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.The writer advises teenagers __________.
A.to turn the sound down |

Taking exams in a large group setting can be stressful for students and for the staff members who are watching over them. When classrooms are crowded and desks are close together, cheating might be tempting.
One university in Thailand came up with an anti-cheating hat that makes it almost impossible for students to see other students’ papers. A photo of the students wearing the anti-cheating hats made its way to the internet, and the university was criticized for making students wear those ridiculous looking homemade hats. The hats were made by stapling two pieces of paper onto a headband, one to each side of the head.
After being criticized, senior academic staff at Kasetsart University in Bangkok, Thailand, released a statement saying that the hats idea came from students. They said that in a bid to prevent cheating they asked the students for ideas on how to prevent cheating in the upcoming exam, which was being taken by almost one hundred students. Students came up with different ideas, then the paper hat idea was selected by them as the most fit. The university claims that no-one was forced to use the hat, but they all chose to do so. “When wearing the hat during the exam, students felt more relaxed,” Nattadon Rungruangkitkrai, a lecturer at the university said.“It was not meant to indicate that Kasetsart students often cheat on exams. I apologize if the photo makes other people look at my students in a negative way,’ Rungruangkitkrai added.Why was the university criticized on the Internet?
A.The homemade anti-cheating hat looked too simple. |
B.Wearing the anti-cheating hat made students look ridiculous. |
C.Wearing the anti-cheating hats couldn’t prevent students from cheating in the exam. |
D.The university forced students to wear the anti-cheating hat. |
What’s most of the Kasetsart University students’ attitude towards the cheating hat?
A.skeptical | B.supportive | C.objective | D.negative |
It can be inferred from the passage that_______.
A.It’s useless wearing the anti-cheating hat in the exam. |
B.Kasetsart students are often caught cheating in the exam. |
C.Wearing the anti-cheating hat is effective in some degree. |
D.Some students are forced to wear the anti-cheating hat. |
There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved.
I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.
It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive; I decided to wave back.
From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.
The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug. I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.
I looked forward to the return journey.The author expected the train trip to be _________.

Narayana Hrudayalaya, a complex of health centers based in southern India, offers low-cost, high-quality specialty care in a largely poor country of 1.2 billion people. By thinking differently about everything from the unusually high number of patients it treats to the millions for whom it provides insurance, the hospital group is able to continually reduce costs. Narayana Hrudayalaya’s operations include the world’s largest and most productive cardiac (心脏病的) hospital, where the average open-heart surgery runs less than $2,000, a third or less what it costs elsewhere in India.
Narayana Hrudayalaya’s origins date back to 2001, when it built its massive cardiac center on the outskirts (市郊)of Bangalore. But it has expanded since then into what founder Dr. Devi Shetty calls a “health city”, a series of centers specializing in eye, trauma(创伤), and cancer care, Narayana Hrudayalaya now manages or owns hospitals in 14 other Indian cities.
Expanding access is paired with a ongoing focus on efficiency. Typically, says Shetty, private hospitals in India focus on patients who can easily afford treatment. “We did it the other way around,” he says. “This hospital is for poor people, but we also treat some rich people. We don’t look at people who are shabbily dressed and have trouble paying as outsiders.” Narayana Hrudayalaya’s flagship hospital has 3,000 beds and negotiates for better prices and buys directly from manufacturers, cutting out distributors(分销商).
In addition to cost-cutting, Narayana Hrudayalaya finds creative ways to make the economics work. The company started a micro-insurance program backed by the government that enables 3 million farmers to have coverage for as little as 22 cents a month in premiums(保险费). Patients who pay discounted rates are in effect compensated by those who pay full price
Doing something—doing more, actually—is the point. By 2017, Shetty, 58, plans to expand from 5,000 beds throughout India to 30,000. Before becoming one of India’s best-known health-care entrepreneurs, Shetty was its best-known heart surgeon. He was interrupted in surgery one day during the 1990s by a request to make a house call. “I said, ‘I don’t make home visits,’ ” Shetty says, “and the caller said, ‘If you see this patient, the experience may transform your life.’”The request was from Mother Teresa. Inspired by her work with the poor, he then set out to create a hospital to deliver care based on need, not wealth. “One lesson she taught me,” he says, quoting a saying he keeps framed in his office, “is ‘Hands that sew are holier than lips that pray.’”Narayana Hrudayalaya started a micro-insurance to _______.
A.cut down on the cost of the treatment |
B.get the support of the government |
C.make the company run smoothly |
D.attract more people to its hospital |
We can infer from the passage that _______.
A.the cost of medicine care in India is very low |
B.Shetty wouldn’t have succeeded without Mother Teresa |
C.Shetty and his colleagues are likely to make home visits now |
D.Shetty has expanded his hospitals to most of other cities in India |
Why did Shetty build the massive cardiac center in 2001?
A.He wanted to build a health city. |
B.He was motivated and decided to help more people. |
C.He intended to develop his career in different areas. |
D.He meant to help more poor people get free treatment. |
How would you understand the underlined sentence in the last paragraph ?
A.It’s doing something and doing more that really matters. |
B.It’s not easy to take positive action to contribute to society. |
C.Healthcare workers are the holiest persons in the world. |
D.Praying alone is of no significance in face of difficult situation. |
American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists (神经学家)and psychologists from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day—over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal(能发出声音或语言的) than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic(超声波的) range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups幼崽were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
“Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals.”From the second paragraph, we can learn that ________.
A.women always speak more words than men |
B.men and male rats have low levels of language protein |
C.women and male rats have similar levels of Foxp2 |
D.McCarthy isn’t the first to find females more talkative |
The underlined phrase “fussed over” in the third paragraph probably means______.
A.paid attention to | B.related to | C.put pressure on | D.counted on |
The researchers carried out the experiments on rats in order to _______.
A.test which part of the brain is key to language in rats and humans |
B.prove the levels of Foxp2 protein in humans and rats are different |
C.determine the reason why female rats are more talkative than male rats |
D.discover the association between Foxp2protein and vocal communication |
Which of the following can be the best title for the passage ?
A.Tests on humans and rats | B.Why women are the talkative sex |
C.Sex differences in fussed over | D.Foxp2 protein determines oral ability |
