以下是有关while when as三者的用法，希望帮到你，满意的话还请采纳哦！
while与when以及as之间的区别。

1. 当从句中的谓语动词是持续性的动作时,我们可以用while, when或as。

While / When / As I was walking down the street, I noticed a police car in front of the bank.我顺着马路往前走时,发现银行门前停着一辆警车。

2. 当从句中的谓语动词表示瞬间动作时,不可用while。

He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。

3. 如果谈论两个长动作,最常用的是while。

While John was sitting biting his nails, I was working out a plan to get us home. 约翰坐在那里咬指甲时,我想出了一个回家的办法。

不过, as是可以用来说明两种正在发展或变化的情况的,这时as引导一个持续性的动作,主句中的动作与之同时进行。

As we talked on, he got more and more excited. 我们继续往下谈的时候,他越来越兴奋。

4. 如果表示两个短动作或事件同时发生,最常用的是as或just as,也可用when。

Just as he caught the ball, there was a tearing sound. 当他抓住球的时候,有一种撕裂的声音。

I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。

while的用法可从下述几点理解与运用。

一、while意为“当……时候”,指一段时间,不能用来表示一个时间点。

While the discussion was still going on, George came in. 当讨论还在进行时,乔治走了进来。

二、while意为“而;然而”,表示转折。

There're plenty of rain in the southeast, while there's little in the northeast. 东南部雨量充足,而西北部则很少下雨。

三、while意为“虽然;尽管”,表示让步。

While I admit his good points, I can see his shortcomings. 尽管我承认他的优点,但我还是能看到他的缺点。

四、while意为“只要”,表示条件。

We can surely overcome these difficulties while we are closely united. 只要我们紧密地团结一致,一定能克服这些困难。

五、while从句中的省略。

当while从句中的主语与主句的主语一致,且含有be的某种形式时,从句中的主语连同be可同时省略。

While listening to the radio, she fell asleep. 她在听收音机时睡着了。

While in London, he studied music and painting. 在伦敦时,他学习音乐和绘画。

六、while可用作名词,意为“一会儿;一段时间”。

作名词用时,主要用于短语中: after a while “过了一会儿”; all the while “一直,始终”; a short / little while ago “刚才”; once in a while “偶尔,间或”; wait / rest(for) a while “等 / 休息一会儿”。

I haven't seen her for a long while.我好久没有看见她了。

Where have you been all this while?这一阵子你到哪去了?

He usually goes to work by bike, but once in a while he goes by bus. 他通常骑自行车上班,但偶尔也乘公共汽车。

I looked everywhere for the letter, but it was in my pocket all the while. 我到处找那封信,却不知它一直在我口袋里。

Answer 2

a.while
while引导时间状语从句,意为"当……的时候;和……同时",此时的主从句谓语动作同时发生,从句谓语通常是延续性动词。
另一方面，这种句子是语感形成的，读的多了，遇到就自然选了

Answer 3

while
就是说我很擅长英文 而他很擅长日语
表示转折
所以when肯定不对
不然的话就会变成
我很擅长英语当他很擅长日语 意思都不通顺
as更不行
我很擅长英语像他很擅长日语 两者没有关联点

Answer 4

选A,表两者比较,语气较弱。while有时也可表转折。至少when和as都可引导时间状语从句，但不符合此句语境。

Answer 5

选A while在此表比较

as与when、 while的用法区别。 ①下列情形时,只用as, 而不用when或while。 1)用于表示同一个人的两种动作交替进行,指一边----一边. 如: The girl sings as she goes to school. He looked behind occasionally as he went forward in the forest. 2)表示两个同步发生的动作或行?意思是随着-----的发展.如: As time went on / by, she became more and more beautiful . As children get older, they become more and more interested in everything. 3)表示两个短暂行为或事情几乎同时发生.如:I watched her as she read the book. I thought of it just as you opened your mouth. Just as the flying worm hit her face, she gave a loud cry. 4)接在名词后面表示某一个年龄段时.如: As a young man, he was active in sports. ②when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。如:When I was at college, I could speak several foreign languages. When the clock struck twelve, I had slept for 2hours. ③ while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:Work while you work. Play while you play.
