1. 構(gòu)成
was / were+動(dòng)詞的現(xiàn)在分詞。
2. 基本用法
(1) 表示過(guò)去某一時(shí)間點(diǎn)或一段時(shí)間正在進(jìn)行的動(dòng)作。如：

(2) 過(guò)去進(jìn)行時(shí)與 always, forever, continually等副詞連用，表示滿(mǎn)意、稱(chēng)贊、驚訝、厭惡等表示感情色彩。如：

3. 過(guò)去進(jìn)行時(shí)和一般過(guò)去時(shí)的區(qū)別
(1) 過(guò)去進(jìn)行時(shí)通常表示一個(gè)過(guò)去正在進(jìn)行的動(dòng)作；而一般過(guò)去時(shí)則通常表示一個(gè)過(guò)去已經(jīng)完成的動(dòng)作。如：

(2) 少數(shù)動(dòng)詞如rain, snow, cough, wear, feel, work等的一般過(guò)去時(shí)并不表示動(dòng)作完成，這時(shí)用兩種時(shí)態(tài)都可以，且含義區(qū)別不大。如：
It snowed / was snowing all day yesterday. 昨天下了一天的雪。
She didn’t feel / wasn’t feeling well that day. 那天她感到不太舒服。
