What is it?
MP3 compresses (压缩) music into small computer—friendly files．You access MP3 music several ways: Tunes can be downloaded from websites that have converted (转变) vast music libraries into MP3．Or you can prerecorded CDs into your PC and convert songs in minutes into MP3．Once MP3 music is on your PC’s hard drive, you can play it through your computer’s speakers, “burn” it onto blank CDs or swap (交换) MP3 files with friends using e—mail．
How much?
Software needed to play and convert MP3 music is often free．It is preinstalled (预先安装)on most new computers or can be downloaded from many websites, including MP3, com．Some MP3 sites are free．Just type at around $50 and can hold hundreds of songs．A blank CD on which you can record music costs about a dollar．
Advantages

Disadvantages
You may find that music at many sites is limited．And some only allow you to listen rather than download offerings．Others let you download music that then can’t be copied to MP3 players．And a growing number of new CDs make it impossible to copy songs to a computer．
【小题1】How can you get Mp3 music?

   As many as one in five US teenagers have some degree of hearing loss, according to researchers.
They say the problem is growing.
Teenagers really don’t pay attention to how much noise they are exposed (暴露) to, Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even slight hearing loss may affect language development,” said Shargorodsky, one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.
“This certainly is big news,” said Alison Grimes, an ear doctor. Hearing loss is very common in old people, Grimes said, but she added that it was worrying to see it happen in the younger age group.
In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could affect learning, said Grimes,.
The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We knew from before that it is difficult to ask this age group about noise exposure – they underestimate (低估) it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.
Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

Starting from April, 2010, you won’t be hearing the word “NBA” on sports programs on CCTV. Instead, sport host will give the full Chinese name when they refer to the NBA – National Basketball Association. You also won’t hear any other English abbreviations (缩略词) on CCTV’s Chinese programs, such as GDP (gross domestic product), or WTO (World Trade Organization). You will hear their Chinese translations.
CCTV received a notice from the State Administration of Radio, Film and Television telling it to avoid using English-language abbreviations in their reports to protect the “purity” of the Chinese language. A few other TV stations also received the notice.
Fu Zhenguo, an editor of People’s Daily, is one of the people who suggested the change. “Firstly, using English in a Chinese-speaking environment is against Chinese law,” he said. “Then, using English on Chinese TV programs is unfair to people who don’t understand English. What’s worse, it will have a bad language influence on kids and teenagers.”
A lot of netizens have criticized the move, saying that it will cause problems for them.
“I understand what CD, VCD and DVD mean when I hear them. But I won’t know what the TV programs are talking about if I hear those products’ full Chinese names,” a netizen wrote in a BBS post. Following the same post, another netizen wrote jokingly: “I’m not listening to my MP3 now. I’m listening to my Moving Picture Experts Group-1 Audio Layer 3 (动态影像专家压缩标准音频第三层面).”
