AA是:改善校园住宅使用率低的问题 “Because occupancy rates for campus housing fell during the last academic year, so did housing revenues. To solve the problem, campus housing officials should reduce the number of available housing units, thereby increasing the occupancy rates. Also, to keep students from choosing to live off-campus, housing officials should lower the rents, thereby increasing demand.” 思路,供参考: 1, all things are equal——去年的fell不能代表今年 2, false casual relationship——价格降低不一定increase demand,有其他因素会影响,比如location啊,房子质量啊周围环境啊服务啊 3, 即使需求增加也不一定revenue增加,要证明需求增加带来的profit不会被价格的降低所抵消
AI是:one can stuty effectively more depends on others in the classroom than the quality of teacher 思路,供参考: 1, classmates会影响学生的学习心态,班级的氛围对学习效率有很大影响 2, excellent classmates在一些teamwork中尤其重要,比如group discussion,和优秀同学一起合作会效率更高,也会被inspired 3, 当然,老师也很重要,但是同学每天一起相处,对学生的整体learning experience影响更大
