小学六年级英语 一般过去时.doc

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=wasnt） 2. are在一般过去时中变为were。（were not=werent） 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：didnt +动词原形，如： Jim didnt 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 2.saw 精点精练 一、用动词的适当形式填空。 1. It __________ (be) Bens birthday last Friday. 2. We all __________ (have) a good time last night. 3. He __________ (jump) high on last Sports Day. 4.
