  ◆ because/since/as/for

  ◇ 这四个词都是表示原因或理由的连接词,但是as,because,since是从属连词,引导原因状语从句,for是并列连词,所引导的不是原因状语从句,而是表示理由的对等句子,是对前面所讲内容补充和说明。在语气上由强至弱依次为because→since→as→for。because引导的从句多置于句末,表示直接的原因或理由,表示产生那种结果的必然的因果关系,在回答why的提问时,必须用because作答。

  如:We stayed at home because it rained.因为下雨我们呆在家里。

  ◇ as与since引导的从句多置于句首,不过as表示十分明显的原因,只说明一般的因果关系,可译为“因为、由于”;而since则表示稍加分析、对方已知的原因,一般可译为“既然”。如:

  As he was not feeling well,I decided to go there alone.由于他身体欠佳,我决定独自去那里。

  Since everyone is here,let's start.既然大家都到了,咱们就开始吧。

  ◇ for引导的从句一般放在句末,其前用逗号,它所叙述的理由是间接的,即推测性理由,或是对前面叙述的事实或看法的补充说明。如:

  There must be nobody in the classroom,for the light is off.

  教室里一定没有人,因为灯灭了。(推测性理由)

  ◆ believe;believe in

  ◇ believe作及物动词时,其后可跟名词,表示“相信”;后接从句或复合宾语时,表示“认为;料想;相信”等。如:

  I believe what he says.我相信他的话。

  I believe that he will succeed.我相信他会成功的。

  ◇ believe in 是一个动介型短语动词,表示“信奉;信仰”(指对某种思想、主张、观念、行动具有信心)和“信任(have trust in)”。如:

  They believe in God.他们信仰上帝。

  I believe in having plenty of exercise.我相信多锻炼有好处。

  ◇ believe和believe in后均可接表示人的名词或代词,但含义不同。试比较:

  I believe in him(I think he is a frustworthy man).我信任他。

  I believe him.(I believe what he says).我相信他的话。

  ◆ belieffaithtrustconfidence 都含有“相信”的意思。

  ◇ belief 指“承认某事是真的, 尽管有或没有确凿的证据”, 如:

  ◇ trust 指“信赖”、“信任”, 含有“坚定的信念”的意思, 如:

  ◇ confidence 指“在有证据的基础上相信”, 也常指“自信”、“有把握”, 如:

  She has great confidence in her success.她对自己的成功充满信心。

  ◆ besides;except;but

  ◇ 三者都可以用作介词。用于肯定句中时,except/but意为“除……外(不再有)”;besides意为“除……外(还有)”。请比较:

  All of them have seen the film besides Wu Dong. 除了吴东看过那部影片外,他们也都看过了。

  ◇ except后接名词、代词、-ing或不定式时,可以与but互换;except后接副词、介词短语时,一般不能为but所替换。如:

  This window is never opened except in summer. 除了在夏天,这个窗子从不打开。

  ◇ 用在否定句中,三者可以互换。如:

  除了你,没人能做这工作。

  ◇ be anxious for表示“渴望”,后面接名词或代词时,强调渴望得到某物或渴望了解某事;后面接sb.to do sth.时,表示“渴望某人能做某事”,其中for sb.to do sth.是不定式复合结构。
