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.

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

Born in September, 1987, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.

Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备） to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgrum. Her services were recognised in the form of a Military’s Medal by the French government.

In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.

There are thousands of things to be sold that are of all colors and shapes in a supermarket, making you believe that they are good enough for you to have a try. How packaging(包装)is the quiet but persuading salesman?  

There on the shelves，each bottle, can and box has been carefully designed to speak to the inner self of the consumer(消费者), so that he is buying not only a product but also his belief in life. Scientists have studied on this and found that the look of the package has a great influence on the “quality” of the product and on how well it sells, because “Consumers generally cannot tell between a product and its package. Many products are packages and many packages are products,” as Louis Cheskin, the first social scientist studying consumers’ feeling for packaging, noticed.

Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years，the bright red color of tomatoes and carrots on the thin bottle makes you feel that it’s very good for your body. And the word “green" today can keep food prices going up.

Shapes are another attraction．Circles often mean happiness, because they are pleasing to both the eye and the heart. That’s why the round yellow M sings of McDonald’s are inviting to both young and old.www.7caiedu.cn

This new consumer response(反应)to the colors and shapes of packages reminds(提醒)producers and sellers that people buy to meet the needs of both body and heart.

1.According to the passage, ______ seems to be able to persuade a consumer to buy the  product.

If the rose can be said to be a special flower, then the apple can be said to be a special fruit. It is very important in American culture. American stories speak of Johnny Appleseed, who went throughout America collecting apple seeds and planting apple trees. He had a great love for nature and went through fields and farms adding richness and beauty to the country.

One of the first sayings taught to school children is, "An apple a day keeps the doctor away." This short saying encourages children to eat fresh fruit to keep healthy. If someone always says good words to a person, people will call him an "apple polisher". This, however, is not a good name. If someone is very dear to us, we say that he or she is the "apple of our eye".

Most people believe that the fruit which Eve gave to Adam was an apple, even though the Bible(圣经) never says so. The apple, therefore, is a deep part of the language and stories of America.

An apple is also delicious. Apples can be cooked in many ways, used as a dessert (甜点) , and made into sweet juice.

In many parts of the country during the harvest season, a popular activity is to go into an apple garden to pick apples. Washington, D. C. and New York are both famous for their apples.

Finally, when it’s time to take a vacation to American cities, one can always visit New York, which is "the biggest apple" of all the American cities.

I will never forget the year I was about twelve years old. My mother told us that we would not be _36_ Christmas gifts because there was not enough money. I felt sad and thought, “What would I say when the other kids asked what I’d  37 ?” Just when I started to  38 that there would not be a Christmas that year, three women  39 at our house with gifts for all of us. For me they brought a doll. I felt such a sense of  40  that I would no longer have to be embarrassed when I returned to school. I wasn’t  41 . Somebody had thought  42 of me to bring me a gift. 

Years later, when I stood in the kitchen of my new house, thinking how I wanted to make my  43 Christmas there special and memorable, I  44  remembered the women’s visit. I decided that I wanted to create that same feeling of 45  for as many children as I could possibly reach.

So I  46  a plan and gathered forty people from my company to help. We gathered about 125 orphans (孤儿) at the Christmas party. For every child, we wrapped colorful packages filled with toys, clothes, and school supplies,  47 with a child’s name. We wanted all of them to know they were  48 . Before I called out their names and handed them their gifts, I   49  them that they couldn’t open their presents  50  every child had come forward. Finally the  51  they had been waiting for came as I called out, “One, two, three. Open your presents!” As the children opened their packages, their faces beamed and their bright smiles  52 up the room. The  53  in the room was obvious, and  54  wasn’t just about toys. It was a feeling –the feeling I knew  55  that Christmas so long ago when the women came to visit. I wasn’t forgotten. Somebody thought of me. I matter.
