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. 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 |
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. |

About hearing loss, it can be inferred that ________.
| A．the reasons for the rise have been found | B．MP3 players are to blame |
C．listening to loud music may be a cause |
D．noise is the main reason |
The article was written to ______.
| A．warn teenagers that loud music might be harmful |
| B．explain what kinds of noises might affect studies |
| C．suggest that teenagers shouldn’t listen to loud music |
| D．show how important hearing can be for learning |

Liverpool city council (市政厅) want to clear the city of fat pigeons (鸽子). They say that people are feeding the birds, which makes them fat. The pigeons get bigger because they normally eat seeds (种子) and insects (昆虫) for their main food, not high-fat junk food they are eating in the city centre.
The council want people to know that everyone who feeds the pigeons makes the streets crowded (拥挤)with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.
Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds—known as ‘robops’—will sit on the roofs of buildings. They can be moved around to different places. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years. Liverpool city council want to clear the city of fat pigeons because ______.

Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光线) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.
Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts (霜冻) which might come at night and hurt fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed. The huge mirror would ______.

For several days I saw little of Mr. Rochester. In the morning he seemed very busy with business，and in the afternoon gentlemen from the neighborhood called and sometimes stayed to dine with him. When his foot was well enough，he rode out a great deal.
During this time，all my knowledge of him was limited to occasional meetings about the house，when he would sometimes pass me coldly， and sometimes bow and smile. His changes of manner did not offend me，because I saw that I had nothing to do with the cause of them.
One evening，several days later，I was invited to talk to Mr. Rochester after dinner. He was sitting in his armchair，and looked not quite so severe，and much less gloomy. There was a smile on his lips， and his eyes were bright，probably with wine. As I was looking at him，he suddenly turned， and asked me，“Do you think I am handsome，Miss Eyre? ”
The answer somehow slipped from my tongue before I realized it: “No，sir.” “Ah，you really are unusual! You are a quiet， serious little person， but you can be almost rude.” “Sir，I'm sorry. I should have said that beauty doesn't matter，or something like that，” “No，you shouldn't! I see，you criticize my appearance，and then you stab (刺) me in the back! You have honesty and feeling. There are not many girls like you. But perhaps I go too fast. Perhaps you have awful faults to counterbalance (抵消) your few good points.”
I thought to myself that he might have too. He seemed to read my mind，and said quickly，“Yes，you're right. I have plenty of faults. I went the wrong way when I was twenty-one，and have never found the right path again. I might have been very different. I might have been as good as you， and perhaps wiser. I am not a bad man，take my word for it，but I have done wrong. It wasn't my character，but circumstances which were to blame. Why do I tell you all this? Because you're the sort of person people tell their problems and secrets to， because you're sympathetic and give them hope.”
It seemed he had quite a lot to talk to me. He didn't seem to like to finish the talk quickly，as was the case for the first time.
“Don't be afraid of me， Miss. Eyre，”he continued. “You don't relax or laugh very much，perhaps because of the effect Lowood school has had on you. But in time you will be more natural with me，and laugh， and speak freely. You're like a bird in a cage. When you get out of the cage， you'll fly very high. Good night.”At the beginning Miss Eyre's impressions of Mr. Rochester were all except_________.

Since 1950, the amount of information about the nutrition of food has increased by nearly 900 percent. Besides this fact, obesity has risen by 214 percent and nearly two out of every three adults in America are overweight or obese. Being overweight is not only an appearance problem, and it also increases the risk of various diseases including diabetes, sleep disorder and cancer.
With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.
The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.
In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.
According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.
“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.What may cause the risk of diseases according to the text?
