【句型歸納】
【考點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，農民們生產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，科學家開
始了新的技術，在不損害環境的基礎上增加農業產量。
該兩句中的it用于強調句型。
it可以用來改變句子的結構，使句子的某些成分受到強
調。強調的基本句型結構為：It is / was + 被強調部分
+ that + 句子的剩余成分。
強調句型可分別強調主語、賓語、地點狀語、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。杰克送給簡一朵漂亮的紅玫瑰。
注意：
1. 強調人時，that可以換成who。
2. 當被強涮部分較復雜時，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. 強調句型用于疑問句時，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
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] 強調句型。
[答案與解析]B 根據以上的解釋．本句強調主語，又
指物，所以用that。
【考點2】What do you think is the most important thing
in yourjob7你認為在你工作當中最重要的是什么?
該句中賓語從句的引導詞what位于句首，構成一種特
殊句式。在由 do you think / believe / suppose / expect
/ imagine 等詞引導賓語從旬時，需要把賓語從句的引
導鬩位于句首，構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?
你認為他什么時候回到祖國的?
Which team do you think will Wi’ll the World Cup?你認
為哪一個隊將贏得l什界杯?

[考查目標]疑問詞 + do you think / suppose / believe
+賓語從句剩余成分”。
[答案與解析]C 根據以上的解釋，需要填what的謂
語動詞，所以用has happened。
