一、阅读理解(共4道试题,共40分。)
1.
Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the country’s resources which can be combined with other resources to produce the goods and services required by the community.
Though the size of the workforce relies on the size of the total population, there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural increase, i.e. the number of births greatly exceeds the number of deaths, then as a total population increases the proportion in the workforce declines.
Sometimes a population is described as aging, which means the birth rate is either falling or growing very slowly, and as people retire from the workforce there are inadequate numbers of young people entering it to take the place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.
The age distribution of population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services for the retired group. If the aged are to be cared for in special homes or hotels, finance must be available for that purpose. If the size of the workforce is little relative to the total population, then the government tax receipts are relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.

A.  people who are available to work and earn income

2.April Fool’s Day is traditionally a day to play practical jokes on others, send people on fool’s errands(差事), and fool the unsuspecting. No one knows how this holiday began but it was thought to have originated in France. The closest point in time that can be identified as the beginning of this tradition was in 1582, in France. New Year was celebrated on March 25 and celebrations lasted until April 1st. When New Year’s Day as changed from March 25 to January 1st in the mid-1560’s by King Charles IX, there were some people who still celebrated it on April 1st and those people were called April Fools.
Tricks performed on April Fool’s Day range from the simple to the elaborate. Setting a roommate’s alarm clock back an hour is common. The news media even gets involved. For instance, a British short film once shown on April Fool’s Day was a fairly detailed documentary about “spaghetti farmers” and how they harvest their crop from the spaghetti trees. Whatever the prank, the trickster usually ends it by yelling to his victim, “April Fool!” April Fool’s Day is a “for-fun-only” observance. Nobody is expected to buy gifts or to take their “significant other” out to eat in a fancy restaurant. Nobody gets off work or school. It’s simply a fun little holiday, but a holiday on which one must remain forever vigilant(警惕的), for he may be the next April Fool!
Each country celebrates April Fool’s differently. In France, the April Fool’s is called “April Fish”. The French fool their friends by taping a paper fish to their friends’ backs. In England, tricks can be played only in the morning. If a trick is played on you, you are a “noodle”.

3.The resources of the library can be helpful even when we are doing something very informal, such as trying to devise a better way to measure attitudes toward music or looking for a better way to teach mathematics. The library can be equally helpful when we are doing something very formal, such as writing a dissertation (学位论文) or preparing an article for publication in a professional journal. In either case, our goal should be to use the library as a useful tool to help us understand and solve our problem.
    The following sections of this chapter will describe specific resources available in many libraries. In some cases you may already be aware of a resource and may use it frequently and successfully. In other cases you may be completely unfamiliar with a resource. Your goal should be to become aware of what is available and to know how to use each of these resources to help you solve the problem they are designed to solve.
    When educators have a piece of information that they want to share with their colleagues, they often make this information available in professional journals or at professional meetings.

4.When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked the obvious, “Why did she live to be 107” Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most of their lives in cities. In spite of the city’s image as an unhealthy place, city living often provides benefits that county living can lack. One factor seems to be important to the longevity (长寿) of those interviewed.
    This factor is exercise. In the cities it is often faster to walk short distances than to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators (电梯), and so people must climb stairs. City people can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.
    On the other hand, those who live in the country and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere else, they must ride in cars.

1).The Vienna survey may help to explain _______.
A. the complaints of people in apartment houses
