长袖旗袍-什么是意识流

2020年10月25日发(作者:袁凤兰)



时间状语从句
常用引导词:when, while, as, as soon as, before, after, tilluntil, since

1、when, while, as
(1)三者均可表示“当……时候”,如果主句表示 的是短暂的动作,而从句表示的是一段时间,三者
可通用。如:


I met Kang Li whilewhenas I was walking along the street.当我沿街散步时碰见了康丽。
Don’t make any noise whilewhenas I am recording. 我录音时(你们)别发出声音。
(2)while
1)while只能与持续性动词连用,且常用进行时态。表示主句的行 为在从句行为进行的过程中发
生。如:
While they were crossing the Atlantic, many people died. 他们中的很多人在横渡大西洋
时丧生了。


电视。


3)表示“然而”,主句和从句是两个对应的动作。如:
Lucy likes dancing while Lily likes doing sports. 露西喜欢跳舞而莉莉喜欢运动。
2)表示主句和从句的动作同时发生。如:
While the wife was cooking, the husband was watching TV. 妻子在做饭的时候,丈夫在看
(3)when
1)when既可以和持续性动作连用,也可 以和瞬间性动作连用,主句与从句描述的动作既可以同
时发生,也可以先后发生。如:


When the weather is fine, many people go out for a walk. 天气好时,很多人都出去散步。
When I got home, I found my baby girl singing in the sitting room. 我到家时,发现我
的小女儿正在客厅里唱歌。
2)表示“某人正在做某事,突 然……”,主句用过去进行时,从句用一般过去时,表示一个动作
正在进行的时候,另一个动作(突然) 发生了,强调后一动作发生的突然性。如:



We were talking when the teacher came in. 我们正在讲话,老师(突然)进来了。
试比较:
While we were talking, the teacher came in. 我们正在讲话的时候,老师进来了。(不强调
突然性。)


3)表示“某人正要做某事,就在这时……”,主句用过去将来时,从句用一般过去时。如:
I was leaving when somebody touched my shoulder. 我正要离开,就在此时有人碰了一下我



的肩膀。
(4)as
as与when用法相似,但着重强调主句动作与从句动作同时发生,有“随着 ……”或“一边……
一边……”之意。如:
