I watched a movie last night. (我昨晚看了一部电影。) She was a teacher ten years ago. (十年前她是一名老师。) They went to the park yesterday. (他们昨天去了公园。) 2. 否定句: 主语 + did not (didn't) + 动词原形 + 其他. (注意: 助动词 did 后,谓语动词要恢复原形!) I didn't watch TV last night. (我昨晚没看电视。) She was not (wasn't) a doctor. (她不是医生。)- be动词的否定直接加not They didn't go to school. (他们没去上学。) 3. 一般疑问句: Did + 主语 + 动词原形 + 其他? (注意: 助动词 Did 后,谓语动词要恢复原形!) Did you watch TV last night (你昨晚看电视了吗?) Yes, I did. / No, I didn't. Was she a doctor (她曾经是医生吗?)- be动词提前构成疑问句 Yes, she was. / No, she wasn't. Did they go to school (他们去上学了吗?) Yes, they did. / No, they didn't. 4. 特殊疑问句: 特殊疑问词 + 一般疑问句? What did you do last night (你昨晚做了什么?) Where did she go (她去了哪里?) When was he born (他是什么时候出生的?) Who took my book (谁拿了我的书?)- 疑问词who作主语时,视为第三人称单数,语序同肯定句。 四、 基本用法 1、表示过去某个时间发生的动作或存在的状态(常与过去时间状语连用)。 He bought a new car last month. (他上个月买了一辆新车。) Yesterday she was very happy. (昨天她很开心。) 2、表示过去经常或反复发生的动作(常与 often, always, every day 等连用)。 When I was a child, I often played football. (当我还是个孩子的时候,我经常踢足球。) He always went to work by bus. (他过去总是乘公交车上班。) 3、用在讲故事或叙述过去的经历时。 Once upon a time, there was a beautiful princess... (从前,有一位美丽的公主...) 五、 易错点与难点 1、忘记动词变过去式: 在肯定句中,最容易犯的错误就是忘记将动词变为过去式。 (×)I watch a movie yester ... ...
