demand 用法

我們說的 demand sb do sth ,其實是下面第4個用法的簡寫形式。
  demand (that可省略)sb (should可省略) do sth。

  下面附上demand作動詞的用法:
  1. demand + 名詞或代詞
  demand後接名詞或代詞時,其主語可以是人也可以是事(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)
  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)
  2. demand + 動詞不定式
  demand後接動詞不定式時,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過。
  3. demand sth. from / of sb.
  Yesterday evening, the couple came to my house and demanded help from / of me.
  昨天晚上,夫婦倆來到我家要求我幫忙。
  4. demand +從句
  demand後接賓語從句時,從句謂語一般要用虛擬語氣,即"should + 

動詞原形";其被動語態為 "should + be +動詞過去分詞\",其中should可以省略。例如:
  The manager demanded that the workers (should) work extra hours to complete the task ahead of time.
  經理要求工人加班,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。
