Ⅵ.阅读理解

Most children now chat daily either online or through their mobile phones. They are connecting to a huge number of other children all over the world. Some are shy “in real life” but are confident to communicate with others online; others find support from people of their own age on relationship problems, or problems at home.
Sometimes the online world, just like the real word, can introduce problems, such as bullying or arguments. Going online is great fun, but there are also a few people who use the Internet for offensive (冒犯性的) or illegal (非法的) aims. Children must be made aware of both the good things and the danger.
To keep children safe your management must cover the family computer. Just as you decide which TV programs are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕)．
Computer studies are part of school work now, so it's likely that your children may know more than you do. We get left behind when it comes to the latest gadgets (玩意儿) and interactive areas of websites, like chat rooms and message boards, which are especially strange. The language of chat is strange to many parents, too. Chatters love to use abbreviations such as: atb — all the best; bbfn — bye by for now; cul8er — see you later; gr8 — great; idk — I don't know; imbl — it must be love; kit — keep in touch; paw — parents are watching; lol — laugh out loud; xlnt — excellent!

A. careful B. proud
C. to know D. to hear
答案与解析　C　从其次段叙述可知，网络世界中存在冒犯性的和非法的目的。必需使孩子清楚生疏到网络的好处和危急。C项正确。
3．Which of the following will the author probably agree with?
A. Children shouldn't chat so much online.
B. People had better not use the net language in real life.
C. Parents are advised to choose suitable websites and chat rooms for their children.
D. Children should surf the Internet together with their parents.
答案与解析　C　文章重点在讲网络世界存在风险，孩子父母应当尽到责任，使孩子可以健康的上网。C项符合文章中心思想。
