单选题How men first learned to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their combinations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the number of words that mean something to us increases. Great writers are those who not only have great thoughts, but also express these thoughts in words which appeal powerfully to our minds and feelings. This charming and telling use of words is what we call literary (3~) style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and rude.

单选题In Plato's Utopia, there are three classes: the common people, the soldiers, and the guardians chosen by the legislator. The main problem, as Plato perceives, is to insure that the guardians shall carry out the purpose of the legislator. For this purpose the first thing he proposes is education. Education is divided into two parts, music and gymnastics. Each has a wider meaning than at present: "music" means everything that is in the province of the muses, and "gymnastics" means everything concerned with physical training fitness. "Music" is almost as wide as what is now called "culture", and "gymnastics" is somewhat wider than what "athletics" mean in the modern sense. Culture is to be devoted to making men gentlemen, in the sense which, largely owing to Plato is familiar in England. The Athens of his day was, in one respect, analogous to England in the nineteenth century: there was in each an aristocracy enjoying wealth and social prestige, but having no monopoly of political power; and in each the aristocracy had to secure as much power as it could by means of impressive behavior. In Plato's Utopia, however, the aristocracy rules unchecked. Gravity, decorum and courage seem to be the qualities mainly to be cultivated in education. There is to be a rigid censorship from very early years over the literature to which the young have access and the music they are allowed to hear. Mothers and nurses are to tell their children only authorized stories. Also, there is a censorship of music. The Lydian and Ionian harmonies are to be forbidden, the first because it expresses sorrow, the second because it is relaxed. Only the Dorian (for courage) and the Phrygian (for temperance) are to be allowed. Permissible rhythms must be simple, and such as are expressive of a courageous and harmonious life. As for gymnastics, the training of the body is to be very austere. No one is to eat fish, or meat cooked otherwise than roasted, and there must be no sauces or candies. People brought up on his regimen, he says, will have no need of doctors. Gymnastics applies to the training of mind as well. Up to a certain age, the young are to see no ugliness or vice. But at a suitable moment, they must be exposed to "enchantments", both in the shape of terrors that must not terrify, and of bad pleasures that must not seduce the will. Only after they have withstood these tests will they be judged fit to be guardians.

单选题Chinese farmers are earning ______ money per capita today as they did fifteen years ago. A. more than twice B. as twice C. twice more than D. more than twice as much

单选题 Maybe everyone has such an experience that you have to unwrap several layers of packaging when you enjoy a piece of candy. But this overuse of wrapping is not confined to luxuries. It is becoming increasingly difficult to buy anything that is not done up in beautiful wrapping. The package itself is of no interest to the shopper, who usually throws it away immediately. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment. Recycling is already happening with milk bottles which are returned to the dairies, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles. The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handy plastic packs. It is evident that more research is needed into the recovery and reuse of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.

单选题Why does cream go bad faster than butter? Some researchers think they find the answer, and it comes down to the structure of the food, not its chemical composition--a finding that could help rid some processed foods of chemical preservatives. Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions--tiny globules (小球) of one liquid evenly distributed throughout another. "The difference lies in what's in the globules and what's in the surrounding liquid", says Brocklehurst, who led the investigation. In cream, fatty globules drift about in a sea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. "This means that in cream, the bacteria are free to grow throughout the mixture", he says. When the situation is reversed, the bacteria are locked away in compartments (密封仓) buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients. They also slowly poison themselves with their waste products. "In butter, you get a self-limiting system which stops the bacteria growing", says Brocklehurst. The researchers are already working with food companies keen to see if their products can be made resistant to bacterial attack through alterations to the food's structure. Brocklehurst believes it will be possible to make the emulsions used in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump,

单选题 After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple of Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple's Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the re-opening of the temple, jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carded out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

单选题Tony Huesman, a heart transplant recipient (接受者) who lived a record 31 years with a single donated organ has died at age 51 of leukemia (白血病), but his heart still going strong. "He had leukemia," his widow Carol Huesman said. "His heart—believe it or not—held out. His heart never gave up until the end, when it had to." Huesman got a heart transplant in 1978 at Stanford University. This was just 11 years after the world"s first heart transplant was performed in South Africa. At his death, Huesman was listed as the world"s longest survivor of a single transplanted heart both by Stanford and Richmond, Virginia-based United Network for Organ Sharing. "I"m a living proof of a person who can go through a life-threatening illness, have the operation and return to a productive life," Huesman told the Dayton Daily News in 2006. Huesman worked as marketing director at a sporting-goods store. He was found to have serious heart disease while in high school. His heart, attacked by a pneumonia (肺炎) virus, was almost four times its normal size from trying to pump blood with weakened muscles. Huesman"s sister, Linda Huesman Lamb, also was stricken with the same problem and received a heart transplant in 1983. The two were the nation"s first brother and sister heart tansplant recipients. She died in 1991 at age 29. Huesman founded the Huesman Heart Foundation in Dayton, which seeks to reduce heart disease by reducing children and offers a nursing scholarship in honor of his sister.
