听力原文： The earliest libraries existed thousands of years ago in China and Egypt where collections of records on tablets of baked clay were kept in temples and royal palaces. In the western world, libraries were first established in Ancient Greece. For example, Aristotle once had a research library in the 3rd century B. C.

The first library in the United States was a private library, which could only be used by authorized readers. In 1633, John Harvard gave money and more than 300 books to a newly- established college in Massachusetts. In return for his generosity, the legislature voted the school be named Harvard College. The librarian there set rules for the new library. Only college students and faculty members could use the books. No book could be lent for more than one month.

The earliest public library was established in Philadelphia in 1731. Although this library was open to every one, all readers had to pay a membership or subscription fee in order to borrow books. Very few subscription libraries exist today. Some book and stationary stores maintain small rental libraries, where anyone may borrow books for a daily charge. The first truly free public library that circulated books to every one at no cost was started at a small New England town in 1833. Today, there are more than 7,000 free public libraries throughout the US. They contain about 160 million books which were circulated to over 52 million readers.

Historically, the major purpose of free public libraries was educational. They were expected to provide adults with the opportunity to continue their education after they left school. SO the function of public library was once described as "less reservoir than a fountain". In other words, emphasis was to be placed on wide circulation rather than on collecting and storing books. Over the years public library services have greatly expanded. In addition to their continuing and important educational role, public libraries provide culture and recreation, and they are trying to fill many changing community needs. Most libraries offer browsing rooms where readers can relax on comfortable chairs and read current newspapers and magazines. Many also circulate music records. Library programs of films, lectures, reading clubs, and concerts also attract library users. In addition to books, records, periodicals, and reference material, libraries provide technical information such as books and pamphlets on gardening, carpentry and other specialized fields of interests. The largest public library in the US is the Library of Congress. It was originally planned as the reference library for the federal legislature. Today in addition to that important function, it serves as the reference library for the public, and sends out many books to other libraries on inter- library-loan system.

Unlike free pubic libraries, which open to everyone, private libraries can be used only by authorized readers. Many industrial and scientific organizations and business firms have collections of books, journals and research data for their staffs. Several private historical associations have research collections of special interest to their members. In addition, many elementary and secondary schools operate libraries for use by students and teachers. Prisons and hospitals maintain libraries too. The largest and the most important private libraries are operated by colleges and universities, and are used by students, faculty members, and occasionally by visiting scholars. Many universities have special libraries for research in particular fields, such as law, medicine and education. Recent surveys report that more than 300 million books are available in these academic libraries and they are regularly used by over 8 million students.

A．The legislature.

B．The librarian.

C．John Harvard.

D．The faculty members.

Large companies need a way to reach the saving of the public at large(大多数，整个). The same problem, on a small seals, faces practically every company trying to develop new products and create new jobs . There can be little prospect of raising(筹集) the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits. They do this by issuing(发行) stocks and shares in the business through the Stock Exchange (证券交易所). By doing that so they can put into circulation(流通) the savings of individuals and institutions, both at home and overseas.

When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares to some other saver who is seeking to invest his money.

Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function(运作). All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, come to the Stock Exchange.

There is hardly a man or woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another this new money must come from the savings of the country. The Stock Exchange exists to provide a channel (渠道) through which these savings can reach those who need finance.

Almost all companies involved in new production and development must______.

A．rely on their own financial resources

B．persuade the banks to provide long-term finance

C．borrow large sums of money from friends and people they know

D．depend on the population as a whole for finance

Anthropology is the study of human beings as creatures of society. It fastens its attention upon those physical characteristics and industrial techniques, those conventions and values, which distinguish one community from all others that belong to a different tradition.

The distinguishing mark of anthropology among the social sciences is that it includes for serious study more other societies than our own. For its purposes any social regulation of mating and reproduction is as significant as our own, though it may be that of the Sea Dyaks, and have no possible historical relation to that of our civilization. To the anthropologist, our customs and those of a New Guinea tribe are two possible social schemes for dealing with a common problem, arid in so far as he remains an anthropologist he is bound to avoid any weighting of one in favor of the other, lie is interested in human behavior, not as it is shaped by one tradition, our own, but as it has been shaped by any tradition whatsoever. He is interested in a wide range of custom that is found in various cultures, and his object is to understand the way in which these cultures change and differentiated, the different forms through which they express themselves and the manner in which the customs of any peoples function in the lives of the individuals.

Now custom has not been commonly regarded as a subject of any great moment. The inner workings of our own brains we feel to be uniquely worthy of investigation, but custom, we have a way of thinking, is behavior. at its most commonplace. As a matter of fact, it is the other way round. Traditional custom is a mass of detailed behavior. more astonishing than what any one person can ever evolve in individual actions. Yet that is a rather trivial aspect of the matter. The fact of first rate importance is the predominant role that custom plays in experience and belief, and the very great varieties it may manifest.

36. According to the passage, we can say that anthropology ______.

A)can deal with human beings as one group of the creatures in the living world

B) can reveal an enormous diversity of traditions

C) can provide insights into the relationship between human beings and nature

D) can distinguish the human race from other creatures
