A

At one time, computers were expected largely to remove the need for paper copies of documents(文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.

Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.

Does all this mean environmental concerns(环境问题) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. I guess people believe that the problem is taken care of, because of recycling(回收利用), said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity.

The action group has also found acceptable paper made from materials other than wood, such as agricultural waste. 31. The growing demand for paper in recent years is largely due to ____. A. the rapid development of small businesses B. the opening up of new markets C. the printing of high quality copies

D. the increased use of the Internet 32. Environmentalists believe one possible way of dealing with the paper situation is ____. A. to encourage printing more quality documents B. to develop new printers using recycled paper C. to find new materials for making paper D. to plant more fast-growing trees 33. Hewlett-Packard Co. has decided to develop new technologies because ____. A. people are concerned about the environment B. printers in many offices are working overtime C. small companies need more hard copies D. they see a growing market for printers 34. What would be the best title for the text? A. Computers and Printers. B. E-mail and the Business World. C. Internet Revolution and Environment. D. Modern Technology and New Markets. B

Your friend might be in Australia or maybe just down the road, but they are all just a few clicks away. Life has changed for millions of teenagers across the world who now make friends online. Whether you use chat room, QQ, MSN or ICQ, you are part of virtual community.

“I rarely talk with my parents or grandparents, but I talk a lot with my old friends on QQ,” said Fox’s Shadow, the online nickname used by a Senior 2 girl in China. “Eight percent of my classmates use QQ after school.”

QQ is the biggest messaging service in China. A record 4 million people use it one Saturday night in October, according to Tencent, the company which developed QQ.

And Fox’s Shadow might well have been one of them. “I log in on Friday nights, and Saturdays or Sundays when I feel bored. I usually spend about 10 hours chatting online every week,” she said. “But I rarely talk with strangers, especially boys or men.”

Even though she likes chatting, she is careful about making friends with strangers online. “You don’t know who you’re talking to. You should always be careful about who you trust online.”

Many people would like to meet offline when they feel they have got to know someone very well. Fox’s Shadow once met one of her online friends face to face. It was a girl who was a comic fan like herself and they went to a comic show together.

However, not all teenagers have been so fortunate. At the beginning of this year, a 17-year-old girl in Liaoning Province was raped after meeting a friend she had found on QQ.

A 16-year-old Beijing boy, known online as Bart Simon, dislikes QQ users. “I used to chat on QQ, but I found that most people were talking nonsense.” he said. Now he chats online in English, using MSN. “I only chat online because I’ve got friends in Japan, the US and Singapore,” he said, “I want to learn more about foreign cultures.” But he spends little time chatting as he sees it as a waste of time and money.

“If you are really addicted to it sometimes you just can’t concentrate in class,” he said.

“And the friends in your real life are always more important than those so-called friends you meet online.”

35. How many messaging services have been mentioned in the passage?

A. 2 B. 3

C. 4

D. 5 36.What’s the meaning of the phrase “log in” in the fourth paragraph?

A. Take off.

B. Get online.

C. Set out.

D. Set up. 37.What is the best title of the passage?

A. Chat Online.

B. Caught in the Web.

C. Do You Know Messaging Service?

D. QQ, MSN, and ICQ.

Computers and Our Life Good morning, ladies and gentlemen! I’m very glad to be here today to give you a short speech about computers and our life. I hope you will like it. With recent economic development, computers have become more and more important in our life. First, we can work more efficiently. Second, we can go online and get connected with our friends. Third, if we need any information, we can use the computer to look for it on the Internet. It is convenient and easy.

A coin has two sides, though. Computers have some bad effects as well. For example, some students have wasted a lot of valuable study time playing games. Also, people who use computers too much can become near-sighted.

In short, I hold the view that we should avoid the bad effects they may bring, while making good use of computers.
