3.Interviewer-------- Why is English so important?David------- Well, English is so important primarily because so many people speak it and use it, so it has now become the lingua franca in the world in a way that we’ve never seen before. We’ve never had a world language of this kind before. So people are learning it not just to be able tocommunicate with native speakers, but also with speakers of other language around world.Interviewer-------And why has it become that dominant language?David------I think the reason for that is actually very complicated, although in the twentieth century, we can just see that it’s the rise of the US military and consumer power. I mean the technology, all the big developments in technology largely came from the US. So all of these developments actually were produced within the English language, and people had to learn English in order to understand them, or to benefit from them. The Internet is only one example of that kind. Once a language has got into that position of dominance, it’s actually very different to shift it. So we could be seeing the emergence of other big languages in the world becoming more important than they have been, like Spanish, but it’s unlikely that they’re going to shift the English from its position of dominance.36. English is important, according to David, __________________________. A). because it has become a world language B). because so many people speak and use it C). because a lot of people are learning it D). because it is the lingua franca37. English has become the dominant language in the world________________________. A). because it has always been the way B). for a reason that is very complicated C). only in the 20th century D). for no reasons38. English became the dominant language in the 20th century_________________________. A). in the USAB). because of the increase in American consumer powerC). because developments in technology came mainly from USA. D). all over the world.39. People had to learn English______________________.A). because developments in technology were made by English speakers B). because they needed to understand the new developments in technology C). to use the InternetD). to speak with native Americans40. David thinks that__________________________.A). it will be easy for another language to become dominant B). English will not always be the dominant languageC). it will not be easy for another language to become dominant D). English will be the dominant language

    The Bilingual Brain
    When Karl Kim immigrated to the United States from Korea as a teenager,he had a hard time learning English.Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language.As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York Their work led to an important discovery.They found evidence that children and adults don't use the same parts ofthe brain when they learn a second language.
    The researchers used an instrument called an MRI(magnetic resonance imaging)scanner to study the brains of two groups of bilingual people.One group consisted of those who had learned a second language as children.The other consisted of people who,like Kim,learned their second language later in lite.Peoplefrom both groups were placed inside the MRI scanner ,This allowed Kim and Hirsch to see which parts of thebrain were getting more blood and were more active.They asked people from both groups to think about whatthey had done the day before ,first in one language and then the other.They couldn't speak out loudbecause any movement would disrupt(干扰)the scanning.
    Kim and Hirsch looked specifically at two language centers in the brain-Broca' s area, which isbelieved to control speech production,and Wernicke's area,which is thought to process meaning.Kim andHirsch found that both groups of people used the same part of Wernicke's area no matter what language theywere speaking.But their use of Broca's area was different.
    People who learned a second language as children used the same region in Broca's area for both tneir first and second languages.People who learned a second language later in life used a different part of Broca's area for their second language.How does Hirsch explain this difference?Hirsch believes that when language is first being programmed in young children,their brains may mix the sounds and structures of all languages in the same area.Once that programming is complete,the processing of a new language must be taken over by adifferent part of the brain.
    A second possibility is simply that we may acquire languages differently as children than we do asadults.Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.And that is very different from learning a language in a high school or college class.

    Kim and Hirsch find that children______.
    A: use the same region in Broca's area to learn their first and second language
    B:learn a second language slower than adults
    C:are better at acquiring the sound system of a second language than adults
    D:use special parts of the brain to program the structures of their first language

    答案:A
    解析:
    由文章第一段最后一句可知,他们发现证据表明儿童和成人在学习第二语言时使用的是大脑的不同区域,故选B。
    由文章第二段第一句可知,研究人员使用一种名为MRI扫描仪的设备来研究这两组学习双语人群的大脑活动,故选C。
    由文章第三段第一句可知,这两个中枢的作用分别是控制语言产出和处理语言意义,这属于中枢的功能,故选B。
    由文章第四段第一句可知,从儿童时期就开始学习第二语言的人在学习第二语言时所使用的大脑布洛卡区域和学母语时相同,故选A。
    文章最后一段主要讲的是儿童和成年人学习语言的方式和手段不同,尤其提到了母亲在教授儿童语言时的独特方式:触觉、视觉和听觉等多种手段并用。这与以后学校的语言学习手段有着很大不同。我们可以推断出母亲很擅长教授孩子语言,尤其从“Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.”这句话更可以看出。选项D是根据我们学习语言的经验得出的推断,但文中并没有这层隐含之意。

    Washoe Learned American Sign Language

    1.An animal that influenced scientific thought has died.A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the American state of Washington.Washoe had become known in the scientific community arid around the world for her ability to use American sign language.She was said to be the first non-human to learn a human language.Her skills also led to debate about primates and their ability to understand language.
    2.Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in 1966.In 1969,the Gardners described Washoe's progress in a scientific report.The people who experimented with Washoe said she grew to understand about 250 words.For example,Washoe made signs to communicate when it was time to eat. She could request foods like apples and bananas.She also asked questions like,"Who is coming to play?"Once the news about Washoe spread,many language scientists began studies of their own into this new and exciting area of research.The whole direction of primate research changed.
    3. However,critics argued Washoe only learned to repeat sign language movements from watching her teachers.They said she had never developed true language skills.Even now there are some researchers who suggest that primates learn sign language only by memory,and perform the signs only for prizes.Yet Washoe's keepers disagree.Roger Fouts is a former student of the Gardners.He took Washoe to a research center in Ellensburg,Washington.There,Washoe taught sign language to three younger chimpanzees,which are still alive.
    4.Scientists like private researcher Jane Goodall believe Washoe provided new information about the mental workings of chimpanzees.Today,there are not as many scientists studying language skills with chimps.Part of the reason is that this kind of research takes a very long time.
    5.Debate continues about chimps' understanding of human communication.Yet,one thing is sure一Washoe changed popular ideas about the possibilities of animal intelligence.

    The experimenters thought Washoe was intelligent_________.
    A:if the Gardeners' argument was sound
    B:because she was cleverer than other chimps
    C:when she wanted to eat
    D:while she was at a research center in Ellensburg
    E:because she could use sign language to ask for fruits
    F: while Washoe was learning sign language

    答案:E
    解析:
    文章第一段主要讲述的是Washoe死亡这件事以及对Washoe概括性的介绍,因此答案应当选择选项C。
    第二段主要介绍了当年Washoe学习手语的进展情况及惊人的成果,因此选项B的概括最准确。
    第三段主要讲的是一些批评家对Washoe语言能力的质疑,以及Gardner 夫妇的学生对此的反驳,因此选项E“对大猩猩智慧的争论”最符合要求。
    第四段只有三句话,主要讲很少人继续从事这项研究的原因是耗时太久,因而选项A总结的最正确。
    文章第二段中间提到当Washoe想吃东西的时候就会做手势,因此选择C项。
    文章第三段其他研究者对Gardner夫妇的看法提出了质疑,认为Washoe 并不能真正掌握语言,只是凭借记忆学习手语。因此选项A是正确的。

    Washoe Learned American Sign Language
    An animal that influenced scientific thought has died. A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the A-merican state of Washington.Washoe, had become known in the scientific community and around the world for her ability to use American Sign Language.She was said to be the first non-human to learn a human language .Her skills also led to debate about primates and their ability to under-stand language.
    Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in 1966.In 1969,the Gardeners described Washoe's progress in a scientific report. The people who experimented with Washoe said she grew to understand about 250 words. For example,Washoe made signs to communicate when it was time to eat. She could request foods like apples and ba-nanas .She also asked questions like,“Who is coming to play?”Once the news about Washoe spread,many language scientists began studies of their own into this nev and exciting area of research .The whole direction of primate research changed.
    However,critics argued Washoe only learned to repeat sign language movements from watc-hing her teachers.They said she had never developed true language skills.Even now,there are some researchers who suggest that primates learn sign language only by memory,and perform the signs only for prizes. Yet Washoe's keepers disagree.Roger Fouts is a former student of the Gar-deners. He took Washoe to a research center in Ellensburg,Washington. There,Washoe taught sign language to three younger chimpanzees,which are still alive.
    Scientists like private researcher Jane Goodall believe Washoe provided new information a-bout the mental workings of chimpanzees. Today,there are not as many scientists studying lan-guage skills with chimps. Part of the reason is that this kind of research takes a very long time.
    Debate continues about chimps' understanding of human communication. Yet,one thing is sure-Washoe changed popular ideas about the possibilities of animal intelligence.

    We can draw a conclusion from the last paragraph that______.
    A: whether chimps can learn a human language remains unanswerable
    B: primate have the ability to speak a language
    C: animals cannot learn a human sign
    D: Washoe is as intelligent as humans

    答案:A
    解析:
    根据第二段的“…many language scientists began studies of their own into this new and exciting area of research. The whole direction of primate research changed.”可知,这个试验影响了对灵长目动物的研究。故本题选D。


    段落主旨题。仔细阅读本段发现,这是对Washoe学习手语进展的报道。故选A。


    根据第三段的“However,critics argued Washoe only learned to repeat sign language movements from watching her teachers.”可知,批评家们认为,Washoe只是重复老师教给她的手语,并没有发展真正的语言技能。故本题选B。


    由第一段的“She was said to be the first non-human to learn a human language.”可知, B正确。由第三段“There,Washoe taught sign language to three younger chimpanzees...”知,是Washoe教三个年轻黑程猩手语的,A错误;根据第一段第二句可知,Washoe出生于非洲,死于美国华盛顿,C错误;根据倒数第二段的“Today,there are not as many sci-entists studying language skills with chimps.”可知,D项错误。故本题选B。


    根据最后一段第一句可知,科学家们对于黑猩猩理解人类语言仍有争议,因此黑猩猩能否学习人类语言仍然没有答案。因此选A。

    The Bilingual Brain
    When Karl Kim immigrated to the United States from Korea as a teenager,he had a hard time learning English.Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language.As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York Their work led to an important discovery.They found evidence that children and adults don't use the same parts ofthe brain when they learn a second language.
    The researchers used an instrument called an MRI(magnetic resonance imaging)scanner to study the brains of two groups of bilingual people.One group consisted of those who had learned a second language as children.The other consisted of people who,like Kim,learned their second language later in lite.Peoplefrom both groups were placed inside the MRI scanner ,This allowed Kim and Hirsch to see which parts of thebrain were getting more blood and were more active.They asked people from both groups to think about whatthey had done the day before ,first in one language and then the other.They couldn't speak out loudbecause any movement would disrupt(干扰)the scanning.
    Kim and Hirsch looked specifically at two language centers in the brain-Broca' s area, which isbelieved to control speech production,and Wernicke's area,which is thought to process meaning.Kim andHirsch found that both groups of people used the same part of Wernicke's area no matter what language theywere speaking.But their use of Broca's area was different.
    People who learned a second language as children used the same region in Broca's area for both tneir first and second languages.People who learned a second language later in life used a different part of Broca's area for their second language.How does Hirsch explain this difference?Hirsch believes that when language is first being programmed in young children,their brains may mix the sounds and structures of all languages in the same area.Once that programming is complete,the processing of a new language must be taken over by adifferent part of the brain.
    A second possibility is simply that we may acquire languages differently as children than we do asadults.Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.And that is very different from learning a language in a high school or college class.

    Which aspect of the two language centers in the brain does Paragraph 3 discuss?
    A:Impact.
    B:Function.
    C:Location.
    D:Size.

    答案:B
    解析:
    由文章第一段最后一句可知,他们发现证据表明儿童和成人在学习第二语言时使用的是大脑的不同区域,故选B。
    由文章第二段第一句可知,研究人员使用一种名为MRI扫描仪的设备来研究这两组学习双语人群的大脑活动,故选C。
    由文章第三段第一句可知,这两个中枢的作用分别是控制语言产出和处理语言意义,这属于中枢的功能,故选B。
    由文章第四段第一句可知,从儿童时期就开始学习第二语言的人在学习第二语言时所使用的大脑布洛卡区域和学母语时相同,故选A。
    文章最后一段主要讲的是儿童和成年人学习语言的方式和手段不同,尤其提到了母亲在教授儿童语言时的独特方式:触觉、视觉和听觉等多种手段并用。这与以后学校的语言学习手段有着很大不同。我们可以推断出母亲很擅长教授孩子语言,尤其从“Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.”这句话更可以看出。选项D是根据我们学习语言的经验得出的推断,但文中并没有这层隐含之意。

  • 第14题:

    When we discuss the English language,we illuminate our weaknesses,prejudices and ambitions.Language creates communities,and some of these are solidarities of complainers and pedants.A statement about proper English is a statement not only about the language,but also about people-about who the proper English are,or just about who the proper users of English are.Typically,the celebrants and defenders of proper English are celebrating or defending something other than language.Where does our sense of the sproper'come from?In arguing about what is right and what wrong in any language,we appeal to authority.This authority is embodied in academies,the Ministry of Education(or its equivalent)and universities,as well as in the pronouncements of people who have appointed themselves authorities and have become known as such.We commonly accept these judges'pronouncements.There are also geographical criteria.These are evident in statements such as'Natives of Perugia speak the best Italian'or'People in Alsace have funny accents'.Typically,we feel that there are certain environments in which our language is decently used,and we favour the usage that obtains there.(48)Sometimes,too,we defer to the example of a significant literary figure,saying that so-and-so is a model of correctness.A broader view is that'correct English is that which is used by the best writers',but who are they,and what are the criteria for their being so esteemed?The definition tends to be circular:the best writers are the ones who best use the resources of English.When we appeal to aesthetics,our arguments become vague.The aesthetically sensitive arbiter will argue that whatever is beautiful in language is good.(49)The problem here would seem to be that the desire for beautiful language concentrates on language as an object-on the sensory pleasure it affords rather than on what it signifies.Besides,as we know from our observation of others,the constant pursuit of beauty can be embarrassing.Alternatively,we may claim that the most elegant usage is that of the social elite.Perhaps this now seems an absurd position,but not long ago it would have been perfectly normal.The democratic option is to say that all doubtful matters should be decided by ballot,or just to say that the majority is right.We also appeal to logic.(50)Although there are discrepancies between logic and the ways we use language,we frequently use arguments from logic(or from what we imagine to be logic)in order to justify our choice of words or find fault with others'choices.In practice we tend to find our usual practices logical and anything else illogical.'Logic'is often a mask for arrogance and extreme patriotism.

    Washoe Learned American Sign Language

    1.An animal that influenced scientific thought has died.A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the American state of Washington.Washoe had become known in the scientific community arid around the world for her ability to use American sign language.She was said to be the first non-human to learn a human language.Her skills also led to debate about primates and their ability to understand language.
    2.Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in 1966.In 1969,the Gardners described Washoe's progress in a scientific report.The people who experimented with Washoe said she grew to understand about 250 words.For example,Washoe made signs to communicate when it was time to eat. She could request foods like apples and bananas.She also asked questions like,"Who is coming to play?"Once the news about Washoe spread,many language scientists began studies of their own into this new and exciting area of research.The whole direction of primate research changed.
    3. However,critics argued Washoe only learned to repeat sign language movements from watching her teachers.They said she had never developed true language skills.Even now there are some researchers who suggest that primates learn sign language only by memory,and perform the signs only for prizes.Yet Washoe's keepers disagree.Roger Fouts is a former student of the Gardners.He took Washoe to a research center in Ellensburg,Washington.There,Washoe taught sign language to three younger chimpanzees,which are still alive.
    4.Scientists like private researcher Jane Goodall believe Washoe provided new information about the mental workings of chimpanzees.Today,there are not as many scientists studying language skills with chimps.Part of the reason is that this kind of research takes a very long time.
    5.Debate continues about chimps' understanding of human communication.Yet,one thing is sure一Washoe changed popular ideas about the possibilities of animal intelligence.

    Washoe taught three younger chimps sign language_______.
    A:if the Gardeners' argument was sound
    B:because she was cleverer than other chimps
    C:when she wanted to eat
    D:while she was at a research center in Ellensburg
    E:because she could use sign language to ask for fruits
    F: while Washoe was learning sign language

    答案:D
    解析:
    文章第一段主要讲述的是Washoe死亡这件事以及对Washoe概括性的介绍,因此答案应当选择选项C。
    第二段主要介绍了当年Washoe学习手语的进展情况及惊人的成果,因此选项B的概括最准确。
    第三段主要讲的是一些批评家对Washoe语言能力的质疑,以及Gardner 夫妇的学生对此的反驳,因此选项E“对大猩猩智慧的争论”最符合要求。
    第四段只有三句话,主要讲很少人继续从事这项研究的原因是耗时太久,因而选项A总结的最正确。
    文章第二段中间提到当Washoe想吃东西的时候就会做手势,因此选择C项。
    文章第三段其他研究者对Gardner夫妇的看法提出了质疑,认为Washoe 并不能真正掌握语言,只是凭借记忆学习手语。因此选项A是正确的。
    第三段提到Washoe被带到了Ellensburg,在那里它甚至教会了其他三只黑猩猩手语,因此选项D是正确的。
    文章第一段和第二段告诉我们Washoe掌握了大量的词汇并能用手语同人交流,它是第一个能了解人类语言的非人类,因此人们自然会认为它很聪明。选项E是正确的。

    答案:F
    解析:
    空格后的“found”与选项F中的“discovery”的意义相近,且空格后的句子是对F的进一步解释。
    空格前一句表明要对两组使用双语的人员的大脑进行研究,空格后的句子“The other…”讲的是一组人员的情况。由此可推测出,空格处讲的应是另一组人员的情况,B项符合题意。
    整段讲的是Kim和Hirsch对大脑的两个语言中心的分析,空格前讲的是他们对Wernicke's area的使用情况的研究发现,空格处应为被测试者使用Broca's area的情况。A项符合题意。
    空格前两句表明了成人学习第二语言与儿童学习第二语言时对Broca's area的不同使用情况,后面的“Hirsch beheves…”是Hirsch对这一现象的解释,根据上下文语境可知,空格处应选择C项。

    Washoe Learned American Sign Language
    An animal that influenced scientific thought has died. A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the A-merican state of Washington.Washoe, had become known in the scientific community and around the world for her ability to use American Sign Language.She was said to be the first non-human to learn a human language .Her skills also led to debate about primates and their ability to under-stand language.
    Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in 1966.In 1969,the Gardeners described Washoe's progress in a scientific report. The people who experimented with Washoe said she grew to understand about 250 words. For example,Washoe made signs to communicate when it was time to eat. She could request foods like apples and ba-nanas .She also asked questions like,“Who is coming to play?”Once the news about Washoe spread,many language scientists began studies of their own into this nev and exciting area of research .The whole direction of primate research changed.
    However,critics argued Washoe only learned to repeat sign language movements from watc-hing her teachers.They said she had never developed true language skills.Even now,there are some researchers who suggest that primates learn sign language only by memory,and perform the signs only for prizes. Yet Washoe's keepers disagree.Roger Fouts is a former student of the Gar-deners. He took Washoe to a research center in Ellensburg,Washington. There,Washoe taught sign language to three younger chimpanzees,which are still alive.
    Scientists like private researcher Jane Goodall believe Washoe provided new information a-bout the mental workings of chimpanzees. Today,there are not as many scientists studying lan-guage skills with chimps. Part of the reason is that this kind of research takes a very long time.
    Debate continues about chimps' understanding of human communication. Yet,one thing is sure-Washoe changed popular ideas about the possibilities of animal intelligence.

    According to the passage,which of the following is true?
    A: Roger Fouts taught sign language to three younger chimpanzees.
    B: Washoe was the first chimp to use American Sign Language.
    C: A chimpanzee died of natural causes in Africa at a research center.
    D: Nowadays there are still lots of scientists experimenting with chimpanzees.

    答案:B
    解析:
    根据第二段的“…many language scientists began studies of their own into this new and exciting area of research. The whole direction of primate research changed.”可知,这个试验影响了对灵长目动物的研究。故本题选D。


    段落主旨题。仔细阅读本段发现,这是对Washoe学习手语进展的报道。故选A。


    根据第三段的“However,critics argued Washoe only learned to repeat sign language movements from watching her teachers.”可知,批评家们认为,Washoe只是重复老师教给她的手语,并没有发展真正的语言技能。故本题选B。


    由第一段的“She was said to be the first non-human to learn a human language.”可知, B正确。由第三段“There,Washoe taught sign language to three younger chimpanzees...”知,是Washoe教三个年轻黑程猩手语的,A错误;根据第一段第二句可知,Washoe出生于非洲,死于美国华盛顿,C错误;根据倒数第二段的“Today,there are not as many sci-entists studying language skills with chimps.”可知,D项错误。故本题选B。


    根据最后一段第一句可知,科学家们对于黑猩猩理解人类语言仍有争议,因此黑猩猩能否学习人类语言仍然没有答案。因此选A。
