8、es away.On January 2,2012，while Mom was visiting me in Iowa，I told her，“I dont like gymnastics anymore.I want to try dancing，or become a singer.I can get a job in Virginia.I just want to come home.”Moms eyes narrowed and her expression turned to stone.“Youre breaking my heart，Brie.” She said.“Youve

9、been doing gymnastics for ten years，and now you want to quit? Have you lost your mind？”I hadnt lost my mind，but I had lost my fire.Its an entirely different thing to push toward that dream when you feel alone.“Im not trying to break your heart，Mom，” I said.“I just dont want to do it anymore.” “I kno

10、w you miss home.But youve signed a contract that says you will represent your country to the best of your ability.Youve got a responsibility to your teammates.And now you just want to walk away? I will not let you be dishonorable.If you dont like gymnastics，then at the very least，you will finish the

11、 season.”The next afternoon as I dragged myself into Chows gym，I thought of the efforts Mom had made in order to pay for my training.I thought of my two sisters: Arielle，who gave up ballroom dancing，and Joyelle，who stopped ice skating so that our single mom could afford to keep me in gymnastics.For

16、心碎。故选A项。18C推理判断题。根据文章最后一段“Exactly 210 days before I ever attempted my first vault (跳跃) in the London Summer Olympics”可知，作者在210天后参加了伦敦奥运会，因此可推断出，作者最后改变了主意，并没有放弃体操。故选C项。19B主旨大意题。作者最初想放弃体操，但最后选择了坚持。B项标题概括了文章的主旨并与文章最后一段“my leap of faith came this close to ending in a crash of disaster”呼应。故选B项。20D推理判断题。作

17、者因为想家想放弃体操训练，但母亲的一席话让她最终选择了坚持，故答案选D项。BHow does an ecosystem(生态系统)work？What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer，scientists have built mathematical models of food webs，noting who eats whom and how much each one e

18、ats.With such models，scientists have found out some key principles operating in food webs.Most food webs，for example，is made up 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(猎物)，the two species are strongly linked; when a predator liv

19、es on various species，they are weakly linked.Food webs may be dominated (支配) by many weak links because that arrangement is stabler over the long term.If a predator can eat several species，it can survive the extinction of one of them.And if a predator can move on to another species that is easier to

20、 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 shown that food webs may be unstable，where small changes of top predators can lead to big effects throughout

21、 entire ecosystems.In the 1960s，scientists pointed out 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 human activities have proved the idea of topdown control by top

22、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 an earlywarning system based on mathematical models.Ideally，the

23、 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 says, because once ecosystems pass their tipping point(临界点)，it is remarkably difficult for them to r

24、eturn.()21.What have scientists discovered with the help of mathematical models of food webs?AThe living habits of species in food webs.BThe rules governing food webs of the ecosystems.CThe ways to studying the species in the ecosystems.DThe differences between weak and strong links in food webs.()2

25、2.A strong link is found between two species when a predator _.Ahas a wide food choiceBcan easily find new preyCsticks to one prey speciesDcan quickly move to another place()23.What will happen if the populations of top predators in a food web greatly decline?AThe prey species they directly attack w

26、ill die out.BThe species they indirectly attack will turn into top predators.CThe living environment of other species will remain unchanged.DThe populations of other species will experience unexpected changes.()24.What conclusion can be drawn from the examples in Paragraph 4?AUncontrolled human acti

27、vities greatly upset ecosystems.BRapid economic development threatens animal habitats.CSpecies of commercial value dominate other species.DIndustrial activities help keep food webs stable.()25.How does an early warning system help us maintain the ecological balance?ABy getting illegal practices unde

28、r control.BBy stopping us from killing large predators.CBy bringing the brokendown ecosystems back to normal.DBy signaling the urgent need for taking preventive action.【语篇解读】本文是说明文，介绍了借助食物链的数学模式，科学家们发现了一些食物链运行的关键规则。科学家们说，一旦生态系统越出了它的临界点，就很难将其复原。21B细节理解题。根据第一段“With such models, scientists have found o

29、ut some key principles operating in food webs.”可知，借助食物链的数学模式，科学家们发现了食物链的运行规则。故选B。22C细节理解题。根据第二段“When a predator (掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked”可知，当捕食者总是吃大量的单一猎物，这两个物种是紧密相连的。故选C。23D推理判断题。根据第三段“predators at the top of a food web had, a surpris

30、ing amount of control over the size of populations of other species they did not directly attack”可知，处于食物链顶端的食肉动物对它们没有直接攻击的其他物种的种群数量有着惊人的控制，由此可推断出，如果食物链顶端的食肉动物的数量大大下降，其他物种的种群将经历意想不到的变化。故选D。24A推理判断题。根据第五段“Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem to

31、ward a breakdown or would even allow us to pull an ecosystem back from the borderline.”可知，人类过度的活动会将生态系统推向崩溃，由此可推断出，不受控制的人类活动极大地破坏了生态系统。故选A。25D细节理解题。根据最后一段可知，早期预警系统发出紧急需要采取预防行动的信号帮助我们维持生态平衡。故选D。第二节(共5小题；每小题2分，满分10分)Recently some American scientists have given a useful piece of advice to people in ind

32、ustrialized nations.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago._26_The scientists say that the human life has changed greatly.Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknes

33、ses._27_ So they are called “diseases of civilization”Many cancers and diseases of the blood system are examples of such diseases.Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco，probably none._28_ However，a change in food is one of

34、the main differences between life in ancient times and that of today.Stone Age people hunted wild animals for their meat，which had much less fat than domestic ones.They ate a lot of fresh wild vegetables and fruits.They did not have milk or any other dairy products，and they made very little use of g

35、rains._29_ We eat six times more salt than our ancestors.We eat more sugar.We eat twice as much fat but only one third as much protein and much less vitamin C._30_ But scientists say that we would be much healthier if we eat much the same way the ancient people did，cutting the amount of fatty，salty

36、and sweet food.AStone Age people lived a simple life.BBut today，we enjoy eating a lot of these.CIn that case，they would live much healthier.DAncient people also got lots of physical exercise.EThese new sicknesses were not known in ancient times.FPeople today probably dont want to live like our ances

37、tors.GModern people used to suffer from “diseases of civilization”【语篇解读】本文是议论文。作者提出了一种观点，认为现代人的生活方式、食物结构发生了很大变化，随之而来的是各种 “文明病”的兴起。要阻止这种现象就要回到石器时代向古人学习。26C前面提到“建议人们回到10, 000多年前，像当时的人们那样吃东西”，为什么呢？后续语境给出答案：为了健康。故选C。27E上文提到，我们的身体不能应对生活方式的改变，因此带来了一些新的疾病，现在人们称之为“文明病”，而以前呢？在古代却没有听说过这些疾病。故选E。 28D此处关联语境为新石器和

38、旧石器时代人们的生活方式，5个选项中只有D与之匹配：古人也有很多体育锻炼。因此D项符合语境。 29B前面为古人的饮食特点，下文为现代人的饮食结构，而此处承上启下，作为过渡。故选B项(但是今天，我们喜欢吃很多这样的东西)。30F所在部分为全文结论。But表转折，后面为科学家建议的饮食结构，故空格处应表达与此相反的内容，故选F项(今天的人们可能不想像我们的祖先那样生活)。第三部分完形填空(共15小题；每小题1分，满分15分)Honesty is always the best policy，especially when it comes to mental health problems.In

39、a TV _31_，one girl gets very real about dealing with anxiety and panic.“I was the best student in my high school.I put so much _32_ on myself，” she said，“I never _33_ a class.But I got sick during 10th grade and I started to_34_.That was when the panic attacks began.” She goes on to describe what a
