As many as one in five US teenagers have some degree of hearing loss, according to researchers. They say the problem is growing.
“Teenagers really don’t pay attention to how much noise they are exposed to(接触),” Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even very little hearing loss may influence language development,” said Shargorodsky, one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.
“This certainly is big news,” said Alison Grimes, an ear doctor. “Hearing loss is very common in old people,” Grimes said, but she added that it was worrying to see it happen in the younger age group.
In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could influence learning, said Grimes.
The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We know from before that it is difficult to ask this age group about noise exposure – they underestimate it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.
Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

Making Peace with Your Parents

As a teen, you’re going through big changes physically and mentally. Your interests are expanding.  1    

Here is the challenge: Kids need to explore the world in new ways, and parents need to protect them from the dangers that are out in that world. These conflicts （矛盾） can easily set off fireworks in otherwise calm houses. Sometimes conflicts can’t be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents.

For instance, try to find a time to talk when your parents are not angry, tired, distracted, or hungry. A good time to talk is when you’re all relaxed. Timing is everything. If the conversation begins to turn into an argument, you’d better calmly and coolly ask to stop the conversation -- for now. 2  Listen to what your parents are saying, and repeat it back to them. This shows them that you’re listening.3_ 

Respect is the building block of good communication. People who respect each other and care about each others’ feelings can disagree without things getting ugly. _4__ How do you build trust?  Trust comes by actually doing what you say you’re going to do. Some teens find that doing fun activities with their parents can improve their relationships. Sometimes we forget that parents are more than rule-makers—they’re interesting people who like to watch movies, and go shopping—just like their teenagers!

What do you do if you are trying your best, but your relationship with your parents continues to be rocky? _5__ You can find supportive adults, such as a teacher or a coach, who can lend an ear.

Remember you can only change your own behavior; your parents are the only ones who can change theirs. 

A．It also gives them a chance to clear things up if you’re not on the same page.

B．You can pick it up again when everyone’s more relaxed.

C．And then you’ll be able to accept what your parents say.

D．Faced with the challenge, children don’t know what to do.

E. You are more likely to get along with your parents and have more independence if your parents believe in you.

F. And your desire to take control of your own life is growing.

G. You may consider seeking outside help.

B
For a song to become popular, people need to bear it.  In order for people　to hear it, the program directors at radio stations have to play it on the air. A song’s popularity is directly related to how often it is played. That is a big responsibility for program directors. How do they decide what gets played and what doesn’t?
In the past, disc jockeys(音乐节目主持人) decided what music was played on the radio. These DJs had an ear for music and an understanding of what their audience wanted to hear. Today, that is all changing. Most major radio stations are owned by a few large national businesses. The decision of what gets played on the radio is made by executives(主管) who have little or no interest in music. They do, however, know how to run a business, and they know what sells. So, the music industry designs and creates pop entertainers, and executives in the radio industry make sure that their music is played on the radio. This explains why you do not often hear anything new and fresh on the radio. The executives do not want to give air time to music that has not been tested on the market. It is too risky. They prefer to go with music that they already know will sell. They know it will sell because it sold last week and last month and last year. They just have to change it a little.
One of the most criticized(批评) practices in the music industry is the practice of “payola”. This is when record companies pay radio stations to play the music of a given artist. This practice makes many people lose trust in the music industry and is therefore against the law. A radio station can accept money in exchange for air time of a song, but they have to make it clear that the song is being played because its air time was paid for. They cannot present the song as if it were part of the normal play schedule(时刻表).
Payola affects both artists and audiences. The artists who work with small record companies that cannot pay a lot of money to radio stations have a much harder time getting exposure. It creates an unfair playing field. Music lovers suffer because they are not able to hear all the music that is available.
60. According to the passage, most major radio stations belong to       .
A. national businesses                      B. program directors   
C. pop entertainers                         D. record companies
61. “Payola” is the practice of        .
A. artists paying radio stations to play their songs

62. Who can make the largest profits from payola?
A. Disc Jockeys.                               B. The given artists.
C.  Business executives.                        D. Program directors.
63. It can be concluded from the passage that the author        .
A. has a positive attitude towards the practice of “payola”
B. is dissatisfied with the present situation in music industry
C. is calling for a change in the normal play schedule
D. thinks that the radio stations are doing the right thing

Your cell phone holds secrets about you. Besides the names and numbers that you’ve programmed into it, traces of your DNA remain on it, according to a new study.

DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you --- unless you have an identical twin. Scientists today usually analyze DNA in blood, saliva(唾液), or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims.

Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA remained on cell phones --- even when no blood was involved. To find out, she and a colleague collected flip-style(翻盖式) phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user’s ear.  

The scientists scrubbed(meaning “cleaned”) the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated collecting traces on each phone once more. They discovered DNA that belonged to the phone’s owner on each of the phones.

Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were cleaned. That suggests that washing won’t remove all traces of evidence from a criminal’s cell phone. So cell phones can now be added to the list of clues that can help a crime-scene investigation.

1.McFadden decided to find out whether people leave their DNA on their cell phones when she ____ .

2.The scientists allowed the volunteers to keep their cell phones for a week in order to____.

3.The last paragraph mainly tells us that cell phones ____ .
