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和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。 

2. 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
