【答案】 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
