Iwasdoingmyhomeworkatthistimeyesterday.昨天的这个时候我正在做作业。

Theywerewaitingforyouyesterday.他们昨天一直在等你。

过去进行时的构成：肯定形式：主语+was/were+V-ing否定形式：主语+wasnot(wasn't)/werenot(weren't)+V-ing疑问形式：Was/Were+主语+V-ing。基本用法：1.过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有，atthattime/moment,(at)thistimeyesterday(lastnight/Sunday/week…),at+点钟+yesterday(lastnight/Sunday…)，whensb.didsth等时间状语从句，如：

Whatwereyoudoingat.yesterday?昨天晚上七点你在干什么？

IfirstmetMarythreeyearsago.Shewasworkingataradioshopatthetime.我第一次遇到玛丽是在三年前，当时她在一家无线电商店工作。

Iwascookingwhensheknockedatthedoor.她敲门时我正在做饭。

2.when后通常用表示暂短性动词，while后通常用表示持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，如：

WhenthecarexplodedIwaswalkingpastit.=WhileIwaswalkingpastthecaritexploded.

用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。如：

Iwaswalkinginthestreetwhensomeonecalledme.我正在街上走时突然有人喊我。

4.when作并列连词，表示“（这时）突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。如：
