PROBLEM: Article: After months of fear, hate and prosecution , the music and consumer-electronics industry decided to try to make beautiful music together. Last week the Secure Digital Music Initiative, a combination of 100 music, electronics and high-tech companies announced that it agreed on a music format known as MP3 which caused disagreement. Nowadays, more and more young people are fond of music that is played on their portable MP3 players. So this announcement attracted a lot of attention in both the producer and consumer sides. MP3 allows the digital music in CDs to be made smaller to a tenth its size and still sounds great. MP3 songs are small enough to be traded online; they are made by the millions to the _ of record companies, which fear that everything ever released on disc will end up online for free. Traditional records and their sale may be greatly damaged by this new format of music, and for the music's sake, it is better conveyed in this new medium. That's why the recording industry appealed to the court against little Diamond Multimedia when it started selling a portable MP3 player two years ago. Not only did Diamond win in court, but it also sold 100,000 Rios along the way. With half a dozen other companies racing to produce their own versions of the Rio for Christmas, what could the music industry do? They have no choice in their future, their success just depends on how they can deal with the new trend and cooperate with the electronics companies. It couldn't ignore MP3, which has become the format of choice among new bands trying to advertise their pre-released songs. So the industry agreed on it on one condition: within 18 months, when a standard is adopted that allows piracy-protected music (free from being illegally copied) to be sold online, the electronics companies agree to make their players in line with it. This clears the way for the new magic MP3 players, which is both convenient and capable of carrying on much more music than traditional walkmans. What's next? Digitally pirated movies. Get ready,prefix = st1 /Hollywood.

PROBLEM: Article: Rock and roll music developed in the United States in the early nineteen-fifties. It was based on the music called rhythm and blues that was performed by African American musicians. Early rock and roll singers developed their own kinds of music. Elvis Presley, Chuck Berry, the Beach Boys, and Bob Dylan were the most popular rock and roll musicians in the early 1960's. All were American. Then, in 1964, a new rock and roll group from England invaded America: the Beatles. Some people say the Beatles' music shook America like an earthquake. The Beatles changed rock and roll forever. Their early songs were influenced by American rock and roll musicians, including Chuck Berry. But the Beatles looked different and sounded different from any musical group before them. The Beatles released their first album in the United States in 1964, when all of the top five records in America were by the Beatles. In 1967, they released an album called "Sergeant Pepper's Lonely Hearts Club Band." It was one of the first "concept" albums. That is, all the songs were linked by a common story or idea. The popularity of the Beatles led the way for more rock and roll bands from England to become popular in America. The Rolling Stones was the most important of these bands. The Rolling Stones is one of the few groups from the 1960's that is still performing and recording today. In 1965, the group recorded one of its most famous songs, "Satisfaction". The musical instrument most linked to rock and roll is the guitar. Experts say Jimi Hendrix was one of the most influential guitar players in rock and roll during the late 1960's. His "Purple Haze" was liked by many people. By the 1970's, rock and roll music became known as rock music. It expanded into many new forms. For example, there was country rock, hard rock, acid rock, and heavy metal rock. Punk rock, jazz rock, and glitter rock. In the middle 1970's, experts say rock music regained some of the energy of early rock and roll. Bruce Springsteen and the E Street Band became popular with their album "Born to Run". Springsteen's music was like the lively rock and roll music of the early nineteen-sixties. Many of his songs were about social issues. He sang about the effects of unemployment and the war in Vietnam.

PROBLEM: Article: Printing images is easy. Just select an image of a purple robot on your PC, for example, and press print. Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot's 2-D image. "Printing" 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you. 3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids. So far, few homes have 3-D printers. That's because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they'll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing.
