单选题To understand how Americans think about things, it is necessary to understand "the point". Americans mention it often: "Let's get right to the point," they will say. "My point is.... What's the point of all this?" The "point" is the idea or piece of information that Americans suppose is, or should be, at the center of people's thinking, writings, and spoken comments. Speakers and writers are supposed to "make their points clear", meaning that they are supposed to say or write clearly the idea or piece of information they wish to express. People from many other cultures have different ideas about the point. Africans traditionally tell stories that express the thoughts they have in mind, rather than staring "the point" clearly. Japanese traditionally speak indirectly, leaving the listener to figure out what the point is. Thus, while an American might say to a friend, "I don't think that coat goes very well with the rest of your outfit," a Japanese might say, "Maybe this other coat would look even better than the one you have on." Americans value a person who "gets right to the point". Japanese are likely to consider such a person insensitive if nor rude. The Chinese and Japanese languages are characterized by vagueness (模糊) and ambiguity. The precision and directness Americans associate with "the point" cannot be achieved, at least not with any grace, in Chinese and Japanese. (76) Speakers of those languages thus have to learn a new way of reasoning and expressing their ideas if they are going to communicate satisfactorily with Americans.

单选题Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists cre-ate too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget bow much tourism can help the country's economy. (79) It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that at-tract tourists. Tourism should also advance the well-being of local inhabitants.Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.On the other hand, if there is not enough tourism, people can lose jobs. Businesses canal so lose money. It costs a great deal of money to build large hotels, airports, air termi-nals, first-class roads, and other support facilities needed by tourist attractions. (80) For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.Building a hotel is just a beginning. There must be many support facilities as well, in-cluding roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tour-ists, jobs and money are lost.

单选题Why don't birds get lost on their long flights from one place to another? Scientists have puzzled over this question for many years. Now they're beginning to fill in the blanks. Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night? Tests with artificial stars have proved that certain night - flying birds are able to follow the stars in their long- distance flights. A dove (鸽子)had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky. (76) The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight. (77) But the stars are apparently their principal means of navigation(航行)only. When the stars are hidden by clouds, they seemingly find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it's too dark to see these, the doves circle helplessly, unable to find their way.
