单选题Why does the author mention the Massachusetts Bay Colony?

单选题Susan Baroness Greenfield is a British institution. In a country that perceives its scientists as white-coated eccentrics, and probably male, Lady Greenfield is fashionable, extravagant, and female. At least, that is the image she has sought to project as a populariser of science. She is accused, though, of bringing another British institution, the Royal Institution (RI), to the verge of bankruptcy. The RI, of which she was director from 1998 until last Friday (January 8th), has made her job redundant. She says she plans to respond with a suit for sexual discrimination. Lady Greenfield, a neuroscientist at Oxford University, was recruited to shake up the two-century-old institution because she had made a name for herself, particularly on television, as one of the popular faces of science. The RI is, in part, a members" club famous for its Christmas lectures "adapted to a juvenile audience", which are broadcast on television every year, and its Friday evening discourses (black ties, please, gentlemen), in which prominent scientists chat about their work for precisely an hour—no more and no less—before everyone is served tea and chocolate cake. But it is also a serious research laboratory ( one of the longest-established in the world), looking into things like the medical applications of nanotechnology. Lady Greenfield"s offence, if offence it be, was to modernize the RI"s headquarters in Mayfair, one of the most stylish parts of London, without proper cost control. The redecoration included a high-class bar and restaurant that are open to the general public. Sadly, these opened for business in October 2008—the least favorable moment imaginable for such a venture. The redecoration, which cost ￡22m, much of which was raised by selling the institution"s shares of property, has left the RI ￡3m in debt, and the trustees have decided that one way to cut costs is to cut the job of director. Lady Greenfield, the first female director in a line that stretches back through Michael Faraday to Humphry Davy, seems to suspect that financial considerations were not the only ones when this decision was made. Instead of a director, the RI is to be led by a newly-invented chief executive officer, in the person of Chris Rofe. Mr. Rofe, who was appointed in April 2009, has a degree in business administration, not science. Given the debt, though, perhaps an alchemist, a person who devotes himself to turning ordinary metals into gold, would be the most appropriate person for the job.

单选题Read the following text. Answer the questions below the text by choosing A, B, C or D. A very important world problem is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate. So why is this huge increase in population taking place? It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather difficult. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind. If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50000 square meters. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the world's land cannot produce food. Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital"—its nonrenewable fossil fuels and other mineral deposits that took millions of years to form but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us. It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.

单选题The Death of a Spouse For much of the world, the death of Richard Nixon was the end of a complex public life. But researchers who study bereavement wondered if it didn' t also signify the end of a private grief. Had the former president merely run his allotted fourscore and one, or had he fallen victim to a pattern that seems to afflict longtime married couples: one spouse quickly following the other to the grave? Pat, Nixon's wife of 53 years, died last June after a long illness. No one knows for sure whether her death contributed to his. After all, he was elderly and had a history of serious heart disease. Researchers have long observed that the death of a spouse , particularly a wife, is sometimes followed by the untimely death of the grieving survivor. Historian Will Durant died 13 days after his wife and collaborator, Ariel; Buckminster Fuller and his wife died just 36 hours apart. Is this more than coincidence? "Part of the story, I suspect, is that we men are so used to ladies feeding us and taking care of us, " says Knud Helsing, an epidemiologist at the Johns Hopkins School of Public health, "that when we lose a wife we go to pieces. We don' t know how to take care of ourselves. " In one of several studies Helsing has conducted on bereavement, he found that widowed men had higher mortality rates than married men in every age group. But, he found that widowers who remarried enjoyed the same lower mortality rate as men who' d never been widowed. Women's health and resilience may also suffer after the loss of a spouse. In a 1987 study of widows, researchers from the University of California, Los Angeles, and UC, San Diego, found that they had a dramatic decline in levels of important immune - system cells that fight off disease. Earlier studies showed reduced immunity in widowers. For both men and women, the stress of losing a spouse can have a profound effect. "All sorts of potentially harmful medical problems can be worsened, "says Gerald Davison, professor of psychology at the University of Southern California. People with high blood pressure, for example, may see it rise. In Nixon's case, Davison speculates, "the stroke, although not caused directly by the stress, was probably hastened by it " Depression can affect the surviving spouse's will to live; suicide are elevated in the bereaved, along with accidents not involving cars. Involvement in life helps prolong it. Mortality, says Duke University psychiatrist Daniel Blazer, is higher in older people without a good social - support - system, who don' t feel they' re part of a group or a family, that they "fit in" somewhere. And that's a more common problem for men, who tend not to have as many close friendships as women. The sudden absence of routines can also be a health hazard, says Blazer. "A person who loses a spouse shows deterioration in normal habits like sleeping and eating. " he says. "They don't have that other person to orient them, like when do you go to bed, when do you wake up, when do you eat, when do you take your medication, when do you go out to take a walk? Your pattern is no longer locked into someone else's pattern, so it deteriorates. " While earlier studies suggested that the first six months to a year - or even the first week -- were times of higher mortality for the bereaved, some newer studies find no special vulnerability in this initial period. Most men and women, of course do not die as a result of the loss of a spouse. And there are ways to improve the odds. A strong sense of separate identity and lack of over - dependency during the marriage are helpful. Adult sons and daughters, siblings and friends need to pay special attention to a newly widowed parent. They can make sure that he or she is socializing, getting proper nutrition and medical care, expressing emotion and, above all, feeling needed and appreciated.

单选题The demoralizing environment, decrepit (老朽的) building and minimal materials make the high school experience for these children an uphill battle. Merely graduating from such a high school is difficult, much less becoming a high-caliber science or engineering student. Schools with students from a higher socioeconomic level would not tolerate the obstacles I encountered daily. Improvements need to be made efficiently and made soon, or the divisions among people in this country will only become more extreme. Of course, there are things that concerned citizens can do to help. Get involved with a school, especially one in a poor area. Volunteer to give a presentation or just to spend time with the children. My students were excited to talk to an insurance salesperson who came to give a career exploration lecture. They not only were genuinely interested in the opportunities he described but also were amazed that such a man would donate an afternoon to them. Although those measures can help, they are not enough. For teaching to be effective, the entire environment of the inner city needs to be changed. Teaching someone the difference between velocity and acceleration is irrelevant if the person is hungry and scared. Programs that educate parents in child-rearing, organize low-income groups into cooperative units, fight drug trafficking and help to clean up the ghettos physically will improve the life in the community. The small alterations and "new" proposals currently filling the newspapers are certainly not strong enough to transform a decaying and demoralized school structure that has been disintegrating for decades. Inner-city schools need so much more, and the children deserve so much more than our society is willing to give. Like many other people, I entered the teaching profession eager to investigate change and found many institutionalized obstacles in my way. It should not be so difficult to make a difference.
