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3. buy用作动词，意为“买”，常用短语为：buy sb. sth./buy sth. for sb.意为“给某人买某物”。如：
Let’s buy mom a new hat. （=Let’s buy a new hat for mom.） 我们给妈妈买顶新帽子吧。 7. at very good prices意为“以合理的价格(出售)”。price用作名词，意为 “价格”。如：
What’s the price of the book? 这本书多少钱?
They have sweaters in all colors, at the price of＄15 each. 他们有各种颜色的毛衣，每件售价是15元。8. For girls, we have skirts in red and purple for only＄20. 对于女孩，我们有红色和紫色的裙子，仅售20元。
1) for girls中的for是“对于……而言”；for only＄20中的for是“交换”的意思。
2) 该句中的 in 后接颜色的词，表示“穿……颜色的……”。如：
The girl in red is my sister. 那个穿红衣服的女孩是我妹妹。 一、填表格，记数字。 eleven 13fifteen12twenty16eighteen19thirtytwenty-six21twenty-eight35thirty-nineExercises 二、做数学题，学英语。
