    4、shop, a mortuary (太平间), a bank and a barber shop. It is filled with bits of St. Michaels“ commercial history, ranging from carpentry tools to an intricately decorated shoeshine stand and including a body board for carrying a corpse (尸体). “At one time, there were five funeral homes in St. Michaels,“

    5、Kate Fones, who is in charge of the Museum, pointed out. Teetotum is connected to the Sewell House, the first building of the museum, which was moved to the museum site in 1964. The building focuses on the home life during the 19th century, including period furniture and home artifacts of a local na

    6、ture, ranging from an intricate apple peeler and heavy clothes irons that had to be heated over a fire to a chamber pot (夜壶). The Sewell House also has its own history, being half of a building that was cut in two to provide two homes. The Sewell family added a kitchen and a loft to the two-story ha

The museum also tries to fell the 19th century history of African Americans in the town. The most recently added of the three buildings that make up the museum is the Chaney House

    8、, a two-story, two-room house that was owned by three free African Americans after it was built around 1850. The museum staff tries to appeal to year-round residents as well as summer people and other tourists. Having a steady supply of new exhibits, two per year, is a way to do that.(分数:71.00)(1).W

    12、总题数:1,分数:71.00)During the Second World War, doctors tried to save severely burned pilots with grafts of donated skin. The grafted skin looked good for a few days, but then withered and died. Studies led by Peter Medawarwho won a 1960 Nobel Prize for his workfound that grafts of an individual“s own s

    13、kin did work, while those of a donor did not. We now know that the donor skin grafts failed because the recipient“s immune system recognized the grafted skin as foreign and killed it. The same process leads to the rejection of donated organs. But how does our immune system learn what is self and wha

    14、t is foreign? As immunologist Daniel Davis explains in The Compatibility Gene , it is all down to specific genesformally known as the major histocompatibility complex genes. Although our appearance, lifestyle and career path may make us feel unique, we are actually always one of a group: it is only

    15、our compatibility genes that define us as true individuals. Davis provides a well-written and easy-to-read account of the sometimes complicated biology behind the crucial genes that affect our lives so profoundly. From early on in the evolution of life, individual cellsand later multicellular organi

Davis recounts how, when we are growing as fetuses, our compatibility genes train the immune system to recognize our own cells and tissues as “self“ and so, in healthy people, they know what not to a

    17、ttack. Our cells are identified by the presence of unique surface molecules, coded for by the compatibility genes. Meanwhile, our immune systems make antibodies. These are randomly generated in a kind of lottery, which means they will be able to attack a great diversity of molecules, especially thos

    18、e of pathogens. By chance, though, a few of these antibodies will also match the compatibility-gene molecules on our own cells. Leaving such antibodies around would be suicideliterally. To stop this, Darwinian-style selection comes into play within the immune system, eliminating any cells that produ

    19、ce antibodies matching “self“.(分数:71.00)(1).Why did the grafted skin withere and die after a few days?(分数:14.20)A.Because a person“s immune system identifies the grafted skin which comes from other people.B.Because people have different immune systems, and these immune systems can not be blended tog

    20、ether.C.Because the special features of grafted skin can not be adapted by the recipients.D.Because the recipients do not have powerful immune system for fighting diseases.(2).Why does the author say “Although our appearance, lifestyle and career path may make us feel unique, we are actually always

    21、one of a group“?(分数:14.20)A.People may have same appearance, lifestyle or career path, which can not be the unique feature.B.Our appearance, lifestyle and career path can help us distinguish ourselves from a group.C.People may have different appearance, lifestyle or career path, but they still can n

    22、ot be true individuals.D.Our appearance, lifestyle and career path define us to be a member of a group.(3).Which of the following does not help people develop the ability to recognize that which is different from them?(分数:14.20)A.Multicellular organisms.B.Individual cells.C.Compatibility genes.D.Sur

    26、 Translation(总题数:1,分数:20.00)2.香港是坐落于中国南端的一个弹丸小岛,150 多年前,还被形容为“ 荒芜之地 ”(barren rock)。优越的战略位置、 通讯条件 (communications)和商业文化,促进了香港经济和社会迅速发展。如今,香港已发展成为一个国际金融商贸中心,并与近 200 个国家和地区的公司有商业往来。在日趋全球化的经济中,香港正扮演着一个非常重要的角色。我们相信,香港的未来会更加光明灿烂。 (分数:20.00)_大学英语四级分类模拟题 526 答案解析(总分:192.00,做题时间:90 分钟)一、Part Writing(总题数:1,分数

You should start your essay with a brief description of the picture and then express your views on the topic that positive attitudes are essential to success. You should write at least 120 words but no more than 1

    28、80 words. (分数:30.00)_正确答案:()解析:Positive Attitudes Are Essential to SuccessIn the picture, a person is asking for guidance. What the counselor tells him is that though aptitude matters, attitude is even more important. I quite agree with her. The great inventor Edison made thousands of inventions in

    29、his life. However, he didn“t make them because he is extraordinarily smart. It was because he didn“t give up. When he failed, he tried another solution. He kept failing and trying, and finally he succeeded. Nobody is perfect. We all meet problems in our life, and we fail one time or another. It is o

    30、ur attitude that determines how we deal with the failure. A negative person may think it“s too difficult and give up. In doing so, he loses the possibility to succeed. A positive person, on the other hand, will learn from the experience, and think about how to do it better. If he keeps trying, he wi

    31、ll succeed. That is the power of a positive attitude.二、Part Reading Compr(总题数:0,分数:0.00)四、Passage One(总题数:1,分数:71.00)“History is so immediate here,“ said Marie Martin, incoming president of the St. Michaels Museum“s board of directors. “Let“s face itSt. Michaels is a museum.
