    Identifying young people with the potential to be great athletes has become a serious, business around the world. Many countries, including Australia, have sophisticated(复杂) programs for identifying and nurturing(培养) talent.
    The AIS (Australian Institute of Sport) already runs a program that identifies potential winners starting from the age of 12 based on their physical and physiological(生理的) abilities.
    Could genetics improve these programs? The problem is that no one gene test is ever going to do an accurate job of identifying someone with the physical attributes of a sporting champion, says Professor North.
    "We can think of the elite athlete as what I'd call a complex phenotype(表现型)," she says. “There are going to be a large number of different genes involved. Any one single test is unlikely to be highly predictive.”
    Professor Peter Fricker, director of the AIS, agrees. Although he is intrigued in the possibilities of genetic testing, he says using such tests to identify athletes would be difficult. "The feeling I have is that it won't be that easy," he says. "Talent selection is not just about your genes."
    Since 2004, the AIS has been forbidden by government from any involvement in genetic work, including genetic testing. But Professor Fricker thinks that is likely to change in the near future. "There's been a shift in view more recently," he says.
    When it does, the AIS will resume its work on the genetics of sports performance, Professor Fricker says. They would be particularly interested in looking for more genes that might help shape elite performance, but also for genes that increase the risk of injury.
    Last year, the Human Genetics Society of Australasia issued a position statement on gene testing for sport, after concerns that people could use tests to steer children into particular sports.
    “The Human Genetics Society thinks there are not enough data to use these tests for determining what sport kids should do,” said Professor David Thorburn, president of the society.
    He stressed that genetic tests should not be performed on children, except in very specific medical circumstances.
    57．The aim of the AIS’s program is to        .
    A．predict how genes are connected with injuries
    B．find potential great athletes
    C．find out what qualities a professor has through gene tests
    D．turn an athlete into a champion by transferring genes
    58．By saying “Talent selection is not just about your genes”, Fricker means         .
    A．effort is more important than genes in most cases
    B．you can’t choose an athlete just depending on genes
    C．to research one’s genes takes a long time
    D．most people don’t believe in genetic tests
    59．The underlined word “resume” in Para. 7 can be replaced by              .
    A．stop B．complete   C．reduce      D．continue.
    60．What’s Professor David Thorburn’s attitude towards genetic tests?
    A．Genetic tests have a negative effect on children.
    B．Genetic tests, under certain conditions, can be conducted on children.
    C．Genetic tests can reduce the risk of athletes’ injuries.
    D．People could use genetic tests to decide what sport kids should take.

    Need more evidence that London is a serious coffee town? Mr. Davies is actually England’s third consecutive world barista champion. The first was James Hoffmann, who started Square Mile Coffee Roasters squaremilecoffee.com) in 2008 .It’s a small operation, recently relocated to an arched vault under some train tracks in East London.
    Today, Square Mile’s black bags of beans have become shorthand for quality. They supply beans to Moon Bar (3 Bateman Street; 44-20-7287-4796), just opened by the same team behind Flat White (17 Berwick Street; 44-20-7734-0370; flat-white.co.uk).
    Though it’s recently been co-opted(增加的) by chain stores, the “flat white” is also a symbol of serious coffee: it’s basically a cappuccino-size style— flat and white — a style imported from Australia (some say New Zealand) when a wave of baristas emigrated from those countries. (Australians and New Zealanders are to espresso what Russians are to chess: they’re just better at it.)
    Still, independent stores continue to appear in all corners of the city. Last year, the Espresso Room (31 Great Ormond Street; 44-20-7932-137-380; theespressoroom.com) opened in a truly tiny storefront. Yet the owner Ben Townsend manages to fit a Marzocco espresso machine, some benches and a case with pastries.
    And farther north in Islington, a bar called Tina, We Salute You (47 King Henry’s Walk; 44-20-3119-0047; tinawesaluteyou.com) opened last February. (According to the owners, the name comes from a daily greeting they give to a cheesecake portrait of a curvy subject named Tina.)
    45. How many bars are mentioned in the text?
    A. 4        B. 5.       C. 6      D. 7
    46. We can read in the passage that Square Mile Coffee Roasters is well-known for its________.
    A. milk    B. chess   C. beans   D. fruit
    47. According to the text, we know that________.
    A.UK is home to the flat-white.
    B. the flat-white is exported from Australia.
    C. chess is popular in Russia.
    D. you can find the flat-white only in the chain stores.
    48. The writer wrote this passage in order to tell us________.
    A. the meaning of   “flat white”.         B. London is famous for its history.
    C. the number of coffee bars in London    D. London is famous for its coffee bar.

    　　In ancient Japan, if you saved someone’s life, they would make it their duty to spend the rest of their life serving you. Nowadays, if you rescue someone’s story, he or she will feel the same kind of gratitude (感激).
    　　It happens all the time. Someone in a group is telling a story and, just before their big point, BOOM! There’s an interruption. Someone new joins the group, a waiter with a plate of biscuits comes over, or a baby starts crying. Suddenly everyone’s attention turns to the new arrival, the food on the plate, or the “charming” little child. Nobody is aware of the interruption — except the speaker. They forget all about the fact that the speaker hasn’t made his or her point.
    　　Or you’re all sitting around the living room and someone is telling a joke. Suddenly, just before their big punch line (妙语), little Johnny drops a dish or the phone rings. After the crash, everyone talks about little Johnny’s carelessness. After the call, the subject turns to the upcoming marriage or medical operation of the caller. Nobody remembers the great punch line got unfinished — except the joke teller. When it’s you entertaining everyone at a restaurant, have you ever noticed how you can almost set your clock by the waiter coming to take everyone’s order just before your funny punch line?
    　　Most joke and story tellers are too shy to say, after the interruption, “Now, as I was saying …” Instead, they’ll spend the rest of the evening feeling bad they didn’t get to finish. Here’s where you come in. Rescue them with the technique I call “Lend a Helping Tongue.”
    　　Watch the gratitude in the storyteller’s eyes as he stabilizes where his story sunk and he sails off again toward the center of attention. His expression and the appreciation of your consideration by the rest of the group are often reward enough. You are even more fortunate if you can rescue the story of someone who can hire you, promote you, buy from you, or otherwise lift your life. Big winners have excellent memories. When you do them subtle favors like Lend a Helping Tongue, they find a way to pay you back.
    　　53. Very often, a storyteller cannot make his point because _________.
    　　A. people are more interested in food than his story
    　　B. many guests bring their babies to the party
    　　C. he is interrupted by something unexpected
    　　D. his story is easily forgotten by the listeners
    　　54. From Paragraph 3, we know that when someone is telling a joke, _________.
    　　A. something bad will surely happen just before their punch line
    　　B. listeners’ attention is often drawn to something else
    　　C. the only person really interested in the joke is the joke teller
    　　D. the waiter knows when to take everyone’s order
    　　55. How can we help the joke and story tellers when they are interrupted?
    　　A. By giving them a chance to finish.
    　　B. By comforting them to make them happy.
    　　C. By going on telling the story for them.
    　　D. By teaching them some useful techniques.
    　　56. What is the text mainly about?
    　　A. People should learn how to take turns in a conversation.
    　　B. We can win someone’s heart by getting him back to his story.
    　　C. Telling jokes will make you the center of attention.
    　　D. It is impolite to cut in on someone’s talk.

    WHAT can help you make a fortune in the future? Graduating from a top university might not be enough．A new study from the University of Essex in Britain has shown that the more friends you have in school, the more money you’ll earn later．
    The idea that popularity could have a serious impact on one’s earning potential shouldn’t come as too much of a surprise．The researchers noted that if you want to get_ahead in life, social skills and networking are easily as powerful as talent and hard work．
    “If a person has lots of friends, he or she has the ability to get along with others in all kinds of different situations,” said Xu Yan, 17, from Nantou High School in Shenzhen, who totally agreed with the recent finding．“Also, friends always help each other．They not only create wider social circles for you but lift your mood when you occasionally feel depressed．” She believed that all this helps you “earn a higher salary”．
    Maybe that’s why some people think the younger generations are in the age of Friendalholism （交友狂症）．A woman even complained that the networking website Facebook’s 5000-friend limit was too low for her large reserve of social contacts．
    But Meghan Daum, who works with The Los Angeles Times in the US, disliked the idea that quantity trumps （胜过） quality in the age of Friendaholism．“Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom I enjoy actually seeing．” said Daum．She admitted that some Internet social networkers just want to get as many of not-really-friends as possible．Although she agreed that social ties grease （润滑） the wheels of life, she also warned, “Finding a real friend is something that really matters．”
    63．What CANNOT be learned about friends from the passage?
    A．They enlarge social circles for you．
    B．They offer encouragement when you are upset．
    C．Only talented friends help you to earn success．
    D．Friends enable you to overcome difficulties．
    64．In the age of Friendalholism, ________．
    A．there are networking websites to help people make friends
    B．a person with popularity is sure to enter a top university
    C．facebook helps social networkers make as many friends as possible
    D．there are always more not-really-friends than actual ones
    65．The underlined words probably mean ________．
    A．expect      B．struggle    C．graduate   D．succeed
    66．Meghan Daum holds the attitude towards making friends that ________．
    A．actual friends outweigh not-really-friends
    B．the more friends one has, the better
    C．friends can help make a big fortune
    D．social relations can hardly make one’s life better

    Having reached the highest point of our route according to plan, we discovered something the map had not told us. It was impossible to climb down into the Kingo valley. The river lay deep between mountain sides that were almost vertical（垂直）.We couldn’t find any animal tracks, which usually show the best way across country, and the slopes were covered so thickly with bushes that we could not see the nature of the ground. We had somehow to break through to the river which would give us our direction out of the mountains into the inhabited lowlands.
    Our guide cut a narrow path through the bushes with his long knife and we followed in single file. Progress was slow. Then, when we thought we had really reached the river, we found ourselves instead on the edge of a cliff with a straight drop of 1,000 feet to the water below. We climbed back up the slope and began to look for another way down. We climbed slipped, sweated and scratched our hands to pieces and finally arrived at the river. Happily we came downhill along its bank without having to cut our way. However, after a few miles the river entered a steep-sided gap between rocks and suddenly dropped thirty-five feet over a waterfall. There was no path alongside it and no way round it.
    Then one of the guides saw a way of overcoming the difficulty. There was a fallen tree lying upside down over the waterfall with its leafy top resting on the opposite bank below the falls. Without hesitation he climbed down the slippery trunk to show us how easy it was. Having got to the fork of the tree, he moved hand over hand along a branch for four or five feet with his legs hanging in space, then he dropped onto the flat bank the other side, throwing his arms in the air like a footballer who has scored goal, and cheerfully waving us on.
    74．Having reached the highest point on their route, the travelers expected to be able to    .
    A．track animals to the river
    B．put away the maps they had been using
    C．come near to the river from a different direction
    D．get down to the river without much difficulty.
    75．The travelers wanted to get to the river because      .
    A．it would lead them to the waterfall
    B．it would show them which way to go
    C．it was the only possible way out of the mountains
    D．it was a quicker way than going over the mountains
    76．One reason why the travelers took so long to get to the river was that      .
    A．it was too hot to move quickly
    B．there was no proper path
    C．they all tried to go different ways
    D．they could not follow the animal tracks
    77．To get past the waterfall the guide had to      .
    A．use a fallen tree as a kind of bridge
    B．cross the river above the waterfall
    C．slide down a steep river bank
    D．swing across the river from a high branch

    B
    People have always had to find ways to keep food safe to eat. Methods to dry, smoke and salt food were invented thousands of years ago. The process of canning is much more recent. This storage method keeps food safe to eat for long periods of time. Today, canning is one of the most popular methods of storing food.
    Canning uses heat to kill bacteria and other micro-organisms that cause poisons to form in food. Canning also takes away the air that these organisms need to live. One popular method of canning uses a water bath.
    Clean fruits or vegetables are placed in glass bottles. The food can be put into the bottles either hot or cold. The cold method is used for soft fruits and vegetables that could lose their shape or taste. Firmer fruits and most vegetables are usually cooked. They take up less space in the bottles. After the food has been placed in glass bottles, boiling water is poured into the bottles to about three centimeters below the top. Then covers are placed on the bottles, but are not turned all the way. The bottles are placed in a large container filled with warm water that is then brought to a boil. The water must completely cover the bottles, from three to five centimeters over the top. When the water boils, any air in the bottles will be expelled. The boiling continues for several minutes. Then the bottles are allowed to cool. Finally, they are placed briefly into cold water. This makes a strong barrier to keep the air out. In other words, a vacuum is created. When the bottles are completely cool, notes can be placed on them to identify what is inside. The bottles can then be stored in a cool, dark place at a temperature of between four and twenty-one degrees Celsius.
    Canning allows your family to enjoy foods that might not come fresh throughout the year. It is also a good way to store food for six months to a year, or even several years, in case of an emergency. It does not cost much to continue canning every year once the equipment has been purchased.
    You can get more information about canning food from the group, Volunteers in Technical Assistance. VITA is on the Internet at vita.org.
    55. Which of the following is the right order of canning food?
    a. put bottles in warm water.          b. place notes on the bottles.
    c. place bottles briefly into cold water  d. pour boiling water into bottles
    A. d a c b   B. a b c d    C. b d c a   D. a d c b
    56. According to the text, which of the following is right?
    A. The way to can food has been found by ancient Chinese.
    B. Canning uses water to kill bacteria.
    C. Hard fruits are suitable for cold method.
    D. The boiling water will take away the air in the bottle.
    57. What does the word “vacuum” mean in the – paragraph?
    A. a missing situation   B. a gap   C. an enclosed space without air  D. a hole
    58. what’s the best title of the text?
    A. The advantages of canning food.
    B. Canning food and health.
    C. Put fruits and vegetables into cans.
    D. How to make canning food.
