高考英語第一輪單元基礎知識復習
如：it was my telephone number that miss white happened to know.懷特小姐碰巧知道到的就是我的電話號碼
（3）對“—not---until---“這一結構進行強調時，一般使用”it is/was not until---that---“
這一句型進行強調。如：
i didn’t go home until the rain stopped.直到雨停了我才回家
強調句為：it was not until the rain stopped that i went home.
(4)被強調的部分是人稱代詞，如其在原句中作主語，則應該用該人稱代詞的主格形式；如果作賓語，則用其賓格形式
it was she(her) who told the police.就是她報告警察的
it was you who we were talking about.
(5)強調句的一般疑問句句型： is/was+it+that/who/whom----?
was it ten years ago that his father died?
(6)強調句的特殊疑問句型：疑問詞+is/was+it+that/who/whom----?
when is it that you will set off?你到底什么時候出發？
【點撥】
a.強調句型的結構不難掌握，要想準確使用它，須明確一點：去掉it is/was---that---結構不會對句子的完整性造成影響，這是區分它與其他句子的一個重要標志
it was i who advised him not to do it.
去掉后：
i advised him not to do it.(完整句)
b. 強調句型容易與主語從句、狀語從句、同位語從句和定語從句混淆
it is quite clear that we need more practice.很顯然，我們需要多實踐
此句看上去像是強調句型的句子，而實際上，它是主語從句。it在句中充當形式主語，真正的主語為that所引導的從句。判斷的理由為去掉it be---that結構后，原句不完整。再如：
it was at about 12 o’clock that the fire was put out.大火在大約12點被撲滅了。（強調句型）
it was about 12 o’clock when the fire was put out. 撲滅大火的時候大約在12點（定語從句）
