在课堂教学中，许多英语教师都按照下面的句型去施教。即：It is / was …that /who…用来强调一个句子中除谓语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. (强调主语)
It was this car that I bought in that shop last month.(强调宾语)
It was in that shop that I bought this car last month.(强调地点状语)
It was last month that I bought this car in that shop.(强调时间状语)
就这样，再举几个例子，让学生练练，该语法讲解到此结束。可是，高考并不单纯考查这样一些基本的句式，下面几点还有待于老师去延伸讲解。
1． 一般疑问句的强调：
（1） Did you meet your brother at Mc Donald ?
Was it your brother that you met at Mc Donald?(强调宾语)
（2） Has Tom borrowed your money recently?
Is it Tom that has borrowed your money recently? (强调主语)
2 . 特殊疑问句的强调：
(1) Where did you see her cellphone yesterday ?
Where was it that you saw her cellphone yesterday?（强调特殊疑问词where）
(2) How will you go to visit her tomorrow?
How is it that you will go to visit her tomorrow?
（强调特殊疑问词how）
3.从句的强调：
（1）I came home late because it was raining hard.
It was because it was raining hard that I came home late.(强调状语从句)
(2) What you said really made us sad.
It was what you said that really made us sad.(强调主语从句)
4.not until 结构的强调：
We did not get off the bus until it stopped .
It was not until it stopped that we got off the bus.(注意：强调该结构时not until不能分开)
5.强调时间状语和地点状语时与定语从句的区别：
（1） It was in 1921 that our Party was founded.(强调句式)
（2） It was 1921 when our Party was founded.(定语从句)
即：强调时间或地点时有介词置于其前时，则连接词用that。其前面应有介词而被省去时，则用连接词when（时间）或where(地点)。又如：
(3) It was on the farm that we practised planting crops.
(4) It was the farm where we learned a lot .
但是应注意，有些表示时间或地点的词汇及短语本身不需要在其前面加介词，故其连词也只能是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.
由此看来，教师不能只着眼句型教学，该延
伸时必须从多处着手。只有这样，我们所叫的学生才能把知识运用自如。
