五、根据提示，仿写句子或对话。

1. A: Can I help you?
B: Yes. I want five apples. How much are they?

2. A: Can I help you?
B: Yes. I want four hats. How much are they?
A: It's eighty-eight yuan.
3. A: Can I help you?
B: Yes. I want a clock. How much is it?

【分析】本题要求仿写购物场景的英语对话，需遵循示例结构：A以服务用语“Can I help you?”开头，B说明想要的物品及数量，再根据物品单复数用对应价格问句（复数物品用How much are they?，单数物品用How much is it?），A最后回答总价。解题时需先确定各小题的物品、数量、单价，结合单复数规则调整be动词，再对应写出价格。
【解析】1. 物品为苹果，数量5个（复数），单价4元，总价20元，按结构写出对应对话；2. 物品为帽子，数量4个（复数），单价22元，总价88元，按结构写出对应对话；3. 物品为闹钟，数量1个（单数），单价40元，按结构写出对应对话。
