◆ 原句再现
◆ 强调句型的基本结构
It is/was + 被强调部分 + that/who (m)+句子其它成分
※ 让我轻轻地告诉您:强调句型可强调的句子成分通常为主语、宾语、地点状语、时间状语等,也可以强调一个从句。但不能用来强调谓语动词,请观察以下句子
原句:I met my old friend in the park yesterday.
It was in the park that I met my old friend yesterday.(强调地点状语)
It was yesterday that I met my old friend in the park.(强调时间状语)
It was my old friend that I met in the park yesterday.(强调宾语)
It was I who/that met my old friend in the park yesterday.(强调主语)
a. It was in the park that we met the foreigner this morning.
b. It is our teachers that/who often help us.
◆在强调句型中,如果被强调的部分指人时,可用 who(m)/that, 其它一律用 that, 请观察以下句子
◆在强调结构中,无论被强调的是人还是物,是单数还是复数, be 动词一律用 is/was,如果原句的谓语动词是一般过去时态,用was.如果原句的谓语动词是一般现在时,则用 is. 有时也可以用“情态动词 + be”形式, 请观察以下句子
a. It is Tom who/that wins the first prize in the exam.
b. It was the workers who/that built the building three years ago.
c. It might be yesterday that Alice cleaned the classroom.
d. It will be the teacher who go with you tomorrow.
◆强调句型的各种句式变化
a. It is my father that/who is cleaning the floor.
b. It was his teacher that/who helped him yesterday.
●肯定句: It is/was + 被强调部分 + that/who (m)+句子其它成分, 请观察以下句子
●否定句: It is/was not + 被强调部分 + that/who + 句子的其它成分,请观察以下句子
a. It is not Mary that/who is playing basketball.
b. It was not Alice that/who did it last week.
● 疑问句: Is/Was it…that/who + 句子其它成分 + ,请观察以下句子
a. It was last year that the building was completed.

b. It is Zhang Ling that/who is helping the teacher.
→ Is it Zhang Ling that/who is helping the teacher
a. It was by bike that he went school.
→ How was it that he went to school
b. It was on the playground that I came across my English
teacher.

● 特殊疑问句:特殊疑问词 + is/was + it + that + 句子其余部分!特殊疑问句是对陈述句中被强调部分划线提问
变来的,请观察以下句子
◆ not…until…结构可用在强调句型中,其结构为:
It is/was not until …that….(句子其它成分), 请观察以下句子
原句:He didn’t came in until the class began.
→It was not until the class began that he came in.
原句:He didn’t finished doing his homework.
→It was not until last Friday that he finished reading the
book.
◆当强调主语时,谓语动词应和被强调的人或物在人称和数上保持一致。如果被强调的主语是人,人称代词一般用主格,请观察以下句子
a. It is I who/that am going to attend the meeting.
b. It is my teacher who/that helps me with my studies.
c. It is the girls that/who usually dance on the playground.
a. It was a lovely cat that could look after the baby.(定语从句)
b. It was in the garden that Tom grew some flowers. (强调句型)

(时间状语从句)
d. It was at seven o’clock that she saw the injured dog.
(强调句型)
e. It is a pity that they didn’t come to see you yesterday.
(主语从句)
◆强调句型与定语从句、主语从句和状语从句的区别:
一般说来,如果把句子中的 It is/was 和 that 去掉,稍
加调整语序,能还原句子,且句子意思依然完整,则为强调句型;否则,应为其他句式,请观察以下句子
◆考点训练及解析
1. It was _______ it was raining heavily that they had to stay at home
all day. A. because B. since C. for D. since
答案 A. 强调句型只可以强调由 because 引导的原因状语从句,as
/since/for 引导的句子不能用在强调句中。
2. He forgets ______ he saw the film.
A. that it was when B. when it was that 
C. when was it that D. that was it when
答案 B. 分析:假设原句为:
He saw the film when he was three years old.
对时间状语进行强调后为:
It was when he was three years old that he saw the
film.
再对被强调部分 when he was three years old 提问
变成特殊疑问句:
When was it that he saw the film
再让特殊疑问句作宾语从句后, 疑问语序就变成陈
述语序:
He forgets when it was that he saw the film.
3. It was the training ______ he had as a young man ______ made him
such a good engineer.
A. what;that B. that;what
C. that;which D. which;that
答案 D.本句强调主语 the training,而主语后又接 which 引导的定
语从句,还原后应为:
The training which he had as a young man made him a good
engineer.
4. It was _____ he said and something he did ______ disappointed me
at that time.
A. what;that;that B.that;what;that  
C. what;what;that D.what;that;what
答案 A. 此题的强调部分是 what 引导的主语从句和 something ,
而 something 后带有 that 引导的定语从句。
5. Was it through the teacher ____ you came to realize the importance
of learning English
A. who B. whom C. how D. that
答案为 D.强调介词短语 through the teacher,而不是名词 teacher.
选项A、B项具有很强的迷惑性
6. It is the young man ____ looked for _____ caught the murderer.
A. that; who B. that; they C. they; that D. they; which
答案为C.考查了定语从句和强调句型。they looked for前省略了关系
代词 that,that 引导定语从句,同时又在从句中做宾语,可以省略
,如果去掉定语从句,强调句为:
It is the young man who/that caught the murderer.
本句意思是:是他们在寻找的那个年轻人抓住了杀人犯
7. Was it seven o'clock ___ you finished your task
A. when B. that C. then D. which
答案 A. 此题是含有when引导的时间状语从句,不是强调
句型。
8. She told us that it was a small mountain village _______
she lived with her grandparents.
A. that B. which C. where D. when
答案 C. where 引导定语从句,同时又在从句中作状语。
That’s all for today!
