However,
8、 peoples opinions are still divided on this point. Those who are in favor of the Internet claim that it has a lot of advantages. Firstly, information searching is no longer a tough job with the help of all kinds of search engines. Secondly, we can contact friends or business partners via e-mails or
9、software such as Internet Meeting and Yahoo Messenger. Last but not least, we can take part in groups or mailing lists to talk with friends of the same interest.,Those who are opposed to the Internet hold that disadvantages are many. In the first place, the Internet costs considerable time, money an
10、d energy especially for those with less self-control. In the second place, surfing on the Internet for a long time harms the eyes a lot.

And it gives consumers the ability to shop smarter, to find the best products at the right prices. In fact, it empowers them in ways that once were available only to large compani

38、American universities and research labs, ITAC has particularly proposed in their report for a strategic initiative in “visionary and high-risk” IT projects. These projects fall into four areas for development: large software systems, the design and operation of large information networks, computer d

In addition, the report has suggested a variety of management structures for the initiative so as to keep America s competitive edge in IT industry.,Summary,CS-P1.2,CS-P1.2,Listening Practice,Directions: Listen to the following passage. And decide whether
40、the following sentences are “T” or “F”.,In an Internet chat room, kids are advised not to ask other peoples names, addresses and phone numbers. Its hard for a stranger to collect details about a kid because they have no chances to talk about themselves. The Childrens Online Protection Act allows Web

43、 such information as the schools they attend or even churches or community centre they belong to. Its not hard for a stranger to collect details about a kid if he pays special attention to the kids words in a chat room. Much of what Ive read about protecting young people from online dangers places t
44、he responsibility on everyone except the kids themselves. For example, the Childrens Online Protection Act requires Web sites to obtain parents permission before collecting information from children under 13. Though thats a good practice for sites to follow, its an even better practice for parents t
45、o explain to their kids why they shouldnt give Web sites information in the first place.
