Some important 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) 2129 直到9199，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.强化巩固1.
