Day 3 1. 水泥木头房子
The question said that there are two houses:cement水泥 and wood. Cement houses are likely to generate more cost savings in termsof cooling/heating compared to wood houses. Conducted experiment and confirmed.Argument says that cost savings will be more in real life compared to theexperiment. Ask to strengthen. 一般加强 猜测: 1.原理:为什么more in reallife? —experience和real life的difference-极端天气,毕竟气温是不能准确预测的;现实中,更能让凸显cement houses的cooling and heating效果 —cement houses在其他方面还能generate cost savings 2.表现:有代表性案例表明确实是more in reallife 2. 办信用卡防贼
学生之前往往用现金买饭,学校准备推出信用卡来防贼,这种信用卡会有学生的签名和头像,所以食堂里的员工可以辨认出学生来,减少贼。But this measure will not work, why? explain 猜测: 1.食堂人多,员工忙碌的时候,辨认比较快,不能准确辨认。 2.和持卡者本人长得相似的人难以通过肉眼辨认 3.有很多消费是通过电子设备购买的,不需要辨认人像,小偷到没有人工服务的地方进行消费 4.信用卡推行起来有困难,使用信用卡的人数不多 5.照片和签名很容易修改 3. 广告牌
Environmentalist say that 比较(不友好)的billboards andcommercial signs will reduce the increase of tourism. So government should banthose billboards and signs. But two states – vemon and maine -- whosegovernment banned the sign experienced a reduction in tourism growth. Explainwhy? 选项: A: Did not consider effects from othersigns
B: Did not consider factors other than the bansthat may affect the tourism growth explain B:可能有其他的因素reducethe increase of tourism的程度比比较不友好的signs造成的程度更深,所以即便ban signs,但是没有解决这些因素,仍然会reduce,考虑更全面
