阅读机经 (都是用英文回想起来的,然后自己翻译了下中文,所以英文比较接近原文题目原句)
1. 地核和地幔(短文):笛卡尔设想地球内部结构是层层叠叠的:最内部是液体的核,外面是固体的核。(有题:为啥作者提到笛卡尔的理论?答案:说明当代理论保留了原先理论的一些特点)当今科学家依然遵循层叠结构。只不过地核是:固体的内核,液态的外核(生词:molten),承受高温高压,铁含量高。地核的外面和地表之间的是地幔:可分成上地幔和下地幔,相差xx公里,镁元素含量高。(有题:和地核相比,地幔的特点是什么?答案:几乎没有液体(百度了一下:地幔物质具有一些可塑性,但没有熔成液体,可能局部处于熔融状态)愚蠢的干扰选项:高温,高压,含铁量高,有两层)
1. Earth core and mantle: Descartes assumes the earth is layered. With liquid inner core and solid outer core. Nowadays scientists still follow this layered model (Question: why mention Descartes’ theory of earth? Answer: to demonstrate current theory retains some features of it. ) The core is made of two parts: there is a solid inner core and molten outer core, enduring high pressures and temperature, and rich in iron. Below the surface is the mantle; one solid layer is XX kilometer from another, rich in magnesium. (Question: what is the distinctive of the earth mantle as compared to the core? A: high pressure, B high temperature C two layers D. mantle contain almost no liquid E. richer in iron.)
2. 石楠甲虫和荷兰草地(短文):欧洲低地的生态环境受氮气影响很大。荷兰的石楠地很多变成了草地,是氮气和石楠甲虫共同引起的。氮气帮助草和石楠同时生长,石楠先长的快,所以草就被压在石楠的枝干下面。石楠甲虫的数目每年都变化。(有题:为啥提到石楠甲虫每年数量不一?候选答案有:强调一个管理草地中不可控的因素,体现生态环境脆弱,表现今年甲虫多明年甲虫肯定少)甲虫就渐渐吃石楠,树叶慢慢掉光,由此草就疯长。(有题:可以推断关于甲虫的事实是?答案:甲虫帮助了草接触到阳光)
2. Heather Beetle and Dutch grassland: The ecological system of low land in Europe is dynamic. Nitrogen exerts big influence on Dutch heather land. The change of heather land to grassland is the interplay between not only the nitrogen level, but also the presence of heather beetles. Nitrogen will encourage both grass and heather to grow. But the heather grow quicker first, therefore the grass is under their bushes. The number of beetles, however, varies from year from year (Question: Why mention the number of beetles here? A. to stress one factor that is out of control of grassland management B. to demonstrate the system is fragile, C. to show one year of abundance is definitely going to be followed by scarcity. D….E….) As the beetles eat more heather, many leafs drop off, the grass have more space. (Question: what can be inferred, A. the beetles help the grass to reach to more sun light)
3. 野猫的驯养(短文,文章简单,题目很难巨扣字眼)野猫很难被驯养。首先,它们的消化系统只适合蛋白质食物。第二:它们独来独往保持自己的领地。第三,它们不表演人类指示的任务。野猫也许是可以作为捕鼠帮手;但是,这个用处值得讨论质疑。因为捕鼠的犬类(比如梗)更加受到青睐。介于这些原因,没什么理由可以猜想早期农业社会特意驯养猫作为宠物。猫后来和人一起生活的唯一理由/途径只不过是,人类容忍了猫的存在,然后猫就慢慢丧失了野性。(有三个问题,只记得一个问题:以下除了哪个都是早期农业社会的特点?候选答案:人类因为猫的用处容忍了猫的存在(我选了这个)。那时人类生产的食物不适合猫。人来偏好狗来捕鼠(同义词rodent)。人类和动物共享生存空间。人类驯养其他动物)
3. Wild Cat and domestication: Cats are hard to domesticate. First of all, they have a digest system that cannot eat anything but protein. Second, they live secluded life and have protective territory. Third, they do not perform any directed tasks. It might be the case that cats could serve as catchers of mouse; however, this utility is debatable; arguably, terriers and other dogs are preferred in this task. Hence, there is hardly any reason to think any early agriculture society would have cats as pet. The only reason why cats and human live together is probably because human merely tolerate the existence of cats, which gradually lost their wildness in the long run. (Question: all of following about early agricultural society is true EXCEPT: A: they tolerate cats for their utility B. they produce food not suitable for cats C. They prefer terriers to catch the rodents D. they share space with animals. E they have domesticated certain other animals)
4. 纽约州化石发现(短文):最近纽约上州发现的化石对科研有帮助:首先,一种菌类的化石在某年完全消失了,这种菌类只寄生在大型食草动物上。然后,烧焦的植物化石(类似煤炭)同时大幅出现。因此科学家猜测:大型食草动物的数量在和人类接触之后迅速下降,因为人类发现它们很容易被捕猎。当动物渐渐消失,植物就越发茂盛。人类生火的时候,火苗就很容易在易燃的植物上扩散。(问题:关于食草动物可以推出什么事实?候选答案:它们的存在控制了火苗可能传播的广度(我选了这个)。它们导致菌类的消失。它们的数量在人类到达的时候达到顶峰。它们在遇到人类之前几乎没有天敌。)
4. Fossils in New York State: The fossil of one fungus, which only grew on big herbivore animals, disappeared X years ago. Then, the fossils of burned vegetation (similar to coral) appear in large amount. Scientist A infers a possible hypothesis: the number of large herbivore animals crashed when human settled in the area, who found the animals, quite inexperience with human, as easy preys. As those animals disappeared, no one ate the grass and lots of grass grew. When human make fire, fire spread quickly on those plants. (Q: what can be inferred from big herbivore animals? A: their existence helps to keep a balance of how wide fire can spread, B. herbivore are responsible for the disappearance of fungus, C. the number of herbivore animals peaked just before human arrived. D. Herbivores hardly have any predators before the arrival of human. E….)
