小学英语一般过去时讲义(1).doc

★一般过去时★
1、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，yesterday morning/ evening，the day before yesterday（前天），last night/week/ month/year，just now（刚才），two days ago，a week ago，in 1990等。
如：I went to bed at eleven last night. 昨晚我11：00睡觉。

2、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
5．小学阶段不规则动词一般过去时：
am/is→was are→were have/has→had do→did
sing→sang sit→sat give→gave run→ran come→came　 eat→ate
take→took 　write→wrote ride→ rode drive→drove speak→spoke　 get→got
go→went make→made know→knew see→saw teach→taught buy→bought
read→read put→put hurt→hurt cut→cut
fall→fell say→said

3、句式变化
(1) Be动词在一般过去时中的变化
1) am 和is在一般过去时中变为was。（was not=wasn’t）
2) are在一般过去时中变为were。（were not=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
Jim does homework every day.
Jim did homework yesterday.
否定句： Jim did homework yesterday.
Jim didn't do homework yesterday. (didn't +动词原形)
一般疑问句： Jim did homework yesterday.
Did Jim do homework yesterday? (在句首加did，句子中的动词过去式变回原形)
特殊疑问句： Jim did homework yesterday.
Did Jim do homework yesterday?
What did Jim do yesterday? (疑问词+一般疑问句？)
