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。 2.What did you do yesterday?
你昨天做了什么？ 3.They 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 boythe 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 2.saw
