新东方在线为大家精心整理了托福黄金阅读及答案之威廉·史密斯的相关内容,分享给大家,供大家参考,希望对大家有所帮助!
In 1769 in a little town in Oxfordshire, England, a child with the very ordinary name of William Smith was born into the poor family of a village blacksmith. He received rudimentary village schooling but mostly he roamed his uncle's farm collecting the fossils that were so abundant in the rocks of the Cotswold hills.When he grew older William Smith taught himself surveying from books he bought with his small savings and at the age of eighteen he was apprenticed to a surveyor of the local parish. He then proceeded to teach himself geology and when he was twenty-four,he went to work for the company that was excavating the Somerset Coal Canal in the south of England. This was before the steam locomotive, and canal building was at its height.The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals. This job gave Smith an opportunity to study the fresh rock outcrops created by the newly dug canal. He later worked on similar jobs across the length and breadth of England all the while studying the newly revealed strata and collecting all the fossils he could find.Smith used mail coaches to travel as much as 10000 miles per year.In 1815 he published the first modern geological map “A Map of the Strata of England and Wales with a Part of Scotland”, a map so meticulously researched that it can still be used today.

In 1831 when Smith was finally recognized by the Geological Society of London as the “father of English geology”, it was not only for his maps but also for something even more important.Ever since people had begun to catalog the strata in particular outcrops, there had been the hope that these could somehow be used to calculate geological time.But as more and more accumulations of strata were cataloged in more and more places, it became clear that the sequences of rocks sometimes differed from region to region and that no rock type was ever going to become a reliable time marker throughout the world. Even without the problem of regional differences, rocks present a difficulty as unique time markers Quartz is quartz-a silicon ion surrounded by four oxygen ions-there’s no difference at all between two-million-year-old Pleistocene quartz and Cambrian quartz created over 500 million years ago.
As he collected fossils from strata throughout England, Smith began to see that the fossils told a different story from the rocks particularly in the younger strata the rocks were often so similar that he had trouble distinguishing the strata, but he never had trouble telling the fossils apart. While rock between two consistent strata might in one place be shale and in another sandstone, the fossils in that shale or sandstone were always the same. Some fossils endured through so many millions of years that they appear in many strata, but others occur only in a few strata, and a few species had their births and extinctions within one particular stratum. Fossils are thus identifying markers for particular periods in Earth's history.
Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging: certain fossils always appear in more ancient sediments, while others begin to be seen as the strata become more recent. By following the fossils, Smith was able to put all the strata of England's earth into relative temporal sequence. About the same time, Georges Cuvier made the same discovery while studying the rocks around Paris. Soon it was realized that this principle of faunal (animal) succession was valid not only in England or France but virtually everywhere. It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna. Limestone may be found in the Cambrian or 300 million years later in the Jurassic strata but a trilobite-the ubiquitous marine arthropod that had its birth in the Cambrian-will never be found in Jurassic strata, nor a dinosaur in the Cambrian.
Paragraph 1: In 1769 in a little town in Oxfordshire, England, a child with the very ordinary name of William Smith was born into the poor family of a village blacksmith. He received rudimentary village schooling but mostly he roamed his uncle's farm collecting the fossils that were so abundant in the rocks of the Cotswold hills.When he grew older William Smith taught himself surveying from books he bought with his small savings and at the age of eighteen he was apprenticed to a surveyor of the local parish. He then proceeded to teach himself geology and when he was twenty-four, he went to work for the company that was excavating the Somerset Coal Canal in the south of England.
1. The word rudimentary in the passage is closest in meaning to
○thorough
○strict
○basic
○occasional
2. According to paragraph 1 which of the following statements about William Smith is NOT true?
○Smith learned surveying by reading and by apprenticing for a local surveyor
○Smith’s family lived in a small English town and possessed little wealth.
○Smith learned about fossils from books he borrowed from his uncle.
○Smith eventually left his village to work on the excavation of an English canal.
Paragraph 2: This was before the steam locomotive, and canal building was at its height. The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals. This job gave Smith an opportunity to study the fresh rock outcrops created by the newly dug canal. He later worked on similar jobs across the length and breadth of England all the while studying the newly revealed strata and collecting all the fossils he could find.Smith used mail coaches to travel as much as 10000 miles per year.In 1815 he published the first modern geological map “A Map of the Strata of England and Wales with a Part of Scotland”, map so meticulously researched that it can still be used today.
3. Which of the following can be inferred from paragraph 2 about canal building?
○ Canals were built primarily in the south of England rather than in other regions.
○ Canal building decreased after the steam locomotive was invented.
○ Canal building made it difficult to study rock strata which often became damaged in the process.
○ Canal builders hired surveyors like Smith to examine exposed rock strata.
4.Accordingto paragraph2,which of the following is true of the map published by William Smith?
○It indicates the locations of England's major canals
○It became most valuable when the steam locomotive made rail travel possible
○The data for the map were collected during Smith’s work on canals
○It is no longer regarded as a geological masterpiece
5. The word meticulously in the passage is closest in meaning to
○carefully
○quickly
○frequently
○obviously
Paragraph 3: In 1831 when Smith was finally recognized by the Geological Society of London as the “father of English geology”, was not only for his maps but also for something even more important.Ever since people had begun to catalog the strata in particular outcrops, there had been the hope that these could somehow be used to calculate geological time.But as more and more accumulations of strata were cataloged in more and more places, it became clear that the sequences of rocks sometimes differed from region to region and that no rock type was ever going to become a reliable time marker throughout the world.Even without the problem of regional differences, rocks present a difficulty as unique time markers Quartz is quartz—a silicon ion surrounded by four oxygen ions—there’s no difference at all between two-million-year-old Pleistocene quartz and Cambrian quartz created over 500 million years ago.
6. Which 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.
○The discovery of regional differences in the sequences of rocks led geologists to believe that rock types could someday become reliable time markers.
○Careful analysis of strata revealed that rocks cannot establish geological time because the pattern of rock layers varies from place to place.
○Smith's catalogs of rock strata indicated that the sequences of rocks are different from place to place and from region to region.
○Because people did not catalog regional differences in sequences of rocks. It was believed that rocks could never be reliable time markers
7. Why does the author use the phrase “Quartz is quartz"?
○To describe how the differences between Pleistocene and Cambrian quartz reveal information about dating rocks
○To point out that the chemical composition of quartz makes it more difficult to date than other rocks
○To provide an example of how regional differences in rock sequences can make a particular rock difficult to date
○To explain that rocks are difficult to use for dating because their chemical compositions always remain the same over time
Paragraph 4: As he collected fossils from strata throughout England, Smith began to see that the fossils told a different story from the rocks. Particularly in the younger strata the rocks were often so similar that he had trouble distinguishing the strata, but he never had trouble telling the fossils apart.While rock between two consistent strata might in one place be shale and in another sandstone, the fossils in that shale or sandstone were always the same.Some fossils endured through so many millions of years that they appear In many strata,but others occur only in a few strata, and a few species had their births and extinctions within one particular stratum.Fossils are thus identifying markers for particular periods in Earth's history.
8.According to paragraph 4,it was difficult for Smith to distinguish rock strata because
○the rocks from different strata closely resembled each other
○he was often unable to find fossils in the younger rock strata
○their similarity to each other made it difficult for him to distinguish one rock type from another
○the type of rock between two consistent strata was always the same
9. The word endured in the passage is closest in meaning to
○vanished
○developed
○varied
○survived
Paragraph 5: Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging:certain fossils always appear in more ancient sediments while others begin to be seen as the strata become more recent. By following the fossils, Smith was able to put all the strata of England's earth into relative temporal sequence. About the same time, Georges Cuvier made the same discovery while studying the rocks around Paris. Soon it was realized that this principle of faunal (animal) succession was valid not only in England or France but virtually everywhere. It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna. Limestone may be found in the Cambrian or-300 million years later-in the Jurassic strata but a trilobite—the ubiquitous marine arthropod that had its birth in the Cambrian—will never be found in Jurassic strata, nor a dinosaur in the Cambrian.
10. The word “virtually” in the passage is closest in meaning to
○possibly
○absolutely
○surprisingly
○nearly
11. Select the TWO answer choices that are true statements based upon the discussion of the principle of faunal succession in paragraph 5. To receive credit, you must select TWO answers.
○It was a principle that applied to fauna but not to flora.
○It was discovered independently by two different geologists,
○It describes how fossils are distributed in rock strata
○It explains why plants and animals undergo transformations through time.
12. In mentioning "trilobite”, the author is making which of the following points?
○Fossils cannot be found in more than one rock stratum.
○Faunal succession can help put rock layers in relative temporal sequence.
○Faunal succession cannot be applied to different strata composed of the same kind of rock.
○The presence of trilobite fossils makes it difficult to date a rock.
Paragraph 5: Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging:certain fossils always appear in more ancient sediments, while others begin to be seen as the strata become more recent. By following the fossils.Smith was able to put all the strata of England's earth into relative temporal sequence.

13.Look at the four squares that indicate where the following sentence could be added to the passage The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world.
Where would the sentence best fit?
14. William Smith’s contributions to geology have increased our knowledge of the Each’s history.

威廉·史密斯
在1769 年英国牛津郡的一个小镇上,一个小男孩出生在村里一户穷铁匠家,他的名字很普通,叫做威廉• 史密斯。史密斯只在村里的学校接受了最基本的教育,大部分的时间都是在他叔叔的农场里搜寻化石,这些化石 在科茨沃尔德山的岩石里是很常见的。长大后,他开始用微薄的积蓄买书自学测量,18 岁的时,史密斯成为了 当地教区测量员的助理。后来,他又自学了地质学,24 岁的时,他开始为挖掘英格兰南部Somerset Coal 运河那 家公司工作。
这些事情都发生在蒸汽火车发明之前,运河建筑正处于顶峰时期。他工作的那家公司致力于开掘一条运河来 运输煤矿,需要测量员帮助他们探寻值得挖掘的煤矿所在地,并为他们决定最佳的运河路线。这份工作为史密斯 提供了一个机会,使他能够接触和学习那些因为运河开掘而露出地面的新鲜岩层。后来他仍从事类似的工作,行 便全国,不断地研究那些新出现的地层,同时收集他所能发现的化石。史密斯乘着邮件马车每年行进将近10000 英里。1815 年,他绘制了第一张现代地质学地图——英格兰威尔士及苏格兰部分地区地层地图,这张地质地图 绘制得非常精确,直到现在仍有参考价值。
到了1831 年,史密斯最终被伦敦地质学会认可,并赋予他“英国地质学之父”的称号,这不仅仅是因为那 张地图,而且是为了其他更重要的原因。从人们开始对露出地面的特殊岩层进行分类的时候起,大家就开始认为 这些岩石可能会以某种方式被用于计算地质年代。但是,随着各地越来越多的岩层积累和分类,岩层顺序也因地 区的不同而不同,因此,全世界没有一种特定的岩层能被认作是划分地质年代的标志。即便排除区域差异的影响, 人们面对岩石,还是存在一道难题,石英作为一种独特的时间标记——四个氧离子包围一个硅离子的化合物,而 两百万年前的更新世石英和五亿年前形成的寒世纪的石英并无差别,这让人们束手无措。
史密斯在全英国的岩层中不断收集化石,后来他发现化石所反映的史实和岩石反映的完全不同,尤其是那些 新产生的地层里的岩石,这些岩石非常类似,不易于区分地层。而区分其中的化石对史密斯来说简直就是轻而易 举。在同层的地层中发现的岩石可能在这片地层中属于泥板岩,而在另一片地层中可能是砂岩,而在那些泥板岩 或者砂岩中的化石往往都是一样的。有的化石经历了数百年万之久,它们存在于很多地层中间,但有的化石只存 在于部分地层,还有一部分化石从出现至灭绝都只出现在一个特定的岩层中。因此,化石才是真正划分地球历史 特定年代的指针。
史密斯不仅可以通过岩石中包含的化石来识别地层,而且可以看出他们显露出来的模式:一些特定的化石往 往出现在更为久远的沉积物当中,而其他的化石则可以在距今年代较近的地层中发现。通过追踪化石,史密斯将 英国范围内所有的地层进行了彼此出现时间的排序。同时,乔治居维叶在研究巴黎周围的岩石时也作出了同样的 发现。很快人们就开始认识到,这种动物物种的延续性是符合逻辑的,不仅仅是在英国、法国,而实际上在全世 界范围都是适用的。事实上,这一原则同样适用于证实植物的延续性,因为植物和动物一样,它们的化石也显示 了时间的推移。人类有可能在侏罗纪时期的地层中发现寒世纪或者三亿年后的石灰岩,但绝不可能在侏罗纪时期 地层中发现三叶虫化石(三叶虫是寒世纪非常普遍的水生节肢动物),也不可能发现寒世纪时期的恐龙化石。
