twenty-eight _______.

阅读指导：
首先，快速阅读对话一遍，明确自己售货员的身份，可知第一句话应为“Can I help you?”。
然后，读对话，通过对话中谈到的衣物的颜色或价格等信息来确定是何衣物；或通过所谈到的衣物来填写其颜色或价格。
如在女孩购物的情境中，根据所谈到these red and purple one，再与短文中的“We have skirt in red and purple”信息相对应，可知女孩是想买短裙，价格是$20。
男孩谈到需要一双棕色的某物上学穿，再由下文知其仅是28美元，回顾短文可知所谈应是鞋子。男孩还谈到了要买短裤，对应短文内容可知短裤的价格是16美元。
Answers: can, skirt, skirts, much, 20, take, shoes, only, dollars, 16, shoes, shorts

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
3. Come and buy your clothes at our great
sale! 我们在大甩卖，快来买衣服吧！
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”。
e.g. Let’s buy mom a new sweater. （= Let’s buy a new sweater for mom.） 我们给妈妈买件新毛衣吧。
clothes指身上穿的各种服装，包括上衣，内衣，裤子等，是衣服的总称。它不能直接与数词连用，但可以与some, many, these或those等连用。
e.g. Look! Some clothes are on sale over
there. 看！那边的衣服大减价了。
sale是动词sell的名词形式，常用短语：
on sale，意为“廉价出售”，其同
义短语为at great sale。
e.g. The sweaters are on sale /at great sale today.
今天毛衣大减价了。
5. We sell all our clothes at very good prices.
我们卖的所有服装价格都很实惠。
at very good prices意为“以合理的价格
(出售)”。price用作名词，意为 “价格”。
e.g. 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美元。
6. For girls, we have skirts in purple for only＄20.
对于女孩，我们有紫色的裙子，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……”。
e.g. The girl in red is my sister.  那个穿红衣服的女孩是我妹妹。
