一般过去时
一、概念：表示在过去某个时间里所发生的动作或存在的状态。通常在句子里找到表示过去时间的词或词组。如：yesterday，yesterdaymorning/evening，thedaybeforeyesterday（前天），lastnight/week/month/year，justnow（刚才），twodaysago，aweekago，in1990等。如：Iwenttobedatelevenlastnight.昨晚我11：00睡觉。
二、动词一般过去时变化规则
1．一般在动词末尾加-ed，如：pull-pulled,cook-cooked,play-played
2．结尾是e加d，如：taste-tasted
3．末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，如：stop-stopped，plan-planned,prefer-preferred
4．以“辅音字母+y”结尾的，变y为i，再加-ed，如：study-studied
三、句式变化
(1)Be动词在一般过去时中的变化
①am和is在一般过去时中变为was。（wasnot=wasn’t）
②are在一般过去时中变为were。（werenot=weren’t）
③带有was或were的句子，其否定、疑问的变化和is,am,are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。
(2)句中没有be动词的一般过去时的句子
Jimdoeshomeworkeveryday.
Jimdidhomeworkyesterday.
否定句：Jimdidhomeworkyesterday.
Jimdidn'tdohomeworkyesterday.(didn't+动词原形)
一般疑问句：Jimdidhomeworkyesterday.
DidJimdohomeworkyesterday?(在句首加did，句子中的动词过去式变回原形)
特殊疑问句：Jimdidhomeworkyesterday.
DidJimdohomeworkyesterday?
WhatdidJimdoyesterday?(疑问词+一般疑问句？)
