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.

Natural ways of keeping time
In ancient times, people had to use the sun and the moon to tell time. They got up when the sun came up and worked in the fields until the sun went down.
Man-made things
The sand clock is made of two glass balls joined by a narrow neck. The top ball was filled with sand. The sand slowly moved through the neck into the bottom ball. People knew how much time had passed when all the sand had fallen to the bottom ball.
People also made the water clock. They made a small hole near the bottom of a pot. Then they filled the pot with water. Markings inside the pot showed how much time passed as the water dripped (滴) out of the hole.
Nature’s Clocks in Living Things
◆Animals’ Body Clock
Animals do not need clocks to know time. They have a way of telling time by their bodies. Birds know when to fly to warmer places before winter. Some animals know when to keep more food for the cold winter months. Some fish know when it is time to move up the river and lay eggs.

第三部分阅读理解（共10小题；每小题2分，满分20分）
Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.
Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not.

The first field season is now over at the hut village of the workmen who built the tombs in the Valley of the Kings．However，the archaeologists working on the excavation(挖掘)have found that they still have a great deal to do．The sun，the wind and tourists have left their mark on the village，originally discovered by Bernard Bruyhre in 1935．
“From our modern perspective，it is upsetting to see how the village was first excavated and then left to be destroyed．Passers-by have used the huts as rubbish dumps and restrooms，”says Jaana Toivari—Viitala，a teacher at the University of Helsinki．“Fortunately，while we still have some surface cleaning to do，conservation are off to a good start．’’
The hut viliage offers rare insight into everyday life in ancient Egypt．
“In the early twentieth century，archaeologists were only interested in the tombs of kings． The workmen’s huts they discovered were seen as a necessary evil in the quest for the real trea sures．’，
“Now several international research groups on different excavations are examining everyday life and work in the Valley of the Kings．This seems to be a trend in archaeology right now．”Toivari-Viitala says．
Her research group wants to find out why the hut village was built on the slope of a mountain，halfway between the construction site and Deir-el-Medina．They are also interested in how many workers lived in the village at a time，when they lived there，and what their role was in the construction work．
“Comparing the names found in the village and in Deir-el-Medina provides useful information．Judging from the construction methods，settlement in the village can be divided into two separate periods：the initial settlement and a later one．”
For the time being，much is up to guessing，but Toivari-Viitala believes that the coming four field seasons，three months each，will see results．
“The working conditions are not nearly as difficult as I thought they would be． The cool winds in the mountains nicely alleviate the heat．”
The research group working on the“Workmen’s huts in the Theban mountains”project is planning to return to the Valley of the Kings in October．

A．Being interested in the tombs of kings．
B．Examining everyday life and work in the Valley of the Kings．
