  在PTE英语学习中,语法永远是一个让人头疼的内容。枯燥的语法让人昏昏欲睡,丝毫没有学习下去的动力。下面就和小编一起看看英语中when和while区别。

  when

  什么时候,何时;什么情况下,什么场合下;(用于时间的表达方式之后)在那时;其时;当时(副词)

  什么时候,何时(代词)

  在…时候,当…时,在…期间,在…之后;在任何…时候(连词)

  I had an active social life when I was at college.

  我在大学时社交生活丰富。

  Steve was in a particularly bad mood when he got back.

  史蒂夫回来时心情特别不好。

  When will he be back from his holiday?

  他度假什么时候回来?

  I mind the time when we were in Beijing together.

  我想起我们一起在北京的时光。

  02while

  (while要特别注意学习不同的用法)

  在…期间,当…的时候;与…同时(连词)

  虽然,尽管(连词)

  (对比两件事物)…而,…然而(连词)

  一段时间;一会儿(名词)

  Flats in the downtown are expensive, while houses in the suburbs are cheap.

  市中心的公寓很贵,而郊区的房子很便宜。

  While I sympathize, I can't really do very much to help.

  虽然我很同情,但我实在帮不了什么忙。

  Did you sneak into my room while I was asleep?

  我睡着的时候你偷偷溜进我的房间了吗?

  The band played the guitar while we danced.

  我们跳舞时乐队弹起了吉他。

  While I was waiting at the bus stop, three buses went by in the opposite direction.

  当我在公共汽车站等车时,有三辆公共汽车朝相反的方向经过。

  I want to rest a while.

  我想休息一会儿。

  After a while, we naturally started talking about the children.

  过了一会儿,我们自然而然地开始谈论孩子们。

  They chattered away happily for a while.

  他们愉快地聊了一会儿。

  Life moves pretty fast. If you don't stop and look around once in a while, you could miss it.

  人生如白驹过隙。如果你不偶尔停下来四处看看,你可能会错过许多。

  03while和when的区别

  while和when在表示“当…的时候”时,有些同学会觉得难以区分,但这又是常考的语言点,很是让人苦恼。

  其实,要掌握它们的不同用法,先要了解动词的一个特征:短暂性动词还是延续性动词:

  实用英语语法 第十三讲 实义动词

  while从句的谓语必须是延续性的;when从句谓语短暂性和延续性都可以。

  It was midnight when we left the party.

  我们离开晚会时已是午夜。

  It's rude to speak when you're eating.

  吃饭的时候说话是不礼貌的。

  Please keep the doors closed while the train is moving.

  火车开动时请别开车门。

  考试考它们的区别,只可能两种情况:

  1)只能用when(从句谓语短暂性):

  I'll believe that when it happens.

  当事情发生了我才会相信。

  Turn off the lights when you leave.

  离开时把灯关掉。

  2)只用while(主句和从句都是进行时):

  While I'm doing my homework, my mother is preparing dinner.

  当我做作业时,我妈妈正在准备晚饭。

  It was raining hard while I was driving toward the town.

  谓语是延续性的,while和when可以互换,是没法考的。

  04while和whilst

  while和whilst这两个词先有哪个?很多人会以为是whilst吧?

  无其实while在古英语中就在使用了;而whilst是一个中古英语词汇。

  作为连词,在英式英语里它们是可以互换的,但美国英语没有保留whilst。

  He broke his hip whilst hunting.

  他打猎时摔伤了臀部。

  Breakfast is continental, whilst dinner is three courses from a set menu.

  早餐是欧式的,晚餐是三道菜的套餐。
