More than 20 Internet service providers in China have joined hands to crack_down_on junk mail that has long plagued(折磨, 使苦恼)e-mail users in China by establishing a coordinated (协调)group, the China Daily reported Tuesday.

The union, connecting such big fish as Sina and 263.net, has agreed to share information on technical solutions, promote public involvement and extend international cooperation, said the newspaper.

The group was collecting information from netizens(网民) on junk e-mail addresses and contents.

"We will then examine the information, leading to the formation of a blacklist that can help block spam (垃圾邮件)sources," Jiang said.

He added that software solutions will also be developed to make it easy for net users to block and delete spam themselves.

But some Internet experts voiced warning, saying junk mail problems will continue to appear in the years ahead, according to the newspaper.

"There are still loopholes(漏洞) in legal, managerial and technological terms which have not yet been patched up," said Qing Sihan, an information security technology specialist from the Chinese Academy of Sciences.

China has had surprising growth in Internet users with their number reaching 45.8 million by this June, ranking the second largest cyber community in the world after the United States, according to the paper.

Unlike traditional commercials, Public Service Advertisements(PSA)are primarily designed to inform and educate rather than sell a product or service. The goal of a PSA is not to make a big sale, but rather to change public opinion and raise awareness for a problem.

Smokey Bear has been a recognized symbol of the protection of America’s forests from fire. It is created to educate the public about the dangers of wildfires. Smokey Bear was started in 1944 with the slogan, “Smokey Bear Says—Care will prevent 9 out of 10 forest fires”. Smokey Bear’s later slogan,  “Remember! Only You Can Prevent Forest Fires”, was created in 1947 by the Advertising Council in America. In April 2001, the message was changed to “Only You Can Prevent Wildfires”.

The wildfire prevention campaign with Smokey Bear is one of the longest and most successful campaigns in advertising history. The Advertising Council often was in partnership with other organizations and groups to create various advertising for Smokey Bear since 1944.

The Advertising Council teamed with Walt Disney Company to create a series of PSAs. The ads feature(以···为形象)characters form the classic film Sleeping Beauty and aim to reach parents and children. The lovely Bambi also appeared in the advertisements. Mickey Mouse is much more popular throughout the country.

Those PSAs, which appear on television, on the radio, in the newspaper and on the website continue to remind Americans about the importance of wildfire prevention have helped to reduce the number of acres burned annually by wildfires. According to recent survey, Smokey Bear and his famous words of wisdom “Only You Can Prevent Wildfires” are recalled by 3 out of 4 adults.

In addition to the PSA campaign, Smokey Bear has his own U.S. postage stamp and website for more information about wildfire prevention. From the website, you can also learn all about wildfires and how we can protect our forests.

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.

Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1. The article is intended to______.  

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

C. convince people of the uses of RFID technology

D. predict the applications of RFID technology

2. We know from the passage that with the help of RFID tags, people        .

A. will have no trouble getting data about others

B. will have more energy for conversation

C. will have more time to make friends

D. won’t feel shy at parties any longer

3. Passive RFID tags chiefly consist of        .

A. scanning devices              B. radio waves   C. batteries              D. chips

4. Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become more fierce.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.

5. The last paragraph implies that RFID technology        .

A. will not be used for such matters as buying milk

B. will be widely used, including for buying milk

C. will be limited to communication uses

D. will probably be used for pop music

When Scotsman Alexander Graham Bell invented the telephone in 1876, it was a revolution in communication.Over the last two decades a new means of spoken communication has emerged: the mobile phone.

The modern mobile phone is a more complex version of the two-way radio.Traditional two-way radio was a very limited means of communication.As soon as the users moved out of range of each other's broadcast area, the signal was lost.In the 1940s, researchers began experimenting with the idea of using a number of radio masts (天线杆)located around to pick up signals from two-way radios.A caller would always be within range of one of the masts; when he or she moved too far away from one mast, the next mast would pick up the signal.(Scientists referred to each mast's reception area as being a separate "cell"; this is why in.many countries mobile phones are called "cell phones".)

The first real mobile telephone call was made in 1973 by Dr Martin Cooper.As soon as his invention was completed,, he tested it by calling another scientist to announce his success.Within a decade, mobile phones became available to the public.They have changed the way we do a lot of things.One powerful feature is the Short Message Service (SMS) or text message.It's the perfect communication method for the busy modern lifestyle.Going to be late? Send a text message! The text message has changed the way we write in English.The language construction became less strict.Traditional rules of grammar and spelling are much less important when you're sitting on the bus, hurriedly typing "Will B 15mm late-C U @ the bar.(I will be 15 minutes late to see you at the

bar.) Sorry!".

Over the last few years mobiles have become more and more advanced.We have seen the instruction of cameras, global positioning system and Internet access.

Alexander Graham Bell would be surprised if he could see how far the science of telephone has progressed in less than 150 years.If he were around today, he might say: "That’s gr8(great)! But I'm busy rite now(I am very busy right now).Will call U2nite(I will call you tonight.)."

The writing style of the passage is a (an)___.

       A.narrative     B.description           C.essay D.review

The article is intended to__      _.

       A.warn people of the possible risks in using mobile phones

       C.convince people of the uses of mobile phones

       D.predict the applications of mobile phones
