. Little joy can equal ____ of a surprising ending when you read

stories.（四川）

A. that B. those C. any D. some

解析：答案為A。that 常用來替代帶定冠詞的不可數(shù)名詞或單數(shù)可數(shù)名詞，構(gòu)成that of…的形式，表示“同類異物”。此句中that=the joy。句意為：沒有什么比得上讀到一個出人意料的故事結(jié)尾更快樂的事。

4. The information on the Internet gets around much more rapidly than ____ in the newspaper.（遼寧）

A. it B. those C. one D. that

解析：答案為D。it用來代替不可數(shù)名詞或單數(shù)可數(shù)名詞，特指前面提到的“同類同物”；one一般用來替代帶不定冠詞的可數(shù)名詞，表示“同類異物”，泛指同一類中的一個；that 常用來替代帶定冠詞的不可數(shù)名詞或單數(shù)可數(shù)名詞，表示“同類異物”。the one=that；the ones=those， that不能指代人的概念，而those既可以替代人也可以替代物。此處that替代the information。

5. ——There is still a copy of the book in the library. Will you go and borrow ____?

——No, Id rather buy ____ in the bookstore.（陜西）

A. it; one B. one; one C. one; it D. it; it

解析：答案為A。it用來代替不可數(shù)名詞或單數(shù)可數(shù)名詞，特指前面提到的“同類同物”，第一空與a copy of the book指同一物，用it；one一般用來替代帶不定冠詞的可數(shù)名詞，表示“同類異物”，泛指同一類中的一個,第二空符合此點，則用one。
