过去进行时与一般过去时的区别一

一、 时间状语不同一般过去时的时间状语主要有：yesterday (morning, afternoon, evening), last night (week, month, year), ago, the day before yesterday, in 2003, just now, long long ago, one day等;过去进行时的时间状语有：at this / that time yesterday, the whole evening, all day yesterday等。

试比较：

He introduced Tom to us just now.刚才他向我们介绍了汤姆。She was doing some washing all day yesterday.昨天她洗了一整天的衣服。
