高中英語 語法精講（Unit 19 Modern agriculture）人教版
語法精講The Use of “It” (2) for Emphasis “It”的用法(2)表示強調
強調結構：It is/was+被強調部分+that/who+句子剩余部分。強調結構可用來強調除謂語之外的所有成分：主語、賓語、狀語等。應注意以下方面：
1.強調主語用主格，強調賓語用賓格。
It was I that met Tom in the park.
It was him that I met in the park.
2.只有強調人的時候可用who,其余的一律用that,不管強調的是時間、地點還是原因、方式。
It was in Shanghai that I saw the film.
3.若把強調結構中的“It is/was...that/who...”去掉，仍為一個完整句子，因此應注意狀語的完整性，一定不要丟掉了必要的介詞。
It was in 1975 that I worked in the factory.
4.若強調主語，從句的謂語動詞應與被強調的主語一致。
It is Prof.Lin who teaches us English.
5.注意強調結構與定語從句的區別。
It is the factory where I worked 30 years ago.(定語從句)
It is in the factory that I worked 30 years ago.(強調結構)
6.注意not...until的強調：把not與until一并提前。
It was not until his mother came back that he went to bed.
7.注意強調結構的疑問形式。
Was it in the room that we held a meeting?
When was it that you saw him for the first time?

A.that
B.when
C.since

答案:A
【考例2】(2006全國高考Ⅱ,9)It was not until she got home _________ Jennifer realized she had lost her keys.
A.when
B.that
C.where
D.before
解析:強調句的基本結構為“It is/was+被強調部分+that/who...”。本題強調時間狀語從句，用that。
答案:B
【考例3】(2006山東高考，32)I just wonder ________ that makes him so excited.
A.why it does
B.what he does
C.how it is
