在英語中,我們常用It is/was(not)… who/that結構來突出強調句子的某一成分(主語,賓語或狀語)。在這個句型中,it沒有詞匯意義,只是引出被強調的成分。如果被強調的成分是表人的詞,用who或that連接都可以。如果是其它成分,則一律用that來連接。如
It is Tom who/that has broken the record. It was in this room that Tom was born.
一、在使用強調句型時須注意的幾個問題:
A) 原句子是現在時或將來時,強調句用It is +被強調的部分 + that (who)…;若原句子是過去時,強調句用:It was +被強調的部分 + that (who)…
(1) Tom will work in China.---It is in China that Tom will work.
(2) I studied at this schooltwo years ago.
—It was at this school that I studied two years ago.
B) 即使被強調部分是復數,It后始終用單數形式。如
Jim and Tom gave us much help.--It was Jim and Tom that gave us much help.
C) 強調人時,可用who/ that,但若強調時間、地點、原因、方式等時,不能用
when, where, why, how,仍用that,如:It is Jim who / that helps us make progress.
It was in front of the bank that the old lady was robbed.
It was because of the heavy rain that he came late.
D)被強調成分是主語,who/that后謂語動詞要在人稱和數上與原句主語一致。
(1) It is I who am right.(2) It is the students who are lovely.
E)被強調成分是作主語的代詞,用主格,是作賓語的代詞,用賓格
It was he that helped me yesterday. It was me that he helped yesterday.
F)疑問句強調:be + it +…that+…? (一般)/特殊疑問詞+be + it that+…?(特殊 ) 如:(1)Was it you who put the book on my desk?(2) What is it that made him so angry?
G)雙賓語強調:無論強調哪個賓語,都必須根據動詞的搭配關系,加上to或for等介詞。如:原句:He gave Mary a pen.
強調直賓:It was Mary that he gave a pen to. 強調間賓:It was a pen that he gave to Mary.
(H)強調結構作賓語時要用陳述句語序。如:I don’t know where it is that he has gone.強調主語時,who或that后面的謂語形式須與被強調的主語保持一致。如:
Lily speaks Chinese very well. —It is Lily that speaks Chinese very well.
(I) 強調句型不用于強調謂語、表語、since, as等引導的原因狀語從句。
二、 not…until結構中時間狀語的強調:It is/was not until+時間狀語+that+… 如:I didn’t go to bed until twelve o’clock last night.
---It was not until twelve o’clock last night that I went to bed.
三、反意疑問句:It was Tom that broke the door, wasn’t it?
四、強調結構的判斷:去掉it is/was和that后,剩余部分(經調整后) 是否依然是個完整的句子,若是,就是強調結構,否則就不是。
It is a pity that you could not come. (不是)
It was at ten that he got home. (是)
