课前自学

一、当我们谈论过去的事情时，我们用一般过去时。大家是否观察到动词在过去时中的变化呢？

1.你所理解的一般过去时，举例说明：

____________________________________________________

____________________________________________________

____________________________________________________

2.这些词想变身，你能把他们变成-ed形式吗？

search__________   answer__________   play__________

kick__________     love­__________      carry__________

start__________     use__________       chat__________

stop___________   shop____________ plan____________

◆回头看看你所变化后的词尾，你发现规律了吗？

___________________+ed,如：walk________

_________________+d,如：move________

___________________-y+ied,如：study_______

___________________双写_________+ed,如：stop________

◆动词过去式的变化并不都是规则的，也有不规则的，看：

不改变，如：cost ---cost    put---- put   let---let

改变元音字母，如：come-- came   write --wrote  ring--rang   know –knew

改变辅音字母，如：make-- made spend --spent   send --sent   build—built

改变元音和辅音字母，如：do--did  see---saw  have--had    find---found

 二、刚才的不规则动词过去式变化你都记住了吗？挑战一下吧

go_________    get_________      give_________ take_________

spend_________   see_________   have_________    tell_________

做好了吗？赶快完成P67 Part A2

四、行为动词过去时的否定句和一般疑问句是如何构成的呢？Can you work out the rule?

否定句：______+动词原形…,did not = ___________

一般疑问句：_______+ （主语）+动词原形…?

Yes,主语+_______ /No,主语+_______

理解吗？来实践一下吧，打开书P67，完成part A3 Millie 和Daniel的对话

一般过去时的用法：

    He was there just now.

    Where did you live when you were young?

 b. 也可以表示过去某一段时间内经常或反复出现的动作。句子中常带有every day, often, usually, always, sometimes 等时间状语。

如：When I studied in the university, I read aloud every morning.

在过去的几年里，每逢暑假我总是出去旅游。

 c. 也可以用“used to +动词原形”表示过去经常或反复的动作。
