Unit 7 How much are these socks ?

(SectionB1a-1e)学案

【预习】

参阅教材88页，试着写一写下列数字并总结规律。

 【探究】

一、基数词

一、英文数字写法的规律:   

1. 基数词的表达
1) one到twelve, 拼写和读音无规律可言, 只能逐一记忆。
2) thirteen到nineteen，表示“十几”，在个位数后加后缀-teen，其中要注意thirteen,fifteen, eighteen的拼写。                                                         

3) twenty到ninety，表示“几十”，以ty结尾，但需注意twenty, thirty, forty, fifty, eighty的拼写。

4) 21~29 直到91~99，表示“几十几”,用整十位数加个位表示, 中间用连字符“-” 把十位和个位连接起来twenty-five, twenty-nine, thirty-three。                                       

one hundred 意为 “一百”，也可说a hundred，hundred可加具体数字，如nine hundred (900)。                                                                             

二、基数词的用法：
基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。           

  如：one student  一名学生       two boys 两名男孩
      twenty apples  二十个苹果   thirty-three eggs 三十三个鸡蛋 

总结：读一读数字的记忆规律（组内成员大声齐读）。

英语数词不难记，找出规律就容易。零至十二样各异，一个一个单独记，后加teen变十几，thirteen, fifteen看仔细，eight原本就有t。几十后面加ty，twenty不同重点记，forty去掉字母u，thirty, fifty更出奇。若要表示几十几，连字符号记清楚。更多表示几百几，and来把百、十系。
