Some birds, for example, flee when neighbors make a loud noise to announce a snakes presence.The fairy wren (细毛鹩莺) is a small Australian song
18、bird.It is not born knowing the “languages” of other birds. But recent research says it can learn the meaning of a few important sounds. Andrew N Radford is a biologist at the University of Bristol in England and co-writer of the new report published in early August in the journal Current Biology. H
19、e told the Associated Press, “We knew before that some animals can translate the meanings of other species foreign languages but we did not know how that language learning came about.”Birds have several ways of learning life skills. Some knowledge is genetically passed down by their parents and some
20、 comes from direct experience with the world. But Radford and other scientists are exploring a third kind of knowledge：information from fellows.Radford and researchers at the Australian National University carried out the study in the countrys National Botanic Gardens in Canberra. They attached spec
21、ially-designed，sound-producing equipment called “tweeter speakers” to their bodies. They wanted to see if fairy wrens would react to sounds of other birds even if they could not see them.The scientists first played the birds two recorded sounds that they likely had never heard before. One was a warn
22、ing cry of a thornbill (刺喙蜂鸟), a bird not native to Australia. The other was a computer-generated bird sound called “buzz”When the 16 fairy wrens in the study first heard the sounds，they had no special reaction. The scientists then tried to train half of the birds to recognize the thornbills cry as
23、a warning sound. They tried to train the other half to recognize the computer-generated “buzz” as a warning call.After three days, the scientists tested what the birds had learnedand their “students” passed the test. The fairy wrens trained with the thornbills cry, fled when they heard it. The group
24、 trained with the “buzz”， fled when they heard that sound.Neither group reacted to the sound taught to the other.文章大意：本文是一篇说明文。作者通过介绍Radford和澳大利亚国立大学的研究人员在堪培拉的国家植物园开展的研究实验，说明了鸟类可以通过人为培训，从而“识别声音”。1What does the underlined word “predators” in the first paragraph mean？ A AEnemies.BNeighbors.CBirds. DSn
25、akes.解析：词义猜测题。根据第一段第二句“Some birds，for example，flee when neighbors make a loud noise to announce a snakes presence.”可知，有一些鸟在它们的邻居发出大叫来宣告有蛇出没时会逃跑。由此可推知，画线词所在句表示当天敌就在附近时，野生动物会互相倾听警告。故画线词的词义与A项相近。2Which is the right order of the experiment？ B aThe fairy wrens were divided into two parts.bThe fairy wrens
26、 made no reaction to the strange sounds.cRadford and researchers wore sound-producing equipment.dThe fairy wrens were trained separately.eThe fairy wrens passed the test successfully.Aabcde BcbadeCcebad Dacedb解析：细节理解题。由第五至八段的内容可知，实验的顺序是：Radford和研究人员穿戴声音产生装备、科学家播放两组录音但细尾鹩莺未对录音作出反应、细尾鹩莺被分成两组分别训练、最后细尾鹩
27、莺成功通过测试。故选B。3It can be learned from the study that the fairy wrens D .Awere not good “foreign language” learnersBmade no reaction to the sounds all the timeCtook both of the sounds as warningsDfled when hearing the sound taught to them解析：推理判断题。根据文章最后一段可知，细尾鹩莺被训练成功，通过了测试，当它们听到训练时代表警告的声音时，它们会飞走。故选D。4T
28、he passage is probably taken from B .Aa biology textbook Ba science magazineCa science fiction Da wildlife brochure解析：文章出处题。根据文章内容可知，本文是一篇说明文，作者通过介绍Radford和澳大利亚国立大学的研究人员在堪培拉的国家植物园开展的研究实验，说明了鸟类可以通过人为培训，从而“识别声音”。由此可推知，本文很可能摘自科学杂志。故选B。B(2020湖南省高三六校联考)If I scratch your back and you scratch mine, then we
29、re both better off as a resultso goes the principle of reciprocity. As humans, we are familiar with the concept, whether it is by buying rounds of drinks or expelling diplomats. But do animals also help those who help them? The answer may be yes. A paper by Dolivo and Taborsky shows that Norway rats
30、 will only give as good as they get.In their laboratory, Dolivo and Taborsky first trained rats to pull a stick that provided a food item within the reach of a rat in a neighboring cage separated from them by wire mesh(铁丝网)They then introduced a further treatment in which an experimental rat was pla
31、ced in a cage with other caged rats on either side. On one side the rat pulled a stick that provided pieces of carrot to the rat in the central cage, while the other pulled a stick that produced banana pieces.In the following trials the focal rat (the one in the central cage) had the opportunity to
32、repay the other rats using the same stick tool to deliver food items.Now, the rats had typically turned their noses up at the carrot and showed a strong preference for the more desirable banana. On the basis that the banana-providing rat should be therefore remembered as the superior partner, the au
33、thors predicted that in the test phase (阶段) the focal rat would more readily provide help for banana-offering rats than for carrot-offering rats. This proved to be the case: the rats that had provided better help in the past received greater rewardsit seemed that they were behaving reciprocally.Doli
34、vo and Taborskys experiments show that rats can recall the quality of help provided and by which rat, and adjust their behavior so as to invest more time and energy in helping those that helped them. It is apparent that we shouldnt undervalue the ability of animals to engage in reciprocity.文章大意：本文是一
35、篇说明文。文章详细介绍了Dolivo和Taborsky用挪威老鼠做实验得出结论的过程。实验的结果告诉人们，我们不应该低估动物的互惠能力。5What does the underlined word “reciprocity” probably refer to？ B AThe act of being kind to other people.BA cooperative exchange of favors.CA positive attitude to everything.DThe quality of being generous.解析：词义猜测题。根据第一段第一句中的“If I sc
36、ratch your back and you scratch mine，then were both better off as a result”可知，如果两个人互相抓背，则两人都能得到好处，由此可推知，reciprocity意为“互惠”。故B项正确。6What would happen if a rat pulled the stick？ C AIt would find some food in its own cage.BOther rats would be able to enter its cage.CAnother rat in another cage would get
37、food.DIt would be able to enter a neighboring cage.解析：推理判断题。根据第二段的内容和第三段尾句“On one side the rat pulled a stick that provided pieces of carrot to the rat in the central cage, while the other pulled a stick that produced banana pieces.”可推知，如果一只老鼠拉棍子，则另一个笼子里的老鼠会吃到食物。故C项正确。7Which got more benefit from th
38、e focal rat？ D AThe rats that preferred carrot pieces.BThe rats that preferred banana pieces.CThe rats that had provided carrot pieces.DThe rats that had provided banana pieces.解析：细节理解题。根据倒数第二段的内容尤其是“the rats that had provided better help in the past received greater rewards”可知，提供香蕉片的老鼠会得到更多的回报。故D项正
39、确。8Which of the following might Dolivo and Taborsky agree with？ A ASome animals may return others help.BNorway rats have very poor memories.CIt is hard to explain the ability of animals.DRats behavior is very uncommon.解析：推理判断题。根据尾段第一句“Dolivo and Taborskys experiments show that rats can recall the qu
40、ality of help provided and by which rat，and adjust their behavior so as to invest more time and energy in helping those that helped them.”可知，Dolivo和Taborsky的实验表明，老鼠能够回忆起谁提供的帮助和帮助的质量，并调整它们的行为，从而投入更多的时间和精力去帮助那些帮助过它们的同类，由此可推知，动物会回报帮助过它们的对象。故A项正确。.短文改错In China, people and giant pandas had been living to

46、类的发展，熊猫的栖息地越来越小，它们的生活和繁衍受到严重影响，但让人欣慰的是人们正在帮大熊猫建保护区。解析：1考查动词的时态和语态。此处指人们和大熊猫到“现在”为止已经生活了几千年了。所以谓语动词应选用现在完成进行时“have been doing”。2考查副词。该句意思为：中国人口已经大幅度的增长，此处greatly 修饰谓语动词“have been growing”，故用副词。3考查动词的时态。根据上下文可知此处应为一般现在时，又因该句主语为“it”，故用第三人称单数。4考查非谓语动词。此处为不定式作宾语补足语，force sb./sth.to do sth.“迫使某人或某物做某事”，是固
47、定用法。5考查非谓语动词。damaged“被破坏了的”，damaging“有破坏性的”，此处为分词作定语，修饰result，表示有破坏性的结果。6考查名词的数。panda前面由many修饰，故用复数。7考查连词。because of后面接名词、动名词或what引导的从句，because后面接除what以外的词引导的从句。8考查定语从句。此处先行词areas在后面的定语从句中作地点状语，故选用关系副词where或in which或在不及物动词live后加in。9考查上下文语境。分析上下文可知此处意为“结果就是大熊猫不能够与另外的配偶联系、不能够繁殖”。10考查副词。上文在说不好的结果，但下文说“让人欣慰的是”，表转折。
