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
