    Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mice's genes are so similar to humans', their findings could lead to the treatment of more genetic diseases.

    Scientists at the University of California, Davis studied information from a data bank of mice's genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.

    Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.

    "This is extremely valuable for people with hereditary eye disease," said researcher Professor Ala Moshiri. "All researchers are going to start using these data. In the past, we knew the problem was there but we didn't know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable." Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby's parents!

    Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice's genes to those of patients.

(1)、How many hereditary-sight-loss-related genes were newly found?
A、86. B、261. C、300. D、347.
(2)、Why is the percentage of genetic eye problems mentioned in paragraph 3?
A、To show the significance of studying mice's genes. B、To prove mice's genes are similar to humans'. C、To warn the high risk level of suffering them. D、To explain how common they are among people.
(3)、What should scientists do first to unlock secrets of genetic blindness?
A、Compare humans' genes with mice's. B、Recognize each gene's role of humans. C、Set apart a gene of a mouse each time. D、Figure out each gene's function of a mouse.
(4)、What can be a suitable title for the text?
A、New Ways to Cure Sight Loss B、Genes Found Behind Eye Problems C、Genetic Diseases Discovered in Mice D、Humans Genes Causing Eye Diseases

    After spending the first five years of his life in San Diego, Adam Driver's family packet up and moved to a small town in Indiana, where Adam enjoyed a relatively routine adolescence. Then the horrific events of September 11th made Adam's life become anything but routine.

    Just a few months following the events, Driver decided to join the United States Marine Corps. He considered 9/11 as being one of the reasons for joining the army, with his desire to leave Indiana providing the rest. He once said,"I'm grateful for having grown up in Indiana, but I needed to go out and the Marine Corps was a nice, stable option." After serving for two and a half years, and just two months before he was sent to Iraq, Driver injured his sternum in a biking accident. After he was healed, he injured it again during military training, which resulted in an honorable medical discharge.

    After leaving the military, Driver decided to try his hand at acting. At first he studied close to home at the University of Indianapolis, but after just a year, he transferred to Julliard in New York City. He lived in a tiny apartment in Hoboken, New Jersey apartment while studying drama at a prestigious performing arts conservatory(音乐学院). Following his graduation in 2009, Driver immediately began appearing in plays, including 2010's Mrs. Warren's Profession.

    Adam's first major television experience was a guest spot on Law & Order, and was soon followed by a small role in the award-winning film You Don't Know Jack, which was Driver's first experience working with Home Box Office. Then after landing his star-making role on Girls, Driver was cast in a handful of feature films, including 2011's J. Edgar and 2012's Gayby, Not Waving but Drowning and Frances Ha.

    He'll appear next year in the Coen brother's Inside Llewyn Davis and Steven Spielberg's Lincoln.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity?Do some kinds of personalities lead to longer lives?A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing,more active and less neurotic (神经质的) than other people.Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span.These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer.Those who were more self-disciplined,for instance,were no more likely to live to be very old.Also,being open to new ideas had no relationship to long life,which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate.But the new paper suggests that if you want long life,you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity.That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets.Patterns of childhood eating can be hard to break when we're adults,which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny(命运),and everyone knows that individuals can learn to change.But both studies show that long life isn't just a matter of your physical health but of your mental health.

    Winter solstice(冬至), an important solar term in the traditional Chinese calendar, as the name implies, means the coming of winter. It generally occurs between December 21st and 23rd. According to the traditional Chinese calendar, one year is divided into twenty-four solar terms. On this day, in the Northern Hemisphere the period of daytime is the shortest of the year and the period of night is the longest.

    In Northern China there is a custom of eating dumplings during winter solstice. The tradition of eating dumplings during winter solstice has its origin in early times. It is said that dumplings were invented by Zhang Zhongjing, a well-known doctor from the Eastern-Han Dynasty.

    One winter, he noticed that many people's ears were frozen, which made him sad. In order to prevent and cure the freezing injury caused by the cold, he asked his followers to boil mutton, chilies and other ingredients with medicinal properties in a pot for fending off cold. After these were boiled, they ladled(舀取) the mutton and other ingredients out of the pot, cut them into pieces, and then wrapped them with dough skins in the shape of ears. Afterward, they put these into pots to boil again.

    On the day of the winter solstice, the people whose ears were frozen were sent to eat the dumplings. People who ate it felt warm from head to toe and had their cold injury healed. Thereafter, every winter solstice people ate dumplings. Then there became a saying that if you eat dumplings during the winter solstice, then you won't freeze your ears off.

    Afterwards, Zhang Zhongjing died on the day of winter solstice. In order to honor him, every year on the day of the winter solstice every household makes dumplings.

    London's newest skyscraper(摩天大楼)is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 meters, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better.

    The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire(尖顶). The sides of the building aren't regular. So the building has an unusual shape. And that is how the building got the name:the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts(桅杆)of the ships that were once on the river Thames.

    The Shard has 87 floors. At the moment the building is empty, but finally there will be a five-star hotel. There will also be top quality restaurants, apartments and offices.

    Before building work began, a lot of people didn't want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians(埃及人)did that 4, 500 years ago.

    Other critics don't like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive apartments and stay in the hotel. But the people living near the Shard are among the poorest in London. So the Shard seems a symbol of the division(分化)in society between the very rich and the poor.

    The Shard now dominates the London skyline. It is not certain, however, that ordinary London citizens will ever accept it as a valuable addition to the city.

    Tokyo is one of those places that you can love and hate at the same time.

    In Tokyo there are always too many people in the places where I want to be. Of course there are too many cars. The Japanese drive very fast, but in Tokyo they often spend a long time in traffic jams. Tokyo is not different from London, Paris and New York in that. It is different when one wants to walk.

    At certain times of the day there are a lot of people on foot in London's Oxford Street. But the streets near the Ginze in Tokyo always have a lot of people on foot, and sometimes it is really difficult to walk. People are very polite; there are just too many of them.

    The worst time to be in the street is at 11:30 at night. That is when the nightclubs are closing and everybody wants to go home. There are 35,000 nightclubs in Tokyo, and you do not often see one that is empty.

    During the day,most people travel to and from work by train. Tokyo people buy six million train tickets every day. At most stations, trains arrive every two or three minutes, but at certain hours there do not seem to be enough trains. Although they are usually crowded, Japanese trains are very good. They always leave and arrive on time. On a London train you would see everybody reading a newspaper. In Tokyo trains everybody in a seat seems to be asleep, whether his journey is long or short.

    In Tokyo, I stood outside the station for five minutes. Three fire-engines raced past on the way to one of the many fires that Tokyo has every day. Tokyo has so many surprises that none of them can really surprise me now.
