2013考研英语复习语法要点:原因状语

3.原因状语
  原因状语从句三个最常用的连词是because, since, as,其中because语气最强,since次
  之,as最弱。
  1) because从句通常是直接回答why问句的,这时不能用since, as或for。例如:
      Why don't you call on me tomorrow?
      Because I have an important meeting to attend.
      由because引导的从句通常里于主句之后,也可置于主句之前。我们需要区分because
      与for的用法=for是并列连词,because是从属连词,because总是表示因果关系,而
      for则有时表示因果关系,有时不表示因果关系。当for表示因果关系时,它可以和be-
      cause交替使用。例如:
      He could not have seen me, for/because I was not there.
      他不可能看见过我,因为我不在那儿。
      She was not helpless,for/because she had money of her own.
      她不会孤立无援,因为她有钱。
      这里fo:均可由because所代替,所不同的是because从句的位置可前可后,而for从
      句只能后It.当for从句不表示因果关系,而只是对前面的分句的内容加以解释时,
      for不能为because所替换。例如:
  It rained last night,for the ground is wet this morning.
  这里for不能为because所替换,因为现在地湿并不是造成昨天下雨的原因,而是昨
  天下雨的结果。我们将它改为:
  The ground is wet,for/because it rained last night.
  同样,下列各句都只能用for,不能用because.
  It will rain,for the barometer is falling.
  The day is going to dawn,for the birds are singing.
2)由as和since引导的原因状语从句
  as和since引导的原因状语从句差别不大,其侧重点落在主句上,原因只是附带说明。
  例如:
  As/Since he was not at home,I spoke to his brother.
  由as/since引导的原因状语从句通常位于主句之前,但有时也可置于主句之后,由
  since表示的原因,指的是人们已知的事实,愈为“既然”。
  Since you are as sure of it,he'll believe you.
  既然你对此这么有把握,他会相信你的。
  Since the speaker can't come,we may as well cancel the meeting.
  既然演讲者不能来,我们倒不如取消这次会议。
Since the weather is so bad outside,why don't you stay with us overnight?
既然外面夭气这么恶劣,为什么不和我们呆上一晚上呢?
注意,在强调句it is…that中,只能用because从句,不能用since, as。同时,表示并

  列关系的连词,如whereas, while, for也不能用在强调句it is... that。二结构中。
  It was because he was ill that he didn't go with us.(正)
    ,It was since/as/whereas/while he was ill that he didn't go with us.(误)
3)由其他连词或词组引导的原因状语从句,considering (that)(考虑到), in that(因
  为),now (that)(既然),seeing (that)(鉴于),…allowing for...等.例如:
  In that he did not come to work yesterday, it showed that he is not very interested
      in it.
  因为他昨天没有来工作,这就表明他对此不感兴趣。
  The speech is all the more important in that it was made by a man of authority.
  这次演讲是由一位权威人士作的,所以尤其重要。
  Now that you have finished the work,you are free to do what you like.
    既然已经完成了工作,你就可以随心所欲地干点什么。
  Seeing that it is eight o'clock,well wait no longer.
    由于时间已到8点,我们便不再等待.
  Seeing that all the guests have arrived,let's have dinner.
    客人都到了,我们开始晚宴吧。
  Considering that he began learning English only a year ago,he speaks very well.
  考虑到他一年前才开始学英语,他算是讲得很好了。
  Considering that his wife had just recovered from a bad cold, he decided not to take
  her to the party.
  考虑到他妾子刚刚从重感,中恢复,他决定不带她去参加舞会。
  Allowing for the train being late,we should be back by eleven.
  把火车误点考虑在内,U点之前我们应该可以回家。
4)介词词组+that
  On the grounds that,for the reason that,on account of the fact that,owing to the
  fact that,due to the fact that, in view of the fact等。
  She is suing for divorce on the grounds that he is a drunkard.
  她起诉提出离婚,理由是他是个酒鬼。
  He cannot be dismissed for the simple reason that he didn't attend yesterday's meet-
  ing.
  不能仅仅因为他未参加昨夭的会就将他解雇。
  On account of the fact that all the trains were delayed,the station was crowded with
  people.
  因为所有列车都推迟了,火车站塞满了人。
  We had to anchor in view of the fact the tide ran against us.
  我们不得不抛锚,因为我们碰上了潮水。
5)在not that ... but that结构中,that = because,即not because ... but because.例
    如:
  I haven't finished writing the report yet, not that I dislike the work, but that I have
    no time.
  我还没有写完这份报告,不是因为我不喜欢这份工作,而是因为我没有时间。
  He always traveled third-class,not that he was so miserly, but that he wanted to go
  side by side with ordinary people.
  他旅游时坐的是三等舱,不是因为如此吝贵,而是因为他想与普通人打成一片.
6)名词短语表示原因状语,例如:
  An extremely selfish person, Peter never cared for other people's interests.
  或Extremely selfish,Peter never cared for other people's interests.
  或Being an extremely selfish person, Peter never cared for other people's interests.
  彼得是个极端自私的人,从不关心别人的利益.
