Get students to do the exercises in the workbook to put the structures and vocabulary into practical use and then check their answers. And explain some difficult and important points to students. Step 4 Summary of Emphatic Structures A. 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.(Shanghai 2003, spring)
分析：去掉It is / was... that / who 句子后结构仍然完整，句意仍明确，都是强调句。
④ It was 9 o'clock when we came back． 我们回来时是九点钟。
⑤ It was 3 hours since we had come back．我们回来已三个小时了。 分析： 在上面例句中若去掉It was... when / before / since等后，句子结构就不完整，所以不是强调句。 B. 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.
e.g. It ___ he Chinese women that ___ a great role in the socialist construction. A is; plays B are; play C is; play D are; plays ___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。 e.g. It is him that/who /whom I met in the street yesterday. 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。 e.g. It was on Oct 1st, 1949 that People?s Republic of China was founded. It was at the gate ________ he told me the news.(MET'88) 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。 Practice:
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) It was not until 1920___ regular radio broadcast began. (NMET95) A. while B. which C. that D. since
7) It was not ____ she took off her dark glasses ____ I realized she was a famous film star. [1992] A. when; that B. until; that C .until; when D. when; then
8) It was ________ back home after the experiment.

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
(10)Not until____ _____ to prepare his lessons. 注意: (10)是not…until 的另一种强调形式。
e.g. The villagers didn?t realize how serious the pollution was until all the fish died in the river .
It was not until all the fish died in the river that the villagers realized how serious the pollution was.
Not until all the fish died in the river did the villagers realize how serious the pollution was
7. 疑问句的强调结构：
一般疑问句：Is / Was + it +被强调部分+ that +句子的其他部分（陈述语序）。简单的答语为：“Yes, it is/was.”或 “No, it isn?t/wasn?t.” Practice:
(1) ----Was ____ that I saw last night at the concert? (Shanghai '97) ----No, it wasn?t.
A. it you B. not you C. you D. that yourself (2) ----\ it Dr Wang who spoke to you just now? -----_______. (Shanghai '96)
A. I didn't know he was. B. Yes, it was. C. No, he wasn't. D. Yes, he did.
(3)Was it in 1969 ________ the American astronaut succeeded ________ landing on the moon? (Shanghai '95)
A. when; on B. that; on C. when; in D. that; in 8.特殊疑问句：
特殊疑问词+ is / was + it +被强调部分+that +句子的其他部分（陈述语序）。
e.g. Where did you see her cellphone yesterday ? Where was it that you saw her cellphone yesterday?（强调特殊疑问词where） How will you go to visit her tomorrow?
28
How is it that you will go to visit her tomorrow? （强调特殊疑问词how） 9.从句的强调：
e.g. 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) （注意：被强调的原因状语从句只能用because引导，不能用as或since引导)

It was the farm where we learned a lot.

It was the street corner where I met Lucy yesterday
Was it in this palace ________ the last emperor died? (MET88) A. that B. in which C. in where D. which C.谓语的强调
do(does/did)引出强调句 1.在谓语动词之前（通常是现在时和过去时的句子，可用助动词do(does/did) 来强调动词,这时谓语动词须用原形动词。do(does/did)可译成“确实”“的确”。 e.g. To my great joy, the plant did look exactly like what we were looking for. He does work hard and finish the job in time. 2.在肯定的祈使句中，用动词do来加强语气，可译成“务必，一定，千万” e.g. Do come and see us some day. Do give her my regards.
D. 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。 e.g. We did not get off the bus until it stopped . It was not until it stopped that we got off the bus.
