It 引導(dǎo)的強(qiáng)調(diào)句型結(jié)構(gòu)為：“It +be 動(dòng)詞的一定形式 +被強(qiáng)調(diào)部分 + that /who 從句 ”。這一結(jié)構(gòu)是高考常見(jiàn)句型之一。 現(xiàn)將常見(jiàn)考點(diǎn)分析如下：

一． 考查引導(dǎo)詞it和強(qiáng)調(diào)人稱(chēng)代詞的情況。在該句型中it是固定用法，一般不可用其他詞來(lái)替換。人稱(chēng)代詞是主語(yǔ)時(shí)用主格，是賓語(yǔ)時(shí)用賓格。例如:Was____that I saw last night at the concert? A. it you B. not you C. you D. that yourself Key: A (MET95’上 海)

二． 考查引導(dǎo)從句的引導(dǎo)詞。注意被強(qiáng)調(diào)部分除指人時(shí)均可用that/who外，其他均可用that，即使強(qiáng)調(diào)的是時(shí)間，地點(diǎn)或原因狀語(yǔ)時(shí)，也不可用when, where或why。

例如 ：（1）.Was it during the Second World War____he died ? A. that B. while C. in which D. then Key : A (MET’88)

(2).It was about 600 years ago____the first clock with a face and an hour hand was made. A .that B. until C. before D. when Key : A (MET’97)

(4).It was at the gate____he told me the news. A. that B. what C. which D. when Key: A (MET’80)

(5)._____was in 1997_____I graduated from the university. A. That , that B. It ,that C. That , when D. It , when Key : B (MET’98 上海)

(6).Was it in 1969_____the American astronaut succeeded____landing on the moon? A. when , on B. that , on C. when , in D. that , in Key: D (MET’94 上海)

三． 考查強(qiáng)調(diào)狀語(yǔ)時(shí)的兩種特殊情況：

1).強(qiáng)調(diào)由not---until引導(dǎo)的狀語(yǔ)或狀語(yǔ)從句時(shí)，要把not與until放在一起。

例如：(1).It was not____she took off her dark glasses____I realized she was a famous film star. A. when , that B. until , that C. until , when D .when , then Key: B (MET’92)

(2).It was not until 1920____regular radio broadcasts began. A. while B. which C. that D. since Key: C (MET’95)

2).強(qiáng)調(diào)原因狀語(yǔ)從句時(shí)，該從句必須是because引導(dǎo)的原因狀語(yǔ)從句，因?yàn)橹挥衎ecause表示的語(yǔ)氣最強(qiáng)。例如：（1）It was because he was ill that he didn’t go to school yesterday. (2).It is___it is raining hard that they can’t go out for an outing. A. as B. since C. for D.because Key: D

四． 考查強(qiáng)調(diào)部分為特殊疑問(wèn)句的結(jié)構(gòu)，要把特殊疑問(wèn)詞放在句首，其后接一般疑問(wèn)句語(yǔ)序。其結(jié)構(gòu)是：疑問(wèn)詞+is/was+it+that+其他部分。這類(lèi)句型如出現(xiàn)在賓語(yǔ)從句中，其結(jié)構(gòu)為：疑問(wèn)詞+it+is/was+that+其他部分。

例如：（1）.Where was it that you met the Frenchman?

(2). What is it that makes man different from other animals?

(3).I really don’t know when it is that she is to arrive in Shanghai.

(4).I can’t quite remember when it was that you started doing the work.

五． 考查強(qiáng)調(diào)句型后面加上附加疑問(wèn)句時(shí)，主語(yǔ)要用it，而不能用原來(lái)的主語(yǔ)。

例如：It was John and Mike that you saw in the park yesterday, wasn’t it ？

六． 考查強(qiáng)調(diào)句型的問(wèn)句回答語(yǔ)時(shí)，肯定用Yes,it is/was.否定用 No,it isn’t/wasn’t. Be動(dòng)詞還可以用復(fù)雜形式：情態(tài)動(dòng)詞+完成形式。

例如：（1）A: Was it the headmaster who walked by ?

B:It must have been.

(2) __Wasn’t it Dr Wang who spoke to you just now ?

__ _______________.

A.No, he didn’t B. No, he wasn’t C. Yes, he did D. Yes, it was Key: D (MET’96 上海)

七．考查被強(qiáng)調(diào)部分是主語(yǔ)或主語(yǔ)從句的情況。當(dāng)被強(qiáng)調(diào)的部分是主語(yǔ)時(shí)，who/that引導(dǎo)的從句的謂語(yǔ)應(yīng)該與被強(qiáng)調(diào)部分在人稱(chēng)和數(shù)上保持一致。

例如：(1).It is I who am in charge of the factory.

(2).It was they who were making the same mistakes.

(3).Is was___he said____disappointed me.
