新概念英语第一册语法:一般过去时

 来源:沪江英语    要点:新概念英语  
编辑点评: 一般过去时表示过去发生的动作或事件,常和表示过去的时间状语连用,如yesterday, last night, the day before yesterday, 3 days ago...

 ★特殊疑问句

  What did you do?(必背)

  不含有be动词的句子,将动词变为过去式:

  I finished my homework yesterday.

  The boy went to a restaurant.

  The Sawyers lived at King Street a year ago.

  ★变疑问句在句首加did,动词变为原型

  Did you finish your homework yesterday?

  Did the boy go to a restaurant?

  Did the Sawyers live at King Street a year ago?

  ★变否定句在主语和动词之间加did not

  I did not finish my homework yesterday.

  The boy did not go to a restaurant.

  The Sawyers did not live at King Street a year ago.

  ★肯定回答及否定回答
