Article: When people talk of a virus these days, chances are that they are talking about computer virus that have the power wipe out all the valuable work people may have stored in their computers. Imagine, the virus has the power to make military systems, giant banks, airports, hospitals and traffic system come to stop! What does a computer virus do? It targets electronic objects that are programmed. The virus spreads through connections between these electronic objects. For virus spreading experts, e-mail is a favorite method of sending their destructive weapon. But scientists warn that this is not the worst that can happen. There is more. People are also connected through phones. The next virus may actually target mobile phones, especially those that are programmed to do many tasks apart from just communicating. It would then be easy for a virus to infect those programs and create major disorder. For example, these virus may have the power to record your phone conversations and make others hear them. They create problems with your electronic money accounts, or they could create a mountain of telephone bills for calls you never made. And that would be a disaster. A report on this was published in the New Scientist recently. One way out would be to have simpler phones with not so many different functions. This would mean there would mean there would be fewer programs for the virus to attack. But mobile phone producers are _ . People on longer want an electronic item to perform just one task. They want more and more functions added. That would mean more software programs to make the mobile phone perform all those functions. And that means the possibility of more viruses. Question: For whom is the passage written? - Government officials - Virus spreading experts - Electronic scientists - Mobile phone users

Article: Advertisement is the difficult business of bringing information to great numbers of people.The purpose of an advertisement is to make people respond to make them react to an idea,such as helping prevent forest fires,or to make them want to buy a certain product or service.At the beginning of the 20th century,advertisement was described as"salesmanship in print".If this definition were expanded to include radio and television,it would still stand today.The most effective way to sell something is through person-to-person contact.But the cost of person-to-person selling is high because it takes a great deal of time,and it increases the cost of the product or service.Advertising distributes the selling message to many people at one time.The first printed advertisement in the English language appeared in 1278,more than a century before Shakespeare's first play was produced.This early advertisement was the work of William Caxton,England's first printer,who used it to advertise religious books from his own workshop Caxton posted small printed notices along London's main streets.Besides advertising his product,he identified his shop with a red-striped shield so that customers could find it easily. This same sort of simple informational advertising is still used.Examples are the roadside signs that tell travelers that they can buy fresh corn just down the road or that there is a restaurant in the next town. The Industrial Revolution,in the 18th and 19th centuries,brought a new kind of advertising.Large factories took the place of small workshops and goods were produced in large quantities. Manufacturers used the newly built railroads to distribute their products over wide areas.They had to find many thousands of customers in order to stay in business.They couldn't simply tell people where shoes or cloth or tea could be bought---they had to learn how to make people want to buy a specific product. Thus modern advertising was born. Advertising created new markets and helped to raise standards of living as people came to...

Read the following article and select the best answer. Article: I no longer run for the mail the way I used to. I remember, prior to the e-mail age, the sense of heightened expectation as the hour of mail delivery approached, wondering what slender , handwritten treasures would appear in my box. I once received a letter from a long-lost friend and swelled with such joy that I ran the mail carrier down and shook his hand, as if he had done a heroic deed in conveying the missive to me. I first learned to love the mail as a young boy. The first thing I ever received that was personally addressed to me was from my friend Duane. We had been the closest of 9-year-old boys. Then he moved away, to Massachusetts. The parting was difficult, but boys didn't cry. Within the week, however, there was a letter in my mailbox. It was from Duane, and it read, "I'm OK, but I miss you." That first conveyance to me of a written word from a great distance had all the significance of the first Morse code message: "What hath God wrought." It was at that moment that I became a letter writer, quickly discovering that the more letters I wrote, the more I received. I wrote letters through elementary school, high school, college, and beyond. It got to the point where I could comfortably expect to receive a letter a day. _ - something toward which my thoughts began to move upon waking. What quickened my blood, of course, was the element of surprise: From whom would the letter be today? And what would the news be? And then, seemingly in the blink of an eye, the earth shifted. E-mail had arrived. Despite being fascinated by the new technology, I promised myself that I would never stop writing letters by hand. However, I had no control over the habits of others, and slowly, inexorably , and then with quickened pace, the letters disappeared from my mailbox, having been replaced with electronic "messages" , a totally different beast --in contrast to letters, all e-mails look alike. Question: What made the author become a letter writer? - A letter from a long -lost friend. - The desire to receive more letters. - The joy of reading the first letter from Duane. - The influence of the first Morse code message.
The joy of reading the first letter from Duane.
