(6). Where was it ________ you found the lost child?
A. who B. that C. which D. what
（四）not … until … 句型的强调句 1、句型为：It is/ was not until + 被强调部分 + that + 其它部分 e.g. 普通句：He didn’t go to bed until/ till his wife came back. 强调句：It was not until his wife came back that he went to bed. 2、注意：此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not … 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。
(五)有时也可用It might be…that…; It must have been…that…句型表示强调。如: It might be his father that you’re thinking of. It must be his father that you saw.
二、强调句型的判断
把“It, be，that”去掉，如果剩余部分句子结构仍然完整（被强调部分要还原到原位置），那么这个句子就是强调句；如果句子不完整，则不是强调句。如： （1）①It is he who / that often helps me with my English. ②It is on the hillside that we plant trees every year.
③It was because of bad weather that the football match had to be put off. ④ It was 9 o'clock when we came back． ⑤ It was 3 hours since we had come back．
（2）① It was at the theatre _________ Lincoln was murdered. It was the theatre _________ Lincoln was murdered.
A. which B. that C. where D. the one
② It was our teacher ________did the experiment in the lab last night.
A. whom B. that C. which D. where ③ It was ten years ago________ Miss Gao returned to China. A. that B. when C. since D. as ④ It was ________ he said ______disappointed me.
A. what; that B. that; that C. what; what D. that; what
⑤ It was for this reason ________ her uncle moved out of New York and settled down in
a small village.
A. which B. why C. that D. how
三、强调句型几注意
首先，我们按强调句的语序来总结强调句的五项注意： 1. 句首词用“It”，不能用“This”，“That”等。
2. be动词的形式是is或was，不能用复数形式are或were。 若原句的谓语动词用了现在时或将来时，则用is;若原句的谓语动词用了过去时或过去完成时，则用was.
（1) It ___the Chinese women that___ a great role in the socialist construction. A is; plays B are; play C is; play D are; plays
（2) ___all these exercises____ all of us can do tomorrow.
A. It is; that B. It was; that C They are; which D It will be; that 3. 被强调的部分如果是代词，强调主语用主格，强调宾语用宾格。如： （1）It is him that/who /whom I met in the street yesterday. （2）It is I who/that am wrong.
4. 连接词一般用that，当强调部分是人时，既可用that也可用who.特别注意当强调部分是时间状语或地点状语时，不能用when或where。
Eg: It was on Oct 1st, 1949 that People’s Republic of China was founded. It was at the gate ________ he told me the news.
A. that B. what C. which D. when
5. 主谓一致问题
被强调的主语要和 that后面的谓语动词在数上保持一致。 （1）It is Mary who often_____( help) me with my English. （2）It is I that ____(be)against you.
（3）It is the boy students of Class Two who ___(be)playing football on the playground. （4）It is Mr Green ,together with his wife and children ,that ____in China now. A are B is C was D were (5)It was neither you nor he that___ to blame for the mistake. 6.not… until 结构的强调：
强调“not…until”引导的时间状语时，要用“it is/was not until…that…”结构,，that后面的句子要用肯定式，且须用陈述句语序。
Eg: 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)
(1)It was not until 1920___ regular radio broadcast began. A. while B. which C. that D. since
(2)It was not ____ she took off her dark glasses ____ I realized she was a famous film star. A. when; that B. until; that C .until; when D. when; then (3) It was ________ back home after the experiment.
A. not until midnight did he go B. until midnight that he didn't go
C. not until midnight that he went D. until midnight when he didn't go （4）It was not until ________ that ________ to prepare his lessons.
A. did his father come in; the boy began B. his father came in; the boy began
C. did his father come in; did the boy begin D. his father came in did the boy begin 7.强调时间状语和地点状语时与定语从句的区别： (1 ) It was on the farm that we practised planting crops. It was the farm where we learned a lot .
(2) It was at the street corner that I met Lucy yesterday. It was the street corner where I met Lucy yesterday. (3) Was it in this palace ________ the last emperor died?
A. that B. in which C. in where D. which 8. 强调句型与主语从句的区别：
强调句型可以还原成正常语序的句子，也就是说，强调句型中去掉It be… that后，句子仍然通顺，意义也依然完整，只是没有那么强调突出。而含主语从句的复合句中的it是指
示代词，后面多为系表结构或被动语态。如果去掉It be…that，句子就不通顺了。如： It is certain that he is honest and modest.
It is known to all that paper was made first in China.
