单选题If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of year. A noted scientist, Ells- worth Huntington (1876-1947) concluded from other men's work and his own among peoples in different climates that climate and: temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than summer heat is. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that mental, abilities of large numbers of people tend to be lowest in the summer. Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!

单选题{{B}}16-20{{/B}} 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 reopening of the temple, Jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carried out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

单选题The computer has changed the way we work, team, communicate, and play; Virtually ewery kind of organization throughout the world conducts business with computers. Students, teachers, and research scientists use the computer as a learning tool. Millions of individuals and organizations communicate with one another over a network of computers called the Internet. Computer games entertain people of all ages. Almost all computers are electronic digital computers. They are electronic in their use of electric current(电流) to carry information. They are digital in. that they process information as units of electric charge representing numbers. The word digital means having to do with numbers. To enable a computer to process information that is not numerical — such as words, pictures, or sounds — the computer or some other &vice must first digitize: that information. A device digitizes information by translating it into charges that represent numbers. After the computer processes the digitized information by working with the charges, the computer or a device: connected to the computer translates its results hack into their original form. Thus, an artist might use a machine called a scanner to digitize a photograph. The artist would next process the resulting electric charges in a computer to Change the photograph perhaps to add a border. The artist would then use a printer connected to the computer to produce a, copy of the altered photo. Digital computers are one of two general kinds of computers. The other kind is calculating devices called analog computers. An analog computer represents amounts with physical quantities, such as distances along a scale, rather than with numbers.

单选题In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had (21) that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that (22) variation occurs among the social ties of most species, showing that [earning is a part of social life. That is, the (23) are not solely fixed by the genes. (24) , the learning that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly (25) instinctive, but it is not quite like the learning of humans, it is something in between the two. An illustration best (26) the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts. Now we know that. shortly (27) they hatch, ducklings fix (28) any object about the size of a duck and will henceforth follow it. So ducklings may follow a basketball or a briefcase if these are (29) for the mother duck at the time when imprinting occurs. Thus, social ties can be considerably (30) , even ones that have a considerable base (31) by genetics. Even among the social insects something like imprinting (32) influence social behavior. For example, biologists once thought bees communicated with others purely (33) instinct. But, in examining a "dance" that bees do to indicate the distance and direction of a pollen source, observers found that bees raised in isolation could not communicate effectively. At a higher level, the genetic base seems to be much more for an all-purpose learning rather than the more specific responses of imprinting. Chimpanzees, for instance, generally (34) very good mother but Jane Goodall reports that some chimps carry the infant. upside down or (35) fail to nurture the young.

单选题{{B}}Passage Five{{/B}} The most noticeable trend among today's media companies is vertical integration—an attempt to control several related aspects of the media business at once, each part helping the other. Besides publishing magazines and books, Time Warner, for example, owns Home Box Office (HBO), Warner movie studios, various cable TV systems throughout the United States and CNN as well. The Japanese company Matsushita owns MCA Records and Universal Studios, and manufactures broadcast production equipment. To describe the financial status of today's media is also to talk about acquisitions. The media are buying and selling each other in unprecedented numbers, and forming media groups to position themselves in the marketplace to maintain and increase their profits. In 1986, the first time a broadcast network had been sold, two networks were sold that year—ABC and NBC. Media acquisitions have skyrocketed since 1980 for two reasons. The first is that most big corporations today are publicly traded companies, which means that their stock is traded on one of the nation's stock exchanges. This makes acquisitions relatively easy. A media company that wants to buy a publicly owned company can buy that company's stock when the stock becomes available. The open availability of stock in these companies means that anybody with enough money can invest in the American media industries, which is exactly how Rupert Murdoch joined the media business. The second reason for the increase in media alliances is that beginning in 1980, the Federal Communications Commission (FCC) gradually deregulated the broadcast media. Before 1980, for example, the FCC allowed one company to own only five TV stations, five AM radio stations, and five FM radio stations; companies also were required to hold onto a station for three years before the station could be sold. The post-1980 FCC eliminated the three-year rule and raised the number of broadcast holdings allowed for one owner. This trend of media acquisitions is continuing throughout the 1990s, as changing technology expands the market for media products. The issue of media ownership is important. If only a few corporations direct the media industries in this country, the outlets for differing political viewpoints and innovative ideas could be limited.
