初中英语语法基本时态讲与练

2010-05-27 11:12:56  来源:博客

  一般过去时主要表示过去某时发生的动作或情况。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。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?


  另外,还可用过去时表示委婉的语气。e.g. Could you lend me your pen?


  其结构是"主语+动词的过去式"。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.有些动词变过去式是不规则的,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?


  其时间状语为yesterday或由其构成的短语,e.g. yesterday morning; 由"last+时间"构成的短语, e.g. last year; 由"时间段+ago"构成的短语, e.g. three days ago; 另外,还有on the morning of Monday, just now等,以及一些表示过去时态的从句.注意,在宾语从句中主句为过去,一般从句也为过去.
