【易混连词比较篇】

1. when和while

两个词都可以表示“当……时”,且可以引导时间状语从句。when引导的时间状语从句的谓语动词既可以是延续性的,也可以是终止性的;而while引导的时间状语从句的谓语动词只能是延续性的。如:

He was doing his homework when I came in. 当我进来时,他正在做家庭作业。

While / When I was in the town, I saw him twice. (当)我在城里时,见过他两次。

Strike while the iron is hot. 趁热打铁。

when还可译作“这时”,而while可译作“而”。如:

He was playing football outside when it began to rain. 他正在外面踢足球,这时天下起雨来。

He is tall while his elder brother is short. 他个子高,而他哥哥个子矮。

2. though和as

两个词都可表示“虽然”,且可引导让步状语从句。though引导的从句用正常语序;as引导的从句要用倒装语序,即把从句中的表语、状语或动词原形放在as之前。试比较“尽管天气冷,可他仍继续工作。”的两种译法:

Cold as it was, he went on working.

Though it was cold, he went on working.

3. for, because, as和since

四个词都可表示“因为”。for是并列连词,语气最弱,是对前面分句加以解释或推断的原因。引导的分句一般置于句末,从句前要用逗号;because表示产生某结果的必有原因,语气最强,引导的从句常置于句首或句末,放在句首时通常用逗号与主句隔开;as表示原因时,语气不像because那么强,可译为“因为,由于”,引导的从句可以置于句首;since可译为“既然”,往往表示一些显而易见的原因,语气不如because的强,引导的从句常置于句首。如:

It must have rained last night, for the ground is wet. 昨晚一定下了雨,因为地面是湿的。

As she was in a bad mood, we left her alone. 由于她心情不好,我們就没去打扰她。

He is absent from school because he is ill. 因为生病,他没来上课。

Since everybody is here, lets begin. 既然大家都到齐了,我们开始吧。
