1、MBA（英语）阅读理解练习试卷 17 及答案与解析一、Section III Reading ComprehensionDirections: Read the following four passages. Answer the questions below each passage by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.0 A We try our best to develop a vaccine. B The cause of the flu epidemics arising so often
2、in Asia. C The general introduction of “BIRD FLU“. D The reason of the new strain of flu arising. E The diseases caused by viruses threat human-beings. F The connections between bird and viruses are complex. 1. _ Human beings have known the diseases caused by viruses since thousands of years ago; an
3、d were fearful of them. The diseases are infectious hepatitis, polio, rabies, and AIDS. Now we can find easily that why the late Sir Peter Medawar, Nobel laureate in physiology or medicine, wrote “A virus is a piece of bad news wrapped in protein.“ Perhaps the most lethal virus in human history has
4、been the influenza virus. About 21 million Americans and Europeans died of flu within 18 months in 1918 and 1919. It was an astonishing number. The outbreak in Hong Kong in 2003 of a potentially deadly strain of flu has attracted the worlds attention once again on flu. Flu viruses we call are RNA an
5、imal viruses. An individual flu virus resembles a rod studded with spikes composed of two kinds of protein. There are three “types“ of flu virus, distinguished by their capsid protein, which is different for each type: Type A flu virus causes most of the serious flu epidemics in humans, and also occ
6、urs in mammals and birds. Type B and Type C viruses are only in to humans and rarely cause serious health problems. 2. _ The new strain of flu arises not by mutation, but recombination. Viral genes are readily reassorted by genetic recombination, sometimes putting together novel combinations of H an
7、d N spikes unrecognizable by human antibodies specific for the old configuration. Viral recombination of this kind seems to have been responsible for the three major flu pandemics (that is, world wide epidemics) that have occurred in this century, by producing drastic shifts in Hand N combinations.
8、The “Killer flu“ of 1918, A (HIN1), killed 21 million people. The Asian flu of 1957, A (H2N2), killed over 100,000 Americans. The Hong Kong flu of 1968, A (H3N2), infected 50 million people in the United States alone, of which 70,000 died. 3. _ It is proved that the new strains of flu usually start
9、to develop in the far east. The most common hosts for influenza virus are ducks, chickens, and pigs, which in Asia often live in close proximity to each other and to humans. Pigs are subject to infection by both bird and human strains of the virus, and individual animals are often simultaneously inf
10、ected with multiple strains. This creates conditions favoring genetic recombination between strains, producing new combinations of H and N subtypes. The Hong Kong flu, for example, arose from recombination between A (H3N8) from ducks and A (H2N2) from humans. The new strain of influenza, in this cas
11、e A (H3N2), then passed back to humans, creating an epidemic. 4. _ A potentially deadly new strain of flu virus, A (H5N1), has appeared in 2003, again in Hong Kong. Scientists paid great attention to this virus for two reasons. First, A (H5N1) represents a novel combination of H and N spikes, the so
12、rt of new combination that has in the past been associated with major flu epidemics. Second, unlike all previous instances of new flu strains, A (H5N1) passed to humans directly from birds, in this case chickens. Fortunately the bird flu virus does not appear to spread easily from person to person.
13、5. _ A vaccine directed against the bird flu virus has not been developed. Such a vaccine will not be easy to produce. Public health scientists have injected the duck virus into laboratory ferrets, often used as test animals in flue research because they develop classic respiratory symptoms. Is the
14、duck virus enough like bird flu that the ferrets develop antibodies that protect against A (H5N1)? The result will be known after months.5 A Healing power from the young. B A harmful practice out of human weakness. C Who should take the burden of looking after our old people? D A cure to loneliness
15、found in kids. E Comfort typical of a multigenerational family. F Benefit of extended age groups. Until late in 20th century, most Americans spent time with people of all generations. Now baby boomers may not have much contact with old people until theyre relatively old themselves. 1. _ Thats becaus
16、e we group people by age. We put our three-year-olds together in day-care centers, our 13-year-olds in schools and sports activities, and our 80-year-olds in senior-citizen homes. Why? We segregate the old for many reasons: prejudice, ignorance, a lack of good alternatives. Younger people sometimes
17、avoid the old to evade fears of aging and dying. Death is easier to bear in the abstract. Its much harder to watch someone we love fade before our eyes. Sometimes its so hard that we stay away from the people who need us the most. 2. _ But there are problems with this age-segregation experiment. Ten
18、 14-year-olds grouped together will form a Lord of the Flies culture-competitive and mean. But ten people ages two to 80 grouped together will fall into a natural age hierarchy that nurtures and teaches them all. For our own mental and social health, we need to reconnect the age groups. Fortunately,
19、 some of us have found our way to the old. And we have discovered that they often save the young. 3. _ A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and v
20、isit. Soon the children had many new friends, with whom they shared food, stories and projects. “My children have never been less lonely,“ the reporter said. 4. _ The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People
21、who hadnt gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed comatose woke up to watch the child. Babies have an amazing power to comfort and heal. 5. _ Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my hus
22、band put it, “My grandparents gave me a deep sense that things would turn out right in the end.“ Grandchildren speak of attention they dont get from harried parents. “My parents were always telling me to hurry up, and my grandparents told me to slow down,“ one friend said. A teacher told me she can
23、tell which kids have relationships with grandparents: they are quieter, calmer, more trusting.MBA（英语）阅读理解练习试卷 17 答案与解析一、Section III Reading ComprehensionDirections: Read the following four passages.
