单选题According to new research of Prof. Randolf Menzel from the Free University in Berlin, the popular image of bees as the ultimate hard workers was inaccurate. "Although we see bees buzzing around tirelessly in spring and summer, the common belief in a bee's busy nature is based on a misconception," he said. People only really see bees when they're out flying, or they look at a colony of bees and see thousands of them buzzing around. They don't get to pick them out as individuals. The professor, who this month won a German Zoological Society award for his work on bees, added that bees compensated for their apparent laziness with high intelligence, advanced memory skills and an ability to learn quickly. The suggestion that bees were not pulling their weight met with skepticism from British beekeepers. Glyn Davies, the President of the British Beekeepers Association, said that bees were not lazy but efficient. "At any particular stage in its life, a bee has a specific job to do. If they are unable to do that job, they conserve their energy by doing nothing. Each bee has a unit of life energy and the faster it works, the faster it dies. They are being very wise and perhaps humans should try to follow their example instead of running about like headless chickens. " The idea of the busy bee is several thousand years old. One current author who has nothing but admiration for the bee is Paul Theroux, the novelist and part-time beekeeper. "I have never seen a bee sleeping. My bees never stop working. " he said, Mr. Theroux, who keeps 85 hives each containing 30000 bees in Hawaii, added that Prof. Menzel's research could have been affected by his national origins. "Perhaps in comparison to the German rate of work, the bee does look lazy," he said. Few people think that the busy bee idea will go away, despite the efforts of Prof. Menzel. It performs too many useful functions in our culture. In fact, the worship of hees seems to be undergoing a renaissance. IBM recently ran a series of ads drawing on the " waggle dance" of bees, telling businessmen to "make your business waggle. /

Their friendships, however, tend to be shorter and more casual than friendships among people from other cultures. It is not uncommon for Americans to have only one close friend during their lifetime, and consider other "friends" to be just social acquaintances. This attitude probably has something to do with American mobility and the fact that Americans do not like to be dependent on other people. They tend to "compartmentalize" (划分) friendships, having "friends at work", "friends on the softball team", "family friends", etc.. Because the United States is a highly active society, full of movement and change, people always seem to be on the go. In this highly charged atmosphere, Americans can sometimes seem brusque (无礼的) or impatient. They want to get to know you as quickly as possible and then move on to something else. Sometimes, early on, they will ask you questions that you may feel are very personal. No insult is intended; the questions usually grow out of their genuine interest or curiosity, and their impatience to get to the heart of the matter. And the same goes for you. If you do not understand certain American behavior or you want to know more about them, do not hesitate to ask them questions about themselves. Americans are usually eager to explain all about their country or anything "American" in which you may be interested. So much so in fact that you may become tired of listening. It doesn't matter because Americans tend to be uncomfortable with silence during a conversation. They would rather talk about the weather or the latest sports scores, for example, than deal with silence. On the other hand, don't expect Americans to be knowledgeable about international geography or world affairs, unless those subjects directly involve the United States. Because the United States is not surrounded by many other nations, some Americans tend to ignore the rest of the world.

单选题Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States? Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears a uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity (身份) than to step out of uniform? Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible (可减税的). They are often more comfortable and more durable than civilian clothes. Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least. Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.
