题组层级快练(十九)
Ⅰ. 阅读理解
Wild animals are known to listen to each other for warnings that predators are near. Some birds, for example, flee when neighbors make a loud noise to announce a snake's presence.The fairy wren(细尾鹩莺) is a small Australian songbird. 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. He 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 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 country's National Botanic Gardens in Canberra. They attached specially-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 warning 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 thornbill's cry as 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 learned－and their “students” passed the test. The fairy wrens trained with the thornbill's cry, fled when they heard it. The group trained with the “buzz”， fled when they heard that sound. Neither group reacted to the sound taught to the other.
1. What does the underlined word “predators” in the first paragraph mean?
A. Enemies. C. Birds.
B. Neighbors. D. Snakes.
2. Which is the right order of the experiment? a. The fairy wrens were divided into two parts.
b. The fairy wrens made no reaction to the strange sounds. c. Radford and researchers wore sound-producing equipment. d. The fairy wrens were trained separately. e. The fairy wrens passed the test successfully. A. abcde. C. cebad.
B. cbade. D. acedb.
3. It can be learned from the study that the fairy wrens ________. A. were not good “foreign language” learners B. made no reaction to the sounds all the time C. took both of the sounds as warnings D. fled when hearing the sound taught to them 4. The passage is probably taken from ________. A. a biology textbook C. a science fiction 答案与解析
【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”。 1．答案 A
解析 考查词义猜测。根据第一段第二句“Some birds, for example, flee when neighbors make a loud noise to announce a snake's 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
B. a science magazine D. a wildlife brochure
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。 2．答案 B
解析 考查细节理解。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做出反应、细尾鹩莺被分成两组分别训练、最后细尾鹩莺成功通过测试。故选B项。 3．答案 D
解析 考查推理判断。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项。 4．答案 B
解析 考查文章出处。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项。 Ⅱ. 完形填空
When Mrs. Green told her pupils to draw a picture of something for which they were thankful, she thought how little these children in a(an) __1__ neighborhood, had to be __2__ for. Most of the __3__ would draw pictures of turkeys (火鸡) or of Thanksgiving tables full of everything __4__ to eat. That was what they believed was __5__ them.

Mrs. Green had almost forgotten David in her __16__ at finding the class so responsive(共鸣的). Having the others working on another project, she bent over his __17__ and asked whose hand it was. David whispered, “It's yours, Teacher.”
Then Mrs. Green __18__ she had taken David by the hand from time to time; she often did that with the children. But that it should have __19__ so much to David ... Perhaps, she thought this was her Thanksgiving, and everybody's Thanksgiving—not the things given to us, but the small __20__ that we give something to others. 1. A. bettering C. interesting 2.
