一般过去时态讲解与练习

一般过去时态讲解与练习 一般过去时主要表示过去某时发生的动作或情况。结构是“主语+动词的过去式”可以从以下几个方面来理解： 1、过去某个时间所发生的动作或存在的状态，句中有明确的表示过去的时间状语如：yesterday（昨天）, last night（昨晚）, last week（上个星期）, four days ago（四天前）, in 2002（在 2002 年）, just now（刚才）, the day before yesterday（前天）等。表示在过去某个时间发生的动作或情况。e.g. I bought a new shirt yesterday. He was a worker two years ago. 2、过去一段时间内，经常性或习惯性的动作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term. 3、谈到已故人的情况时多用过去时。e.g. Lu Xun was a great writer.4)有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去时态。e.g. What did you say? 动词过去式的构成： be 动词的过去式为 was, were;行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况： 1)直接在动词原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以 e 结尾的动词只加-d. e.g. arrive-----arrived; like-----liked. 3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shop-----shopped; 4) 以 " 辅 音 字 母 +y" 结尾 的动词 , 先 把 y 变 成 i, 再 加 -ed. e.g. carry----carried; study------studied. 不规则动词变过去式见同学们课本的最后一页,e.g. fly------flew; break-----broke; teach-----taught. 这些需要象生单词一样记住. 其句式变化分为两种情况： 1)含有 be 动词的依然在 be 上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加助动词 didn't.,同时把动词变成原形; 变一般疑问句,在句首加助动词 did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday? 课后练习 一、请写出下列动词的过去式。 want arrive enjoy shop is see are eat 二、 指出下列句中的一处错误，并改正。 1. W...
