(单词翻译:单击)

   1. because 表示的是必然的因果关系,语气最强,通常放在主句之后,若需强调则放在主句之前……

  2. 通常用来回答 why提出的问题。如:
  A:Why can't you do it now?你为什么不现在就做呢?
  B:Because I'm too busy. 因为我太忙。
  3. 可引导从句作表语。如:
  It is because he is foolish1. 那是因为他太蠢了。
  4. 可用于强调句。如:
  It is because he is honest that we likehim. 是因为他诚实我们才喜欢他。
  5. not…because…这一结构中的 not 有时否定主句,有时否定从句,一般要根据句子的意思作出正确或合乎逻辑的理解。若not否定主句,最好在because之前用逗号,否则会引起歧义,如下句在没有特定上下文时就有两种解释。如:
  I didn't go because I was afraid.
  (1) 我没有去是因为怕。
  (2) 我不是因为怕才去。
  不过若because之前有just修饰,一般认为not 是否定从句而不是主句。如:
  You shouldn't get angry just because some people speakill of you. 你不要因为有人说你坏话而生气。
  He was not readyto believe something just because Aristotle said so. 他并不只是因为亚里士多德说过如何如何,就轻易相信它。
  6. 表示“…的原因是因为…”这一意义时,一般要用下面这样的句型。如:
  The reason why he can't come is that he is tired. 他不能来是因为他累了。
  在这一结构中尽管不少人认为可将that改用 because, 但也有不少人反对这一用法,学生宜慎用。
  7. 汉语习惯上说“因为…所以…”,但在英语里却不能将 so与because 连用。如:
  因为下雨,所以我们呆在家里。
  正:Because it was raining, we stayed at home.
  正:It was raining, so we stayed at home.
  误:Because it was raining, so we stayed at home.
  8. 用于 because of, 意为“因为”,用法注意:
  (1) 是复合介词,其后可接名词、代词、动名词以及由关系代词型的 what 所引导的从句等。如:
  He couldn't come because of illness. 他因病不能来。
  I said nothing about it, because of his wife'sbeing there. 因为他妻子在那儿,我对此事只字未提。
  He knew shewas crying because of what he had said. 他知道她哭是因为他说的话。
  注意:
  because of不能直接引导从句或后接that引导的从句。如:
  他不能来是因为他病了。
  正:He can't come because he is ill.
  正:He can't come because of his illness.
  误:He can't come because of he is ill.
  误:He can't come because of that he is ill.
  (2) because of 一般引导状语,不引导表语 (引导表语时可用 dueto)。如:
  正:His absence3 is due2 to the rain. 他因雨未来。
  误:His absence is because of the rain.
  但是若主语是代词 (不是名词),because of 引出的短语则可用作表语。如:
  It is just because of money. 那只是因为钱的原因。
  9. 关于 because, since, as, for 的用法区别
  (1) . because 可用来回答why提出的问题;可以引导表语从句;可用于强调句等,而其余三者则不行。
  (2) because 表示的是必然的因果关系,语气最强,通常放在主句之后,若需强调则放在主句之前;since, as所表示的原因是人们已知的,是对已知事实提供理由,而不表示直接原因。它们引导的从句通常放在主句之前,有时也放在主句之后。如:
  As he wasn't ready in time, wewent without him. 因他未及时准备好,我们没等他就先走了。
  Since we have no money, it's no good thinking4 about a holiday. 既然我们没有钱,考虑度假有什么用。
  至于 for, 它是并列连词 (其余三者为从属连词),它有时可表示因果关系 (通常要放在主句之后,且可与 because 换用);有时不表示因果关系,而是对前面分句内容的解释或推断 (也要放在主句之后,但不能与 because 换用)。试比较。
  ①The ground is wet, for (=because) it rained last night. 地面是湿的,因为昨晚下过雨。
  ②It must have rained last night, for the ground is wetthis morning. 昨晚一定下过雨,你看今天早上地面是湿的。
