在課堂教學中，許多英語教師都按照下面的句型去施教。即：It is / was …that /who…用來強調一個句子中除謂語以外的任何句子成分。例如：
I bought this car in that shop last month.(原始句)
It was I who/that bought this car in that shop last month. (強調主語)
It was this car that I bought in that shop last month.(強調賓語)
It was in that shop that I bought this car last month.(強調地點狀語)
It was last month that I bought this car in that shop.(強調時間狀語)
就這樣，再舉幾個例子，讓學生練練，該語法講解到此結束�？墒牵呖疾⒉粏渭兛疾檫@樣一些基本的句式，下面幾點還有待于老師去延伸講解。
1． 一般疑問句的強調：
（1） Did you meet your brother at Mc Donald ?
Was it your brother that you met at Mc Donald?(強調賓語)
（2） Has Tom borrowed your money recently?
Is it Tom that has borrowed your money recently? (強調主語)
2 . 特殊疑問句的強調：
(1) Where did you see her cellphone yesterday ?
Where was it that you saw her cellphone yesterday?（強調特殊疑問詞where）
(2) How will you go to visit her tomorrow?
How is it that you will go to visit her tomorrow?
（強調特殊疑問詞how）
3.從句的強調：
（1）I came home late because it was raining hard.
It was because it was raining hard that I came home late.(強調狀語從句)
(2) What you said really made us sad.
It was what you said that really made us sad.(強調主語從句)
4.not until 結構的強調：
We did not get off the bus until it stopped .
It was not until it stopped that we got off the bus.(注意：強調該結構時not until不能分開)
5.強調時間狀語和地點狀語時與定語從句的區(qū)別：
（1） It was in 1921 that our Party was founded.(強調句式)
（2） It was 1921 when our Party was founded.(定語從句)
即：強調時間或地點時有介詞置于其前時，則連接詞用that。其前面應有介詞而被省去時，則用連接詞when（時間）或where(地點)。又如：
(3) It was on the farm that we practised planting crops.
(4) It was the farm where we learned a lot .
但是應注意，有些表示時間或地點的詞匯及短語本身不需要在其前面加介詞，故其連詞也只能是that,而不是when或where。再如：
(5) It was yesterday that we chatted a lot on line.
(6) It was there that Mike was drowned yesterday.
由此看來，教師不能只著眼句型教學，該延
伸時必須從多處著手。只有這樣，我們所叫的學生才能把知識運用自如。
