动词一般过去时,表示过去发生的事; 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。
• 一过去时时有两种形式: • 1.系动词be的一般过去时的形式:was(am, is), were(are) • was用于第一人称单数和第三人称单数形式的主语之后; • were用于所有其他的人称和数。 例句: He was born in 1997. There were many mice in that room. I was so tired. • 2.实意动词过去式的形式:did(do), stopped(stop), finished(finish), studied(study), hoped(hope) 例句:She studied very hard to go to the college. They didn’t hope that the car stopped.

But yesterday he didn’t read the newspaper. 5. I usually go shopping on weekends. But this weekend __________________________
• 一.改错
• 1. He watch TV here ten minutes ago. 他十分钟前在这里看电视。 watch在这这个动作是十分钟前发生的,属于过去时,所以 动词里是错误的,我们要把它改成过去式watched。 。2. They didn’t played basketball yesterday. 昨天,他们没有打篮球。 陈述句的否定形式借助助动词did 后,动词过去式played要 还原成动词原行play.
