Be动词的一般过去时
内容在没有实义动词的句子中使用be动词,am / is 的过去式为was; are的过去式为were
肯定句式：主语 + be(was , were) + 其它.
I was late yesterday. 我昨天迟到了。
否定句式：主语 + be(was , were) + not + 其它.
We weren't late yesterday. 我们昨天没有迟到。
一般疑问句：Be(was , were) + 主语 + 其它？
Were you sick yesterday 你昨天病了吗？
肯定回答：Yes,I was. （是的，我病了。） 否定回答：No,I wasn't. （不，我没病。）
注：在这种构成中，be动词有人称和数的变化，即要根据主语选用was / were。Be动词分为单数和复数，was是表示单数，were是表示复数。
实义动词的一般过去时态
注：
1.实意动词do的一般过去时 ( do-did does-did )
2. did和didn’t是构成一般过去时的助动词，其特点是要在其后跟动词的原形。
肯定句要使用动词的过去式，否定句和疑问句要使用助动词do和 does 的过去式 did.
肯定句式：主语 + 动词（过去式）+ 其它
