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.

During his life Dr James Naismith worked as a doctor, taught P.E and wrote several books. While he never thought it very important, Dr Naismith is today best known for one thing. He was the inventor of basketball.
Dr James Naismith was born in Canada in 1861 and his first job was at a special sports school in the USA. One day the school principal told James he was having a problem with the students. Because of heavy snow, the students could not go outside. He told James that they needed a sport the boys could play indoors and gave the teacher two weeks to think of something.
It was on the very last day that James came up with his idea. The “birth of basketball” is said to be on December 21, 1891, when two teams from the school played the first game. It was quite different from the basketball games of today. It had 9 players on each team and footballs were used instead of basketballs. Soon after, the game changed to 5 players on each side, using special “basketballs” through nets.
Although Dr Naismith did not live to see basketball become the worldwide game it is today, in 1936, just three years before his death, basketball became an Olympic sport at the Games in Berlin.

The word doping is probably from the Dutch word dop, the name of an alcoholic drinks make of grape skins used by Zulu soldiers in order to encourage their bravery in battle. The term became current around the turn of the 20th century, originally referring to illegal drugging of racehorses. In 1928 the International Amateur Athletic Federation (IAAF) became the first to ban the use of doping. A reliable test method was finally introduced in 1974.

The practice of enhancing athletes’ performance through foreign substance or other artificial means, however, is as old as competitive sport itself. The most famous doping case of the 1980s concerned Ben Johnson, the 100-meter champion who tested positive for stanozolol(司坦咗醇) at the Olympic Games in Seoul, 1988.

The main front in the anti-doping war has rapidly shifted to blood doping since 1970s. Blood doping is the practice of adding red blood cells to the bloodstream in order to improve athletes’ performance. The blood is usually processed in order to create a concentration of red blood cells, and then freeze them until needed for transfusion(输血) back into the athlete shortly before the event. The extra red blood cells will deliver more oxygen and other essential elements to the athlete’s muscle tissues.

Just like any other problem, the only way to solve it is through education. Many high school sports programs now have people come in to talk to them about out the dangers of performance-enhancing drugs. Young players must be fully clear on the rules and what substances are banned. The NCAA (National Collegiate Athletic Association) has an easily accessible list of what substances are banned, how they are tested for and why they are banned on its website. This way, young players are clear on what they can put in their bodies. This is also a good way to educate players on the danger of the substances they may be tempted to use.

1.The word “enhancing” in the first sentence of the second paragraph means “_____”.

A.showing

B.directing

2.What can we know from the third paragraph?

A.Blood doping is transferring one man’s blood into another

B.Only blood doping exists in the anti-doping war in the 1970s.

C.Blood doping is easy to be found and controlled by organizations.

D.More oxygen in the blood helps improve an athlete’s performance.

3.The word “people” in the second sentence of the fourth paragraph probably refers to _____.

A.teachers who teach P.E. lessons at school

B.experts who do research in doping

C.young people easy to be addicted to doping

D.athletes involved in doping

4.Which statement best matches the last paragraph?

A.Prevention is better than cure.

B.Reading is to the mind what exercise is to the body.

C.The best horse needs breaking, and the cleverest child needs teaching.

D.A little learning is a dangerous thing.
