高一英語(yǔ):知識(shí)點(diǎn)總結(jié)Unit19-20(15)

2016-11-27 08:17:39 來(lái)源:高考網(wǎng)

   【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(guó)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(kāi)

  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(lái)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(yǔ)、賓語(yǔ)、地點(diǎn)狀語(yǔ)、時(shí)間狀語(yǔ)

  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(jiǎn)一朵漂亮的紅玫瑰。

  注意:

  1. 強(qiáng)調(diào)人時(shí),that可以換成who。

  2. 當(dāng)被強(qiáng)涮部分較復(fù)雜時(shí),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(lái),我才離開(kāi)。

  3. 強(qiáng)調(diào)句型用于疑問(wèn)句時(shí),注意語(yǔ)序。例如:

  When and where was it that Liu xiang broke the

  Olympic record? 到底在何時(shí)何地。劉翔打破了奧運(yùn)

  會(huì)記錄呢?

  【考例】】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(yǔ),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(yǔ)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(yǔ)從旬時(shí),需要把賓語(yǔ)從句的引

  導(dǎo)鬩位于句首,構(gòu)成一種特殊的疑問(wèn)句“疑問(wèn)詞 + do

  you think / believe / suppose / expect / imagine + 賓語(yǔ)

  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(shí)候回到祖國(guó)的?

  Which team do you think will Wi’ll the World Cup?你認(rèn)

  為哪一個(gè)隊(duì)將贏得l什界杯?

  【考例2】

  -- 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(wèn)詞 + do you think / suppose / believe

  +賓語(yǔ)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(yǔ)動(dòng)詞,所以用has happened。
