单选题请根据下面的短文回答第66-70题 American doctors say that mothers who smoke before their babies are born may slow the growth of their babies' lungs. They say reduced lung growth could cause the babies to have breathing problems and lung illness later in life. Doctors in Boston, Massachusetts studied 1,000 children. The mothers of some of the children smoked, the other mothers did not. Doctors found that the lungs of the children whose mother smoked were 8% less developed than the children whose mothers did not smoke, and that the children whose mothers smoked developed 20% more cold and breathing illness than other children later in life. Another recent study found that children had a greater chance of developing lung cancer if their mothers smoked. The study also showed that the danger of lung cancer increased only for sons and not for daughters, and that the father's smoking did not affect a child's chance of developing lung cancer.

单选题There was a time when parents who wanted an educational present for their children would buy a typewriter, a globe or an encyclopedia set. Now those 1 seem hopelessly old-fashioned, this Christmas, there were a lot of 2 computers under the tree. 3 that computers are their key to success, parents are also frantically insisting that children 4 taught to use them on school as early as possible. The problem for schools is that when it 5 computers, parents don"t always know best. Many schools are 6 parental impatience and are purchasing hardware without 7 educational planning so they can say, "OK, we"ve moved into the computer age. " Teachers 8 themselves caught in the middle of the problem—between parent pressure and 9 educational decisions. Educators do not even agree 10 how computers should be used. A lot of money is going for computerized educational materials 11 research has shown can be taught 12 with pencil and paper. Even those who believe that all children should 13 to computers warn of potential 14 to the very young. The temptation remains strong largely because young children 15 so well to computers. First graders have been 16 willing to work for two hours on math skills. Some have an attention span of 20 minutes. 17 school, however, can afford to go into computing, and that creates 18 another problem: a division between the havens and have-notes. Very few parents ask 19 computer instructions in poor school districts, 20 there may be barely enough money to pay the teacher.

单选题It is said that the public and Congressional concern about deceptive packaging rumpus started because Senator Hart discovered that the boxes of cereals consumed by him, Mrs. Hart, and their children were becoming higher and narrower, with a decline of net weight from 12 to 10.5 ounces, without any reduction in price. There were still twelve biscuits, but they had been reduced in size. Later, the Senator rightly complained of a store-bought pie in a handsomely illustrated box that pictured, in a single slice, almost as many cherries as there were in the whole pie. The manufacturer who increases the unit price of his product by changing his package size to lower the quantity of delivered can, without undue hardship, put his product into boxes, bags, and tins that will contain even 8-ounce, one-pound, two-pound quantities of breakfast foods, cake mixes, etc. A- study of drugstore and supermarket shelves will convince any observer that all possible sizes and shapes of boxes, jars, bottles, and tins are in use at the same time and, as the package journals show, week by week, there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation. The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by endless changes of package sizes, materials, shapes, art works, and net weights that are used for improving a product's market position. When a packaging expert explained that he was able to multiply the price of hard sweets by 2.5, from 1 dollar to 2.50 dollars by changing to a fancy jar, or that he had made a 5-ounce bottle look as though it held 8 ounces, he was in effect telling the public that packaging can be a very expensive luxury. It evidently does come high. When an average family pays about 200 dollars a year for bottles, cans, boxes, jars and other containers, most of which can't be used any more but stuffing the garbage can.

单选题Which one is not the right of the Prime Minister?

单选题The telecity is a city whose life, direction, and functioning are largely shaped by telecommunications. In the twenty-first century, cities will be based more and more on an economy that is dependent on services and intellectual property. Telecommunications and information networks will define a city's architecture, shape, and character. Proximity in the telecity will be defined by the speed and bandwidth of networks as much as by geographical propinquity. In the age of the telecity, New York and Singapore may be closer than, say, New York and Arkadelphia, Arkansas. Telecities will supersede megacities for several reasons, including the drive toward clean air, reducing pollution, energy conservation, more jobs based on services, and coping with the high cost of urban property. Now we must add the need to cope with terrorist threats in a high-technology world. Western mindsets were clearly jolted in the wake of the terrorist attack on the World Trade Center in New York City and attacks in Indonesia, Saudi Arabia, and elsewhere. But the risks posed by twentieth-century patterns of urbanization and architecture have yet to register fully with political figures and leaders of industry. The Pentagon, for example, has been rebuilt in situation rather than distributed to multiple locations and connected by secure landlines and broadband wireless systems. Likewise, the reconstruction of the World Trade Center complex still represents a massive concentration of humanity and infrastructure. This is a remarkably short-sighted and dangerous vision of the future. The security risks, economic expenses, and environmental hazards of over-centralization are everywhere, and they do not stop with skyscrapers and large governmental structures. There are risks also at seaports and airports, in food and water supplies, at nuclear power plants and hydro-electric turbines at major dams, in transportation systems, and in information and communications systems. This vulnerability applies not only to terrorist threats but also to human error, such as system-wide blackouts in North America in August 2003 and in Italy in September 2003, and natural disasters such as typhoons, hurricanes, floods, and earthquakes. Leaders and planners are only slowly becoming aware that over-centralized facilities are the most vulnerable to attack or catastrophic destruction. There is also growing awareness that new broadband electronic systems now allow governments and corporations to safeguard their key assets and people in new and innovative ways. So far, corporations have been quickest to adjust to these new realities, and some governments have begun to adjust as well.

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 dally. 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.

单选题As one of the biggest restaurants in the world, McDonald's origination and development has been a miracle in this field. The McDonald's story began in 1954 in San Bernardino, California. At first, the restaurant is run by two brothers, Dick and Mac McDonald. It didn't go very well at first; at one time it was nearly closed. However, the two brothers insisted on and overcame the difficulties, and made it turn for the better day by day. Ray Kroc, a milk shake machine salesman, saw the massive potential of the brothers' business and decided to get involved. He purchased the rights from the brothers, on April 15th, 1955. He became the McDonald brothers' first franchisee when he opened his own McDonald's restaurant in Des Plaines, a suburb just north of Chicago. The entry of Ray Kroc into the business contributed to the development in the history of McDonald's. He bought the rights to expand the McDonald's concept outside of California and Arizona, and quickly built the restaurant chain and by 1959 over 100 restaurants were in operation. What is the secret of Ray Kroc? As a matter of fact, the restaurant was a favor for many of the Iocal teens at first and the menu was primarily barbeque items. Eight years later, the restaurant was closed for several months as it was renovated to become a restaurant that served food and was easy to prepare and served quickly. The food was very limited including Hamburgers, French fries and cold drinks. The employees prided themselves on creating an assembly line type of food preparation and being speedy in getting their food to the customers. The very basic step paved the path to glory. It separated McDonald's from the rest of the competitors and attributes to their great success. The restaurant proved to be an instant success. By 1984, McDonald's served 17 million customers a day that was equivalent to serving lunch to the entire population of Australia and New Zealand. Today, McDonald's becomes one of the most famous and successful "fast food" chain in America and the world. McDonald's restaurants are now located in 31,000 locations all over the world, and the company employs more than 1.5 million people. Just have a look at its development in UK. In September 2004 the UK company owned restaurants employed 43,491 people: 40,699 hourly-paid restaurant employees, 2,292 restaurant managers, and 500 office staff. McDonald's franchisees employed a further 25,000 people.
