2、els of food webs,noting who eats whom and how much each one eats.With such models,scientists have found out some key principles operating in food webs.Most food webs,for instance,consist of many weak links rather than a few strong ones.When a predator(掠食动物) always eats huge numbers of a single prey(

3、猎物),the two species are strongly linked;when a predator lives on various species,they are weakly linked.Food webs may be dominated by many weak links because that arrangement is more stable over the long term.If a predator can eat several species,it can survive the extinction(灭绝) of one of them.And

4、if a predator can move on to another species that is easier to find when a prey species becomes rare,the switch allows the original prey to recover.The weak links may thus keep species from driving one another to extinction.Mathematical models have also revealed that food webs may be unstable,where

5、small changes of top predators can lead to big effects throughout entire ecosystems.In the 1960s,scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other speciesincluding species they did not directly attack.And unplanned hu

6、man activities have proved the idea of top-down control by top predators to be true.In the ocean,we fished for top predators such as cod on an industrial scale,while on land,we killed off large predators such as wolves.These actions have greatly affected the ecological balance.Scientists have built

7、an early-warning system based on mathematical models.Ideally,the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline.Prevention is key,scientists say,because once ecosystems pass the

8、ir tipping point(临界点),it is remarkably difficult for them to return.【语篇解读】本文是一篇说明文。主要讲述了科学家们利用建立的食物网数学模型,发现了食物网运行的基本原则以及人类活动对于生态系统的影响。1.What have scientists discovered with the help of mathematical models of food webs?A.The living habits of species in food webs.B.The rules governing food webs of the

9、 ecosystems.C.The approaches to studying the species in the ecosystems.D.The differences between weak and strong links in food webs.答案:B解析:细节理解题。根据文章第二段第一句中的“.scientistshavefoundout.infoodwebs.”得知科学家们发现了食物网运行的关键法则,即B项。2.A strong link is found between two species when a predator .A.has a wide food ch

10、oiceB.can easily find new preyC.sticks to one prey speciesD.can quickly move to another place答案:C解析:细节理解题。根据第二段第三句中的“Whenapredator.arestronglylinked.”得出结论,只吃一种猎物是“stronglink”。3.What will happen if the populations of top predators in a food web greatly decline?A.The prey species they directly attack

11、will die out.B.The species they indirectly attack will turn into top predators.C.The living environment of other species will remain unchanged.D.The populations of other species will experience unexpected changes.答案:D解析:推理判断题。根据第三段第一句“Mathematicalmodels.entireecosystems.”可知“食物链顶端掠食动物的变化可能会给整个生态系统带来大

14、eed for taking preventive action.答案:D解析:推理判断题。根据文章最后一段第二句可知这个系统会告诉我们何时对把生态系统推向瘫痪的人类活动作出调整以及最后一句话中的“Preventioniskey”可知D项正确。BThere is a very special wolf that lives in Africa.They are actually called,the African wild dogs,or painted dogs.These animals live in open woodlands,or in the plains of Africa.

15、Today,however,most of the animals can be found in eastern or southern Africa.These animals are beautiful.They have rounded ears instead of pointed like most dogs,and they have four toes on each of their four feet,also a unique characteristic because other dogs have five.Their fur is always different

16、 from each other.The fur is usually a combination of black,brown,red and white,and sometimes even yellow.No wonder theyre called the painted dogs.The African wild dog is a very social animal.They live in groups and have numbers from five to about twenty.The members of a group are always very close t

17、o one another.They communicate in their own language or body language.When someone is very old or sick,the others will help,and they are willing to share the food with the elders and with those who are weak,which is what we should learn from.The family does everything together,from raising young,to

18、sleeping together,to hunting.When they hunt,they will work together using team work to kill animals that are larger than them.They sometimes hunt farm animals.This is unfortunate,because both poachers,and people who own farms shoot the painted dogs who are just trying to survive.Before,there used to

19、 be many large groups throughout the land,but now the African wild dog is very rare.They are also losing their population because of their own loss of habitat thanks to humans farming and forest cutting.【语篇解读】本文是一篇说明文。文章介绍了非洲野狗的相关信息及其生存现状。6.From the passage we learn that the African wild dog .A.live

20、s in the north of AfricaB.has sixteen toes altogetherC.has pointed ears like most dogsD.lives in forests in groups答案:B解析:推理判断题。根据第二段第一句内容可知,非洲野狗出没在开阔的林地或平原,故D项错误;根据第二段第二句可以推断出A项错误;根据第二段的“Theyhaveroundedearsinsteadofpointedlikemostdogs.”可知,C项错误;由第二段第四句可知,B项正确。7.Why do African wild dogs get the name “

21、painted dogs”?A.They all have colorful fur.B.The dogs in the same group are of different colors.C.Artists love to paint them in different colors.D.None of them has the same color.答案:A解析:细节理解题。由第二段最后两句可知,非洲野狗之所以被称为“彩色狗”是因为它们的皮毛是彩色的,故A项正确。8.According to the author,what should we learn from African wil

22、d dogs?A.They always do everything together.B.They help the sick,the elderly and the weak.C.They are always very close to one another.D.They communicate in their own language.答案:B解析:细节理解题。根据第三段最后一句可知,当有非洲野狗年老或生病的时候,其他的非洲野狗就会帮助它们,并且愿意与其分享食物,这一点是我们人类应该学习的。故选B项。9.Which of the following is NOT the reaso

24、obably be found?A.TheTravelers.B.FashionWeekly.C.AnimalWorld.D.StarMagazine.答案:C解析:文章出处题。本文介绍了非洲野狗这种动物,最有可能是在动物世界里出现,故选C项。CA scientist working at her lab bench and a six-month-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to

25、 uncover the very nature of the physical world,and the baby is,well,just playing.right?Perhaps,but some developmental psychologists(心理学家) have argued that this “play” is more like a scientific investigation than one might think.Take a closer look at the baby playing at the table.Each time the bowl o

26、f rice is pushed over the table edge,it falls to the groundand,in the process,it brings out important evidence about how physical objects interact(相互作用):bowls of rice do not float in mid-air,but require support to remain stable.It is likely that babies are not born knowing this basic fact of the uni

27、verse;nor are they ever clearly taught it.Instead,babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact.Though their ranges and tools differ,the babys investigation and the scientists experiment

28、appear to share the same aim(to learn about the natural world),overall approach(gathering direct evidence from the world),and logic(are my observations what I expected?).Some psychologists suggest that young children learn about more than just the physical world in this waythat they investigate huma

29、n psychology and the rules of language using similar means.For example,it may only be through repeated experiments,evidence gathering,and finally overturning a theory,that a baby will come to accept the idea that other people can have different views and desires from what he or she has,for example,u

30、nlike the child,Mommy actually doesnt like Dove chocolate.Viewing childhood development as a scientific investigation throws light on how children learn,but it also offers an inspiring look at science and scientists.Why do young children and scientists seem to be so much alike?Psychologists have sug

31、gested that science as an effortthe desire to explore,explain,and understand our worldis simply something that comes from our babyhood.Perhaps evolution(进化) provided human babies with curiosity and a natural drive to explain their worlds,and adult scientists simply make use of the same drive that se

32、rved them as children.The same cognitive(认知的) systems that make young children feel good about figuring something out may have been adopted by adult scientists.As some psychologists put it,“It is not that children are little scientists but that scientists are big children.”【语篇解读】本文是一篇议论文。科学家在实验室做实验和

33、婴幼儿摆弄自己的饭碗有共同之处吗?也许你想象不到,但是发展心理学家指出这两种行为同样都是科学调研。文章通过实例论述了孩子通过玩耍认识到物体的相互作用,认识到人类心理以及语言使用规则。最后,心理学家揭示了科学调研内在的根本原因和驱动力就是人类从婴儿阶段就具有的“好奇心”。11.According to some developmental psychologists,.A.a babys play is nothing more than a gameB.scientific research into babies games is possibleC.the nature of babies

34、 play has been thoroughly investigatedD.a babys play is somehow similar to a scientists experiment答案:D解析:细节理解题。由文章第一段最后一句中“.somedevelopmentalpsychologistshavearguedthatthisplayismorelikeascientificinvestigation.”可知科学实验和孩子的玩耍这两种行为均包含一种共性。D项中issomehowsimilarto和句中ismorelike为同义替换。12.We learn from Paragr

35、aph 2 that .A.scientists and babies seem to observe the world differentlyB.scientists and babies often interact with each otherC.babies are born with the knowledge of object supportD.babies seem to collect evidence just as scientists do答案:D解析:细节理解题。在第二段中,作者通过实例论证了婴儿的玩耍和科学家们的实验两者间存在的共性,即目的、方法和逻辑相同。注意

36、该段落最后一句话括号中的信息:gatheringdirectevidencefromtheworld,D项中的collect和gathering属于同义替换。故选D项。13.Children may learn the rules of language by .A.exploring the physical worldB.investigating human psychologyC.repeating their own experimentsD.observing their parents behaviors答案:C解析:推理判断题。推理判断的起点是第三段第一句中“usingsimi

37、larmeans”这一说明。既然调查人类心理和语言规则的方法同上,则应该从上文的第二段中找到对应的方法,即第二段倒数第二句中“throughrepeatedexperiments”,因此选择C项。14.What is the main idea of the last paragraph?A.The world may be more clearly explained through childrens play.B.Studying babies play may lead to a better understanding of science.C.Children may have g

38、reater ability to figure out things than scientists.D.Ones drive for scientific research may become stronger as he grows.答案:B解析:主旨大意题。段落的首句为该段的主旨句。该句句意:把儿童的发展看作是一个科学研究的过程,这阐明了孩子学习的方法;同时也对怎样看待科学和科学家具有启示性意义。因此研究婴儿的玩耍的科学性可以更好地理解科学本身的发展,故B项正确。15.What is the authors tone when he discusses the connection

39、between scientists research and babies play?A.Convincing.B.Confused.C.Confident.D.Cautious.答案:D解析:推理判断题。该题要求判断作者的语气(tone),须从作者的用词来做出判断,特别是副词、形容词、情态动词等的使用。第一段中“Perhaps”,第二段中“Itislikelythat.,may,appear”,第三段中的“may”,以及第四段中“Perhaps,may”等这些词都说明了作者在下结论或做出判断时所持有的谨慎(cautious)态度。D(2017天津红桥区二模)Long ago,poems w
