Senior citizens are the first to come to our mind when you think of hearing loss, but in a recent report, hearing professionals worry teenagers will soon outnumber aging adults 1. it comes to living with hearing loss.
The rise in popularity of personal audio devices from iPods to smart phones has had dangerous effect on the ears of those who use them most, teenagers! A research 2. (conduct) by the World Health Organization finds that nearly 50% of teens 3. (fall) into the habit of exposing themselves to unsafe levels of sound so far.
A sound is considered unsafe when it goes beyond 85 decibels (分贝). At that level, it takes just 8 hours of listening over your lifetime to cause damage. The louder the sound is, the 4. (little) time it takes to cause damage. Because hearing loss is 5. (typical) considered a health problem for the elderly, it is difficult to convince already stubborn teenagers that they really are doing damage 6. their ears.
Young adults 7. have been exposed to loud noise over a period of time may have some hearing loss symptoms. Their 8. (able) to learn is compromised, and they may have difficulty developing social skills.
In an effort to help teens better protect their hearing, we suggest 9. (set) volume limits on personal audio devices. 10. is also good to limit the amount of time exposed to noise and to take listening breaks to give the ears a rest.

Five biggest career mistakes young workers make
When you begin to dive into the working world, there are a few common mistakes you should try to avoid.
1.
Whether it is asking for a raise or just voicing an opinion, it is important to stand up for yourself in the office. As long as you do it in a respectful and professional way, your colleagues will be impressed by your confidence.
Goofing off（混日子）
You may think no one is looking at what you are doing all day, but the fact is your computer screen can be seen by all who pass by.2.
Even though your boss may seem relaxed, he is not going to appreciate an employee who seems to care more about his friend’s status updates than his actual work.
Dressing inappropriately
One thing that can either help or hurt you is how you present yourself. If you dress too casually, you could be sending the wrong message to your coworkers. Just because you have it doesn’t mean the office is the place to wear it. 3.
Being late for work
You could be the hardest worker in the office or do extra work at home, but if you are consistently late for work, you give off the impression that you are lazy.4.Your professional reputation is a vital part of getting ahead in your industry and being late for work might be unimportant, but could result in all your hard work being gradually ignored.
Acting too confidently
It is a common problem with young professionals. It is sometimes hard for recent college graduates to change from top-of-the-food-chain seniors to professional “freshmen.” 5.In addition, you must know your place in the company.
A.If you want to be taken seriously, dress seriously.
B.Talking unprofessionally.
C.So it is important to limit the amount of time you spend on non-work-related sites.
D.Being afraid to speak up.
E.Sometimes, it can be difficult to be taken seriously as a young professional.
F.Now that you are out of the college, you must remember to be modest.
G.People notice who stays late and who comes in early and will form an opinion about you.
Differences in time zones complicate international phone calls. But even more important are different concepts of time and approaches to time in different cultures.
People from the USA as well as other North Americans believe “Time is money”. This value of time is rooted in their ancestors. Early in the 17th century, their ancestors arrived on the Atlantic coast, a new, undeveloped land. To survive in the tough environment, they had to struggle day and night. Time meant so much to them that they had not even one second to waste. After decades of struggle, they developed the value of efficient use of time and passed it down. Thus far, the Americans are still eager to finish things quickly and are impatient with too reflective(深思熟虑的) people.
In some countries, the American work style of speeding everything up will have no significance. In the Arab East, the more important you are, the faster service you get. Close relatives take absolute priority; non-relatives are kept waiting. In the Middle East, a deadline, which is often established to show the degree of urgency or importance of work, will do nothing but stop the Middle Easterners from working, because they consider it rude and overly demanding.
Another aspect reflecting different concepts of time is the classification of monochronic-time and polychronic-time by Edward T Hall. People from monchronic(共时性的) cultures, such as the Germans, the Austrians, the Swiss and the Americans, do only one important thing at a time. In polychromic(多元时间模式的) cultures, people such as Arab, Asians and Latin Americans take an entirely opposite approach. They do several things at once. Time commitments, e.g. deadlines, schedules, are taken rather casually and changed often and easily. Miscommuication will arise when people from two cultures contact. Charlies Hawkins, a U.S. teacher, told me that many a time his appointments with Indians were interrupted constantly, not only by private phone calls, but also by long conversations with other people and even the neighbor’s children, which displeased and even annoyed him.
1.Why did the ancestors of the North Americans believe “Time is money”?
A. They had to work efficiently to survive. B. They got the idea from their past generations.
C. They didn’t like to deal with reflective people. D. They formed the habit of finishing work ahead of time.
2.What can be concluded from Paragraph 3?
A. Deadlines will make American people angry.
B. In the Arab East, you’d better speed everything up.
C. Middle Easterners can’t deal with demanding work.
D. People from the Arab East attach importance to relationship.
3.What can we learn about people from monochronic cultures?
A. They tend to interrupt others constantly.
B. They can’t tolerate lateness or interruptions.
C. They are more likely to change their schedules.
D. They like to schedule several activities at the same time.
4.Which of the following would be the best title for the text?
A. The importance of the diversity of culture
B. The relationship between efficiency and culture
C. Different time values in different cultures
D. Monochronic culture and polychronic culture
Disease spread in many ways. An infected person can cough or sneeze on someone nearby, or they can spread germs through a handshake. But sometimes we pick up germs indirectly. A sick person might leave behind bacteria or viruses when they touch a door handle, for example. But what if those surfaces could clean themselves?
Two teenagers from Hong Kong asked themselves the same question. Now they’ve developed a door handle that can kill germs on contact.
The idea is simple. Every time the door is opened, the movement creates power that starts a germ-killing reaction on the handle. In lab tests, their system killed about 99.8 percent of the germs that they spread onto lab dishes covered with their material.
Research by others has shown that door handles in public areas are often home to lots of bacteria and viruses, notes 17-year-old Sum Ming(“Simon”）Wong. He and schoolmate Kin Pong ( Michael ) Li, 18, wanted to design a covering for door handles that would kill germs.
After doing some research, they learned that a mineral called titanium dioxide(二氧化钛）is known to kill bacteria. It’s already used in many products, from paints to desserts. To make their covering, the teenagers made the mineral into a very fine powder.
Titanium dioxide kills bacteria best when lit by ultraviolet(紫外线的）light, says Simon. UV light is found in sunlight. But UV light does not naturally shine on indoor handles or any used at night, so the teenagers light their door handle from within.
To make sure the light reaches the coated surface, the teenagers made their door handle out of clear glass, Each end fits into a bracket (托架).Inside one of the brackets is a strong light-emitting diode(LED). From it comes UV light.
And here’s the interesting part: The power that makes the UV light shine comes from opening and closing the door. The power from the door is then carried by wire to the LED inside the door handle.
The door handle system, Michael and Simon say, might cost no more than about $13 (about 81 yuan) to build.

Pamela Simpson is 53,“not sporty” and has suffered from asthma(哮喘) all her life. Two years ago her son Jay-Teale, now 10, took up BMX(自行车越野赛).“I enjoyed watching him and thought I'd like to try it,” Simpson recalls. “But I didn't want to embarrass myself. I hadn't ridden for over 40 years.”
Then she noticed a session for women and girls at Burgess Park BMX Track in Peckham, south-east London, where Jay-Teale trained. This season Simpson raced at the London BMX series and finished third in her category.
“It was the most worrying experience of my life. But it was also exhilarating,” she says cheerfully. “My son is proud of me. We now share a real love for the sport. It has brought us closer together.”
Since becoming part of the Olympic Games in 2008, the popularity of BMX has risen. A program introduced in London in 2011 by the sports development charity Access Sport has seen tracks built in several London regions, backed up with investment in coaching, and the program is being rolled out to Bristol.
Mavolwane Wright's children Skye,11 and Xander,10 are sponsored riders who have represented Great Britain in every world championship since 2014. Mavolwane Wright says she was motivated to start BMX herself out of an interest aroused by watching so much of it. “It's an eye-opener to share your children's interests,” she explains. “You comprehend what they go through in a much more direct way. It adds another dimension to your relationship.”
It is also a high-impact sport and the risks are fairly obvious. “I totally get the fear,” says Emma Budgens, 51, a BMX exercise coach and cycling instructor. “It's the fear of doing something new, of getting hurt. But I say, ‘Come and give it a try.’ The chance of having an accident is slim, and you can spend time on the flat to improve your confidence.”
1.What can we learn about Pamela Simpson from the first two paragraphs?
A.She tended to be inactive. B.She performed poorly in the race.
C.She used to feel awkward in public. D.She trained at Burgess Park BMX Track.
2.What does the underlined word “exhilarating” in Paragraph 3 mean?
A.Annoying. B.Inspiring.
C.Thrilling. D.Challenging.
3.What benefit did Simpson and Wright get from BMX?
A.More life skills. B.Stronger will.
C.More confidence in themselves. D.Better parent-child relationships.
4.What does Emma Budgens think of BMX?
A.Risky but actually secure. B.Demanding but open to all.
C.Competitive but instructive. D.Pleasant but time-consuming.
