   英语连词中,because,since,as 和for均有“因为”之意,表示原因,这是它们的共性。但是四个连词也有其个性。四个连词的用法具体如下:


  1. Because:引导直接原因,语气最强。常用来回答why问句。
  ---Why is she late for school? 她为什么上学迟到?
  ---Because she gets ill. 因为她病了。
  2. Since:
  (1)表示显然或已经为人所知的理由,侧重在主句:
  Since we are here now, we should try our best to finish our tasks.
  既然我们到这儿了,我们应该尽全力完成任务。
  (2)引导完成时态,表示“自...以来”:
  Great changes have taken place in this city since I moved here.自从我搬到这里以来,这座城市变化很大。
  3. As:
  (1)与since意义相近,表示显而易见的理由或原因,但语气较since弱。
  As you were out, I left a message. 你不在,所以我留了一张字条。
  (2)随着:
  As the living standard increases, we have more opportunities to enrich 1 our daily life.
  随着生活水平的提高,我们有更多机会来丰富日常生活。
  (3)正如:As we all know, English is very important. 正如我们所知,英语很重要。
  (4)尽管:Children as they are, they know a lot. 尽管他们还是孩子,但是懂得很多。
  (5)按照...方式:Just do as I told you. 按照我说的做。
  4. For: 表示推断或附加的理由,语气最弱。不可用于句首,一般位于主句后,并前面加逗号与主句隔开。
  You had better comfort him, for he is very sad now. 你最好安慰一下他,因为他现在很伤心。
  It must have rained, for the ground was wet. 地面湿了,一定是下过雨了。
  (此处不可用because,因为是从“wet”推测出“rained”,但是也有可能是其他原因。)
  因此,在语气强度上,because--since--as--for,语气依次减弱。另外,前三者属于从属连词,引导的是原因状语从句,而for是并列连词,引导的是并列句。同时,since作为连词,还可以引导完成时态,表示“自...以来”;as为连词时,还有“随着”、“尽管”、“正如”和“按照...方式”等含义。

vt.充实,使丰富,使富裕,使富有
  • Some cream will enrich the sauce.在调味汁里加一些奶油会使其味道更加丰富。
  • Music can enrich your life.音乐能丰富你的生活。
