The first MP4 player was born years ago. Soon many music fans were wondering how fantastic it is! If you have been into technology enough, perhaps you may have a knowledge of the MP4. If not, you do need to know something before buying one, even if you are familiar with MP3. MP3 is the CD-like disc with greater capacity. How about MP4? This small digital product will really enrich the joy from listening to music. You can even feel the “touch” of music to your soul!

Now, some similar digital products advertised as “MP4 player” are simply MP3 players, which do not play video and MPEG format and also lack other particular functions. These products confuse some buyers, as they may think the “MP4” players simply mean they can do more than MP3.

What is MP4?

It is a multimedia container. It is not only used to store digital audio and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles and pictures. As a most modern container format, it allows streaming over the Internet.

With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality. By installing DVD-MP4 software, you can transfer particular music from a DVD to an MP4 video file. It really excites your listening music experience.

Then, there is MP4 advanced and you can set your own collection of all the programs—TV shows, games, and music. You can even see movies which are still running in cinema. What else digital product could you possibly ask for?

1. It is suggested here that you should ______ before buying an MP4 player.

Millions of youngsters across Europe could suffer permanent hearing loss after five years if they listen to MP3 players at too high a volume for more than five hours a week, EU scientists warned.

The scientists’ study, requested by the European Commission, attacked the concept of “leisure noise,” saying children and teenagers should be protected from increasingly high sound levels---with loud mobile phones also coming in for criticism（批评）.

“There has been increasing concern about exposure from the new generation of personal music players which can reproduce sounds at very high volumes without loss of quality,” the Commission, the EU’s executive arm, said in a statement.

“Risk for hearing damage depends on sound level and exposure time,” it said. More and more young people were exposed to the great threat(威胁)that leisure noise posed to hearing, it said.

Commission experts said that between 50 and 100 million people listen to portable music players on a daily basis.

If they listened for only five hours a week at more than 89 decibels(分贝), they would already be beyond   EU limits for noise allowed in the workplace, they said. But if they listened for longer periods, they risked permanent hearing loss after five years.

The scientists calculated the number of people in that risk category at between five and 10 percent of listeners, meaning up to 10 million people in the European Union.

Sales of personal music players have soared in EU countries in recent years, particularly of MP3 players.

"I am worried that so many young people ... who are frequent users of personal music players and mobile phones at high acoustic levels, may be unknowingly damaging their hearing ," she said in the statement.

1.Which of the following can be the best title of the article?

A. Youngsters across Europe: suffer permanent hearing loss.

B. MP3 players: sell best but do harm to youngsters

C. The scientists’ study: requested by the EU

D. EU warns youth: turn your MP3 players down!

2. This passage is most likely to be taken from a _________.

3.The underlined part in the forth paragraph most probably means________.

A. were uncovered                     B. felt                   C. realized           D. were faced with

4.From the passage we know that________.

A. besides the high sound levels, scientists also criticized loud mobile phones.

B. if one listened for 5 hours more a week at 100 decibels, he would risk permanent hearing loss.

C. it is only the level of the sound that can do damage to hearing.

D. the scientists said there were 5-10 percent of MP3 listeners risking hearing loss around the world.

【小题1】. It is suggested here that you should ______ before buying an MP4 player.

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 to(接触),” Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even very little hearing loss may influence 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 influence 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 know from before that it is difficult to ask this age group about noise exposure – they underestimate 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.
