Do you often listen to music at loud volume？Over one billion young people are at risk of hearing loss because of listening to loud noise for long periods of time.Listening to music or watching a TV show at loud volume is harmful to your hearing.
The United Nations has standards for safe listening.It is not safe to listen to sounds that are louder than 85 dB（分貝） for eight hours or 100 dB for 15 minutes.The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB.
Loud noise is harmful to the inner ears.Most of us are born with about 16，000 hair cell（聽毛細(xì)胞） in our inner ears.These cells notice sounds.However，listening to loud noise for a long time can make these cells work too hard and cause some of them to die.This is what causes hearing loss.
Some people might think that their music isn't all that loud.But this can depend on where you are.For example，if you are in a noisy place like the subway，you might turn up your music too loud without realizing it.Later，when you listen to it at the same volume in a quiet place，you might feel uncomfortable.
The "safe level" for most sound is below 80 dB for up to 40 hours a week.A level of 80 dB is roughly equal to the noise of a subway.

2．The size of the British Isles often leads people to think that the languages spoken in its countries of England，Scotland，Wales and Northern Ireland are somewhat the same.At first，visitors are often surprised to find that they have difficulty in understanding the accents and dialects of certain regions.Even in England there are many different dialects.
Experts believe that for most English people，the places they come from are very important to them.Accents are clues to where people were born and where they grew up.Although some people may change the way they speak during their lifetime，most people carry at least some evidence of their accents and dialects throughout their lives.In addition to the regional accents of England，there can also be class differences among the accents.People are often able to make instant and unconscious judgments about a stranger's class by listening to his or her accent.Both the words and the pronunciation of an individual reflect his or her social position.
It is agreed that in England，the kind of English spoken by a person plays a leading role that generally is not important in North America.The importance of accents and their cultural and social relationships are well represented in films and on television in Britain.The film My Fair Lady based on George Bernard Shaw's 1912 play Pygmalion is often said to be a wonderful example of how social class and the accent were，and still are，linked in Britain.

3．Ever since I graduated from high school I've worked in the factories surrounding my hometown every summer.However，making the transformation between school and full-time blue-collar work during the break never gets any easier.For a student like me who considers any class before noon to be unacceptable，getting to a factory by 6 o'clock each morning is suffering.My friends never seem to understand why I'm so relieved to be back at school or that my summer vacation has been anything but a vacation.
There are few people as self-confident as a college student who has never been out in the real world.People of my age always seem to overestimate the value of their time and knowledge.In fact，all the classes did not prepare me for my battles with the machine I ran in the plant，which would jam whenever I absent-mindedly put in a part backward or upside down.
The most stressful thing about blue-collar life is knowing your job could disappear over night.Issues like being laid off and overseas relocation had always seemed distant to me until my co-workers told me that the unit I was working in would shut down within six months and move to Mexico，where people would work for 60 cents an hour.
After working 12-hour shifts（輪班）in a factory，the other options have become only too clear. "This job pays well，but it's hell on the body，" said one co-worker. "Study hard and keep reading." she added.When I'm back at the university，skipping classes and turning in lazy re-writes seems too irresponsible after seeing what I would be doing without school.All the advice and public-service announcements about the value of an education that used to sound stale（陳腐的）now ring true.
My experiences in the factories have inspired me to make the most of my college years before I enter the real world for good.
