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.

Bad Things About Cell Phones in School

Giving your schoolchild a cell phone has a very positive effect. 【小题1】 However, at school especially in the classroom, cell phones cause a lot of problems.

The Internet capabilities (联网功能) of phones will make students absent from their tasks. 【小题2】 In addition to sending text messages, smartphones have email and Internet capabilities. All of these features will distract (使分心) children from their tasks at hand.

【小题3】 The most common means by which the whole class distraction happens is when a cell phone rings during the middle of a class, attracting students’ attention towards the noise. A student with a cell phone may also encourage others to play the game on his cell phone or share information that comes up on the Internet.

The use of phones may contribute to the students’cheating in the exams. Students can take advantage of cell phones’ Internet capabilities to look for answers to questions for tests for which they haven’t studied. Having a palm-sized computer may give students the chance to cheat in exams. 【小题4】

Using a phone may reduce children’s social behavior. If a student has a cell phone, particularly one with an Internet connection, it must reduce his necessity to socially communicate with others. 【小题5】

   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？

   A lot of people say math is not their strong suit. One New Jersey parent wants to help change that. Laura Overdeck grew up with numbers. She always helped measure ingredients（食材）when her mother baked，and she learned about angles from her father. She went on to major in astrophysics（天体物理学）in college. Overdeck wanted her own children to be good at math，too.“And when our first child was about two，we just started giving her a math problem every night，”Overdeck said. The problem was usually a story，involving animals，cars or candies that let the kid count.“Our third child started，at age two，yelling that he wanted his own math problem because he saw his brother and sister doing it. And we thought，‘Wow，we have a household where math is the popular thing at bedtime，’”Overdeck said.

In February，Overdeck set up Bedtime Math，an Internet website where she posts daily puzzles for children. Overdeck is particularly keen to hook（吸引）children on numbers before they go to school. So why introduce little ones to math so early？

Sian Beilock，an expert on performance anxiety，says the more fun and familiar math is early on，the less likely children will feel nervous when they start to learn math in school.“My lab has shown recently that kids as early as first grade report feeling anxious about doing math，”Beilock said.

“You can hear totally educated adults say，‘You know I’m just not that good at math.’or‘I’m kind of afraid of math.’And that’s a totally acceptable thing for a well-educated person to say，but you never hear them say，‘Well，you know，I’m just not that good at reading.’，”Overdeck said. She wants children and their parents to become as fluent in numbers as they are in Harry Potter.
