Like business and industry, the academic world is changing as technology advances. Libraries are one place we see changes. Many innovative(革新的)things are happening in both public and university libraries. Libraries are using new equipment and techniques for research, and librarians are teaching students the new techniques.
One service that some university libraries are now providing is a computer search of materials for students doing research. Before starting a research project, students check with their library to see if a computer search is worthwhile. This kind of search cannot help with all research projects, but it can save time if the topic is in the computer’s database(数据库). When you are doing a manual search(用手查询)for a research paper, you look at all the indexes(索引)appropriate to the research topic. You look up the words related to the topic in the indexes. It takes many hours to look up this information, and write down the references. A computer search is faster and easier. You and a librarian decide on the words to enter into the computer. Then the computer looks for these words in this database and gives you a list of references for your topic. A computer can take two or more ideas and produce references that combine those ideas. A computer search can also be more complete than a manual search.
College and university libraries are providing other technological services as well. Another change is the frequent use of microfilm. Librarians are able to collect more material in one building by having newspapers, magazines, and other documents on microfilm. Students use microfilm readers(阅读器)in the library for these materials.
These innovations in libraries are helpful to library users, but they are also expensive. Many libraries are facing budget(预算)problems. There is more technology available today; as a result, libraries are paying higher costs for the equipment that makes research easier.
When the computer’s database includes the research topic, ______.
选项
A、computer searches are not helpful with research project
B、computer searches are useless for most kinds of research
C、a computer search for materials is the best way to begin any type of research
D、computer searches can save time
答案
D
解析
第二段第三句话:这种搜索不能说对于所有研究课题都有效,但当数据库中有相应的课题时就可以大大节省时间。因此可以得出D项是正确答案。
