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
