    The Beginning of American Literature America has always been a land of beginnings.After Europeans"discovered"America in the fifteenth century,the mysterious New World became for many people a genuine hope of a new life,an escape from poverty and persecution,a chance to start again.We can say that,as a nation,America begins with that hope.When,however,does American literature begin?
    American literature begins with American experiences.Long before the first colonists arrived,before Christopher Columbus,before the Northmen who"found"America about the year 1000,native Americans lived here.Each tribe's literature was tightly woven into the fabric of daily life and reflected the unmistakably American experience of linking with the land.Another kind of experience,one filled with fear and excitement,found its expression in the reports that Columbus and other explorers sent home in Spain, French and English.In addition,the journals of the people who lived and died in the New England wilder- ness tell unforgettable tales of hard and sometimes heartbreaking experiences of those early years. Experience,then, is the key to early American literature.
    The New World provided a great variety of experiences,and these experiences demanded a wide variety of expressions by an even wider variety of early American writers.These writers included John Smith,who spent only two-and-a-half year on the American continent.
    They included Jonathan Edwards and William Byrd,who thought of themselves as British subjects,never suspecting a revolution that would create a United States of America with a literature of its own.American Indians,explorers,Puritan ministers,frontier wives,plantation owners-they are all the creators of the first American literature.

    What does"that hope"in the first paragraph refer to?
    A:The hope that America would be discovered.
    B:The hope to start a new life.
    C:The hope to see the mysteries of the New Worid.
    D:The hope to find poverty here.

    答案：B
    解析：
    由文章第一段第二句话“… a genuine hope of a new life …”可知，that hope指的是人们对在美洲新大陆开始新生活的希望。故选B。
    由文章第二段第二句可知，早在大约公元1000年北欧人发现美洲之前，美洲土著居民就居住在这里。第一句说“美国文学来源于美国人的生活经历”，由此可知，美国文学产生于公元1000年前就居住在这里的美洲土著居民的生活经历。故选D。
    由文章第二段第三句话“Each tribe ' s literature was tightly woven into the fabric of dail life and reflected the unmistakably American experience of linking with the land.”可知，美洲土部落的文学是他们日常生活的真实写照。故选A。
    文章最后一段的第一句话“Experience , then , is the key to early American literature."本段的主题句，说的是：美洲的生活经历是美国早期文学产生的关键因素。故选D。
    由文章最后一段第四句话“They included Jonathan Edwards and William Byrd , wh thought of themselves as British subjects,never suspecting a revolution that would create a United States of America with a literature of its own.”可知，这两位自认为是大英帝国臣民的英国作家对一场将会创造出一个拥有自己文学的美利坚合众国的革命从来没有任何怀疑。可见，一些英国作家对美国文学的将来充满信心。故选D。

    The First Settlement in North America
    It is very difficult to saythat when colonization began.The first hundred years after Christo-pher Columbus’s journey of discovery in 1492 did not produce any settlement on the North Ameri-can continent but rather some Spanish trading posts further south,a great interest in gold and ad-venture,and some colorful crimes in which the English had their part.John Cabot,originally from Genoa but a citizen of Venice, was estahlished as a trader in Bristol,England,when he made a journey in 1497 .But his ship,the Matthew,with its crew of eighteen,did no more than see an island(probably off the New England coast)and return home.He and his son made fur-ther voyages across the north Atlantic,which enahled the English Crown to claima“legal”title to North America.But for a long time afterwards the Europeans,interest in America was mainly con-fined to the Spanish activities further south.
    Th e fi rst heginning of permanent settlement in North America was nearly a hundred yearsa仁 ter Columbus'5 first voyage.The Englishman Sir Walter Raleigh claimed the whole of North Amer-ica for England,calling it Virginia.In 1585 he sent a small group ofpeople who landed in Roano-ke Island,but they stayed only for a year and then went back to England with another expedition, led hy Drake,in 1 5 87 .A second group who landed in 1 587 had all disappeared when a further expedition arrived in 1590.
    The first permanent settlement in North America was in 1 607 .English capitalists founded two Virginia companies,a southern one hased in London and a northern one based in Bristol.It was decided to give the name New England to the northernarea.The first settlers in Virginia were lit-tle more than wage slaves to the company.All were men and the experiment was not very success-ful .Many died.Those who survived lived in miserable conditions.By 1619 the colony had onlya thousand people.

    With John Cabot's arrival at an island off the New England coast in 1497,the British Crown claimed to be the legal owner of North America.
    A:Right
    B: Wrong
    C:Not mentioned

    答案：B

    文章的第一句话指出“很难说殖民地的开拓是从何时开始的”。


    第一段说在1492年哥伦布发现新大陆之后的100年中，北美大陆上没有出现过一块殖民者的定居地，但是在更往南的地方即南美出现了一些西班牙人的贸易站。


    第一段说John Cabot 1497年航行到了北美，之后他和他儿子又多次穿越北大西洋航行到北美，才使英国王室能够宣布对北美大陆的“合法”拥有权。


    1497年John Cabot首次乘坐“马修号”到达北美时船上有18位水手，再加上他本人船上应该至少有19人。


    第二段第一句话说北美大陆开始出现永久定居地是在哥伦布首航近一百年之后的事情，第三句话说Walter Raleigh爵士在1585年派了一小组人登上了Roanoke岛。


    第二段第二句话说英国人Walter Raleigh宣称整个北美都属于英国，并称之为弗吉尼亚。

    Where did Columbus first set foot on the New Continent?
    A

    Watling Island.

    B

    At the spot where a carved stone was erected to mark the event.

    C

    Somewhere in eastern Bahamas.

    D

    No consensus has been reached on the event among historians.


    正确答案： A
    解析：
    观点态度的找寻和判断。关于哥伦布于何时首次踏上新大陆，录音中首先指出历史学家Samuel Elliot Morrison已对此做出定论，但接着讲话者表示对于Morrison教授来说这个问题是解决了，“it was not for numerous other people on nautical history”，可知对于其他一些研究航海史的学者们来说，情况并非如此。由此可见，历史学家们并未就该事件达成一致意见。因此选项D为正确答案。
    【录音原文】
    The orthodox explanation of where Columbus first landed was carved in textbook stone more than 40 years ago by the dean of Columbus historians, Samuel Elliot Morrison. Morrison declared incontrovertible the evidence that Columbus first set foot on Watling Island in the eastern Bahamas. But if the question were closed for Professor Morrison, now dead, it was not for numerous other people on nautical history.

    Practice 1　　Born in 1451, the son of an Italian weaver, Christopher Columbus took to the sea at an early age, making up for his lack of formal education by teaching himself geography, navigation, and Latin. By the 1480s Columbus—a tall, red-haired, long-faced man with a ruddy complexion, oval eyes, and a prominent nose—was an experienced seaman. Dazzled by the prospect of Asian riches, he hatched a scheme to reach the Indies (India, China, the East Indies, or Japan) by sailing west. After the courts of Portugal, England, and France showed little interest in his plan, Columbus turned to Spain for backing. He won the support of Ferdinand and Isabella, the Spanish monarchs, and himself raised much of the money needed to finance the voyage. The legend that the queen had to hock the crown jewels is as spurious as the fable that Columbus set out to prove the earth was round.　　Columbus chartered one seventy-five-foot ship, the Santa María, and the Spanish city of Palos supplied two smaller caravels, the Pinta and Nina. From Palos this little squadron, with eighty-seven officers and men, set sail westward for what Columbus thought was Asia. The first leg of the journey went well, thanks to a strong trade wind. But then the breeze lagged, the days passed, and the crew began to grumble about their captain’s farfetched plan. To rally flagging morale, he reminded the crew of the dazzling riches awaiting them. Yet skepticism remained rife, and he finally promised that the expedition would turn back if land were not sighted in three days.　　Early on October 12, 1492, after thirty-three days at sea, a lookout on the Santa María yelled “Tierra! Tierra! [Land! Land!]” It was an island in the Bahamas that Columbus named San Salvador (Blessed Savior). According to Columbus’s own reckoning he was near the Indies, so he called the island people los Indios. He described the Indians as naked people, “very well made, of very handsome bodies and very good faces.” The Arawak Indians paddled out in dugout logs, which they called canoes, and offered gifts to the strangers. Their warm generosity and docile temperament led Columbus to write in his journal that “they invite you to share anything that they possess, and show as much love as if their hearts went with it.” Yet he added that “with fifty men they could all be subjugated and compelled to do anything one wishes.”

    1451年,克里斯托夫·哥伦布出生在一个意大利织工家庭。他从小就对航海着迷,自学了地理学、航海术和拉丁语,以此弥补没受过正规教育的缺憾。到了15世纪80年代,哥伦布已经是一位经验丰富的水手了,他身材高大,红头发,瘦长脸,面色红润,圆眼睛,高鼻梁。图片上美轮美奂的亚洲风光让哥伦布为之神往,于是他策划向西航行到印度群岛(包括印度、中国、东印度群岛或日本)。葡萄牙、英格兰和法国朝廷对此没有兴趣,于是哥伦布便转向西班牙求助,得到了国王斐迪南德和王后伊莎贝拉的支持。他自己还筹措了这次航海的很大一部分资金。传说王后抵押了自己王冠上的珠宝来资助他,纯属无稽之谈,这就和说哥伦布航海是为了证明地球是圆的一样荒谬。
    哥伦布自己租了一条75英尺长的船,船名叫“圣玛利亚”号,西班牙城市帕洛斯出了两条稍小的三桅帆船“平塔“号和”尼娜“号。这支75人的队伍就从帕洛斯起航了,朝着哥伦布心目中的亚洲向西进发。起初贸易风强劲,船队顺风顺水,十分顺利。但接着风就不那么帮忙了,日子一天天过去,水手们开始抱怨船长的计划异想天开。为了鼓舞士气,哥伦布向大家描绘了一番金银财宝任取任拿的灿烂前景。尽管如此,大家仍心存疑虑。最后,他承诺,如果三天后还见不到陆地,就打道回府。
    1492年10月12日一大早,在海上整整航行了33天之后,“圣玛利亚”号上的嘹望员突然放声大喊:“啊!陆地!”那是巴哈马群岛的一座岛屿,哥伦布把它命名为圣萨尔瓦多(意为“神圣的救世主”)。哥伦布自己估算,他差不多到了东印度群岛,所以管那儿的人叫印第安人。在他的描述中,印第安人浑身赤裸,“身体壮实,身材健美,长相标致”。阿拉瓦克印第安人划着挖空树干做成的独木舟,出来迎接,给这群陌生人献礼。他们慷慨热情,性情温顺,哥伦布在《航海日记》中写道,“他们倾其所有,邀君共享,一腔热忱,绝无保留。”他还写道,“只需50人便足以降伏他们,任我差遣。”

    According to Aleem Walji, the company’s first project is to _____.
    A

    set up a new system to warn people of infectious diseases

    B

    find out where infectious diseases develop

    C

    identify the causes of infectious diseases

    D

    cure patients of infectious diseases


    正确答案： A
    解析：
    细节辨认题。由原文第二段第二句“He said the company’s first project will help identify where infectious diseases are developing”可知，这笔资金的第一个项目是确定疾病的传染源出自哪里。B项是对这句话的同义替换。。A项偷换概念，文中第二段句末提到“Google. org will work with partners to strengthen early-warning systems”，谷歌将会与合作者一起努力加强早期预警机制，但并不是创建一个新的制度，故排除。C项对原文的理解错误，文中第二段提到要找到传染病的发源地，并没有说要找到疾病的发病原因。D项属于无中生有，文中没有提到。
