时间状语从句
【语法感悟】
回顾课文语法,用方框中所给单词或短语的适当形式填空。
1. While they were crossing the Atlantic, many people died.
2. After they landed, their first winter was worse than any English winter.
3. We stayed there until she arrived.
4. He has made a lot of progress since he started to learn English last month.
5. And my family always go somewhere interesting as soon as the holiday begins.
【语法精讲】
1. 含义:用从句来表达一件事情或一个行为发生的时间,这样的从句就叫时间状语从句。
2. 常见的引导时间状语从句的连词:
(1) when表示“当……的时候”,主句的动作和从句的动作可以同时发生,也可以先后发生。
(2) while表示“当……的时候”,强调主句和从句的动作同时发生,从句的谓语动词必须是延续性动词。
【典例】
—I asked him a question, but he didn't reply.
—Maybe he C about something else while you were asking.
A. thought B. thinks C. was thinking
解析:考查时态。句意:——我问了他一个问题,但他没有回答。——也许你问的时候他在想别的事情。根据were asking可知事情发生在过去,同时“思考”这个动作与“询问”这个动作是同时进行的,故应用过去进行时。故选C。
(3) before表示主句的动作发生在从句的动作之前。
(4) after表示主句的动作发生在从句的动作之后。
【典例】
Check what you have written B you hand in your application form.
A. while B. before C. after
解析:考查连词。句意:在递交申请表之前,先检查你所写的内容。while当……的时候;before在……之前;after在……之后。根据句意可知,应在递交申请表之前先检查下你所填写的内容,所以用before。故选B。
(5) since表示“自从……”,从句中的动词一般表示动作的起点,用一般过去时;主句中的动词表示动作延续的情况,一般用现在完成时。
(6) until的用法:
①表示“直到……为止”,主句谓语动词是延续性动词时,主句和从句都用肯定式;
②表示“直到……才”,主句谓语动词是非延续性动词时,主句用否定式,从句用肯定式。
【典例】
(2021·吉林)Ann didn't know anything about the news B Mrs Brown told her.
A. because B. until C. if
解析:考查连词。句意:直到布朗夫人告诉安,她才知道这个消息。本题主句是否定形式,后面用until构成:not
