一般过去时总结
这几天,我们在朗文书第十五课,学习了一种新的grammar(语法):past tense(一般过去时)。下面是我总结复习的内容:
一、定义:
一般过去时表示已经发生过的动作或存在的状态。常与表示过去的时间状语连用。例yesterday / last week / last month / last year / the day before yesterday…
二、 Exercise(练习)下面是妈妈出题,我来练习。
1、昨天上午你在擦车。
译: You washed your car yesterday afternoon.
对划线部分提问:What did you wash yesterday afternoon?
变否定句:You did not wash your car yesterday afternoon.
变一般疑问句:Did you wash your car yesterday afternoon?
肯定回答:Yes,I did. 否定回答:No, I didn’t.
2、前天上午他在学习。
译:He studied the day before yesterday morning.
对划线部分提问:What did he do before yesterday morning?
变否定句:He did not study the day before yesterday morning.
变一般疑问句Did he study the day before yesterday morning?肯定回答:yes, he did.否定回答:No, he didn’t.
3、昨天天很冷。
译:It was cold yesterday.
对划线部分提问:When was it cold?
变否定句:It was not cold yesterday.
变一般疑问句:Was it cold yesterday?
肯定回答:Yes, it was.否定回答:No, it wasn’t.
4、上周末你在家里。
译:You were at home last weekend.
对划线部分提问:where were you last weekend?
变否定句:You were not at home last weekend.
变一般疑问句:were you at home last weekend?
肯定回答:Yes, I was.否定回答:No, I wasn’t.
三、动词过去式的变化规律分为规则和不规则的。
规则的:1、一般的动词直接加ed,如:cook-cooked wash-washed…… 2、以e结尾的动词直接加d,如:shave-shaved smile-smiled…… 3、以辅音字母加y结尾的,变y为i再加ed,如:cry-cried study-studied……
常见不规则的:buy-bought eat-ate go-went meet-met steal-stole do-did forget-forgot have-had read-read take-took drive-drove get-got make- made see-saw write-wrote is/am-was are-were……
(这些不规则动词过去式是要求我们熟记)
好了,以上就是我总结的,不知道对各位小博友有没有帮助,还有更深的知识,等以后慢慢学习。(呵呵,我只知道这些!
5555……)
妈妈的话:孩子,总结一下等于很系统的复习一遍,不管学习哪个学科,总结是非常有必要的。它可以让你学到的知识在脑子里更条理、更清晰,同时总结还可以让一些模棱两可、容易混淆模糊的知识点,重新区分对比。希望你以后学习,要经常做出各个学科总结。-----永远爱你的妈妈
