求英语大神!给我说说“when”和“while”的用法和区别，有例句最好!还有“not only…but also”用法及例句!谢谢!
When和While的区别 ①when是at or during the time that, 既指时间点，也可指一段时间，while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。 ②when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。 ③由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如： a. When the teacher came in, we were talking. 当此句改变主从句的位置时，则为： While we were talking, the teacher came in. b. They were singing while we were dancing. ④when和while 还可作并列连词。when表示“在那时”；while表示“而，却”，表对照关系。如： a. The children were running to move the bag of rice when they heard the sound of a motor bike. 孩子们正要跑过去搬开那袋米，这时他们听到了摩托车的声音。 b. He is strong while his brother is weak. 他长得很结实，而他弟弟却很瘦弱。
not only ……but also不仅而且
注意以下用法：
■主要用于连接两个对等的成分；若连接两个成分作主语,其后谓语动词与靠近的主语保持一致.如：
She likes not only music but also sport.她不但喜欢音乐而且喜欢运动.
The place was not only cold,but also damp.那个地方不但很冷而且很潮湿.
We go there not only in winter,but also in summer.我们不仅冬天去那儿,而且夏天也去.
Not only the students but also their teacher is enjoying the film.不仅学生们在欣赏这部影片,他们的老师也在欣赏这部影片.
■not only…but also…中的also通常可以省略,或换成too,as well（要置于句末）.如：
He not only washed the car,but polished it too [as well].他不仅冲洗汽车,而且还擦拭了它.
有时甚至连 but also 一并省略掉.如：
Justice must not only be done; it must be seen to be done.正义不但必须伸张,而且要让人看到正义得到了伸张.
She not only entered the competition—she actually won it!她不但参加了竞赛——而且居然获胜了!
■为了强调,可将not only置于句首,此时其后的句子通常要用部分倒装的形式.如：
Not only has she been late three times,she has also done no work.她不仅仅迟到了3次,她还没干一点活.
Not only do they need clothing,but they are also short of water.他们不但需要衣服,而且还缺水.追答
not only ……but also不仅而且

not only but also是倒装句或者不是倒装句，区别在上面其中倒装句类似用法还有only,so等引导状语从句的
追问如果是这样“过去进行时（）一般过去时”哪（）填什么when还是wh ile
while
追答when
用when，如果谓语是是进行时while
追问…意思说判断是用when 还是while只是和从句有关咯?
追答when既可以终止性动词也可以延续性动词，但是while肯定是延续性动词
从句的判断是看谓语动词，
追问…那就是判断用哪一个是根据从句的谓语是延续还是短暂咯?
追答bingo，然后延续性动词是有进行时的，短暂是没有的，所以一般来说进行时的动词用while
追问那就和主句的时态没多大关系咯?
追答主句从句时态都是一致的，无论时间when/while/as/since等等时间状语从，还是其他的宾语从来，定语从句。。
追问…呃大概懂
一般过去时when一般过去时/过去进行时
过去进行时when一般过去时/过去进行时
一般过去时while过去进行时
过去进行时while过去进行时
对吗？
追答when my mom walked into my room,I was doing my homework
My mom walked into my room,while I was doing my homework
对
追问…这样就好了嘛
谢谢(≧∇≦)
追答一般来说，你要注意是不是延续性动词噢

精锐莘庄老师温馨提示：
（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。
例如：
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
例如：
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.

when后面加瞬间动词，while后面加延续性动词追问
例句有吗
还有not only…but also
追答not only my mother but also l am happy. 就近原则
第3个回答 2015-04-28
when表示"当...时候", while表示"与此同时",或者一边一边,强调两个事情同时发生, not only... but (also) 不仅/不但...而且/还
when:
Lock the door when you leave. 你走的时候锁上门 (重点是要说锁门)
He was singing while playing the guitar. 他一边弹吉他一边唱歌 (两个事情同时发生)
This happens not only because you are so lazy, but also you have no responsibility.
之所以会这样,不仅因为你太懒,还因为你没有责任感

when后面可以跟短暂性动词或延续性动词，while后面只能跟延续性动词，when可以引导时间状语从句，也可以引导过去进行时，while引导过去进行时。
例子：I was doing my homework when my sister got home.
I was doing my homework while my sister was cooking in the kitchen.
not only but also表示不仅而且。例子 I not only finished my math homework but also finished my english homework我不但完成了数学作业还完成了英语作业。望采纳追问
