句子中的while为连词，引导状语从句，意思是“当...的时候和...同时”之意。
1)当while表示“当...的时候”时，强调在某事发生或进行期间，指某一时间段，所引导的从句中谓语动词通常是延续性动词。
例如:
While Sandy was filling out the forms, I called Jimmy from the airport.
在桑迪填写表格的时候，我从机场给吉米打了一个电话。
Someone broke into her house while she was on vacation.
当她在外度假时，家中被盗了。
She was talking on the phone while watching TV.
她一边打电话一边看电视。
另外。连词when也可以表示“当...的时候”的意思，表现在具体的某一时间点或一段时间中(at or during the time that something happens),所引导的从句中的谓语动词既可为瞬间性动词也可是延续性动词。
例如:
He was quite shocked when l told him.当我告诉他时，他十分震惊。
When he was at Greenfield High,he always played defense.
他就读绿地中学期间总是打后卫。
when还表示“当某事刚一发生或之后的时候”，这时它所引导的从句谓语动词仅为瞬间性动词。
例如:
When the meal was finished, my mother washed up and brewed a pot of tea.
吃过饭后，我老妈把所有东西都洗干净，沏了一壶茶。
I'll call you again when l get home.
我到家后再给你打电话。
2)当while表示“而；然而；但(是)”时，则用来说明或强调两种事情或情形的不同。
例如:
I do every single bit of housework while he just does the dishes now and again.
我要干每一件家务，而他只是有时洗洗碗筷罢了。
Tom is very outgoing and confident while Kathy's shy and quiet.
汤姆十分外向、自信，而凯西却腼腆文静。
