我就是在考场上算阿算
最后选了C
数学做完只剩5分钟。头晕晕的。心想死定了。
结果出来果然也只有50

再补充两道数学jj
1.数轴上有三个点，分别用R，S，T表示。R在零点左边，S,T在零点右边。已知r,s,t表示R，S，T的绝对值，求R，S，T三个数的均值。
我选得是(s+t-r)/3
2.已知三个数R,S,T ,求这三个数的均值？
（1）（R+S+T）/2=某个数
（2）（R+S+T）/5=某个数
我选的是D
做这两道题时，我坚决相信自己掉进了低分库。
还有遇到的JJ，例如三个轮子，半径分别为2，4，6。小轮子转一又二分之一圈时，问其他两个大轮子的指针所指数的和是多少。因为当时自己算了一遍，所以答案记得很清楚是5。大家要是碰到了就直接选5阿。不要像我这么浪费时间。
还有选三明治的题，问最后有多少种配法。答案是24+12+12=48

Medallion systems

    

In some large American cities, as well as Hong Kong, a medallion system
is used to license cabs. The city issues a fixed number of medallions,
and only medallion taxis are allowed to pick up fares. In general, this
leads to medallions becoming ever more expensive -- a New York City
corporate medallion sells for more than $600,000. Medallions are
transferable, and while some cab drivers own their own medallion, most
must lease one on a daily or weekly basis from a fleet owner.

    

The medallion system has several effects upon the illegal transportation market. By acting as a barrier to entry
to the taxi market, it has the unintended consequence of creating a
market for unlicensed cabs, especially in areas that tend to be
underserved by medallion cabs. Taxi medallions tend to increase in
value over time, and their owners and leases tend to be very eager to
protect their exclusive rights, for example, by lobbying for stricter
enforcement against unlicensed cabs.
