Nowadays，there is a growing 【小题1】 (popular) of Internet surfing on college campus. 【小题2】 increasing number of students，【小题3】 (major) in science，engineering or liberal arts，spend many hours surfing the Internet with keen interest every day.

So far Internet surfing 【小题4】 (attract) college students like magnets（磁铁）for the reason 【小题5】 it is the world of Internet and the world of globalization. First，【小题6】 the global coverage of Internet，we can reach out to and touch anyone at any place of the world. Via Internet, we can send and receive e-mails at any time much faster, cheaper and more effective than 【小题7】 (tradition) means such as telephone, telex and fax. Next, access to the home pages makes it easy 【小题8】 (get) all kinds of information. Finally, by clicking the mouse, we are able to do such important things as shopping, finding jobs, making friends, and downloading files. What's more, Internet offers many chances.

In the Information Age, 【小题9】 is difficult to imagine modern life without Internet. With information technology industry developing 【小题10】 (rapid), successful dot-com companies appeared everywhere. Internet is revolutionizing our economy, our society and our life.

   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？

   Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.

Maybe that doesn’t sound very interesting. But when you’re connected (连接) to the Internet, there are a lot of things you can do. You can send e-mails to your friends, and they can get them in a few seconds. You can communicate with your friends through social software such as QQ, WeChat, and Facebook. You can also do with all kinds of information on the World Wide Web (WWW) .

There are many different types of computers now. They all can be linked to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people or companies, but no one really owns the Internet itself.

There are lots of places for you to surf the Internet. For example, your school may have the Internet. You can explore the Internet to search for useful information or knowledge in your classroom. However, in order to prevent yourself from playing with computer games, you should use it in limited time. Libraries often have computers joined to the Internet. You are welcome to use it at any time.

Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, receiving and sending the information you need. You can buy or sell whatever you want through the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?

   Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules（分子）.

Intelligence Advanced Research Projects Activity（IARPA）announced plans to develop tabletop-sized machines that can store and retrieve（取回）data from large batches of polymers — a term that refers to a wide variety of long，string-like molecules. Polymers can store data in individual atoms or groups of atoms.

The project is an attempt to solve a basic problem of the modern era:the vast and growing costs of data storage. Datacenters around the world sucked up 416. 2 terawatt hours of electricity in 2016. That's about 3 percent of the global supply，and it accounts for 2 percent of global greenhouse gas emissions.

A 2016 paper found that DNA，in particular，could store computer information more densely，require less energy，and survive higher and lower temperatures than conventional hard drives. The authors of that paper reported on the successes of prototype（雏形）DNA computers that used the genetic molecules for both long-term storage and random access memory（RAM）.

But no one has yet figured out how to handle DNA data storage on large scales.

IARPA officials said the new effort, called Molecular Information Storage, will be broken up into three periods:a two-year program to figure out how to store data in DNA or other molecules at high speed,a two-year program to figure out how to retrieve that data at high speed, and a two-year effort to develop an operating system that can run on that DNA.

Many of the technologies IARPA wants to develop are untested at these scales, so it's unclear how far away that proposed tabletop device really is.
