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 yu?”。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 ne，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。

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) ne 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：ne student 一名学生 tw bys 两名男孩twenty apples 二十个苹果 thirty-three eggs 三十三个鸡蛋
