The Pace of Evolutionary Change A heated debate has enlivened recent studiesof evolution.Darwin's original thesis,and theviewpoint supported by evolutionary gradualists,isthat species change continuously but slowly and insmall increments.Such changes are all but invisible over the short time scale of modernobservations,and,it is argued,they are usually obscured by innumerable gaps in theimperfect fossil record.Gradualism,with its stress on the slow pace of change,is a comfortingposition,repeated over and over again in generations of textbooks.By the early twentiethcentury,the question about the rate of evolution had been answered in favor of gradualism tomost biologists'satisfaction. 最近的一个关于进化的研究引发了激烈的争论。

达尔文的原始论点和进化渐进主义者支持的观点是物种会持续地改变,但非常缓慢,增量也很小。

TPO21阅读解析-Passage2

TPO21阅读解析-Passage2

Q1答案:A解析:option“选择,选项”,所以A的choice正确。

代入原文,提到尽管游牧民族能到处搬家,但到了农耕时代这个就很难,benefit和idea明显不合文意,如果只是experience“体验”的话,即使到了农耕时代experience也不难,所以experience不正确。

Q2答案:B解析:A的healthier lifestyle做关键词定位至最后一句,提到游牧生活更健康,所以A正确,不选;B的knowledge of plants and animals做关键词定位至第二句,原文提到在knowledge比较丰富的人们当中农业发展起来,但不能凭这个推出游牧生活的人知识少,所以B错误,可选;C的storage做关键词定位至第四句,提到农业需要develop storage method,所以可以看出hunting and gathering是不需要这种能力的,C正确,不选;D的specific location定位至倒数第二句,而且根据上题的答案,这个正确,不选。

Q3答案:D解析:therefore“因此”,所以正确答案是D的as a result。

此题简单,A“理论上说”B“明显”C“频繁”都不正确。

Q4答案:A解析:提问全段如何组织,看开头,注意,一开头作者就提到traditionally,这个词的出现意味着全段可能存在转折,看第二句就提到it was argued,这和第一句观点不同,所以答案是A,先提出,再批判。

Q5答案:C解析:注意allowing和due to的双重因果关系,温度上升使得resource丰富,再使得人口增长,所以答案是C,很好地重复了这个双重因果。

A少缺最终的结果,也就是人口;B的simultaneously错误;D弄错了前面两个原因之间的关系。

Q6答案:D解析:以fluctuate做关键词定位至最后一句,提到气候变化,先wet接着干旱,导致availability也跟着波动,所以导致resource波动的原因是气候的干湿,所以答案是D的rainfall变化。

Explaining Dinosaur Extinction Dinosaurs rapidly became extinct about 65 million years ago as part of a mass extinction known as the K-T event,because it is associated with a geological signature known as the K-T boundary,usually a thin band of sedimentation found in various parts of the world(K is the traditional abbreviation for the Cretaceous,derived from the German name Kreidezeit).Many explanations have been proposed for why dinosaurs became extinct.For example,some have blamed dinosaur extinction on the development of flowering plants,which were supposedly more difficult to digest and could have caused constipation or indigestion—except that flowering plants first evolved in the Early Cretaceous,about 60 million years before the dinosaurs died out.In fact,several scientists have suggested that the duckbill dinosaurs and homed dinosaurs,with their complex battery of grinding teeth,evolved to exploit this new resource of rapidly growing flowering plants Others have blamed extinction on competition from the mammals,which allegedly ate all the dinosaur eggs—except that mammals and dinosaurs appeared at the same time in the Late Triassic,about 190 million years ago,and there is no reason to believe that mammals suddenly acquired a taste for dinosaur eggs after 120 million years of coexistence Some explanations(such as the one stating that dinosaurs all died of diseases)fail because there is no way to scientifically test them,and they cannot move beyond the realm of speculation and guesswork. This focus on explaining dinosaur extinction misses an important point the extinction at the end of the Cretaceous was a global event that killed off organisms up and down the food chain.It wiped out many kinds of plankton in the ocean and many marine organisms that lived on the plankton at the base of the food chain.These included a variety of clams and snails,and especially the ammonites,a group of shelled squidlike creatures that dominated the Mesozoic seas and had survived many previous mass extinctions.The K-T event marked the end of the marine reptiles,such as the mosasaurs and the plesiosaurs,which were the largest creatures that had ever lived in the seas and which ruled the seas long before whales evolved.On land,there was also a crisis among the land plants,in addition to the disappearance of dinosaurs.So any event that can explain the destruction of the base of the food chain(plankton in the ocean,plants on land)can better explain what happened to organisms at the top of the food chain,such as the dinosaurs.By contrast,any explanation that focuses strictly on the dinosaurs completely misses the point The Cretaceous extinctions were a global phenomenon,and dinosaurs were just a part of a bigger picture. According to one theory,the Age of Dinosaurs ended suddenly 65 million years ago when a giant rock from space plummeted to Earth.Estimated to be ten to fifteen kilometers in diameter,this bolide(either a comet or an asteroid)was traveling at cosmic speeds of 20-70 kilometers per second,or 45,000-156,000 miles per hour.Sucha huge mass traveling at such tremendous speeds carries an enormous amount of energy.When the bolide struck this energy was released and generated a huge shock wave that leveled everything for thousands of kilometers around the impact and caused most of the landscape to burst into flames.The bolide struck an area of the Yucatan Peninsula of Mexico known as Chicxulub,excavating a crater 15-20 kilometers deep and at least 170 kilometers in diameter.The impact displaced huge volumes of seawater,causing much flood damage in the Caribbean.Meanwhile,the bolide itself excavated 100 cubic kilometers of rock and debris from the site,which rose to an altitude of 100 kilometers.Most of it fell back immediately,but some of it remained as dust in the atmosphere for months.This material,along with the smoke from the fires,shrouded Earth,creating a form of nuclear winter.According to computerized climate models,global temperatures fell to near the freezing point,photosynthesis halted,and most plants on land and in the sea died.With the bottom of the food chain destroyed,dinosaurs could not survive. paragraph 1 Dinosaurs rapidly became extinct about 65 million years ago as part of a mass extinction known as the K-T event,because it is associated with a geological signature known as the K-T boundary,usually a thin band of sedimentation found in various parts of the world(K is the traditional abbreviation for the Cretaceous,derived from the German name Kreidezeit).Many explanations have been proposed for why dinosaurs became extinct.For example,some have blamed dinosaur extinction on the development of flowering plants,which were supposedly more difficult to digest and could have caused constipation or indigestion—except that flowering plants first evolved in the Early Cretaceous,about 60 million years before the dinosaurs died out.In fact,several scientists have suggested that the duckbill dinosaurs and homed dinosaurs,with their complex battery of grinding teeth,evolved to exploit this new resource of rapidly growing flowering plants Others have blamed extinction on competition from the mammals,which allegedly ate all the dinosaur eggs—except that mammals and dinosaurs appeared at the same time in the Late Triassic,about 190 million years ago,and there is no reason to believe that mammals suddenly acquired a taste for dinosaur eggs after 120 million years of coexistence Some explanations(such as the one stating that dinosaurs all died of diseases)fail because there is no way to scientifically test them,and they cannot move beyond the realm of speculation and guesswork. 1.In paragraph 1,why does the author include a discussion of when flowering plants evolved? 【事实信息题】 A.To help explain why some scientists believe that the development of flowering plants led to dinosaur extinction。

Competition When several individuals of the same species or of several different species depend on the same limited resource,a situation may arise that is referred to as competition.The existence of competition has been long known to naturalists;its effects were described by Darwin in considerable petition among individuals of the same species(intraspecies competition),one of the major mechanisms of natural selection,is the concern of evolutionary petition among the individuals of different species(interspecies competition)is a major concern of ecology.It is one of the factors controlling the size of competing populations,and extreme cases it may lead to the extinction of one of the competing species.This was described by Darwin for indigenous New Zealand species of animals and plants,which died out when competing species from Europe were introduced. 当同一物种的不同个体或不同的物种都依靠同一有限资源时,这种情况往往会引发成所谓的竞争。

Early Children Education Preschools—educational programs for children under the age of five—differ significantly from one country to another according to the views that different societies hold regarding the purpose of early childhood education.For instance,in a cross-country comparison of preschools in China,Japan,and the United States,researchers found that parents in the three countries view the purpose of preschools very differently.Whereas parents in China tend to see preschools primarily as a way of giving children a good start academically,Japanese parents view them primarily as a way of giving children the opportunity to be members of a group.In the United States,in comparison,parents regard the primary purpose of preschools as making children more independent and self-reliant,although obtaining a good academic start and having group experience are also important. 由于不同社会持有的关于儿童早教目的观点的不同,学前班(5岁以下儿童的教育项目)的形式在不同国家也大不相同。

剑桥18 阅读test2 passage2解析摘要:1.引言2.森林管理的定义和重要性3.宾夕法尼亚的森林管理实践4.管理低质量木材的方法5.高质量树干的砍伐问题6.森林健康度的影响7.总结正文:1.引言森林是地球上最重要的生态系统之一,它为我们提供了氧气、清洁空气、水资源和生物多样性。

然而,随着人类活动的不断扩张,森林面临着严重的破坏和退化。

为了保护森林资源,人们开始采取各种措施进行森林管理。

本文将介绍剑桥18 阅读测试2 的Passage 2,该篇文章主要讲述了宾夕法尼亚的森林管理实践,探讨了如何通过管理低质量木材来促进森林的可持续发展。

2.森林管理的定义和重要性森林管理是指对森林资源进行科学、合理、有效的保护、培育、利用和修复的一系列活动。

其目的是为了维护森林生态平衡,提高森林生产力,保障森林资源可持续利用,促进人与自然和谐共生。

森林管理对于保护生物多样性、减缓气候变化、改善生态环境和促进经济发展具有重要意义。

3.宾夕法尼亚的森林管理实践宾夕法尼亚是美国著名的林业州,其森林资源丰富,森林覆盖率达到65%。

在森林管理方面,宾夕法尼亚采取了一系列有效的措施。

首先,他们制定了严格的森林采伐法规,限制了每年砍伐的树木数量,以保障森林资源的可持续利用。

其次,他们采用多样化的森林经营模式,包括天然林保护、人工林培育、森林生态旅游等,以提高森林的经济效益和生态效益。

最后,他们引入了高科技手段,如遥感技术、地理信息系统等,对森林资源进行实时监测和管理。

4.管理低质量木材的方法在宾夕法尼亚的森林管理实践中,管理低质量木材是一个重要环节。

低质量木材主要包括病虫害木材、变形木材、裂纹木材等。

这些木材的价值较低,如果直接丢弃,不仅会造成资源浪费,还会对环境产生负面影响。

因此,宾夕法尼亚采取了以下几种方法来管理低质量木材:a.将低质量木材加工成木屑,用作造纸、板材、生物质能等原料。

b.将低质量木材制作成家具、木工艺品等,以满足不同消费者的需求。

TPO20阅读解析-Passage2

Q1正确答案:C解析:momentous“重要的,重大的”,所以very important正确。

从单词本身看,意思上应该跟moment相关,“时刻的”,A和D明显不合文意。

原句提到这些变化对于本地稀疏的人口有什么影响,“常规的”影响明显不正确,答案是C。

Q2正确答案:B解析:EXCEPT题,排除法。

A/C/D都在第一段第一句中提到了,只有B没有提到,所以答案是B。

Q3正确答案:D解析:指代题,需要沿着提到的内容往前看,前一句提到由于农业和城镇的发展,人口成千上万,紧接着提到this change,说这个变化指的就是人口的增长,所以答案是D。

Q4正确答案:B解析:exploit“开采,开发,利用”,所以B的utilize正确。

原句提到当地人怎么样自然景观,之后举了很多例子,有放牧有打猎等等,都是在利用自然环境,所以是“利用”。

C“定居”和D“改善”都不正确;A选项不选,后面的例子说明不只是探索,所以答案是B。

Q5正确答案:A解析:根据这些例子找定位,提到定居点里包含很多通过贸易获得的外来物品,诸如……,所以列举的这些东西都是外来品,A是正确答案。

BCD都未提及。

Q6正确答案:D解析:cramped“局促的,狭窄的,难懂的”,所以confined正确。

原句提到在公元前9500年,一个村子的人都在一个什么样的住处里,根据句义,这里强调的是比较小,所以其他的都不合文意。

而且extend刚好和confine是相反的意思,所以D是答案。

Q7正确答案:D解析:Abu Hureyra做关键词定位至第一句的后半句和第二句的前半句,一直在说AH,接着往下看,提到接下来的1500年里,他们所在的地方气候温暖,种子丰富,所以答案是D,C与原文相反;A和B选项的内容在此并未提及。

Q8正确答案:C解析:shift“转变,转换,倒班”,所以最接近的答案是change。

原句提到漂浮的样品使得植物学家研究植物集群习惯的什么就好像在显微镜下看风景一样,风景是会变的,所以答案是change。

剑桥18 阅读test2 passage2解析(实用版)目录1.引言:介绍剑桥 18 阅读 test2 passage2 的背景和主题2.文章结构:分析文章的各个部分,包括宾夕法尼亚的森林管理和森林可持续性3.森林管理的问题:详述文章中提到的森林管理问题,包括低质量木材的管理和砍伐高质量树干4.森林可持续性的意义:解释森林可持续性对环境和经济的重要性5.结论:总结文章的主要观点,并探讨森林管理对实现森林可持续性的影响正文剑桥 18 阅读 test2 passage2 主要讨论了宾夕法尼亚的森林管理问题和森林可持续性的重要性。

文章从分析森林管理的各个方面入手,详细阐述了森林管理中存在的问题,以及这些问题对森林可持续性的影响。

文章首先介绍了宾夕法尼亚的森林管理情况。

宾夕法尼亚拥有丰富的森林资源,然而,在过去的几十年里,由于不良的森林管理,导致森林质量不断下降。

文章中提到的一个例子是低质量木材的管理。

在这里,作者指出,樱桃树对家具制造商来说非常有价值,但对庄园主来说,树干才是真正的价值所在。

这就说明了不同人对树木价值的看法是不同的。

另一个例子是砍伐高质量树干。

高质量的树干被砍伐后,留下的是经济价值较低的树木,这些树木会与价值更高的树木竞争生长资源,遮蔽更为理想的更新生长,并降低林分的健康度,使其更容易受到疾病的侵袭。

接下来,文章探讨了森林可持续性的意义。

森林可持续性是指在保护环境和促进经济发展的前提下,合理利用森林资源。

森林可持续性对环境和经济的重要性不言而喻。

森林不仅能为我们提供清洁的空气和水源,还能为我们提供木材和其他生物资源。

然而,由于不良的森林管理,森林资源正遭受严重的破坏。

因此,实现森林可持续性对于保护我们的环境和经济至关重要。

最后,文章总结了森林管理对实现森林可持续性的影响。

文章指出,良好的森林管理有助于实现森林可持续性,而不良的森林管理则会破坏森林资源。

通过本文的讨论,我们可以看到,森林管理在实现森林可持续性方面发挥着关键作用。

TPO53托福阅读Passage2原文文本Sounds In The FilmListen to part of a lecture in a film studies class.Professor: Nowadays we take sound in films for granted. I mean you still might see black and white films occasionally. But you'll hardly ever see silent films anymore.So it's interesting to note that the use of recorded sound was originally controversial. And some directors, uh, some filmmakers even thought it shouldn't be used, that it would destroy the purity of cinema, somehow reverse all the progress that had been made in the art of cinema. Abby?Abby: What about all the sounds you hear in some silent movies? Like, you know, a loud sound when somebody falls down or something?Professor: Okay, you're talking about a soundtrack added much later, which has over time become part of the film we know. But this recorded track didn't exist then.And it's not that most people didn't want sound in films. It's just that the technology wasn't available yet. Don't forget that instead of recorded sound, there was often live music that accompanied movies in those days, like a piano player or a larger orchestra in the movie theater.Also, think of the stage, the live theater, it has used wonderfulsound effects for a long time. And if wanted, these could be produced during the viewing of a film. You know, the rolling of drums for thunder or whatever. But that wasn't as common.Oh, and another thing, that they might have in movie theaters in the early days, was a group of live actors reading the parts to go along with the film, or, and this seems a particularly bad idea to us now, one person narrating the action, an early example of a long tradition of movie producers, the ones concerned mostly about making money, not having much confidence in their audience, thinking that people somehow couldn't follow the events otherwise.So, it finally became possible to play recorded sound as part of the film in the 1920s. Trouble was, it wasn't always used to very good effect. First it was, you know, amazing to see somebody's mouth move at the same time you hear the words, or hear a door close when you see it closing on screen.But that luster wears off, of course. And if you're a director, a filmmaker, what's the next step?Abby: Well, you sound to enhance the movie right? Bring something more to it that wasn’t possible?Professor: Yes. That’s exactly what directors, who were more interested in cinema as art, not commerce, were thinking.But they also predicted that there would be a problem that sound would be misused and, boy, was it ever.Because the commercial types, the producers and so on, were thinking, “Okay. Now that sound is possible, let's talk as much as possible and forget about the fact that we're making a movie, that we have this powerful visual medium.”So many of the films of the twenties were basically straight adaptations of successful shows from the stage, theatre. Thename they used for sound films then was “talking films” and that was on the mark, since, well, all they pretty much did was talk and talk.So, remedy? Well what was proposed by a number of filmmakers and theorists was the creative expressive use of sound, what they generally called nonsynchronous sound.Okay, synchronous sound means basically that what we hear is what we see. Everything on the soundtrack is seen on the screen. A nd everything was recorded simultaneously, which… Well, since the sound technicians working on films often had experience with live radio that made sense to them. Recording the sound separately and adding it in afterward? Well, that idea was less obvious.Anyway synchronous sound means the source of the sound is the image on the screen.Nonsynchronous sound then is…Abby: The sound doesn't match the picture?Professor: Right. Now we can look at this in various ways. But let's take it as literally as possible.Music, unless we see the radio or the orchestra, that's nonsynchronous. If the camera shot is of the listener rather than the speaker that's nonsynchronous. If we hear, say, background sounds that aren't on the screen, that's nonsynchronous.So, that doesn't seem so radical, does it? But again, those early producers didn't think their audiences could keep up with this.Abby: Excuse me, but did you say earlier that some filmmakers actually advocated not using sound at all?Professor: Well, yes. But that was a bit of an exaggeration, I guess. What I meant to say was that some filmmakers thought that the way the film sound was actually used was setting the artof filmmaking back.But everyone agreed that sounds solved some very difficult issues and offered potentially exciting tools.TPO53托福阅读Passage2题目Question 1 of 5What is the lecture mainly about?A.

TPO4托福阅读Passage2原文+题目+答案解析TPO4托福阅读Passage2原文文本Cave Art in EuropeThe earliest discovered traces of art are beads and carvings, and then paintings, from sites dating back to the Upper Paleolithic period. We might expect that early artistic efforts would be crude, but the cave paintings of Spain and southern France show a marked degree of skill. So do the naturalistic paintings on slabs of stone excavated in southern Africa. Some of those slabs appear to have been painted as much as 28,000 years ago, which suggests that painting in Africa is as old as painting in Europe. But painting may be even older than that. The early Australians may have painted on the walls of rock shelters and cliff faces at least 30,000 years ago, and maybe as much as 60,000 years ago.The researchers Peter Ucko and Andree Rosenfeld identified three principal locations of paintings in the caves of western Europe: (1) in obviously inhabited rock shelters and cave entrances; (2) in galleries immediately off the inhabited areas of caves; and (3) in the inner reaches of caves, whose difficulty of access has been interpreted by some as a sign that magical-religious activities were performed there.The subjects of the paintings are mostly animals. The paintings rest on bare walls, with no backdrops or environmental trappings. Perhaps, like many contemporary peoples, UpperPaleolithic men and women believed that the drawing of a human image could cause death or injury, and if that were indeed their belief, it might explain why human figures are rarely depicted in cave art. Another explanation for the focus on animals might be that these people sought to improve their luck at hunting. This theory is suggested by evidence of chips in the painted figures, perhaps made by spears thrown at the drawings. But if improving their hunting luck was the chief motivation for the paintings, it is difficult to explain why only a few show signs of having been speared. Perhaps the paintings were inspired by the need to increase the supply of animals. Cave art seems to have reached a peak toward the end of the Upper Paleolithic period, when the herds of game were decreasing.The particular symbolic significance of the cave paintings in southwestern France is more explicitly revealed, perhaps, by the results of a study conducted by researchers Patricia Rice and Ann Paterson. The data they present suggest that the animals portrayed in the cave paintings were mostly the ones that the painters preferred for meat and for materials such as hides. For example, wild cattle (bovines) and horses are portrayed more often than we would expect by chance, probably because they were larger and heavier (meatier) than other animals in the environment. In addition, the paintings mostly portray animals that the painters may have feared the most because of their size, speed, natural weapons such as tusks and horns, and the unpredictability of their behavior. That is, mammoths, bovines, and horses are portrayed more often than deer and reindeer. Thus, the paintings are consistent with the idea that the art is related to the importance of hunting in the economy of Upper Paleolithic people. Consistent with this idea, according to theinvestigators, is the fact that the art of the cultural period that followed the Upper Paleolithic also seems to reflect how people got their food. But in that period, when getting food no longer depended on hunting large game animals (because they were becoming extinct), the art ceased to focus on portrayals of animals.Upper Paleolithic art was not confined to cave paintings. Many shafts of spears and similar objects were decorated with figures of animals. The anthropologist Alexander Marshack has an interesting interpretation of some of the engravings made during the Upper Paleolithic. He believes that as far back as 30,000 B.C., hunters may have used a system of notation, engraved on bone and stone, to mark phases of the Moon. If this is true, it would mean that Upper Paleolithic people were capable of complex thought and were consciously aware of their environment. In addition to other artworks, figurines representing the human female in exaggerated form have also been found at Upper Paleolithic sites. It has been suggested that these figurines were an ideal type or an expression of a desire for fertility.TPO4托福阅读Passage2题目Question 1 of 14The word “marked ” in the passage is closest in meaning toA. considerableB. surprisingC. limitedD. adequateQuestion 2 of 14Paragraph 1 supports which of the following statementsabout painting in Europe?A. It is much older than painting in Australia.B. It is as much as 28,000 years old.C. It is not as old as painting in southern Africa.D. It is much more than 30,000 years old.Question 3 of 14The word “principal ” in the passage is closest in meaning toA. majorB. likelyC. well protectedD. distinctQuestion 4 of 14According to paragraph 2, what makes some researchers think that certain cave paintings were connected with magical-religious activities?A. The paintings were located where many people could easily see them, allowing groups of people to participate in the magical-religious activities.B. Upper Paleolithic people shared similar beliefs with contemporary peoples who use paintings of animals in their magical-religious rituals.C. Evidence of magical-religious activities has been found in galleries immediately off the inhabited areas of caves.D. The paintings were found in hard-to-reach places away from the inhabited parts of the cave.Question 5 of 14The word “trappings ” in the passage is closest in meaning toA. conditionsB. problemsC. influencesD. decorationsQuestion 6 of 14Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.A. Upper Paleolithic people, like many contemporary peoples, believed that if they drew a human image in their cave art, it would cause death or injury.B. Many contemporary people believe that the drawing of a human image can cause death or injury, so they, like Upper Paleolithic people, rarely depicted human figures in their cave art.C. If Upper Paleolithic people, like many contemporary peoples, believed that the drawing of a human image could cause death or injury, this belief might explain why human figures are rarely depicted in cave art.D. Although many contemporary peoples believe that the drawing of a human image can cause death or injury, researchers cannot explain why Upper Paleolithic people rarely depicted human figures in their cave art.Question 7 of 14According to paragraph 3, scholars explained chips in the painted figures of animals by proposing thatA. Upper Paleolithic artists used marks to record the animals they had seenB. the paintings were inspired by the need to increase the supply of animals for huntingC. the artists had removed rough spots on the cave wallsD. Upper Paleolithic people used the paintings to increase their luck at huntingQuestion 8 of 14Why does the author mention that Upper Paleolithic cave art seemed to have “reached a peak toward the end of t he Upper Paleolithic period, when the herds of game were decreasing ”?A. To argue that Upper Paleolithic art ceased to include animals when herds of game became scarceB. To provide support for the idea that the aim of the paintings was to increase the supply of animals for huntingC. To emphasize the continued improvement in the quality of cave art throughout the Upper Paleolithic periodD. To show the direct connection between the decrease in herds of game and the end of the Upper Paleolithic period Question 9 of 14According to paragraph 4, scholars believe that wild cattle, horses, and mammoths are the animals most frequently portrayed in cave paintings for all of the following reasons EXCEPT:A. These animals were difficult to hunt because their unpredictable behavior.B. People preferred these animals for their meat and for their skins.C. The painters admired the beauty of these large animals.D. People feared these animals because of their size and speed.Question 10 of 14According to paragraph 4, which of the following may best represent the attitude of hunters toward deer and reindeer in the Upper Paleolithic period?A. Hunters did not fear deer and reindeers as much as they did large game animals such as horses and mammoths.B. Hunters were not interested in hunting deer and reindeer because of their size and speed.C. Hunters preferred the meat and hides of deer and reindeer to those of other animals.D. Hunters avoided deer and reindeer because of their natural weapons, such as horns.Question 11 of 14According to paragraph 4, what change is evident in the art of the period following the Upper Paleolithic?A. This new art starts to depict small animals rather than large ones.B. This new art ceases to reflect the ways in which people obtained their food.C. This new art no longer consists mostly of representations of animals.D. This new art begins to show the importance of hunting to the economy.Question 12 of 14According to paragraph 5, which of the following has been used as evidence to suggest that Upper Paleolithic people were capable of complex thought and conscious awareness of their environment?A.

Latitude and Biodiversity When we look at the way in which biodiversity(biological diversity)is distributed over the land surface of the planet,we find that it is far from even.The tropics contain many more species overall than an equivalent area at the higher latitudes.This seems to be true for many different groups of animals and plants. Why is it that higher latitudes have lower diversities than the tropics?Perhaps it is simply a matter of land area.The tropics contain a larger surface area of land than higher latitudes—a fact that is not always evident when we examine commonly used projections of Earth’s curved surface,since this tends to exaggerate the areas of land in the higher latitudes—and some biogeographers regard the differences in diversity as a reflection of this effect.But an analysis of the data by biologist Klaus Rohde does not support this explanation.Although area may contribute to biodiversity,it is certainly not the whole story;otherwise,large landmasses would always be richer in species. Productivity seems to be involved instead,though perhaps its influence is indirect.Where conditions are most suitable for plant growth—that is,where temperatures are relatively high and uniform and where there is an ample supply of water—one usually finds large masses of vegetation.This leads to a complex structure in the layers of plant material.In a tropical rain forest,for example,a very large quantity of plant material builds up above the surface of the ground.There is also a large mass of material,developed below ground as root tissues,but this is less apparent.Careful analysis of the above ground material reveals that it is arranged in a series of layers,the precise number of layers varying with age and the nature of the forest.The arrangement of the biological mass("biomass")of the vegetation into layered forms is termed its“structure”(as opposed to its“composition,”which refers to the species of organisms forming the community).Structure is essentially the architecture of vegetation,and as in the case of tropical forests,it can be extremely complicated.In a mature floodplain tropical forest in the Amazon River basin,the canopy(the uppermost layers of a forest,formed by the crowns of trees)takes on a stratified structure.There are three clear peaks in leaf cover at heights of approximately 3,6,and 30 meters above the ground;and the very highest layer,at 50 meters,corresponds to the very tall trees that stand free of the main canopy and form an open layer of their own.So,such a forest contains essentially four layers of canopy.Forests in temperate lands often have just two canopy layers,so they have much less complex architecture. Structure has a strong influence on the animal life inhabiting a site.It forms the spatial environment within which an animal feeds,moves around shelters,lives,andbreeds.It even affects the climate on a very local level(the"microclimate")by influencing light intensity,humidity,and both the range and extremes of temperature.An area of grassland vegetation with very simple structure,for example,has a very different microclimate at the ground level from that experienced in the upper canopy.Wind speeds are lower,temperatures are lower during the day(but warmer at night),and the relative humidity is much greater near the ground.The complexity of the microclimate is closely related to the complexity of structure in vegetation,and generally speaking,the more complex the structure of vegetation,the more species of animal are able to make a living there.The high plant biomass of the tropics leads to a greater spatial complexity in the environment,and this leads to a higher potential for diversity in the living things that can occupy a region.The climates of the higher latitudes are generally less favorable for the accumulation of large quantities of biomass;hence,the structure of vegetation is simpler and the animal diversity is consequently lower. paragraph 1 When we look at the way in which biodiversity(biological diversity)is distributed over the land surface of the planet,we find that it is far from even.The tropics contain many more species overall than an equivalent area at the higher latitudes.This seems to be true for many different groups of animals and plants. 1.The word“distributed”in the passage is closest in meaning to A.represented B.collected C.spread D.managed 2.The word“overall”in the passage is closest in meaning to A.considered as a whole B.to some degree C.possibly D.evidently paragraph 2。

PASSAGE 2The geology of the Earth's surface is dominated by the particular properties of water. Present on Earth in solid, liquid, and gaseous states, water is exceptionally reactive. It dissolves, transports, and precipitates many chemical compounds and is constantly modifying the face of the Earth.Evaporated from the oceans, water vapor forms clouds, some of which are transported by wind over the continents. Condensation from the clouds provides the essential agent of continental erosion: rain. Precipitated onto the ground, the water trickles down to form brooks(小溪), streams, and rivers, constituting what are called the hydrographic network. This immense polarized network channels the water toward a single receptacle (容器): an ocean. Gravity dominates this entire step in the cycle because water tends to minimize its potential energy by running from high altitudes toward the reference point, that is, sea level.The rate at which a molecule of water passes though the cycle is not random but is a measure of the relative size of the various reservoirs. If we define residence time as the average time for a water molecule to pass through one of the three reservoirs —atmosphere, continent, and ocean — we see that the times are very different. A water molecule stays, on average, eleven days in the atmosphere, one hundred years on a continent and forty thousand years in the ocean. This last figure shows the importance of the ocean as the principal reservoir of the hydrosphere but also the rapidity of water transport on the continents.A vast chemical separation process takes places during the flow of water over the continents. Soluble ions such as calcium, sodium(钠), potassium(钾), and some magnesium(镁) are dissolved and transported. Insoluble ions such as aluminum, iron, and silicon stay where they are and form the thin, fertile skin of soil on which vegetation can grow. Sometimes soils are destroyed and transported mechanically during flooding. The erosion of the continents thus results from two closely linked and interdependent processes, chemical erosion and mechanical erosion. Their respective interactions and efficiency depend on different factors.1.翻译地球表面的地质情况受水的特有的性质控制。

在地球上以固态、液态和气态存在的水异常活跃。

水溶解、运输、沉淀很多化合物,并不断的更改地球的外观。

从大洋中蒸发出的水蒸气形成云,云被风在大陆传送。

云的冷凝为大陆侵蚀提供了必要的原动力—雨。

水在地面上凝结,形成细流、小溪、河流,构成水的循环网。

这种巨大的、分化的网络引导着水流向唯一的容器—海洋。

地心引力控制这个循环中的全部步骤,因为水趋向于减小势能的方向流动,从高空向参考点,即海平面。

一分子水循环一周的速度不是随机的,而是一个各种各样的汇集地间的相对大小的可测量标准。

如果我们定义停留时间是一个水分子通过三种汇集地—大气、大陆、大洋—之一的平均时间,我们发现停留时间是不同的。

平均起来,水分子在大气中停留11天,在大陆上停留100年,在大洋中停留4万年。

最后一个数据不仅显示了大洋作为最重要的水循环汇集处的重要性,还显示了水在大路上运输的很快。

巨大的化学分离过程发生在水在大陆上的流动过程中。

可溶离子,如钙、钠、钾及部分镁被溶解并带走。

不可溶的离子,如铝、铁和硅沉积下来,形成稀少的、富饶的、能够生长植物的地表。

有时土壤机械的在洪水中被破坏并带走。

大陆侵蚀产生于两个紧密连接给互相依存的过程,化学侵蚀和物理侵蚀。

它们各自的配合与效能受不同的因素控制。
