while的用法總結大全

另外while還有別的用法,while引導狀語從句,有以下兩種含義:

1.表示某個動作正在進行的'同時,另一動作也在進行之中,這時主從句都用進行時態,有對同類的兩個動作進行對比的意味.如:

While I was playing the piano,she was dancing.我在彈鋼琴,她在跳舞.

While Jim is picking apples,Kate is carrying apples to the truck.吉姆正在摘蘋果,凱特正在把蘋果搬到卡車上去.

2.表示某個動作正在進行時,又發生了另一動作(該動作用一般過去時).如:

While I was reading,I fell asleep.我讀着讀着就睡着了.

While we were swimming in the river,we saw a fish jump out of the water.我們正在河中游泳時,看見一條魚躍出了水面.
