demand的用法

  領悟歸納一:

  demand是第14單元的重點詞匯,也是高考考查的熱點之一。為幫忙同學們?nèi)嬲莆蘸挽`活使用這一詞,現(xiàn)將其用法歸納如下:

  一、demand作動詞用

  1.demand + 動詞不定式

  demand后接動詞不定式時,主語通常是人而不是物;動詞不定式可根據(jù)需要用主動或被動形式。例如:

  She demanded to be told everything about it. 她要求知道事情的整個經(jīng)過。

  2.demand + 名詞或代詞

  demand后接名詞或代詞時,其主語能夠是人也能夠是事(物)。一般來說,當人作主語時,表示主觀要求;而事(物)作主語時則表示客觀需要。例如:

  The foreign customer demanded an apology from the saleswoman in the supermarket.這位外國顧客要求超市女售貨員向其道歉。(主觀要求)

  The gatekeeper demanded my name and address. 門衛(wèi)要求我說出姓名和地址。(同上)

  As is known, fishing is a job that demands great patience. 眾所周知,釣魚是一項需要耐性的工作。(客觀需要)

  Does this letter demand an immediate reply? 這封信需要立即答復嗎? (同上)

  3. demand sth. from / of sb.

  Yesterday evening, the couple came to my house and demanded help from / of me. 昨日晚上,夫婦倆來到我家要求我?guī)兔Α?/p>

  What do you demand from /of me? 你們要我做什么?

  4. demand +從句

  demand后接賓語從句時,從句謂語一般要用虛擬語氣,即"should + 動詞原形";其被動語態(tài)為 "should + be +動詞過去分詞",其中should能夠省略。例如:

  The manager demanded that the workers (should) work extra hours to plete the task ahead of time. 經(jīng)理要求工人加班,以提前完成任務。

  All the settlers nearby demanded that the nightclub (should) be moved away as soon as possible. 附近所有居民都要求那家夜總會盡早搬走。

  二、demand作名詞用

  demand用作名詞時既可用作可數(shù)名詞,也可用作不可數(shù)名詞。常見用法有:

  1. 表示"要求;要求的事物"。例如:

  The workers' demands for higher pay and better working condition were turned down.工人們加薪和改善工作條件的要求遭到拒絕。

  There have been demands for the prime minister to resign. 已有許多人要求首相辭職。

  2. 表示社會對于人才、貨物的需要。例如:

  A few years ago, there was high demand for typists. 幾年前(社會上)極需打字員。

  I'm afraid that the supply of this product can hardly meet the demand. 恐怕這種產(chǎn)品可能會供不應求。

  I'm sorry, but there is little demand for these goods at present. 實在抱歉,但是此刻這些貨物的需求量極小。

  領悟歸納二:

  demand可用為demand to do sth.或demand + that從句,但要注意demand 后接that從句時,從句的謂語形式要用虛(should) + v.的虛擬語氣形式,切記不可用demand sb. to do sth.

  領悟歸納三:

  demand的意思、解釋

  過去式:demanded; 過去分詞:demanded; 此刻分詞:demanding; 復數(shù)形式:demands;

  vt.

  1. 強烈要求

  2. 需要

  n.

  1. (顧客的)需求、需要

  2. (堅決的)要求, 所需求之物

  3. (尤指困難、使人勞累、令人煩惱等的)要求

  demand的用法例句

  1. He's quite within his rights to demand an enquiry.

  他完全有權要求進行調(diào)查。

  2. Soft drinks are much in demand this hot weather.

  3. Your allegations are pletely untrue, and I demand an immediate apology.

  4. If Johnson has any self-respect, he will demand the demotion of police officers who decided to act as a law unto themselves.

  如果約翰遜有些自尊的話,他就會要求把那些準備不顧法規(guī)而自行其是的警官們降職。
