单选题Questions 21-25 are based on the following passage: It is curious how often sympathy for the old and infirm takes a form which actually humiliates them. Their friends, with good will, sometimes lean forward to rearrange their neckwear, touching their hair or patting their faces-things they would never presume to do, unasked, to one of their contemporaries. An equally humiliating habit is to talk about old people in front of them as if they were not there, discussing their health. It is now universally accepted that children should be encouraged to do as much as they can for themselves in order to develop their brains and muscles, but so few people today seem to have time to allow the elderly the same means of keeping their minds and muscles active. They perform innumerable services for the old that they would be much better left to do, even with a struggle, for themselves. Convenient flats, "motherly" visitors, or organized entertainments cannot make up for the fundamental need which must be satisfied--the need to retain to the end of life human dignity and the respect of one's fellows.

单选题Passage Four The remarkable progress of science and technology in the 20th century has brought enormous benefits to humankind. Long and healthy lives, economic prosperity and a pleasant and convenient living environment have resulted from technological progress based on advances in scientific knowledge. This progress will continue or may even accelerate in the future, because both the number of scientists and their activities are expanding throughout the world. We may expect, therefore, that science and technology will continue to contribute to the development of human society. At the same time, rapid scientific advances may raise some difficult problems. First of all, the disparity in scientific knowledge between those in scientific and technical professions and those in other areas will continuously expand. This may create a communications gap between the two groups that could affect obtaining public consent on important issues, such as the use of genetically engineered plants or human embryonic stem cells. Secondly, the 21st century will be characterized by a knowledge-based society and a knowledge of science will be required for many professions. Those who lack scientific knowledge will have fewer opportunities for good jobs. Thirdly, the enormous increase in scientific information will become a burden for children who must study science. Already young people seem to be losing interest in science, and this trend may increase in the future. Over the past several years, enrollment in high-school physics courses in Japan has been decreasing, which suggests that many young people are losing interest in physics or avoiding subjects that require diligent study. Finally, scientific research in the next century will require increasing levels of public investment because sophisticated research is usually expensive. If the public loses interest in science or does not understand the importance of research, it will become difficult for scientists to obtain sufficient financial support. Because of these considerations, I think that we need to carefully review present science education at different levels and to improve it in order to meet the expected rapid progress of science in the 21st century. At the level of primary education, the most important task is to stimulate children's interest in nature. Naive surprise at the wonders of nature will hopefully lead to a later interest in science. During their secondary education, students must learn logic and the principles of natural phenomena. They will gradually separate into groups of those who like and those who dislike science. It will be difficult to provide the latter students with the scientific basics that would be useful throughout their lives. This is also the case in university education. It is becoming a goal of general university education to give students who are not majoring in natural science and engineering some level of scientific literacy. In the future, all citizens, especially those expected to lead diverse areas of society should have a sound basis for understanding the progress of science. Because the pace of progress will accelerate further, continuing science education for the public is also of great importance.

单选题{{B}}Text 4{{/B}} Convenience food helps companies by creating growth; but what is its effect on people? For people who think cooking was the foundation of civilisation, the microwave is the last enemy. The communion(共享) of eating together is easily broken by a device that liberates household citizens from waiting for mealtimes. The first great revolution in the history of food is in danger of being undone, The companionship of the campfire, cooking pot and common table, which have helped to bond humans in collaborative living for at least 150, 000 years, could be destroyed. Meals have certainly suffered from the rise of convenience food. The only meals regularly taken together in Britain these days are at the weekend, among rich families struggling to retain something of the old symbol of togetherness. Indeed, the day's first meal has all but disappeared. In the 20th century the leisure British breakfast was undermined by the cornflake; in the 21st breakfast is vanishing altogether, a victim of the quick cup of coffee in Starbucks and the cereal bar. Convenience food has also made people forget how to cook. One of the apparent paradoxes of modern food is that, while the amount of time spent cooking meals has fallen from 60 minutes a day in 1980 to 13 minutes a day in 2002, the number of books and television programmes on cooking has multiplied. But perhaps this isn't a paradox. Maybe it is because people can't cook any more, so they need to be told how to do it. Or maybe it is because people buy books about hobbies—golf, yachting—not about chores. Cooking has ceased to be a chore and has become a hobby. Although everybody lives in the kitchen, its facilities are increasingly for display rather than for use. Mr. Silverstein's new book, Trading Up, looks at mid-range consumers' willingness to splash out. He says that industrial-style Viking cooktpos, with nearly twice the heat output of other ranges, have helped to push the "kitchen as theatre" trend in home goods. They cost from $1,000 to $9, 000．Some 75% of them are never used. Convenience also has an impact on the healthiness, or otherwise, of food. Of course, there is nothing bad about ready-to-eat food itself. You don't get much healthier than an apple, and all supermarkets sell a better-for-you range of ready-meals. But there is a limit to the number of apples people want to eat : and these days it is easier for people to eat the kind of food that makes them fat. The three Harvard economists in their paper Why have Americans become more obese? point out that, in the past, if people wanted to eat fatty hot food, they had to cook it. That took time and energy—a good chip needs frying twice, once to cook the potato and once to get it crispy (脆)—which discouraged consumption of that sort of food. Mass preparation of food took away that constraint. Nobody has to cut and double-cook their own fries these days. Who has the time?

单选题{{B}}Passage Two{{/B}} Hong Kong is a city inclined toward red; in Thailand the color is yellow; India leans toward reds and oranges. These are not political colors, but colors that suggest religious beliefs.To an Asian colors are full of beliefs, religious and otherwise. To the Chinese, red is very lucky, but to Thais yellow brings good fortune. The combination of blue, black, and white is, to the Chinese, suggestive of a funeral. Many Western businessmen believe that most Asians have become Westernized(西方化) in their outlook. This is true in part. But Westernization and education do not usually completely replace the culture and beliefs of an Asian's forefathers. They tend instead to make a more sophisticated combination of his culture and religious bonds. The approach required to sell an Asian any commodity must follow the basic formula of catering(迎合) to national pride, acknowledging equality, and understanding the Asian's beliefs. Color is a touchy thing. Advertisers are advised to take into consideration the religious and superstitious(迷信的) beliefs connected with colors before using them. The color combinations of green and purple are acceptable throughout Asia as these colors seem to have been worn by religious leaders in earlier times. However, using one or both of these colors is no guarantee of sales, as a prominent manufacturer of water-recreation products learned in Malaysia. Its home office received heated request from its distributors to stop shipments on all products colored green. The distributors reported that numerous customers associated the color green with the jungle and illness.
