【摘要】词海茫茫,高考7000个词汇如何复习?抓不住重点? 话说单词应该放在句子中记忆,才能事半功倍,小编精心整理了2013高考英语高频词汇:because/since/as/for,此乃精华中的精华,帮你抓住重点,做到有的放矢。
◆ 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。
◇ 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 to; be anxious for; be anxious about ;be anxious that◇ be anxious to表示“急于”、“渴望”,其中to是不定式符号,后面接动词原形;
◇ 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。
◇ be anxious about 表示“对…感到不安”、“为…担心”、“为…忧虑”;◇ be anxious that表示“渴望”,后面接从句,that从句的谓语动词须用虚拟语气;
