◆ 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。
belief faith trust confidence 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: belief in ghosts.相信有鬼。
faith 指“认为有确凿证据或道理而完全相信”, 如: I have faith in his ability to succeed. 我相信他有成功的能力。
trust 指“信赖”、“信任”, 含有“坚定的信念”的意思, 如: enjoy the trust of the people得到人民的信任。
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 except/but Wu Dong. 除了吴东外,他们都看过了那部影片。 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: I’ll do everything except/but cook. 除了做饭,我什么事情都干。 This window is never opened except in summer. 除了在夏天,这个窗子从不打开。
