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
6、, 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 instance, consist of many weak links rather than a few strong ones. When a predator(掠
7、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 by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, i
8、t can survive the extinction(灭绝) 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. Mathematical models
9、have also revealed that food webs may be unstable, where 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 species-inc
10、luding species they did not directly attack. And unplanned human 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 h
11、ave greatly affected the ecological balance. Scientists have built 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 borderl
12、ine. Prevention is key, scientists say, because once ecosystems pass their tipping point(临界点), it is remarkably difficult for them to return. 【文章大意】本文主要讲述了科学家们已经建立了一个基于食物网的数学模型预警系统, 该系统揭示食物链中的生态平衡和破坏的原理和提醒人们应该保护生态系统。1. What have scientists discovered with the help of mathematical models of food webs
13、?A. The living habits of species in food webs. B. The rules governing food webs of the ecosystems. C. The approaches to studying the species in the ecosystems. D. The differences between weak and strong links in food webs. 【解析】选B。细节理解题。根据文章第二段With such models, scientists have found out some key prin
14、ciples operating in food webs. 可知, 通过这些模型, 科学家们发现了一些在食物网中起作用的关键原理。由此可见, 科学家借助于食物网的数学模型发现了控制生态系统食物网的规则。2. A strong link is found between two species when a predator _. A. has a wide food choiceB. can easily find new preyC. sticks to one prey speciesD. can quickly move to another place【解析】选C。细节理解题。根据文
15、章第二段If a predator can eat. . . prey to recover. 可知如果一个捕食者可以吃几个物种, 它就可以在其中一个物种灭绝后幸存下来。如果一个捕食者可以转移到另一个物种, 当一个捕食物种变得稀少时, 更容易找到这个物种, 那么这个转换就允许原来的捕食者恢复。由此可见, 当食肉动物粘在一个捕食物种上时, 发现两个物种之间有一个很强的联系。3. What will happen if the populations of top predators in a food web greatly decline?A. The prey species they di
16、rectly attack 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. 【解析】选D。推理判断题。根据文章第三段第一句可知数学模型还表明, 食物网可能是不稳定的, 顶部食肉动物的微小变化可能导致整个生态系
17、统的巨大影响。由此可见, 如果食物网中顶级食肉动物的数量大幅度下降, 其他物种的种群将经历意想不到的变化。4. What conclusion can be drawn from the examples in Paragraph 4?A. Uncontrolled human activities greatly upset ecosystems. B. Rapid economic development threatens animal habitats. C. Species of commercial value dominate other species. D. Industri
18、al activities help keep food webs stable. 【解析】选A。推理判断题。根据文章第四段可知无计划的人类活动证明了顶级掠食者自上而下控制的想法是正确的。在海洋中, 我们在工业规模上捕捞顶级掠食者, 如鳕鱼, 而在陆地上, 我们杀死大型掠食者, 如狼。这些行动大大影响了生态平衡。由此可见, 不受控制的人类活动极大地破坏了生态系统。. 语法填空(2021大连高一检测)A kind of insect gets its name for the body shape, which resembles a long stick.
