I was not born in 1980.? Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加助动词didnt.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday.? I didnt buy a gift for my mum yesterday.? Did you buy a gift for your mum yesterday? 一般过去式的用法： ? 　1) 表示过去某一时刻或某一段时间内所发生的动作或情况，通常一般过去式带有表示动作时间状语的词，词组或从句,如：a minute ago, yesterday,last week,in1900,during the night,in those days，the other day
