状语从句—— 时间状语从句和地点状语从句

一、概述 状语从句是句子的状语由一个从句充当，来修饰主句中的动词，形容词或副词等。状语从句都由从属连词引导，与主句连接，放在句末时，一般不在前面加逗号。 状语从句根据它表示的意思可分为时间，原因，条件，比较，结果，目的等类型。

Grammar

状语从句—— 时间状语从句和地点状语从句

时间状语从句 是由 when, as, while, after, before, since, until, as soon as 等从属连词引导的状语从句。 时间状语从句中的谓语动词不能用一般将来时，只能用一般现在时表示将来发生的动作或存在的状态。 e.g.

I will call you as soon as I arrive there.我一到那儿就给你电话。 He is going to visit her aunt the day he arrives i

n Beijing.他一到北京，就去看他姨妈。

Grammar

地点状语从句 通常是由 where, wherever 引导的状语从句。

e.g.

Where I live there are plenty of trees. 我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。

二、比较几组时间状语从句的连接词

状语从句—— 时间状语从句和地点状语从句

while, when, as 1 ） as, when 引导短暂性动作的动词。

e.g.

Just as / Just when / When I stopped my car, a man came up to me.

2 ）当从句的动作发生于主句动作之前，只能用 when 引导这个从句，不可用 as 或 while 。

e.g.

When you have finished your work, you may have a rest. 3 ）从句表示 " 随时间推移 " 连词能用 as ，不用 when 或

while 。 e.g. As the day went on, the weather got worse. 　 日子一天天过去，天气越变越坏。

Grammar

状语从句—— 时间状语从句和地点状语从句

until ， till

此两个连词意义相同。肯定形式表示的意思是 " 做某事直至某时 " ，动词必须是延续性的。否定形式表达的意思是 " 直至某时才做某事 " 。动词为延续性或非延续性都可以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 肯定句I slept until midnight. 我一直睡到半夜时醒

了。 Wait till I call you. 　 等着我叫你。

Grammar

状语从句—— 时间状语从句和地点状语从句

ow. 　 直到你教我后，我才会做。

e.g.

Until you told me, I had heard nothing of what happened.

直到你告诉我以前，出了什么事我一点也不知道。 2 ） until when 疑问句中， until 要放在句首。

e.g.

Until when are you staying? 　你呆到什么时候？ Until next Monday. 　呆到下周一。

Not until I began to work did I realize how much time I had wasted.

　 直到我开始工作，我才认识到了我已蹉跎了几多岁月。

Grammar

Grammar

状语从句—— 时间状语从句和地点状语从句
