When與while使用的差別

When與while使用的差別:

while (during the time)定義:

while當從屬連接詞時,表「在……的時後;與……同時」,用於連接兩個「發生時間接近」或「同時」的子句;一個為主要子句(含主詞與動詞),另一個由while引導的從屬子句(含主詞與動詞)。

當連接的兩個子句中的動詞都是「持續性動詞」時;持續性動詞是指該動詞的動作會「延續、持續做一段時間」,通常以「進行式」呈現。

while置於句首:句中有逗號

While+過去進行式,

(長時間持續性動詞)

過去簡單式(短時間瞬間動詞).

過去進行式(長時間持續性動詞).

he woke up(醒來).

While I was doing the laundry,

 my husband was cleaning the house.

when(at the time)使用時機:
