  一般过去时

  1.一般过去时表示过去某个时间发生的动作或存在的状态,常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作感谢。

  2.Be动词在一般过去时中的变化:

  ⑴am 和is在一般过去时中变为was。(was not=wasn’t)

  ⑵are在一般过去时中变为were。(were not=weren’t)

  ⑶带有was或were的句子,其否定、疑问的变化和is, am, are一样,即否定句在was或were后加not,一般疑问句把was或were调到句首。

  3.句中没有be动词的一般过去时的句子

  否定句:didn’t +动词原形,如:Jim didn’t go home yesterday.

  一般疑问句:在句首加did,句子中的动词过去式变回原形。

  如:Did Jim go home yesterday?

  特殊疑问句:⑴疑问词+did+主语+动词原形?

  如: What did Jim do yesterday?

  ⑵疑问词当主语时:疑问词+动词过去式?

  如:Who went to home yesterday?

  动词过去式变化规则:

  1.一般在动词末尾加-ed,如:pull-pulled, cook-cooked

  2.结尾是e加d,如:taste-tasted

  3.末尾只有一个元音字母和一个辅音字母的重读闭音节,应双写末尾的辅音字母,再加-ed,如:stop-stopped

  4.以“辅音字母+y”结尾的,变y为i, 再加-ed,如:study-studied
