也许对于大多数普通消费者来说，建议零售价和简单折扣仍是商家的主流定价策略。但事实要远比想象要复杂。目前许多经济学家和数据科学家正利用互联网经济的规模和便利的试验来制定更详细更针对性的定价体制，(电脑模拟状态下，数据试验的成本会非常低。)只不过身为“小白鼠”的我们还懵懂未知。晚上7点前消费者是否愿意花更多的钱买一双鞋?郊区居民愿意接受的价位是否不同于市区居民?为什么购物网站上同一件商品的价格和飞机票一样总是在不断变化?电商的定价团体利用在不同时点和针对不同分层的消费者显示不同的价格，来收集更多的数据并根据结果流量来试出最能够掏空消费者钱包的价格。虽然亚马逊的相关人员辩解说，价格变化只是为了让消费者享受最大优惠。

They have ample means to do so: the immense data trail you leave behind whenever you place something in your online shopping cart at a store register, top economists and data scientists capable of turning this information into useful price strategies, and what one tech economists calls “the ability to experiment on a scale that’s unparalleled in the history of economics.”

词汇突破:

1.ample充足的

2.immense巨大的

3.data trail 数据足迹

4.register寄存器

5.capable有能力的

6.unparalleled无双的;空前未有的

3.whenever you place something in your online shopping cart at a store register状语从句

4.top economists and data scientists同位语(第二个方法)

5.(who are) capable of turning this information into useful price strategies定语从句

6.and what one tech economists calls “the ability to experiment on a scale that’s unparalleled in the history of economics.”同位语(第三种方法)

其中有一个定语从句： on a scale that’s unparalleled in the history of economics.

其中that= scale; = The scale is unparalleled in the history of economics.

参考译文：他们有充足的手段来做这件事：无论何时你把东西加入线上购物车，留在存储寄存器中，都会在身后留下海量的数据足迹;顶尖的经济学家和数据科学家有能力将这些信息转化成实用的定价策略;还有一位技术经济学家所称的，“用经济史上前所未有的规模进行试验的能力”

明天的题目:

This success, coupled with later research showing that memory itself is not genetically determined, led Ericsson to conclude that the act of memorizing is more of a cognitive exercise than an intuitive one. In other words, whatever inborn differences two people may exhibit in their abilities to memorize, those differences are swamped by how well each person “encodes” the information. And the best way to learn how to encode information meaningfully, Ericsson determined, was a process known as deliberate practice. Deliberate practice entails more than simply repeating a task. Rather, it involves setting specific als, obtaining immediate feedback and concentrating as much on technique as on outcome.(同学们只需要抄第一句就好了。)

1.According to Ericsson, od memory

[A] depends on meaningful processing of information.

[B] results from intuitive rather than cognitive exercises.

[C] is determined by genetic rather than psychological factors.

[D] requires immediate feedback and a high degree of concentration.
