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.

CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.

The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.

"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.

"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.

The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was.

When skin is exposed to sunlight, notably（尤其）the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.

Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.

The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（紧缩）, reducing blood supply to the skin.

Smoking can also damage the connective tissue (组织)that supports both the skin and the internal organs.

1.The best title for this passage would be_______.

A．The danger of smoking                   B．Smoking causes skin aging

C．Quit smoking for health                   D．A survey of smokers

2.It can be inferred from the study _______ .

A．smoking won’t make skin protected from the sun

B．smoking will do damage to skin rather than other organs

C．smokers over 65 usually won’t worry about their skin

D．the age of smokers is not connected with the result of the test

3. From the passage smoking results in skin aging mainly because_____.

A．it will lower blood supply to skin            B．it can make you feel tired

C．it can make skin come off                 D．it can make blood run faster

4.The main purpose of the passage is to ______.

A．inform people about the result of the study

B．advise people how to protect skin

C．warn people not to smoke again

D．introduce a new way of avoiding skin aging
