单选题Ants first captured the attention of software engineers in the early 1990s. A single ant cannot do much on its own, but a group of ants (51) can solve complex problems. That inspired people like Marco Dorigo, who is one of the founders of a (52) known as group intelligence. Ants are good at choosing the shortest possible route between a food (53) and their nest. This reminds us of a classic computational travelling-salesman problem. Given a list of cities and their (54) apart, the salesman must find the shortest route needed to visit each city once. As the number of cities (55) , the problem gets more complicated. Ants solve their own problem using chemical signals called pheromones (信息素), when an ant finds food, she takes it back to the nest, (56) a pheromone trail that will attract others. The more ants that (57) the trail, the stronger it becomes. (58) , the pheromones evaporate (挥发) quickly, so once all the food has been collected, the trail soon goes cold. This rapid evaporation means long trails are less (59) than short ones, all else being equal. Pheromones thus turn the (60) intelligence of the individual ants into something more powerful.

单选题It's 8:30, time for John to start work. So he turns on his radio. Then he eats breakfast. As he eats, he reads his e-mail and reviews his to-do list. Then he sits on the sofa and thinks about an article he needs to write... Wait a minute! Radio? Breakfast? Sofa? What kind of workplace is this? Well, actually it is John's house, and he is a telecommuter—he works at home, communicating with the workplace through the Internet. Like John, millions of people—and their employer—are finding that telecommuting is a great way to work. Telecommuters can follow their own schedules. They work in the comfort of their homes, where they can also look after young children or elderly parents. They save time and money by not traveling to work. Their employers save, too, because they need less office space and furniture. Studies show that telecommuters change jobs less often. This saves employers even more money. Telecommuting helps society, too, by reducing pollution and traffic problems. Jobs that are suited to telecommuting include writing, design work, computer programming and accounting(会计). If a job involves working with information, a telecommuter can probably do it.

单选题Human cloning technology could be used to reverse heart attacks. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged, and other problems may be solved if human cloning and its technology are not forbidden. With cloning, infertile couples could have children. Current treatments for infertility, in terms of percentages, are not very successfully. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before. We should be able to clone the bone marrow for children and adults suffering from leukemia．This is expected to be one of the first benefits to come from cloning technology. We may learn how to switch cells on and off through cloning and thus be able to cure cancer. Cloning technology can be used to test for and perhaps cure gene-related diseases. The above is just a few examples of what human cloning technology can do for mankind．This new technology promises unprecedented advancement in medicine if people will release their fears and let the benefits begin.

单选题{{B}}Text 3{{/B}} Some oil companies plan to get rid of some of the pollution they produce by pumping it into rocks deep inside the Earth, where they say it will stay for thousands of years. Other people, though, aren' t so sure this is advisable; environmental groups say that putting this pollution back into the Earth is a had idea. When oil burns, It doesn' t just produce heat: it also produces carbon dioxide. Carbon dioxide is a natural part of the air, but because people bum so much oil, there' s too much carbon dioxide in the air. This extra carbon dioxide is pollution; some scientific studies show that carbon dioxide is one of the" greenhouse gases" that is causing the Earth's temperature to rise. Environmentalists say that the oil companies' plans may not work. The oil companies say they are making sure that the gas will never escape, but environmentalists wonder how the oil companies can be so sure that the gas won' t seep into the air. They also point out that there' s no way to check to make sure the gas isn't leaking. In addition, the environmentalists point out that the pumping costs money—for research and for equipment--that the oil companies should be spending on preventing pollution, rather than on just moving it someplace else. Another problem ,say some people who are concerned about the Earth, is that if the oil companies find a cheap way to get rid of their pollution, they won' t look for new kinds of energy. These environmentalists say that energy companies should be researching ways to use hydrogen, wind power, and solar power instead of finding better ways to use oil. They argue that continuing to use oil means that we will still need to buy oil from other countries instead of producing our own cheap, clean energy. Environmentalists also say that burying pollution just pushes the problem into the future, rather than really solving it. They say that if the oil companies pump carbon dioxide into the rocks inside the Earth, it will be there for thousands of years, and that no one knows if this plan—even if it works--might turn into a pollution problem for all of us in the future. The oil companies insist that their plan is safe, and that putting the gas inside the Earth is a reasonable way to deal with it, They point out that there is a lot of room in the Earth for this extra gas, and that putting carbon dioxide inside the Earth means that the gas won' t be in the air, and if it' s not in the air, it won' t make the Earth warmer.
