一般过去时;;二、谓语动词的构成形式 一般过去时的谓语动词有be动词和行为动词两种基本形式。 类比一般现在时： （1）当谓语动词是be (am, is, are) 动词时，am/ is 变为was, are 变为were。在 否定句中，直接将not添加在was/ were之后. 疑问句时，将was/were置于主语之前即可。 e.g. 肯： I was ill yesterday morning. 否： I wasn’t ill yesterday. ;一般疑问句：——Were you ill yesterday morning? ——Yes, I was. /No, I wasn’t. 特殊疑问句：How was she？ （2）当谓语动词是行??动词时，将对应的一般现在时肯定句中的行为动词变成过去式；否定及疑问句中的do/does变成did即可动词仍用原形，即“见did，也用动原”。 一般现在时 一般过去时;规则过去式变化规律： ;写出下列动词的过去式 1. study ______ 2. go ____ 3. turn ______ 4. are____ 5. play ______ 6. have ____ 7. stop _______ 8. clean_______ 9. is ____ 10. love_____;三、一般过去时的用法 1.表示在过去时间里发生的动作或存在的状态 e.g. Liu Jie got up at 7: 10 this morning.
