【语法讲解】 一般过去时（II）
1．一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作。 2．Be动词在一般过去时中的变化：
⑴am 和is在一般过去时中变为was。（was not=wasn’t） ⑵are在一般过去时中变为were。（were not=weren’t）
⑶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放到句首。 3．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：
⑴疑问词+did+主语+动词原形？如： What did Jim do yesterday?
⑵疑问词当主语时：疑问词+动词过去式？如：Who went to home yesterday? 动词过去式变化规则：
