二、词义辨析:


though,although,as

这些连词均可表示“虽然,尽管”之意。 though和although在意义上几乎毫无区别,但文体上后者是较正式用词,语气比though强。此外,在习惯用法上这两个词仍有以下一些差异:1.though可引出倒装语序的让步状语从句,although 则不能。2.though可与even连用,although则不能;在as though结构中,只用though,不能用although。3.though可以置于从句末,而although则不能。4.引出省略句时,通常用though。 as引出让步状语从句只用于倒装语序结构中,语气强于上述两个连词。


三、词义辨析:


as,because,for,since

这些连词均含有“因为”之意。 as从属连词,语意较because,since弱,着重在主句,所表示的原因或理由是“附带的”。 because从属连词,语意强,着重直接的原因或理由,所引出的从句是全句的重心,用以回答why提出的问题。 for并列连词,语气较弱,所引出的句子一般放在后面,表示附带说明的理由或推断理由。 since语意比because弱,但比as强,一般用于表示“由于大家已知的事实”。


四、词义辨析:


when,while,as

这些连词均可表示“当……时”引出时间从句。 when所引导的从句,其谓语动词既可是持续动词,也可是短暂动词;谓语动词动作发生的时间可以与主句谓语动词的动作是同时,或之前、之后。 while句中的谓语动词应为持续动词,不用短暂动词,谓语动作发生的时间通常与主句谓语动词动作发生时间是同时。 as侧重指从句与主句的动作同时进行,谓语动词可以是持续性的,可以是短暂性动词。
