阅读理解To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. It was first used as a shade against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C. We know that the umbrella was also used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use; it became a symbol of honor and authority. In the Far East In ancient times, the umbrella was allowed-to be used only by royal people or by those in high office. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrellas as protection against the rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in 16th century. And again it became a symbol of power and authority. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn''t until the twentieth century that women''s umbrellas began to be made in a variety of colors.

阅读理解Passage 1 Questions 1 to 5 are based on the following passage: According to a recent surv, ey, employees in many companies today work longer hours than employees did in 1979. They also take shorter vacations than employees in 1979. It seems that Americans are working harder today than ever before. Or are they? A management consultant, Bill Meyer, decided to find out. For three days, he observed an investment banker hard at work. Meyer wrote down everything the banker did during his long workday. At the end of the three-day period, Meyer reviewed the banker's activities with him. What did they find out? They discovered that the man spent 80 percent of his time doing unnecessary work. For example, he attended unnecessary meetings, made redundant (多余的) telephone calls, and spent time packing and unpacking his two big briefcases. (76) UApparently many people believe that the more time a person spends at work, the more he or she accomplishes. /UWhen employers evaluate employees, they often consider the amount of time on the job in addition to job performance. Employees know this. Although many working people can do their job effectively during a regular 40-hour work week, they feel they have to spend more time on the job after normal working hours so that the people who can promote them see them. A group of headhunters (猎头) were asked their opinion about a situation. They had a choice of two candidates for an executive position with an important company. The candidates had similar qualifications for the job. For example, they were both reliable. One could do the job well in a 40-hour work week. The other would do the same job in an 80-hour work week just as well. According to a headhunting expert, the 80-hour-a-week candidate would get the job. The time this candidate spends on the job may encourage other employees to spend more time at work, too. Employers believe that if the employees stay at work later, they may actually do more work. However, the connection between time and productivity (生产率) is not always positive. (77) UIn fact. many studies indicate that after a certain point, anyone's productivity and creativity begin to decrease. /USome employees are not willing to spend so much extra, unproductive time at the office. Once they finish their work satisfactorily, they want to relax and enjoy themselves. For these people, the solution is to find a company that encourages people to do both.
