阅读理解 　　Like business and industry, the academic world is changing with technology advancing．A library is one place where we can 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 man 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(人工的)search for a research paper, you look at all the indexes(索引)suitable for 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(参考资料)．A computer search is faster and easier．You and a librarian decide on the words to enter the computer．The computer looks for these words in this database and gives you a list of reference 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 materials in one building by having newspapers, magazines, and other documents on microfilm．Students use microfilm readers 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(可得到的)today; as a result, libraries are paying higher costs for the equipment that makes researches easier． (1) Before a research begins, students may find out in the library ________． [　　] A． if the computer looks through its database to choose their topic B． if the computer writes out a list of the words they entered C． if a computer search will be useful D． if librarians are helpful to them (2) When the computer's database includes the research topic ________． [　　] A． computer searches are not helpful before the 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 (3) Libraries can keep larger amounts of materials by ________． [　　] A． buying a lot of newspapers B． collecting more information on other university building C． using different indexes from other university libraries D． having microfilm copies of newspapers and other documents (4) What can be concluded from the last paragraph?

Answer 1

答案：1．C;2．D;3．D;4．C;
解析：

(1)	由第二段的句子Before starting a research project, students may check with their library to see if a computer search is worthwhile可以得出答案：学生可以跟图书馆合计一下，看电脑搜索是否有必要．
(2)	由第二段的句子…it can save time if the topic is in the computer's database得出答案：假如这个题目在电脑的数据库里，电脑搜索就能节省时间．database数据库．
(3)	由第三段可知，本段主要说明microfilm在图书馆里的用途，所以选D．(Another change is the frequent use of microfilm．Librarians are able to collect more materials in one building by having newspapers, magazines, and other documents on microfilm．Students use microfilm readers in the library for these materials．)microfilm微型胶卷．这里说明，图书管理员可以把更多的材料存入微型胶卷，然后学生可以借助微型胶卷阅读器读取里面的信息．
(4)	These innovations in libraries are helpful to library users, but they are also expensive．是最后一段的主题句．innovations革新．图书馆里的这些革新在方便读者的同时，也增加了成本．
