我是硼锂铜老师,通过逻辑记忆英语语法。
很多文章都梳理过时间状语从句中when while as的区别,你们看懂了吗?试试看硼锂铜老师的讲法,能不能更清晰理解[可爱]
先建立一个基本框架:主句和从句各有一个谓语动词
这两个谓语动词可以是持续性的(work),也可以是短暂性的(jump)
这两个谓语动词可以是同时发生的,也可以是一前一后的
先记结论:
(1)只要是同时,as就能用(as侧重强调同步性)
(2)只要不同时,肯定就用when
(3)同时 持续,才能用while (while侧重强调时间性,“得在什么时候干什么事儿”)
(4)进行时态爱while
先看例句体会一下,再细说
She hurried home, looking behind as she went.
一边回头望一边走,同时,两个都是持续性动作——只要是同时,就能用as,侧重同步性
I will go home when he comes back.
一先一后,不同时,肯定是when
Strike while the iron is hot.
同时,持续性动作,侧重的是你得当铁热的时候打,强调时间性而不是同步性,用while
I kept silent while he was speaking.
同时,持续性动作,进行时态,多用while
While适用情况:同时 持续性,侧重强调时间性,表述重点在于主句的动作在是从句那段时间内发生,所以多用进行时态
Please don’t speak so loud while others are working.
I kept silent while he was speaking.
As适用情况:①同时 持续性,侧重同步,表述重点在于两个动作是一起发生的,一边……一边……,或者“随着”
②同时 短暂性,跟when可以替换
She hurried home, looking behind as she went.
The theory proved to be correct as time went on.
As it grew darker,it became colder.
The students took notes as they listened.
The little girls sang as they went.一边走一边唱
再看这一句:
It was raining hard when[as]we arrived. 感受一下,强调raining是在we arrived的时间段发生吗?并不,就是一个客观描述,所以用when和as都行
如果主从句不是同时发生,那就一定用when了
I will go home when he comes back.
When the dinner was finished, tony washed the dishes.
总结:同时 持续性 while(得在某时间干或不干什么事儿) as(同步感、伴随感)
同时 短暂性 when as
前后 持续性 when
前后 短暂性 when
