I will not let you be disho

16、come home.”可知，作者由于特别想 家，所以想要放弃体操。故 B 项符合题意。 17A细节理解题。根据文章第三段“Youre breaking my heart，Brie.”可知，妈妈听 说我要半途而废感到心碎。故选 A 项。 18 C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
17、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。 B How 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
18、few wolves? To find an answer，scientists have built mathematical models 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 example，is made up of many weak links rather than a few stro
19、ng 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 lives 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 ca
20、n 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 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. Math
21、ematical models have also shown that food webs may be unstable，where small changes of top predators can lead to big effects throughout 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 oth
22、er speciesincluding species they did not directly attack. And unplanned human activities have proved the idea of topdown 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 a
23、ctions have greatly affected the ecological balance. Scientists have built an earlywarning 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 bo
24、rderline.Prevention is key，scientists says, because once ecosystems pass their tipping point(临界点)，it is remarkably difficult for them to return. ()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 fo
25、od webs of the ecosystems. CThe ways to studying the species in the ecosystems. DThe differences between weak and strong links in food webs. ()22.Astrong link is found between two species when a predator _. Ahas a wide food choice Bcan easily find new prey Csticks to one prey species Dcan quickly mo

BThe species they indirectly attack will turn into top predators. CThe living environment of other species will remain unchanged. DThe pop
27、ulations of other species will experience unexpected changes. ()24.What conclusion can be drawn from the examples in Paragraph 4? AUncontrolled human activities greatly upset ecosystems. BRapid economic development threatens animal habitats. CSpecies of commercial value dominate other species. DIndu
28、strial activities help keep food webs stable. ()25.How does an early warning system help us maintain the ecological balance? ABy getting illegal practices under control. BBy stopping us from killing large predators. CBy bringing the brokendown ecosystems back to normal. DBy signaling the urgent need
29、 for taking preventiveaction. 【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 out 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 hu

34、es 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 the main differences between life in ancient times and that of today. Stone Age people hunted wild animals fo
35、r 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 grains._29_ We eat six times more salt than our ancestors.We eat more sugar.We eat twice as much fat but only
36、 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 and sweet food. AStone Age people lived a simple life. BBut today，we enjoy eating a lot of these. CIn that
37、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 ancestors. 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
