一般过去时的构成
一般过去时由规则动词(-ed/-d)或不规则动词的过去时表示，除be动词外，其余动词没有人称和数的变化。各种动词的否定结构和一般疑问结构，与一般现在时的否定结构和疑问结构相同。
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)

句中没有be动词的一般过去时的句子
●否定句：didn't +动词原形，如：Jim didn't go home yesterday.
●一般疑问句：在句首加did,句子中的动词过去式变回原形。
如：Did Jim go home yesterday.
●特殊疑问句：
（1）疑问词+did+主语+动词原形
如：What did Jim do yesterday.
（2）疑问词当主语时：疑问词+动词过去式
如: Who went to home yesterday.
