過去進行式（2）

when和while的差別

(一) when，while都有「當…時候」的意思。 when既可表示某一點時間，也可以表示某一點時間。

在when引導的時間狀語子句中，其謂語動詞可以是延續性的，也可以是非延續性的，可與主句中的謂語動詞同時發生，也可在其後發生。如：

I was just reading a book when she came into my room.

當她走進我房間時，我正在看書。

Were you writing when the teacher came in?

老師進來的時候，你在寫信嗎？

When he was a child, he was always trying out new ideas.

他小時候就常常試驗一些新的設想。

(二) while只能表示某一段時間，不能表示某一點時間。在while引導的時間狀語子句中，其謂語動詞只能是延續性的，而且也只能與主句中的謂語動詞同時發生或存在。如：

While Jim was mending his bike, Lin Tao came to see him.

正當吉姆修自行車時，林濤來看他。

You can’t do your homework while you’re watching TV.

你不能一邊看電視一邊做家庭作業。

(三) when和while的差別還在於: while引導的時間狀語子句多用進行時態，而when引導的時間狀語子句多用一般時態。如：

While they were talking, the bell rang.

他們談話的時候，上課鐘響了。

I was doing my homework when my mother came back home yesterday evening.

昨天晚上媽媽回家的時候，我正在做家庭作。
