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