During recent years, curious private citizens and businesses are crowding onto the Internet at a speed that is doubling its size every year. Now, computer networks have spread to form a giant global Web. Some 100 million people from over 140 countries around the world have logged on to the Internet, a system linking tens of thousands of networks filled with information, discussion and entertainment. Millions of Web pages contained in a great number of sites are commonly used to exhibit a mixture of text, graphics, sounds and video clips, as well as links to other Web pages. On a typical day, data, as much as several million 250-page books, will pour through the Internet. Stored in the system are huge amounts of scholarly and scientific data, government documents and public records, airline timetables, weather reports, the full text of the Bible, and thousands of newspapers and magazines from around the world. In addition, by creating communities of people sharing common interests, computer networks are making their influence felt in schools, in the business world, in politics and government. 本题测试关于“谁”的细节内容的理解。虽然几个选项在文中都有所提及，但从文中第一句就可以听出首创者应为“the U．S．Department of Defence”美国国防部)，因此正确答案为C。 in the event of=in case of如果发生，万一发生 log on=log in＜计＞进入系统 log off＜计＞退出系统 clip n．剪辑：从电影胶片或录像带剪出的片断 scholarly adj．学术的，博学的，学者气质的 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
