答案 The Internet is a worldwide communication network that links computers at schools, colleges, businesses, and other sites. The Internet includes collections of information put together by faculty and students at different schools, by government officials, by social service agencies, and, increasingly, by specific businesses or industries. Other sources of information on the Internet are the many discussion groups, or news groups, where people from all over the world exchange ideas on an astounding range of topics. The groups themselves are organized under the name Usenet. If your school is connected to the Internet, you can use the network to locate information such as government documents, discussion groups, electronic journals, library catalogs, as well as complete texts that are in the public domain (works without copyrights or with expired copy- rights). Current works protected by copyright law including practically all books and journals published in the last seventy - five years are unlikely to be available free of charge.
