一般过去时的用法(一般过去时知识点讲授)

一.概述

一般过去时表现过去某个时光产生的动作或状况,常和表现过去的时光连用,yesterday, last night, in 1990, two days ago等。也表现过去经常或重复产生的动作,常和often, always等表现频度的时光状语连用。

二.一般过去时的构成

一般过去时由规矩动词(-ed/-d)或不规矩动词的过去时表现,除be外,其余动词没有人称和数的变更。各种动词的否认构造和一般疑问构造,与一般现在时的否认构造和疑问构造雷同。

三.Be动词在一般过去时中的变更:

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,其否认、疑问的变更和is, am, ar百思特网e一样,即否认句在was或were后加not,一般疑问句把was或were调到句首。

否认句:didn’t +动词本相,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本相。

如:Did Jim go home yesterday?

特别疑问句:

⑴疑问词+did+主语+动词本相?

如: What did Jim do yesterday?

⑵疑问词当主语(原创www.isoyu.com版权)时:疑问词+动词过去式?

如:Who went to home yesterday?

①一般在动词末尾加-ed,如:play-played, cook-cooked

②结尾是e加d,如:like-liked love-loved

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
