一般过去时

3.2 一般过去时   

3.2.1 结构  

一般过去时用动词的过去式表示。  

基本结构 否定句 一般疑问句 
Be动词 was/ were+not  was或were提前,放于句首 
行为动词 didn’t+do(动词原形) Did+主语+do(动词原形) 

注: 

在一般过去时的句子中,谓语动词可分为两类:一类是be动词,其形式为was与第一、三人称单数连用,were与第二人称和复数人称的主语连用。凡是由be动词做谓语的句子,变否定句时,直接在其后加not,即wasn’t 或weren’t,变一般疑问句将was/ were放在句首,句末用问号。另一类谓语动词是由行为动词来充当,如stayed\went\visited等,这一类动词做谓语时,可与任何人称连用,句子变否定时,要在主语后面,动词的前面加didn’t,动词用原形;一般疑问句是把did提到句首,动词用原形。   

I was in Shanghai last year .

动词过去式的记忆口诀  动词一般过去时, 表示过去发生事;be用was或用were, have, has变had; 谓语动词过去式, 过去时间坐标志;一般动词加- ed, 若是特殊得硬记。 否定句很简单, 主语之后didn’t添;疑问句也不难, did放在主语前;  如果谓语之前有did, 谓语动词需还原;动词若是was, were, 否定就把not添。
