三 语法点

过去式(1) Be动词型

概念:表示过去某时间发生的事,存在的状态或过去反复(习惯)发生的动作 be型句子(也就是am, is ,are在句子里做动词的句子) am, is → was are → were

体会: He was a student 2 years ago, now he is a worker.

I often got up at six 2 years ago. 我两年前通常在六点起床。（过去习惯性做的动作)

( I often get up at six in the morning. 现在习惯性做的动作) (体会: 通过Be动词的变化来体现过去式的意思)

句子转换: My camera was on the desk just now. → My camera was not on the desk just now.

(我的照相机刚才在课桌上。） （我的照相机刚才不在课桌上）

Was your camera on the desk just now?→ Where was your camera just now?

（你的照相机刚才在课桌上吗？） （你的照相机刚才在哪儿）
