20.Before birth,babies can tell the difference between loud sounds and voices.They can even distinguish their mother's voice from that of a female stranger.But when it comes to embryonic learning(胎教),birds could rule the roost.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.This educational method was first observed in 2012 by Sonia Kieindorfer,a biologist at Flinders University in South Australia,and her colleagues.Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs,When the eggs were hatched,the baby birds made the similar chirp to their mothers-a sound that served as their regular"feed me!"call.
To find out if the special quality was more widespread in birds,the researchers sought the red-backed fairy wren,another species of Australian songbird.First they collected sound data from 67 nests in four sites in Queenslang before and after hatching,Then they identified begging calls by analyzing the order and number of notes.A computer analysis blindly compared calls produced by mothers and chicks,ranking them by similarity.
It turns out that baby red-backed fairy wrens also emerge chirping like their moms.And the more frequently mothers had called to their eggs,the more similar were the babies'begging calls.In addition,the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom's voice were rewarded with the most food.
This observation hints that effective embryonic learning could signal neurological(神经系统的)strengths of children to parents.An evolutionary inference can then be drawn."As a parent,do you invest in quality children,or do you invest in children that are in need?"Kleindorfer asks."Our results suggest that they might be going for quality."
58.The underlined phrase in Paragraph 1 means"B".
A.be the worst B.be the best
C.be the as bad D.be just as good
59.What are Kleindorfer's findings based on?A
A.Similarities between the calls moms and chicks.
B.The observation of fairy wrens across Australia.
C.The data collected from Queensland's locals.
D.Controlled experiments on wrens and other birds.
60.Embryonic learning helps mother birds to identify the baby birds whichC.
A.can receive quality signals
B.are in need of training
C.fit the environment better
D.make the loudest call.
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.
60.C 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.
