单选题 Phyllis Wheatley is regarded as America's first black poet. She was born in Senegal, Africa, about 1753 and brought to America aboard a slave ship at about the age of seven. John and Susannah Wheatley bought her for three pounds at a slave auction in Boston in 1761 to be a personal servant of Mrs. Wheatley. The family had three other slaves, and all were treated with respect. Phyllis was soon accepted as one of the family, which included being raised and educated with the Wheatley's twin 15-year-old children, Mary and Nathaniel. At that time, most females, even from better families, could not read and write, but Mary was probably one of the best educated young women in Boston. Mary wanted to become a teacher, and in fact, it was Mary who decided to take charge of Phyllis's education. Phyllis soon displayed her remarkable talents. At the age of twelve she was reading the Greek and Latin classics and passages from the Bible. And eventually, Mrs. Wheatley decided Phyllis should become a Christian. At the age of thirteen Phyllis wrote her first poem. She became a Boston sensation after she wrote a poem on the death of the evangelical preacher George Whitfield in 1770. It became common practice in Boston to have "Mrs. Wheatley's Phyllis" read poetry in polite society. Mary married in 1771, and Phyllis later moved to the country because of poor health, as a teacher and caretaker to a farmer's three children. Mary had tried to interest publishers in Phyllis's poems but once they heard she was a Negro they weren't interested. Then in 1773 Phyllis went with Nathaniel, who was now a businessman, to London. It was thought that a sea voyage might improve her health. Thirty-nine of her poems were published in London as Poems on Various Subjects, Religious and Moral. It was the first book published by a black American. In 1775 Phyllis wrote a poem extolling the accomplishments of George Washington and sent it to him. He responded by praising her talents and inviting her to visit his headquarters. After both of her benefactors died in 1777, and Mary died in 1778, Phyllis was freed as a slave. She married in 1778, moved away from Boston, and had three children. But after the unhappy marriage, she moved back to Boston, and died in poverty at the age of thirty.

单选题An Underwater Hotel 水下旅馆 In a bay near Almeria in Southern Spain will be built the world's first underwater residence for tourists. The hotel will be 40 feet down in the Mediterranean. As all the world opened to tour operators, there was still a frontier behind which lay three quarters of the globe's surface, the sea; in whose cool depths light fades; no winds blow; there are no stars. There even the most bored travelers could recapture their sense of romance, terror or beauty. For a submerged hotel is such a beautiful idea． The hotel will cost? 170,000 and will be able to accommodate up to ten people a night. Up until now only scientists and professional divers have lived under the sea, but soon, for the first time, the public will be able to go down into the darkness. They will have to swim down in diving suits, but at 40 feet there would be no problem about decompression. Design of the hotel was crucial. Most of the underwater structures used before had been in the shape of a diving bell or submarine. Professional divers could cope with such things but ordinary people would run the risk of violent claustrophobiA．Then an Austrian architect had the idea of making three interconnecting circular structures, 18 feet in diameter, and looking much like flying saucers. They would be cast in concrete and launched from the shore. Towed into position they would then be sunk. A foundation of cast concrete would already be in place on the sea beD．Pylons would attach the structures to this. Once in position the structures would be pumped dry. The pylons, made to withstand an uplift pressure of 350 tons, would then take the strain. Cables linking the underwater structures to the hotel on shore would connect it with electricity, fresh water, television, and an air pump, and also dispose of sewage. Entry would be from underneath, up a ladder; because of the pressure inside there would be no need of airlocks or doors. The first structure would include a changing room and a shower area, where the divers would get out of their gear. There would also be a kitchen and a lavatory. The second structure would contain a dining room/lecture theater, and sleeping accommodation for eight people. The third structure would contain two suites. A steward would come down with the ten customers, to cook and look after them. Television monitors would relay all that went on to the shore so that discussions on the sea bed could be transmitted to all the world． Around the hotel there are plans to build a strange secret garden, over 100 yards square, of plastic shapes, curves, circles, hollows. This would have a dual function. First, to attract fish who would see it as a shelter and hiding place; secondly, to allow guests looking out of the reinforced windows to see a teeming underwater life. So far at the site a diving tower 33 feet deep has been installed for diving instruction. An aquarium has been built, and zoologists from Vienna University are in regular attendance to supervise its stocking. There are storage cupboards full of the plastic shapes for the underwater garden and there is a model of the hotel. All that is needed now is permission from the Spanish Government to start building.

单选题 Are we "Math People" or "English People"? The earliest hint of verbal dexterity is enough to earn a language ability label while the slightest struggle with a mathematical concept might as well come with a forehead stamped "{{U}}mathematically inept{{/U}}." "The common wisdom in the United States is that mathematical ability is somehow innate, and there are people who, no matter how hard they try, will not be able to achieve in mathematics," said A1 Cuoco, director of the Center for Mathematics Education at Educational Department Center Inc, a nonprofit in Newton, who has taught math since the late 1960s. Struggling in math is socially acceptable, while having trouble reading is reason for worry. Why the stigma around numbers? Cuoco said the belief that you've got a math gene is "an American phenomenon." In the United States, he said, "kids from a very young age are put into two categories: those who get {{U}}it{{/U}} and those who don't. In other countries, the {{U}}perspective{{/U}} is that if you work hard and apply yourself, anyone can achieve mathematics at an advanced high school level." Abby Coyle, 15, of Newton, a sophomore at Dana Hall School, an all-girls campus in Wellesley, has long noticed educators putting math and English at opposite poles. "It seems there is always a distinct classification between math and science and English and social studies," said Coyle. Part of making your way through elementary school, she said, is figuring out if you're better at math or English. "Once you fit into one, you don't concentrate on the other side," said Coyle, who said it has taken effort to see herself as good at both. The cultural divide around math is not just about sorting students into math-focused and English-focused, but to make assumptions based on gender. Are boys better at math? Do girls soar in English? These may be common presumptions, but research suggests.

单选题 In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenza-like cases. Influenza is sometimes called "flu" or a "bad cold". He took samples from the throats of patients in his hospital and was able to find the virus of this influenza. There are three main types of the influenza virus. The most important of these are type A and B, each of them having several subgroups. With the instruments at the hospital, the doctor recognized that the outbreak was due to a virus in group A, but he did not know the subgroup. Then he reported the outbreak to the World Health Organization in Geneva. WHO published the important news alongside reports of a similar outbreak in Hong Kong, where about 15-20 percent of the population had become ill. As soon as the London doctors received the package of throat samples, doctors began the standard tests. They found that by reproducing itself with very high speed, the virus had grown more than a million times within two days. Continuing their careful tests, the doctors checked the effect of drugs against all the known subgroups of virus type A. None of them have any protection. This, then, was something new, a new influenza virus, against which the people of the world had no help whatever. Having found the virus they were working with, the two doctors now dropped it into the noses of some specially selected animals, which get influenza much as human beings do. In a short time the usual signs of the disease appeared. These experiments proved that the new virus was easy to catch, but that it was not a killer. Scientists, like the general public, call it simply Asian flu. The first discovery of the virus, however, was made in China before the disease had appeared in other countries. Various reports showed that the influenza outbreak started in China, probably in February 1957. By the middle March it had spread all over China. The virus was found by Chinese doctors early in March. But China is not a member of the WHO and therefore does not report outbreaks of disease to it. Not until two months later, when travelers carded the virus into Hong Kong, from where it spread to Singapore, did the news of the outbreak reach the rest of the world. By this time it was well on its way around the world.

单选题Are you interested in seeing the beautiful fall foliage of New England but tired of traffic jams and overbooked hotels? Then this year forget the crowds in New England and see the beautiful colors of autumn in the Catskills. These rugged mountains in New York State, just 90 miles northwest of New York City, are famous for the legendary tales of Rip Van Winkle, and more recently for the summer hotels mat sprang up in the region during the 1940s, 1950s, and 1960s. Families trying to escape the heat of New York City found the Catskills to be the perfect place to stay for a month or so each summer. By the late 1950s there were over 500 resorts and hotels offering nighttime entertainment as well as all kinds of outdoor activities. Famous comedies like Jackie Gleason, Joan Rivers, and Sid Caesar all got their start touring the hotel clubs here. Since the introduction of air-conditioning and cheaper air travel, however, families have stopped coming to the Catskills in such large numbers, chasing instead more distant locations at different times of the year. Many of the Catskills hotels closed in the 1970s, but some remain and have expanded and changed their facilities to meet the needs of today's visitors. Currently, there are many activities available to the traveler besides witnessing the changing colors of the leaves. There is an all-organic sheep farm where visitors can see how a traditional sheep farm operates. There are also hundreds of miles of scenic drives in the area. Route 42, for instance, is an excellent site for spotting bald eagles. For more information on vacations in the Catskills, call the office of Public Information.

Most of us are doing the best we can to find whatever the right balance is...For me, that balance is family, work, and service. " Hillary Diane Rodham, Dorothy and Hugh Rodham's first child, was born on October 26, 1947.Two brothers, Hugh and Tony, soon followeD．Hillary's childhood in Park Ridge, Illinois, was happy and disciplined.She loved sports and her church, and was a member of the National Honor Society, and a student leader. Her parents encouraged her to study hard and to pursue any career that interested her. As an undergraduate at Wellesley College, Hillary mixed academic excellence with school government. Speaking at graduation, she said, "The challenge now is to practice politics as the art of making what appears to be impossible, possible. " In 1969, Hillary entered Yale Law School, where she served on the Board of Editors of Yale Law Review and Social Action, interned with children's advocate Marian Wright Edelman, and met Bill Clinton. The President often recalls how they met in the library when she strode up to him and said, "If you're going to keep staring at me, I might as well introduce myself.
