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 (暴露) to, Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even slight hearing loss may affect 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 affect 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 knew from before that it is difficult to ask this age group about noise exposure – they underestimate (低估) 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.
1.According to the researchers, in a US class of 40 students, about ____ students have some degree of hearing loss.
A. one B. five C. six D. eight
2.Which of the following statements is true according to the article?
A. Slight hearing loss does not influence learning.
B. Only a few old people have hearing problems.
C. Hearing problems can slow language development.
D. Noise exposure is clearly noticed by teenagers.

In modem times, many teenagers have idols of their own who are always some stars on TV on the Internet, etc. These stars always think that a slimmer figure may be perfect for themselves. However, does size really matter? Are teenage fans trying hard to become like their idols? Do famous stars really have the power to influence people especially teenagers?
For the longest time, many parents blame (责备) teen idols for influencing the way their kids act. Have you noticed how teens idolize the stars these days? Even, their personal affairs are being followed by kids these days. Take for example the case of Lindsay Lohan or Mary Kate Ashley, They are definitely famous teen stars.

It is a fact that the media and especially famous teen stars can influence people powerfully. But teenagers are easily influenced because teenage years are the period when our personality and identity developments take place. Teens watching TV shows and reading magazines are easily pulled into the dieting and harmful eating habits because the media have some ways to pull these acts. They use thin models and stars to endorse (宣传) products or to star in an up-and-coming shows or movies. With fierce competition, stars are forced to eat less and do extreme exercise routines to get the roles or offers that come their way.
Living in today’s time and generation is a bit disturbing to a lot of parents. Media, especially as well as the stars, have a very powerful influence to drive teenagers to good or bad. It’s good that we can control ourselves to avoid bad things from happening. If not, parents should really be aware and guide their teens to determine what’s in and what’s out.

Teenagers who spend hours in front of the television may have a poorer diet as young adults.
A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?
On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.
On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.
Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who’d watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.
As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.
1.What’s the best title for this passage?
A. Teenagers’ TV Time May Affect Their Diets Later
B. People Should Keep Away from TV to Keep Healthy
C. Why Do Teenagers Like TV?
D. Parents’ Own Habits May Affect Children Later
2.What suggestion does the author give the parents?
A. They can’t do what they don’t want their children to do.
B. They must watch TV with their children.
C. They should forbid the children to watch TV.
D. They should pay attention to nutrition in diets.

A. adding B. stopping
C. controlling D. checking
4.According to the passage, heavy TV viewers tend to _________.
A. eat more fruits B. take in fewer vegetables

Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants (移植). However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects (排斥) the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel’s Tel Aviv University printed a 3D human heart on April 15.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” professor Tal Dvir told CNN.
Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels (血管), chambers (心室) and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb (拇指). And, although it can contract (收缩) like a muscle, it cannot pump out blood like a real one. At present, the heart prototype (样品) is like a tiny airplane that has all of the right parts, but can’t fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue (脂肪组织) into human heart tissue with stem cell (干细胞) technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.
“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized (个性化的) for every patient.”
But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice.
“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely,” Dvir said.
1.Why is the 3D-printed heart important?
A.It will be used on a patient.
B.It is the first 3D-printed heart.
C.It will replace a heart donation.
D.It has a complete heart structure.
2.What problem do 3D-printed hearts have?
A.They cost too much. B.They are too small.
C.They can’t contract. D.They are hard to produce.
3.Why would there be less risk of organ rejection with the 3D-printed heart?
A.It would be made with stem cell technology.
B.It would be made from human fat tissue.
C.It would come from a patient’s body.
D.It would be printed according to the patient’s condition.
4.What attitude does Tal Dvir hold toward the future of 3D printing of organs?
A.Confident. B.Doubtful.
C.Worried. D.Confused.

It was one of my first lessons as an international student in New York City. My US history teacher had just finished his lesson. He sat back in his armchair comfortably, and asked: “Was there anybody doing anything interesting yesterday?”
“I drew a panda, which was lovely!” a girl beside me shouted.Then, the talk developed rapidly. Someone said he had received his learner’s driving permit, while another mentioned that she had spent the first salary from her part-time job. Everybody seemed to have something to say. Although there was a range of people, from different backgrounds, people seemed to feel at home with each other.
Not me. I stayed aloof from the discussion. I looked through my notes until I looked up to see another teacher come in and share some cookies he had made yesterday. The beautifully baked cookies sent out a good smell, which made it impossible to concentrate on my work any longer. However, my seat was in the back row, and I was too shy to stand up and take a cookie for myself.
“Go ahead and have one!” It was the history teacher: “If you don’t stand up, nobody is going to feed you!”
I was still hesitant, but I got up and took a cookie with some other classmates. Now I felt more at ease. We laughed about how “greedy” we were.
The “cookie crisis” had taught me a lesson. I would have to be less shy in the United States. Here was a mixed and various culture, and if I wanted to get anywhere I would have to brave its newness and difference and make myself heard, just as the teacher had said. Otherwise, “Nobody is going to feed you.” It was something a person new to the US, such as myself, needed to learn.

A. lively B. lonely
C. bad D. quiet
2.What does the underlined phrase “aloof from” mean?

3.What prevented the writer from getting a cookie for himself at first?

C. His strangeness. D. His weakness.

Protecting wildlife has become a tough problem in today’s world. As one of the effort, many countries formulate(制定) related laws to protect wildlife. The need for such protection was realized centuries ago in India.
About 300 BC an India writer described forests that were somewhat like national parks today. The game of killing animals was carefully controlled. Some animals that became dangerous to human visitors were trapped or killed outside the park.
The need for wildlife protection is greater now than ever before. About a thousand kinds of animals are in danger of extinction(灭绝), and the speed at which they are being destroyed has been increasing. With mammals(哺乳动物), for example, the speed of extinction is now about one kind every year. From AD 1 to 1800, the speed was about one kind every fifty years. Everywhere, men are trying to solve the problem of saving wildlife while caring for the world’s growing population(人口).
