【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(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,科學家開
始了新的技術,在不損害環(huán)境的基礎上增加農(nóng)業(yè)產(chǎn)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(jié)。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(jù)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]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。
