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 terms of cooling/heating compared to wood houses. Conducted experiment and confirmed. Argument says that cost savings will be more in real life compared to the experiment. Ask to strengthen.
现实中环境温度变化更大,更放大了水泥保温的省钱作用

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?
食堂员工没用时间看

3. 广告牌
Environmentalist say that 比较(不友好)的billboards and commercial signs will reduce the increase of tourism. So government should ban those billboards and signs. But two states – vemon and maine -- whose government banned the sign experienced a reduction in tourism growth. Explain why?
A: Did not consider effects from other signs
B: Did not consider factors other than the bans that may affect the tourism growth -->影响旅游增长的因素很多 |
