第二个知识点：Mr.Cool's Clothes Store
1.Come and buy your clothes.
buy“买”
常用短语为：buy sb. sth./buy sth. for sb.
2.clothes指身上穿的各种服装,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。
Language Points（page.41)I often (买）gifts for my parents on their birthday.(2013南京）buy

on sale出售；廉价出售=at a great sale.
e.g.The sweaters in the store are on sale today. 今天这家商店的毛衣大减价了。

以非常便宜的价格, at 表示“以……的价格”。e.g.We have sweaters in all colors at ￥6 each! 我们所有颜色的毛衣都卖六元一件！
