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 .
I wasn’t in Shanghai last year .
Was you in Shanghai last year ?
He went to the park yesterday .
He didn’t go to the park yesterday ?
Did he go to the park yesterday ?

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。
