1)She likes to take a nap for a while after lunch. 她喜欢午饭后眯一会儿。
2)it takes a while to fit in the society for an overseas student. 留学生需要花一段时间适应当地生活。
While作连词:
1.引导时间状语

2)While he is speaking, he likes to do a lot of gestures. 他演讲的时候有很多手势。
2. 引导让步状语从句,意思是“虽然…但是….”(多放于句首)

4)Honey is sweet, but the bee stings. 蜂蜜很甜,但蜜蜂有刺蜇人。
二、When, while与as的用法区别
when ,as ,while 这三个词都可以引出时间状语从句,它们的差别是:when 从句表示某时刻或一段时间 as 从句表示进展过程,while 只表示一段时间。
一、根据从句动作的持续性来区分
若是“主短从长”型,即主句是一个短暂性的动作,而从句是一个持续性动作,此时三者都可用。如:
As [When, While] she was waiting for the train, she became very impatient. 她在等火车时,变得很不耐烦。
若是“主长从长”型,即主句和从句为两个同时进行的动作或存在的状态,且强调主句动作或状态延续到从句所指的整个时间,此时通常要用while。如:
I always listen to the radio while I'm driving. 我总是一边开车一边听收音机。
但是,若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时,则习惯上要用as。如:
He swung his arms as he walked. 他走路时摆动着手臂。
若是“主长从短”型,即主句是一个持续性动作,而从句是一个短暂性动作,此时可以用as或when,但不能用while。如:
It was raining hard when [as] we arrived. 我们到达时正下着大雨。
二、根据主句与从句动作是否同时发生来区分
若主句与从句表示的是两个同时发生的短暂性动作,含有类似汉语“一……就”的意思,英语一般要用as (也可用when)。如:
The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。
He jumped to his feet as the boss came in. 老板一进来他立刻站了起来。
若主句与从句表示的是两个几乎同时发生的短暂性动作,含有类似汉语“刚要……就”“正要……却”的意思,英语一般要用as(也可用when),且此时通常连用副词just。如:
Just as [when] the two men were leaving, a message arrived. 就在这两个人要离开的时候,突然有了消息。
三、根据是否具有伴随变化来区分
若要表示主句动作伴随从句动作同时发展变化,有类似汉语“随着”的意思,英语习惯上要用as,而不用when或while。如:
The room grew colder as the fire burnt down. 随着炉火逐渐减弱,房间越来越冷。
As time goes by my memory seems to get worse. 随着时间的流逝,我的记忆力似乎越来越差。
若不是引导从句,而是引出一个短语,则用with,不用as。如:
With winter coming on, it's time to buy warm clothes. 随着冬天到来,该买暖和衣裳了。
The shadows lengthened with the approach of sunset. 随着太阳下落,影子也逐渐伸长。
四、根据从句动作的规律性来区分
若暗示一种规律性,表示“每当……的时候”,英语一般要用when。如:
He smiles when you praise him. 你夸奖他时他总是笑笑。
It’s cold when it snows. 下雪时天冷。
He smiles when you praise him. 你夸他时他总是笑笑。
五、根据主从句动作的先后顺序来区分
若主句与从句所表示的动作不是同时发生,而是有先后顺序时,一般要用when。如:
When he arrives he'll tell us all about the match. 等他到了,他会好好给我们讲讲那场比赛的情况。
When she had finished she waited as though for a reply. 她讲完之后等了等,仿佛是在等候回答似的。

while 的使用方法
连词“while”具有两种意义,因此为了避免误用,使用时需多加注意。
“while”作为连词来使用的时候,表示“同时性”或“对比性、对立”。根据文章的内容可明确该词具体表达了哪一种意义的情况固然存在,但如同下文中所展示的相反情况同样存在。
The temperature decreased while the growth rate increased.
这句话可产生“温度下降的同时生长速度加快了”和“与温度下降所不同的是,生长速度却加快了”两种翻译。
正解是:若要使后者的翻译成立,“decreased”和“while”之间的逗号必不可少,因此目前的情况下无法直接确定此句的翻译。为了使上文的句意能够明确,就该如同下文的例句一般进行修改。
同时性:
(1) The temperature decreased as the growth rate increased.
(2) The temperature decreased, and simultaneously, the growth rate increased.
(3) As simultaneous phenomena, the temperature decreased and the growth rate increased.
对比性:
(4) Although the temperature decreased, the growth rate increased.
(5) The temperature decreased, though the growth rate increased.
(6) The temperature decreased, but the growth rate increased.
(7) Whereas the temperature decreased, the growth rate increased.
(8) The temperature decreased, whereas the growth rate increased.
(9) Despite the fact that the temperature decreased, the growth rate increased.
*“while”除了连词以外还能作为其他此类来使用,不同的词性皆具其特有的意义。
when与while的用法与区别
1.
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。
2.
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。
3.when和while的区别
when和while的区别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。
例如:
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。
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.
