Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. While文章正文：When and while are commonly used to talk about actions or events happening at the same time. However, there is a slight difference in their usage."When" is used to refer to a single, specific event that happens at the same time as another event. It emphasizes the momentary coexistence of two actions.For example, in the sentence "When I was cooking dinner, my friend called," the cooking and the phone call happened simultaneously. The focus is on the coincidence of these two events occurring at the same time."On the other hand, "while" is used to describe two ongoing or continuous actions that happen at the same time. It emphasizes the duration of the actions.For example, in the sentence "While I was cooking dinner, my friend called," both the cooking and the phone call were happening over a period of time. The focus is on the actions being carried out at the same time.Now let's move on to the practice questions:1. Fill in the blanks with "When" or "While":a) _______ I was cooking dinner, my friend called.b) _______ I was watching TV, the phone rang.c) _______ I was studying, my brother came into my room.d) _______ I was reading a book, it started to rain outside.e) _______ I was walking in the park, I saw my teacher.2. Choose the correct answer and fill in the brackets:a) _______ I was doing my homework, my favorite song came on the radio.1. When2. Whileb) _______ I was driving to work, I noticed a beautiful sunrise.1. When2. Whilec) _______ I was eating breakfast, my cat jumped onto the table.1. When2. Whiled) _______ I was sleeping, my phone rang.1. When2. Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. WhileIn conclusion, "when" and "while" both indicate actions happening simultaneously, but "when" emphasizes a single specific event, while "while" highlights ongoing or continuous actions. Practice using these words to improve your understanding and fluency in English.。
初中英语状语从句和练习题(含答案)
状语从句的分类一、时间状语从句时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since等。
时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。
注意：as（在……时候，因为），since（自从，因为），它们可以引导时间从句，并强调主句和从句的动作同事发生。
并且while有时还可以表示对比。
例如：（1）While my mother was reading the newspaper, I was watching TV.(read是延续性的动词，read和watch同事发生)I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。
（对比）（2）when（当……的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。
从句动作可与主语动作同事发生，也可在其后发生。
I was reading a book when she came into my room.(come是瞬间动词，只能用when引导，不能用while)I often missed my home when(while) I lived in NewYork.（live是延续性动词，when可用while代替）（3）when和while的区别还在于：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。
（4）as译作“一边……一边”、“随着……”，侧重主句和从句的动作同时发生。
有时可与when，while通用。
We always sing as we walk.我们总是边走边唱。

（一）、when，while都有“当……时候”的意思。
when既可表示某一点时间，也可以表示某一段时间。
在when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，可与主句中的谓语动词同时发生，也可在其后发生。
1、I was just reading a book when she came into my room.
她走进我房间时，我正在看书。
2、Were you writing when the teacher came in?
老师进来的时候，你在写信吗？
3、When he was a child he was always trying out new ideas.
他小时候就常常试验一些新的设想。
（二）、while只能表示某一段时间，不能表示某一点时间。
在while引导的时间状语从句中，其谓语动词只能是延续性的，而且也只能与主句中的谓语动词同时发生或存在。
例如：
1、While Jim was mending his bike, Lin Tao came to see him.
正当吉姆修自行车时，林涛来看他。
2、You can’t do your homework while you’re watching TV.
你不能一边看电视一边做家庭作业。
（三）、另外，when和while的区别还在于：while引导的时间状语从句多用进行时态，而when引导的时间状语从句多用一般时态。
例如：
1、While they were talking , the bell rang.
正在他们谈话的时候，上课铃响了。
2、I was doing my homework when my mother came back home yesterday evening.
昨天晚上妈妈回家的时候，我正在做家庭作
注意：
1) 如主句谓语动词表示的是短暂动作，从句时间状语指一段时间，when while as 三者可通用。
Peter came in while /as I was watching TV.当Peter进来的时候我正在看电视。
I was watching TV when Peter came in. 当Peter进来时我正在看电视。
2) as 和 when 可与非延续性动词连用，而 while 只能与延续性动词连用。
例如：He came in when/ as I was going to bed.我正要上床睡觉，他进来了。
3) as 和 while可用来指一段时间，但 as 强调主句与从句表示的动作同时发生，while强调主句表示的动作是在 while 从句的动作延续中发生。
As my mother sang those old songs, tears ran down her cheeks.
当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。
I came in while he was reading an interesting book in his room.。
