while后的句子谓语动词并不一定是ing形式，具体需要根据上下文和时态来定，while后的句子时态可以是一般现在时，也可以是过去时态、进行时态等。while的具体用法如下：
1、“当……时候”， 引导时间状语从句(从句动作必须是延续性的)。
Please don't talk so loud while others are working. While I was cleaning the window，my finger was seriously cut.
2、“虽然，尽管”相当于although，引导让步状语从句(常把while放在句首)。
While she is a top student， she has some shortcomings. While the Internet is bridging the distance between people， it may also be breaking some home or will cause other family problems.
3、“只要，如果”等于as long as，引导条件状语从句。
There is hope while there is life. While you study hard， your effort will pay off.

While用法小结
一、while作名词用,表示“一会儿”“一段时间”
1.She likes to lie down for a while after lunch.
她喜欢午饭后躺一会儿.
2.Coming to another country to study requires a big adjustment and it takes a while to fit in.

二、While作连词(1)引导时间状语
1.We must strike while the iron is hot.趁热打铁.
2.While she was listening to the radio,she fell asleep.
她听着收音机睡着了.
(2)引起让步状语从句,意思是“虽然…但是….”、“尽管…但是…”(多放于句首)1.While he loves his students,he is very strict with them..
虽然他爱他的学生,可是他对他们很严格.
2.While these experiments are interesting and useful,it is important to remember that they may not always tell us much.(BookIIIp125)

(3)引起条件状语,意思是“只要”
1.While there is life there is hope.只要生命存在,就有希望.
2.While there is a way there is away.有志者事竟成.
三、While作并列连词用,意思为“而,然而”,表对比.而but表转折.注意用心比较体会while与but的句中用意
1.Some people waste food while others haven't enough.

四.while,when,as的用法区别
都译为“当…的时候”,区别为：when后的从句谓语动词既可是延续性动词,也可是短暂性动词,而且还可作并列连词,译为“这时”.但以下句型一定用when,作并列连词：
句型A：be about to do…when…正要做…这时(发生另一事)
句型B：was/were doing…when…正在…这时(发生另一事)
句型C：had done…when…刚要做…这时(发生另一事)
1.We were about to set out when it began to rain.

2.He had hardly sat down when his mobile rang.
他刚一坐下手机就响了.
3.I was walking along the bank of the river when I fell into it.
我正沿河岸散步突然掉进水里.
while后的从句谓语动词只能是延续性动词,强调主从句的两个动词同时发生；while也可作并列连词,表示两个动作的对比,译为“而”“然而”.as则表示两个变化中的动作的同时性,译为“一边…一边…”.
1.While his mother was cooking in the kitchen,the boy fell asleep in the chair.
(在一个延续动作过程中发生另一个动作)
2.He hurried home,looking behind as he went。
他匆匆回家,边走边往后看。本回答被提问者采纳
