一、while用作名词时,意为“一段时间,一会儿”。例如:Istayedthereforashortwhile.二、while用作连词时,有以下几种含义:1.意为“当……时候,和……同时”,引导时间状语从句。例如:WhileIwaswatchingTV,thebellrang.(我看电视时,铃响了。)2.意为“虽然,尽管”,引导让步状语从句。例如:Whileitwaslate,hewentonworking.(虽然很晚了,但他还在继续工作。)3.连接两个并列句子,表示“对比”关系。例如:Hewentoutforawalk,whileIstayedathome.(他出去散步了,而我却呆在家里。)三、while引导状语从句时,应注意以下几点:1.while引导的时间状语从句既可放在句首,也可放在句末;而while引导的让步状语从句一般放在句首,不放在句末。另外,也可以从意义上加以区分。例如:Whilehewastired,hewentonworking.(虽然他累了,但他还是继续工作。)(while引导让步状语从句)Whilehewastired,hewouldhavearest.(他累了就休息一会儿。)(while引导时间状语从句)2.while引导让步状语从句时,如果从句的主语和主句的主语相同,那么从句的主语和谓语动词be都可以省略。例如:Whilehewasill,hewentthere.(=Whileill,hewentthere.)(虽然他有病,但他还是去那里了。)3.while和when都可以引导时间状语从句,但应注意:while引导的时间状语从句中的谓语动词必须是延续性的动词;而when引导的时间状语从句中的谓语动词既可以是延续性动词,也可以是非延续性动词。当时间状语从句中的谓语动词是延续性动词时,while和when可以互相替换。例如:Whileweweretalking,theteachercamein.(我们正在谈话时,老师进来了。)(have是延续性动词,因此,句中的when可以用while替换。)4.while引导的状语从句还可以表示“某个动作正在进行的同时,另一个动作也在进行之中”。例如:Whiletheteacherwasspeaking,thestudentswerelistening.(老师讲课时,学生们在听。)Whilehewaswriting,Iwasreading.

真全面啊我总结就是 当时间讲的时候 是连词 作“当”讲,与when的区别是 前者表示一段时间 后者表示点时间当名词讲的时候 指一段时间 比如for a while :一会儿还当然而讲 表示转折 He likes football while i like basketball.

when和while的区别如下:
1、从句中用法区别:
while引导的从句只能用延续性动词,而when引导的从句可以用延续性动词也可以用非延续性动词。
2、从句时态的区别:
when引导的从句动作和主句动作可以同时发生或在之后发生,while只能同时发生或存在。
3、具体含义的区别:
when是既指时间点,也可指一段时间,while是during the time that,只指一段时间。
扩展资料:
时间状语从句:
由when,while引导,用表示时间的连词连接一个句子作状语,这样的主从复合句就是时间状语从句。
在复合句中,担任状语成分的从句称为状语从句。时间状语从句说明主句动作发生或进行的时间。状语从句由连词引导,其位置通常可以放在句首或句末。放在句首时,常用逗号与主句分开;放在句末时,从句前面往往不加逗号。
