单选题The Adjustment in Understanding of Man"s Relation to the Physical Universe Nowadays the scattering of galaxies and the astounding abundance of stars are forcing those who ponder such matters to a further adjustment of their concept of the place and function of man in the material universe. In the history of the 1 human mind, with its increasing knowledge of the surrounding context, there must have been a time when the philosophers of the 2 tribes began to realize that the world was not simply centered on man himself. The geocentric concept, which accepted a universe centered on the earth, then became common 3 . The second adjustment in the understanding of man"s relation to the physical universe was not generally acceptable 4 the sixteenth century. Copernican revolution soundly 5 the heliocentric concept the theory of a universe 6 on the sun. Man is a stubborn adherent to official dogma; eventually, however, he accepted the sun as the center. Then, forty years ago, came the need for a third adjustment. This 7 has deeply exploded man"s pride and 8 , for it has carried with it the knowledge of the appalling number of galaxies. The galactocentric universe 9 puts the earth and its life near the edge of one great galaxy in a universe of millions of galaxies. Man becomes peripheral among the billions of stars of his own Milky Way; and, according to the revelations of paleontology and geochemistry, he is 10 and apparently transient in the 11 of cosmic time. The downgrading of the earth and sun and the elevation of the galaxies is not the end of this 12 of scientific pilgrims through philosophic fields. The need for another 13 adjustment now 14 not wholly unexpected by scientists, 15 wholly the result of one or two scientific revelations. Our new problem concerns the spread of life throughout the universe. As unsolicited spokesmen for all the earthly organisms of land, sea and air, we ask the thrilling question: Are we alone?

单选题 American Sports The United States is a sports-loving nation. Sports in America take a variety of forms. organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is found; and hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year. Some sports are called spectator sports, as the number of spectators greatly exceeds the number playing in the game. Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall. Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game of cricket. Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It is still played by almost every college and university in the country, and the football stadiums of some o~ the largest universities seat as many as 80,000 people. The game is not the same as European football or soccer. In American football there are 11 players on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. Basketball is the winter sport in American schools and colleges. Like football, basketball originated in the US and is not popular in other countries. Many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly. Other spectator sports include wrestling, boxing, and horse racing. Although horseracing fans call themselves sportsmen, the accuracy of the term is questionable, as only the jockeys who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do "not assemble” primarily to see the horses race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.

单选题The Titanic had sixteen lifeboats, and four collapsible boats which could carry just over half the number of people on board her maiden voyage and only a third of the Titanic's total capacity. Regulations for the number of lifeboats required were based on outdated British Board of Trade regulations written in 1894 for ships a quarter of the Titanic's size. and had never been revised. Under these requirements, the Titanic was only obliged to carry enough lifeboats to seat 962 people. At design meetings in 1910 ,the shipyard's managing director had proposed that forty eight lifeboats be installed on the Titanic, but the idea had been quickly rejected as too expensive. Discussion then turned to the ship's decor, and as the director later described the incident, "We spent two hours discussing carpet for the first Class cabin and fifteen minutes discussing lifeboats". What did the director mean by saying" We spent two hours discussing carpet for the first class cabin and fifteen minutes discussing lifeboats"?A. Carpet for the first class cabin was a very important issue in the design of Titanic.B. Not enough attention had been paid to safety in the designing of Titanic.C. The designers had no idea of the dangers Titanic would be exposed to.D. The designers were careful with the design of' Titani

单选题{{B}}第三篇{{/B}} "Salty" Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University's School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair has recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little slat and store what they do absorb in cells that do not affect the plants' growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.

单选题Men Too May Suffer from Domestic Violence Nearly three in 10 men have experienced violence at the hands of an intimate partner during their lifetimes according to one of the few studies to look 1 domestic violence and health among men. "Many men actually do experience domestic violence, although we don"t hear about it 2 ," Dr. Robert J. Reid of the University of Washington in Seattle, one of the study"s authors, told Reuters Health. "They often don"t tell 3 we don"t ask. We want to get the message out to men who 4 experience domestic violence that they are not alone and there are resources available to 5 ". The researchers asked study participants about physical abuse and non-physical 6 , such as threats that made them 7 for their safety, controlling behavior (for example, being told who they could associate with and where they could go) , and constant name-calling. Among men 18 to 54 years old, 14.2 percent said they had experienced intimate partner 8 in the past five years, while 6.1 percent reported domestic violence in the previous year. Rates were lower for men 55 and 9 , with 5.3 percent reporting violence in the past five years and 2.4 percent having experienced it in the past 12 months. Overall, 30.5 percent of men younger than 55 and 26.5 percent of older men said they had been victims of 10 violence at some point in their lives. About haft of the violence the men 11 was physical. However, the physical violence men reported wasn"t as 12 suffered by women in a previous study; 20 percent to 40 percent of the men rated it as severe, compared to 61 percent of 13 . Men who reported experiencing domestic violence had more emotional and mental health problems 14 those who had not, especially older men, the 15 found.

单选题The National Park Service America's national parks are like old friends. You may not seethem for years at a time, but just knowing they're out there makes you feelbetter. Hearing the names of these famous old friends-Yosemite, Yellowstone,Grand Canyon - revives memories ofvisits past and promotes dreams of those still to come. From Acadia to Zion, 369 national parks are part of a continuallyevolving system. Ancient fossil beds, Revolutionary War battlefields,magnificent mountain ranges, and monuments to heroic men and women who moldedthis country are all a part of our National Park System (NPS). The care and preservationfor future generations of these special places is entrusted to the NationalPark Service. Uniformed Rangers, the most visible representatives of theService, not only offer park visitors a friendly wave, a helpful answer, or athought-provoking history lesson, but also are skilled rescuers, firefighters,and dedicated resource protection professionals. The National Park Service ranksalso include architects, historians, archaeologists, biologists, and a host ofother experts who preserve and protect everything from George Washington'steeth to Thomas Edison's wax recordings. Modern society has brought the National Park Service both massivechalienges and enormous opportunities. Satellite and computer technologies areexpanding the educational possibilities of a national park beyond it's physicalboundaries. Cities struggling to revive their urban cores are turning to the ParkService for expert assistance to preserve their cultural heritage, createpocket parks and green spaces, and re-energize local economies. Growingcommunities thirsty for recreational outlets are also working with the NPS toturn abandoned railroad tracks into bike and biking trails, as well as giving unusedfederal property new life as recreation centers. To help meet these challenges and take advantage of theseopportunities, the National Park Service has formed partnerships - some datingback 100 years, some only months old -with other agencies, state and local governments, corporations, American Indiantribes and Alaska Natives, Park Friends groups, cooperating associations,private organizations, community groups and individuals who share the NationalPark ethic. National Park Week 1996 is a celebration of these partnerships.

单选题 Stone Hill Mall Stone Hill Mall has fewer large department stores than most malls but, instead, features more than 100 small specialty shops, while the few that are not used yet will be filled as soon as the mall's owners find proprietors (业主) who fit the mall's image. One thing that makes Stone Hill Mall popular was that all of the stores remain open from 9 am until 10 pm, Monday through Friday. This favourable start has certainly been advantageous. Thanks to such features as its being the only shopping centre in the area to provide free baby- sitting for children from two to eight years old and its offering restaurants to suit every pocket, with the possible exception of the highly budget-conscious. Furthermore, as far as movie entertainment is concerned, Stone Hill Mall tops Westgate Mall, which looked very impressive when it opened, with three separate cinemas. Besides, the air-conditioning system makes sure a comfortable inside temperature of 25 degrees centigrade no matter what the weather is like outside, and in addition to its three beautiful fountains, the mall has a quiet garden area with comfortable benches and chairs for shoppers who have become tired. One complaint about Stone Hill Mall is that it is located outside the city, but there is a regular bus service between the mall and the city centre. A further complaint might be that, although the mall is surrounded by trees to match it with the scenery, it will be some years before these can effectively make the main buildings and the vast parking lot a part of the area around.

单选题Dining Custom Every land has its own dining custom, and the United States is no exception. Americans feel that the first rule of being a polite guest is to be on time. If a person is invited to dinner at 6: 30, the hostess expects him to be there at 6:30 or not more than a few minutes after. Because she usually does her own cooking, she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come. If he is late, the food will not be so good, and the hostess will be disappointed. When the guest can not come on time, he calls his host or hostess on the telephone, gives the reason, and tells at what time he thinks he can come. As guests continue to arrive, the men in the group stand when a woman enters and remain standing until she found a chair. A man always rises when he is being introduced to a woman. A woman does not rise when she is being introduced either to a man or a woman unless the woman is much older. When the guests sit down at a dinner table, it is customary for the men to help the ladies by pushing their chairs under them. Even an American may be confused by the number of knives, forks, and spoons besides his plate when he sits down to a formal dinner. The rule is simple, however: use them in the order in which they lie, beginning from the outside. Or watch the hostess and do what she does. The small fork on the outside on the left is for salad, which is often served with the soup. The spoon on butter spreader, on a small bread-and-butter plate at the left. As the bread is passed, each quest puts his piece on the bread-and-butter plate.
