状语从句是指句子用作状语时,起副词作用的句子。状语从句中的从句可以修饰谓语、非谓语动词、定语、状语或整个句子。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。 状语从句的时态特点 一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”。例如如下: I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。 (这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,绝不可用will arrive) As soon as I have finished this work, I will have gone home.如果我早完成工作的话,我现在已经到家了.。 (从句中的谓语动词用现在完成时have finished,表示将来完成时,绝不可用will have finished)
状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如: 1. Naturally, our grandparents were pleased to get our phone call.(副词)(www.ws46.Com) 当然,我们的祖父母乐于接到我们的电话。 2. We worked hard, from sunrise to sunset.(介词状短语) 我们工作得很努力,从日出到日落。 地点状语从句 常用引导词:where 特殊引导词:wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. 一般来说,有工厂的地方空气污染就严重。 Wherever you go, you should work hard. 无论你去哪里,你都应该努力工作。
地点状语从句一般由连接副词where, wherever等引导,已经形成了固定的句型,例如: They were good persons. Where they went, there they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。 目的状语从句 常用引导词:so that, in order that 特殊引导词:lest, in case, for fear that,in the hope that, for the purpose of , to the end that The boss asked the secretary to hurry up with the letters so that he could sign them. 老板要求秘书快写函件以便他能在上面签字 |
