【考点】O5：科教类阅读．菁优网版权所有
【分析】本文是一篇科教类阅读，文章主要介绍鸟类在胎教方面可以称第一，有些鸟妈
妈会教它们的孩子叫，甚至在它们孵化的过程中．有效地胚胎学习可以向鸟妈妈告知它
们孩子的神经系统得到加强．
【解答】58．B 词义辨析题．根据第二段As recently reported in The Auk：Ornithological
Adrances，some mother birds may teach their young to sing even before they hatch（孵
化） ．New﹣born chicks can then imitate their mom's call within a few days of enering the
world．可知海雀近日报道：有些鸟妈妈会教它们的孩子叫，甚至在它们孵化的过程
中． 新出生的小鸡就可以模仿它们的妈妈叫声． 由此可知，But when it comes to embryonic

learning（胎教） ，birds could rule the roost． 的意思是：说到胎教， 鸟类可以称第一． 即"rule
the roost"的意思是：最好的．故选B．
59．A 理解判断题．根据第二段""可知，研究发现是对澳大利亚两种会鸟鸣的鸟儿进行
了记录，根据第三段"the researchers sought the red﹣backed fairy wren，another species of
Australian songbird．"可知，研究人员并未在全澳洲范围展开调查；未对其它鸟类进行记
录研究，排除BD项．根据倒数第三段"A computer analysis blindlycompared calls produced
by mothers and chicks，ranking them by similarity．"可知，故选A．

【答案】C

【解析】细节理解题．根据倒数第二段"the baby birds that mostclosely imitated their mom's
voice were rewarded with the most food"和最后一段"Our results suggest that they might be
going for quality．"可知，模仿母鸟模仿得最好的雏鸟得到最多的食物，研究结果表明，
母亲会选择质量好的雏鸟、孩子，即能比较好地适应环境的孩子．故选C．
【点评】本文考察学生的理解推断能力以及细心程度，只要抓住文章的关键词，采用寻
读的方法查找细节，就能找到正确答案．
29． （8分）A new commodity brings about a highly profitable，fast﹣growing industry，urging
antitrust（反垄断）regulators to step in to check those who control its flow．A century ago，
the resource in question was oil．Now similar concerns are being raised by the giants（巨头）
that deal in data，the oil of the digital age．The most valuable firms are Googole，Amazon，
Facebook and Microsoft．All look unstoppable．
Such situations have led to calls for the tech giants to be broken up．But size alone is not
a crime，The giants'success has benefited consumers．Few want to live without search engines
or a quick delivery，Far from charging consumers high prices，many of these services are free
（users pay，in effect，by handing over yet more data） ．And the appearance of new﹣born
giants suggests that newcomers can make waves，too．
But there is cause for concern．The internet has made data abundant，all﹣present and far
more valuable，changing the nature of data and competition．Google initially used the data
collected from users to target advertising better．But recently it has discovered that data can be
turned into new services：translation and visual recognition，to be sold to other
companies．Internet companies'control of data gives them enormous power．So they have
a"God's eye view"of activities in their own markets and beyond．
This nature of data makes the antitrust measures of the past less useful．Breaking up firms

like Google into five small ones would not stop remaking themselves：in time，one of them
would become great again．A rethink is required﹣and as a new approach starts to become
apparent，two ideas stand out．
The first is that antitrust authorities need to move form the industrial age into the 21st
century．When considering a merger（兼并） ，for example，they have traditionally used size
to determine when to step in．They now need to take into account the extent of firms'data assets
（资产） when assessing the impact of deals．The purchase price could also be a signal that an
established company is buying a new﹣borm threat．When this takes place，especially when a
new﹣born company has no revenue to speak of，the regulators should raise red flags．
The second principle is to loosen the control that providers of on﹣line services have over
data and give more to those who supply them．Companies could be forced to consumers what
information they hold and how much money they make from it．Governments could order the
sharing of certain kinds of data，with users'consent．
Restarting antitrust for the information age will not be easy．But if governments don't wants
a data oconomy by a few giants，they must act soon．
