()2. The shoes are 99 yuan.
()3. The hat is beautiful and cheap.

由于题目中未提供听力内容，无法直接判断句子的正误。请提供听力材料以便进行解答。
若假设存在听力材料，解题方法如下（符合四年级下册Unit 4 "Going shopping"内容，围绕物品价格、特征等关键词如expensive, cheap, beautiful, yuan等进行判断）：
1. 听关于太阳镜价格的描述，若提到"expensive"则T，否则F。
2. 听鞋子价格是否为99 yuan，是则T，否则F。
3. 听帽子是否被描述为"beautiful and cheap"，是则T，否则F。
4. 听衬衫是否被描述为"very beautiful"，是则T，否则F。
5. 听连衣裙是否被描述为"expensive"，是则T，否则F。
需根据听力内容判断各句描述是否与听到的信息一致。

三、Sherry和同学们都带来了一些物品，准备在跳蚤市场上售卖。阅读短文，补全表格信息。
Hi! I'm Sherry. I have a pretty dress. It's fifty yuan. I like it very much. Jane has an expensive hat. It's red. It's sixty-eight yuan. Sam has a pair of sunglasses. They are cheap. They are ten yuan. Bill has a pair of nice shoes. They're forty yuan.

1. dress；2. Jane；3. ¥68；4. sunglasses；5. Bill；6. shoes

1. 根据文中“I have a pretty dress.”可知Sherry卖的是dress；2. 由“Jane has an expensive hat.”可知第二空填Jane；3. 接着“ It's sixty-eight yuan.”得出帽子价格是¥68；4. 从“Sam has a pair of sunglasses.”可知Sam卖的是sunglasses；5. 由“Bill has a pair of nice shoes.”可知第五空填Bill；6. 最后“ They're forty yuan.”得出Bill卖的是shoes。
