Behind the success of the product, which was used to write this article, lies military technology. Traditionally, speech recognition systems have been limited in use because they must be treated with care and dictated to slowly with no interfering background noise. In addition, previous systems have had to get accustomed to the voice of an individual user. The Speech Machine's system can operate in high-noise environments and will usually recognize voices immediately. Features like this were developed by the Defense Research Agency.

Users must dictate punctuation marks, such as "comma" and "new paragraph" which the system recognizes as such rather than writing the exact words. The finished document can also be faxed to clients or to the user's base office. The benefit of the service is that it requires no extra training for users. Many professionals already know how to dictate documents because they do it all the time. Using the Net, the clients and typists can be anywhere in the world and the service will run 24 hours a day.

mputer-based worldwide information network. The Internet is composed of a large number of smaller interconnected networks called internets. These internets may connect hundreds or thousands of computers, enabling them to share information with each other and to share various resources, such as powerful super computers and databases of information. The Internet has made it possible for people over the world to effectively and inexpensively communicate with each other. Unlike traditional broadcasting media, such as radio and television, the Internet is a decentralized system. Each connected individual can communicate with anyone else on the Internet, can publish ideas, and can sell products with a minimum overhead cost. In the future, the Internet may have a dramatic impact on higher education and business as more universities offer courses and more companies offer goods and services on-line.

The internets from which the Internet is composed are usually public access networks, meaning that the resources of the network can be shared with anyone logging onto, or accessing the network. Other types of internets, called intranets, are closed to public use. Intranets are the most common type of computer network used in companies and organizations where it is important to restrict access to the information contained on the network.

During the 1990s, the Internet has grown tremendously in the number of people using it and the amount of information contained on it. According to the Internet Society, a non-profit society that studies and promotes the use of the Internet, 134 countries had full Internet connection and an additional 52 countries had limited access(for example, E-mail only)in 1996. Some surveys found that as of September 1997 there were between 53 and 57 million users of the Internet worldwide.

A．The Internet is different from television in which it's more convenient.

B．The Internet may greatly affect the ways of college education and business.

·Read the article below about e·mail phone and the questions on the opposite page．

·For each question（13-18），mark one letter（A。B。C，or D）on your Answer Sheet．

Do you send and receive more phones calls or e—mails？If your answer is e—mail．or you wish it were，then a new breed of telecommunication devices called an e—mail phone or Internet phone may soon find its way into your kitchen or living room．Essentially，an e—mail phone，or e—phone for short．is the merger of telephone and computer．With most of these new screen phones，that means being able to read and reply to electronic mall directly from the phone，without starting up（or even owning）a PC．With some，it also means being able to search through the web to make vacation plans or research homework assignments though at slow speeds and on a rather small screen．And you can still make phone calls，too．

No computer experience is required to use an e-phone．Most let you sign up with Internet Service Provider（ISP），which typically charges about$20 per month．Once you’re past tllis tedious work and enter the account information into the phone，you can check your e—mail from either your computer or phone．

To assess your e—mail account from one of these phones，you typically have to select e—mail service from a menu．Phones with touch screens have an icon（图标）for that on the opening screen．For other phones，you press one of the buttons lining the bottom or sides of the display，much as with an ATM machine．The phone then calls your ISP．When the ISP picks up，the phone automatically transfers your account name and password．Once accepted，the ISP will start sending the phone your messages．By touching the item you want to read or hitting a button next to it，the message will be displayed．Once you’ve read it，you can reply to the message，move onto the next one，or，like most phones，delete the message from your account．You can check your e—mail manually，but most e-phones call also be set to check several times a day automatically．In automatic mode，the phone fla．shes to tell you mail is waiting．If you happen to be using the phone when it is scheduled to check for e—mail，the phone will automatically try again when the line is free．

One serious drawback to e—mail by phone is that it cannot receive（or send）attached files。whether they contain documents or graphics．Some phones will attempt to display simple text files as part of the message，but other types of files will appear as gibberish（乱码），or not at all．If you share the e-mail account with a PC and don’t delete the message，however，you can usually retrieve the message and file on your computer．
