一、 while 用作名词时,意为“一段时间,一会儿”。例如:
I stayed there for a short while.

(我在那儿呆了一小会儿。)

The postman came a short while ago.

(邮递员刚刚来过。)

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:

While I was watching TV, the bell rang.

(我看电视时,铃响了。)

Meimei watched TV while she ate her supper.

(梅梅边吃晚饭边看电视。)

2. 意为“虽然,尽管”,引导让步状语从句。例如:

While it was late, he went on working.

(虽然很晚了,但他还在继续工作。)

While he is in poor health, he works hard.

(虽然他身体不好,但他还是努力工作。)

3. 连接两个并列句子,表示“对比”关系。例如:

He went out for a walk, while I stayed at home.

(他出去散步了,而我却呆在家里。)

I like singing while she likes dancing.

(我喜欢唱歌,而她喜欢跳舞。)

You like sports, while I prefer music.

(你喜欢体育,而我更喜欢音乐。)

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:

While he was tired, he went on working.

(虽然他累了,但他还是继续工作。)

( while 引导让步状语从句)

While he was tired, he would have a rest.

(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:

While he was ill, he went there. (= While ill, he went there.)

(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:

While we were talking, the teacher came in.

(我们正在谈话时,老师进来了。)

The bus had left when we arrived at the bus stop.

(当我们到达车站时,公共汽车已经开走了。)

( arrive 是非延续性动词,因此,此句中的 when 不能用 while 替换。)

When / While we were having a meeting, our teacher came in.

(我们正在开会时,老师走了进来。)

( 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:

While the teacher was speaking, the students were listening.

(老师讲课时,学生们在听。)

While he was writing, I was reading.

连词while大致有以下四种用法:

1.引导时间状语从句,意为"当……的时候;和……同时",此时的主从句谓语动作同时发生,从句谓语通常是延续性动词。如:

Mary watched TV while she ate her supper.玛丽边吃饭边看电视。

While she was listening to the radio, she fell asleep.她听着收音机睡着了。

while引导从句时,如主从句的主语一致,且从句谓语又含有be,则从句主语和be可省略。while后可直接跟现在分词、名词、形容词或介词短语。如:

We are teachers while (we are) serving as students.我们边当老师边当学生。

While (he was) yet a youth, he gained many prizes.他年轻时就曾多次获奖。

He caught a cold while(he was) on vacation.他度假时患了感冒。

2.表示对比或转折,意为"而;然而"。此时,while一般位于句中。如:

Some people waste food while others haven't enough.有些人浪费粮食,然而有些人却吃不饱。

You like sports, while I prefer music.你喜欢体育,而我更喜欢音乐。

3.表示让步,通常位于句首,意为"尽管;虽然"。如:

While I agree with your reasons, I can't allow it.尽管我同意你的理由,但我不能允许这样做。

While he loves his students, he is very strict with them.虽然他爱他的学生,可是他对学生们很严格。

While (he was) respected, he is not liked.他虽受人尊敬,但并不被人喜欢。

4.表示条件,意为"只要",其意思和用法相当于as long as。while可位于句首,也可位于句中。如:

You don't have to worry while we are here.只要我们在,你就别着急。

There will be life while there is water and air.只要有空气和水,就有生命。

While there is life, there is hope.留得生命在,不怕没希望。

5.意为"同时;也"。如:

While the book is welcomed by schol-

ars, it will make an immediate appeal to the general readers.这本书受到学者的欢迎,同时也会引起一般读者的兴趣。

6.意为"趁着"。如:

Make hay while the sun shines.晒草要趁阳光好。(谚)

Strike while the iron is hot.趁热打铁。(谚)

While the roses are yet in bloom, will you come with me to see them?趁着玫瑰花还开着,你和我一道去看看好吗

再想想哦~~~
