2018考研英語復習正在進行中，***老師的每日一句每年都很受關注，在長難句解析拆分句子的方法也講解得十分到位，新文道考研官網匯總了***2018考研英語每日一句，下面是***每日一句第207句。

也許對于大多數普通消費者來說，建議零售價和簡單折扣仍是商家的主流定價策略。但事實要遠比想象要復雜。目前許多經濟學家和數據科學家正利用互聯網經濟的規模和便利的試驗來制定更詳細更針對性的定價體制，(電腦模擬狀態下，數據試驗的成本會非常低。)只不過身為“小白鼠”的我們還懵懂未知。晚上7點前消費者是否愿意花更多的錢買一雙鞋?郊區居民愿意接受的價位是否不同于市區居民?為什么購物網站上同一件商品的價格和飛機票一樣總是在不斷變化?電商的定價團體利用在不同時點和針對不同分層的消費者顯示不同的價格，來收集更多的數據并根據結果流量來試出最能夠掏空消費者錢包的價格。雖然亞馬遜的相關人員辯解說，價格變化只是為了讓消費者享受最大優惠。

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.”

詞匯突破:

1.ample充足的

2.immense巨大的

3.data trail 數據足跡

4.register寄存器

5.capable有能力的

6.unparalleled無雙的;空前未有的

確定主干：

They have ample means to do so…

切分成分：

1.the immense data trail同位語(第一個方法)

2.(that) you leave behind定語從句

3.whenever you place something in your online shopping cart at a store register狀語從句

4.top economists and data scientists同位語(第二個方法)

5.(who are) capable of turning this information into useful price strategies定語從句

6.and what one tech economists calls “the ability to experiment on a scale that’s unparalleled in the history of economics.”同位語(第三種方法)

其中有一個定語從句： on a scale that’s unparalleled in the history of economics.

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

參考譯文：他們有充足的手段來做這件事：無論何時你把東西加入線上購物車，留在存儲寄存器中，都會在身后留下海量的數據足跡;頂尖的經濟學家和數據科學家有能力將這些信息轉化成實用的定價策略;還有一位技術經濟學家所稱的，“用經濟史上前所未有的規模進行試驗的能力”

明天的題目:

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 goals, obtaining immediate feedback and concentrating as much on technique as on outcome.(同學們只需要抄第一句就好了。)

1.According to Ericsson, good 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.
