Ask and answer questions about the things in the picture above.

Role-play
They are eighteen dollars.
1. 基数词表达
1) one到twelve，拼写和读音无规律。
2) thirteen到nineteen, “十几”, 在个位数后加后缀-teen, 注意thirteen, fifteen和eighteen。
3) twenty到ninety, “几十”, 以ty结尾, 注意twenty, thirty, forty, fifty, eighty。
Language points
4) 21~29直到91~99, “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 “一百”, 也可说 a hundred, 可加具体数字, 如nine hundred (900)。此时, hundred要用单数。
2. 基数词用法
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：
一名学生 one student
两名男孩 two boys
二十个苹果 twenty apples
三十三个鸡蛋 thirty-three eggs
