【句型歸納】
【考點(diǎn)l】It is on this arable land that the farmers produce
food for the whole population of China. 就在這些耕地
上，農(nóng)民們生產(chǎn)了供給全中國人口的糧食。
It was from the early 1990s that scientists started to de-
velop new techniques to increase agricultural production
without harming the environment. 90年代初，科學(xué)家開
始了新的技術(shù)，在不損害環(huán)境的基礎(chǔ)上增加農(nóng)業(yè)產(chǎn)量。
該兩句中的it用于強(qiáng)調(diào)句型。
it可以用來改變句子的結(jié)構(gòu)，使句子的某些成分受到強(qiáng)
調(diào)。強(qiáng)調(diào)的基本句型結(jié)構(gòu)為：It is / was + 被強(qiáng)調(diào)部分
+ that + 句子的剩余成分。
強(qiáng)調(diào)句型可分別強(qiáng)調(diào)主語、賓語、地點(diǎn)狀語、時間狀語
等。例如：
It was at Christmas that Jack gave Jane a beautiful red
rose. 就是在圣誕節(jié)。杰克送給簡一朵漂亮的紅玫瑰。
注意：
1. 強(qiáng)調(diào)人時，that可以換成who。
2. 當(dāng)被強(qiáng)涮部分較復(fù)雜時，特別記住不能漏寫了that。
例如：
It was not until he came back at midnight that I left.
直到他半夜回來，我才離開。
3. 強(qiáng)調(diào)句型用于疑問句時，注意語序。例如：
When and where was it that Liu xiang broke the
Olympic record? 到底在何時何地。劉翔打破了奧運(yùn)
會記錄呢?
【考例】】(2003上海) It is these poisonous products
____ can cause the symptoms of the flue, such as
headache and aching muscles.
A. who B. that
C. how D. what
[考查目標(biāo)] 強(qiáng)調(diào)句型。
[答案與解析]B 根據(jù)以上的解釋．本句強(qiáng)調(diào)主語，又
指物，所以用that。
【考點(diǎn)2】What do you think is the most important thing
in yourjob7你認(rèn)為在你工作當(dāng)中最重要的是什么?
該句中賓語從句的引導(dǎo)詞what位于句首，構(gòu)成一種特
殊句式。在由 do you think / believe / suppose / expect
/ imagine 等詞引導(dǎo)賓語從旬時，需要把賓語從句的引
導(dǎo)鬩位于句首，構(gòu)成一種特殊的疑問句“疑問詞 + do
you think / believe / suppose / expect / imagine + 賓語
從句剩余成分”。例如：
When do you suppose he came back to his motherland?
你認(rèn)為他什么時候回到祖國的?
Which team do you think will Wi’ll the World Cup?你認(rèn)
為哪一個隊(duì)將贏得l什界杯?
【考例2】(NMET】991)
-- We haven't heard from Jane for a long time．
-- What do you suppose ____ to her?
A. was happening B. to happen
C. has happened D. having happened
[考查目標(biāo)]疑問詞 + do you think / suppose / believe
+賓語從句剩余成分”。
[答案與解析]C 根據(jù)以上的解釋，需要填what的謂
語動詞，所以用has happened。
