小学英语通常现在时讲解及练习
一、概念：表示在过去某个时间里所发生动作或存在状态。通常在句子里找到表示过去时间词或词组。如：yesterday，yesterdaymorning/ evening，theday before yesterday（前天），lastnight/week/ month/year，justnow（刚才），twodays ago，aweek ago，in1990 等。如：Iwent to bed at eleven last night. 昨晚我11：00睡觉。
二、动词通常过去时改变规则
1．通常在动词末尾加-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重读闭音节，应双写末尾辅音字母，再加-ed，如：stop-stopped，plan-planned,
prefer-preferred
4．以“辅音字母+y”结尾，变y为i，再加-ed，如：
study-studied5．小学阶段不规则动词通常过去时：
am/is→was are→were have/has→had do→did
sing→sang sit→sat come→came eat→ate
give→gave run→ran
take→took write→wrote ride→ rode drive→drove speak→spoke get→got
know→knew see→saw
teach→taught buy→bought
read→read put→put hurt→hurt cut→cut fall→fell say→said
三、句式改变
(1)Be 动词在通常过去时中改变
① am和is在通常过去时中变为was。（wasnot=wasn’t）
②are 在通常过去时中变为were。（werenot=weren’t）
③带有was或were句子，其否定、疑问改变和is,am, are 一样，即否定句在was或were后加not，通常疑问句把was或were调到句首。
(2)句中没有be动词通常过去时句子
Jimdoes homework every day.
Jimdid homework yesterday.
否定句：Jimdid homework yesterday.
Jimdidn't do homework yesterday. (didn't +动词原形)
通常疑问句：Jimdid homework yesterday.
DidJim do homework yesterday? (在句首加did，句子中动词过去式变回原形)
特殊疑问句：Jimdid homework yesterday.
DidJim do homework yesterday?
Whatdid Jim do yesterday? (疑问词+通常疑问
句？)
