In the last thirty years, the Internet 【小题1】 (grow) rapidly. In 1983, there were only 200 computers 【小题2】 (connect) to the Internet; now there are around 50 million and this growth is 【小题3】(clear) going to continue.

Some experts are pessimistic about the future. One worry is crime in cyberspace. Even now, young 【小题4】 (hacker) can get into the computers of banks and governments. In the future, terrorists may “attack” the world’s computers, cause chaos, 【小题5】 make planes and trains crash.

However, many people are 【小题6】 (optimism) about the future of the Internet. Already, users can buy books, find out about holiday offers, book tickets, and get all sorts 【小题7】 information from the Internet.

“In the next few years,” says Angela Rossetto of Cyberia magazine, “【小题8】 is clear that we are going to see a huge 【小题9】 (grow) in shopping on the Internet.” She also believes that, in the future, we will get entertainment from the Net and that television will probably 【小题10】 (appear). The mail service may also disappear with the increasing use of e-mail.

   Robyn Lee， a 15-year-old teenage girl who studies at York Community High School， US says she has four friends. But she also has 15 to 20 other friends she considers part of her regular social circle.

“It's like a bad thing to have only one， friend ，”explained Robyn. “If you have one friend， it means only one person likes you. That’s not cool，” she said.

For many years， experts studying teen friendships have known that teenagers prefer to travel in groups. In studies conducted in 1963 and in 1995， researchers found teen friendship groups averaged six people. In 2005， when teens were asked about how many friends they kept in touch with regularly， the average answer was 20.

The change to bigger -group friendships has advantages， such as increasing more connections and improving teens' self-pride by giving them a place to belong.

However， the change also has some disadvantages，say psychologists. “The meaning of friendship is becoming much more complicated，” said Bernardo Carducci， a professor of psychology at Indiana University Southeast.

MaryRose Moss， a 17-year-old in Chicago， knows how she could get more friends. She created a Facebook page when she was 14 and within months ， she had her group of 500 friends.

Text messaging has opened the door to many new connections， she says. “I'm friends with some people that I wouldn't be as close to if it weren't for technology，” said Moss. “It's so easy to send a text to somebody even if you don't know him very well. ”

Some psychologists wonder whether social-networking technology is affecting some skills children once got from making friends in the old-fashioned way.

“In the past， you argued， discussed and reached an agreement， but if somebody disagrees with you now， you can ‘defriend’ him with the click of keys，” said Carducci.

Marianne Boe， a social studies teacher in Chicago ， sees signs of changing friendships in the hallways. Ten years ago， she could easily know groups of girls who stayed friends through all four years of high school. “Today， it's harder，” Boe said.

   With the development of modern science and technology，the functions of cellphones have changed greatly.【小题1】 The only difference may be that they fit in your pocket and you pay by the minute to use them.Some of the things a cellphone can do for you will be available this year：

Surf at speed

Cellphones that let you use the Web have been around for years.So，what’s new？ Well，faster thirdgeneration (3G) networks that let you surf at anywhere.【小题2】 Possible choices are from IJG Electronics VX 8000 and Motorola V1150.Listen as you go.

【小题3】 There is no doubt that it is about to change.Sony Ericsson’s new W8001 can hold around 150 songs in its 500 MB memory.And Samsung’s SPHV5400 even comes with a 1.5GB hard drive.Mobile phones may eventually replace mini MP3 players，especially for teens.

Camera cellphones are not new either but most of them have limitations： around 1­megapixel (百万像素).However new technology has made 2­megapixel units more common，and 3­megapixel units are showing up soon.Some 2­megapixel models，like Sony Ericsson’s K7501，offer limited zoom and focus controls.【小题4】 Portable TV.

You say you like “watching TV”？ That’s what Samsung MMA700 wants to give you.The new model lets users watch popular TV programmes for a fee.Other choices are Nokia’s 6620， Sanyo’s MM740 and NEC’s N940.【小题5】

The above are just a handful of what you’ll see in the coming months.Further down the road，your mobile phone may play a host of other roles，such as mobile credit card，position locator and so on.So what is there that a cellphone can’t do？

   One of my earliest memories was watching my mom talk on our old phone. I was fascinated that she could talk to someone who wasn't actually in the room with her. 【小题1】 I was wondering how she managed to talk with someone she couldn't see.

That was a long time ago. Later, we had mobile phones that could be carried around the room. 【小题2】 These days I can send an e-mail around the world in a second. My daughter's smart phone has a hundred apps and a dozen social media accounts. She stores all of her information in a mysterious place known as“the cloud disk”, where she can take it out at any time. It seems that we are more connected in this world than ever before.

【小题3】 Few spend time talking face to face. Instead of looking into the eyes of our loved ones , we store their photos at our screens. It seems that the most connected generations are also the loneliest.

Don't let technology take our time and ruin our life. Make the time to communicate with each other. Take a walk on the beach with a friend. Have a long conversation with the phones off and the hearts on. 【小题4】

Remember that we are here to love each other,help each other and make this world a better place. 【小题5】 But when it can't, turn it off.

   Most people love to lose themselves in a great book, maybe a classic novel, a modern storybook or a great work of history. But many people also live busy lives, and for them finding time to sit quietly and read is difficult, if not impossible. Fortunately, with the coming of the Internet and high-tech tools like the iPod, more and more people are making literature a part of their lives again.

A very special website now makes it possible for people to listen to books that they simply would not have time to read. The site is called Audible Inc., and it’s the best place to download audio (音频的) books. Over the past few years, hundreds of thousands of these books have been recorded. They include nearly every classic, as well as most newly-published ones. Most of these are read by voice actors who really bring the text to life.

Audible Inc. lets you easily and quickly download a book and load it onto your iPod or other MP3 players, or onto CDs so that you can listen in your car. The site is like Amazon, com, but for audio books. It includes thousands of recommendations (推荐) and customer reviews that are extremely helpful. The site lets you listen to a free piece of each book so you can tell ahead what the narrator (讲述者) sounds like. No wonder that most people who listen to an audio book for the first time are immediately attracted.

This is the perfect opportunity to find out what so many people know about audio books. But be careful — you may become attracted to audio books for life.
