Task 2: 读关于自行车的场景对话，选择方框中的句子，将其英文大写字母编号填写在横线上，完成 Linda 家购买自行车的决策树。（有一个多余选项）
A. Don't buy it. / Look for a better deal. B. Do I really need it?
C. Is it before the BBD? D. Is it safe and comfortable?
E. Can I get it cheaper?

Task 3: 判断 Linda 和她的父母是否为理性的消费者，在括号内圈出你的选择，再列举理由。
I think Linda's family (were/weren't) smart buyers, because they

Task 2: (1) B (2) D (3) E (4) A
Task 3: I think Linda's family (were/weren't) smart buyers, because they only bought what they really needed and they waited for a better deal. They also compared and chose things. They tried things out.
(答案不唯一，合理即可)

【分析】
首先梳理购物决策树的逻辑：第一步需明确购买的前提——是否真的需要商品，对应选项B；接着判断是否为最优交易，若为最优交易，需进一步考量商品的安全与舒适度，对应选项D；之后确认能否获得更优惠的价格，对应选项E；若以上条件均满足则购买，不满足则选择不购买或寻找更优方案，对应选项A。Task3需结合上述决策过程，判断是否为理性消费者并阐述理由。
【解析】
Task2：根据购物决策的逻辑顺序，(1)处应先判断是否真的需要，选B；(2)处需考量商品的安全与舒适度，选D；(3)处确认能否获得更优惠的价格，选E；(4)处对应不满足条件的结果，选A。Task3：Linda家的决策过程符合理性消费，他们先确认自身需求，再判断交易是否最优，还考虑了价格、舒适度等因素，因此是理性买家，理由围绕需求、比价等合理阐述即可。
【答案】
Task 2: (1) B (2) D (3) E (4) A；Task 3: I think Linda's family (were) smart buyers, because they only bought what they really needed and they waited for a better deal. They also compared and chose things. They tried things out.
【知识点】
购物决策、理性消费
【点评】
本题以决策树形式考查购物时的理性消费逻辑，需结合生活常识和逻辑顺序匹配选项，Task3需结合决策过程分析，整体难度适中。
