第十七讲       一般过去时 
 
一. 概念    
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。例句: 
1.I watched TV last night.
我昨天晚上看电视。 
 did you do yesterday?
你昨天做了什么? 
 went to Beijing last year.
他们去年去了北京。 
 
二.用法
1.表示过去发生的动作或状态,通常会有明确的表示过去的时间状语。 
      I
went to the zoo yesterday. 
      I stayed up
last night. 
2.叙述过去连续发生的动作或状态。 
   This
morning , I got up early , went out for a walk ,
then came back and cooked for my 
family .
3.表示过去某一段不确定的时间内发生的动作或状态。 
      He worked
in the store for 5 years. 
三.Be动词在一般过去时中的变化 
1. am
和is在一般过去时中变为was。(was not=wasn't) 
2.
are在一般过去时中变为were。(were not=weren't) 
3.
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。
 
四.句中没有be动词的一般过去时的句子 
1.否定句:didn't
+动词原形,如: 
Jim didn't go home yesterday.
2.一般疑问句:在句首加did,句子中的动词过去式变回原形。如: 
Did Jim
go home yesterday? 
3.特殊疑问句:疑问词+一般疑问句?如:
What did Jim do yesterday? 
五.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.末尾是辅
音字母加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 
六.真题再现 
(    ) 1. The
boy         the tree last week.   
A. is watering      B. waters    C. watered 
2.
I _____(see) his name in the newspaper yesterday.
因为句中出现了表示过去的时间状语last
week和yesterday,所以正确答案分别为:1. C
