         Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing
    road accidents to minimum is a must. So, automakers are focused on safety systems more than ever
    before.
    Given the emphasis on improving safety, it's possible that well-known phrases such as "live fast and
    die young" may lose their meaning as innovative (创新的) new devices are built into cars and trucks
    and other things that go.
         Many of the new safety systems that are being added to high-end vehicles are computer-assisted
    technologies that transfer some of the vehicle's operations to the vehicle itself, rather than relying only
    on the driver's decision-making skills.  
         For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking
    when its built-in sensors detect a potential object ahead. The predictive brake assist basically places
    the vehicle's braking system on alert, which helps the system to slow down the car in as little time and
    as short a distance as possible.
         Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects
    based on simple patterns, such as other vehicles vs. a person.
    What's more, built-in "active systems", i.e., predictive precollision (可预测碰撞) systems, will provide
    drivers with advance detection of potential contact between vehicles. These systems compute the
    relative movement of the objects and detect possible dangerous intersections (交点).
         What technological developments have enabled innovations like predictive precollision systems?
    Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure
    communications.
         These communication links allow highways to provide a vehicle's owners with services such as renting
    a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash.  
    Despite these new technologies, drivers cannot take safety for granted.
         Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating
    their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the
    road and your hands on the steering wheel (方向盘).
    1. "Predictive Precollision" can be used to _________. 
    A. detect possible dangerous crossroads
    B. compute the relative movement of the contacting vehicles 
    C. brake the car automatically in as little time as possible
    D. detect potential contacts between vehicles in advance
    2. Which of the following statements is NOT true?
    A. Advanced safety systems make driving an easier job.
    B. Automakers pay more attention to safety system than before.
    C. New advanced technology makes the vehicle operation rely only on the vehicle itself.
    D. Drivers are still expected to drive carefully despite the built-in advanced safety system.
    3. We can conclude that the new technology will _________.
    A. put an end to road accidents
    B. force people to obey traffic laws
    C. see a wide use in the future
    D. ensure the quality of medical care
    4. Which of the following would best serve as the title for the passage?
    A. Live fast, die young
    B. New systems, safer driving
    C. New technology, relaxed drivers
    D. High-end vehicles, big innovation

    第二部分 阅读理解（共25小题。第一节每小题2分，第二节每小题1分；满分45分）

    第一节  阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。

      A new study in West Africa shows how farm irrigation systems powered by the sun can produce more food and money for villagers. The study in Benin found that solar-powered pumps are effective in supplying water, especially during the long dry season.

      Sub-Saharan Africa is the part of the world with the least food security. The United Nations Food and Agriculture Organization estimates that more than one billion of the world’s people faced hunger last year. Around two hundred sixty-five million of them live south of the Sahara Desert. Lack of rainfall is one of their main causes of food shortages.

      Jennifer Burney from Stanford University in California led the study. The research team helped build three solar-powered irrigation systems in northern Benin.

    The solar-powered irrigation systems produced an average of nearly two metric tons of vegetables per month.

      They sold the surplus(过剩的) produce at local markets. The earnings greatly increased their ability to buy food during the dry season which can last six to nine months.

      People in the two villages with the systems were able to eat three to five more serving of vegetables per day. But making the surplus available at markets also had a wider effect.

      The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also increased, though not as much.

      The researchers note that only four percent of the cropland in sub-Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene. And solar power is environmentally friendly.

    1. People living in sub-Saharan Africa are short of food mainly because______.

      A. it seldom rains there throughout the year   B. there is little farmland in the area

      C. people there lack experience in farming    D. people know nothing about irrigation techniques

    2. Which of the following is an advantage of Jennifer’s irrigation systems?

      A. They are not affected by the weather.

    B. They cost much less than traditional irrigation systems.

      C. They have no bad effects on the environment.

      D. They use less fuel than traditional irrigation systems.

    3. We can learn from the last paragraph that______.

      A. people in South Africa will soon be provided with enough food

      B. the demand for fuels like gasoline will greatly decrease in Africa

      C. people in sub-Saharan Africa don’t take agriculture seriously

      D. it’s worthwhile to use the new irrigation systems on the while

    4. People in the two villages owe all the following to Jennifer’s irrigation systems EXCEPT that ______.

      A. they could buy more food during the dry season

      B. they could eat more vegetables than usual every day

      C. they could supply local markets with vegetables

      D. they could provide people in other villages with food

    第三部分  阅读理解（共20小题；每小题2分，满分40分）

        阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

    A new study suggests that the more teenagers watch television, the more likely they are to develop depression （沮丧；抑郁）as young adults.

    The researchers used a national long - term survey of adolescent health to investigate（调查）the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.

        As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one - half hours a day. More than two hours of that was spent watching TV.

        Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty -one.

        The study didn’t explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.

        Previous study found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active to read, to attend religious services and to vote.

    1. The result of the research seems to prove ________.

    A. teenagers are more likely to develop depression than adults

        B. other media uses do no harm to adolescents

        C. TV probably causes teenagers to grow up with depression

        D. those who don’t watch TV will not develop depression

    2. We can learn from the survey that of all the media use ________.

        A. computer games are teenagers’ favorite

        B. most teenagers prefer to listen to the radio

        C. teenagers enjoy watching TV very much

        D. newspaper is not included in the survey

    3. According to the passage, what kind of activity may help prevent depression?

        A. Playing computer games.            B. Taking part in sports.

        C. Listening to the radio.               D. Watching movies.

    4. We can conclude that a teenager should ________.

        A. play more video games instead of watching TV

        B. be active in taking part in outdoor activities

        C. be more active in watching educational TV programmes

        D. attend religious services and care for politics

    第三部分阅读理解 (共15小题；每小题2分，满分30分)

    请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。

    Picking a Christmas tree takes most people a few minutes, a couple of hours if they head to the woods. Dave Murbach needs 11 months.

    Almost every day of every year, Murbach’s thoughts turn to vision of a perfectly shaped evergreen tree that will take everyone’s breath away.

    “The tree,” he says wearily. “Always the tree.”

    Murbach is the man responsible for finding the towering tree that graces Manhattan’s Rockefeller Center each Christmas season.

    “I’m always looking for a tree,” the center’s chief gardener says. “I look for it even when I go to the beach in the summer. It’s like a homework assignment hanging over your head.”

    And if he gets it wrong, there’s nothing hiding it.

    “Every day it’s up, 400,000 people go by, and 2.5 million people watch the lighting celebration on television,” he says.

    This year’s tree, a 74-foot Norway spruce (云杉) from Richfield, Ohio, flown to New York on the world’s largest cargo plane, was lighted on December 2.

    The arrival of the tree leads in the Christmas season in New York - a tradition dating to 1931, when the workers building Rockefeller Centre put up a small tree with decorations.

    The search for the next year’s tree starts soon after the old tree is chopped up for wood chips and horse-jumping logs.

    That’s not as simple as it sounds. Though forests are full of evergreens, few get enough sunlight or space to fill out. And branches in snowy regions often break under the weight, making flees uneven.

    Back at the office, he sorts through hundreds of letters from people offering their trees, many addressed simply to “Mr. Christmas Tree Man.”

    Despite the occasional anxiety attack and sleepless night, Murbach knows the together people you love. That’s what I hope it sets off.”

    But Murbach says he’s always too worn out to celebrate Christmas.

    “No card, no lights, nothing,” he says.

    “No tree?”

    “No tree.”

    1. Murbach takes his job seriously because he most likely wants _____________.

    A. everyone to be happy with his work

    B. to make everyone surprised at his choice

    C. everyone to know his care for their happiness

    D. to attract people’s attention to his special ability

    2. Which is the correct order of the events in the passage?

    a. Murbach’s thoughts turn to a perfectly shaped tree.

    b. 2.5 million people watch the Christmas tree.

    c. The tree is flown to New York.

    d. it was lighted on December 2.

    e. The tree is chopped up.

    f. Murbach searches for the tree.

    A. a, b, c, d, e, f    B. a, f, c, d, b, e            C. c, d, e, b, a, f    D. c, d, b, f, e, a

    3. According to Murbach’s standard of trees, the best tree must _________.

    A. be evergreen                             B. have no space between branches

    C. be thick enough                          D. be equally balanced in shape

    4. Which is tree about Murbach?

    A. He is most devoted to his work.                     B. He is now quite tired of his work.

    C. He has no loved family members.           D. He never wants to celebrate Christmas.

         "I'd be better off dead." he said, without any hesitation. Hearing those words come out of my best
    friend's mouth tore my heart apart. He has repeated that phrase more than once, and my mind
    continually plays it over like a voice recording.
         I met him about three years ago. After knowing me for six months, he told me about his struggles
    with depression. Sadness was not the only feeling that came over me; I was shocked. He seemed so
    outgoing and happy all the time. I soon learned that he was hurt physically and mentally as a young child,
    causing him to have the thought of killing himself.
         He refuses to talk to others about his depression because he now distrusts adults, especially those in
    his family. However, he feels as if I understand him and that I know the right words to speak. Therefore,
    when it comes to helping him, convenience is not in my vocabulary. It does not matter where I am or
    what I am doing, for he always comes first.
         Many students at his school laugh at him when they notice scars on his arms from cutting. As he sees
    it, other kids have every right to make fun of him. But no one holds such a right, so I encourage him to
    ignore the heartless kids who treat him badly. When he feels the weight of judging eyes or hateful voices,
    I always remind him that I care about him unconditionally. Just hearing me say I will always be his best
    friend seems to give him the safety he needs to keep on going.
         My best friend once told me that if he had not had me, he would not be alive. He said that my
    encouraging words helped him not to take his life. Our friendship has taught me that a single kind word
    can influence someone’s life. Life is not easy for every one, which makes me strongly believe in the
    necessity of encouragement.
    1. According to the first paragraph, hearing his friend's words, the author felt______.
    A. puzzled
    B. painful
    C. frightened
    D. hopeless
    2. By saying "convenience is not in my vocabulary", the author means ______.
    A. he is always ready to help his friend
    B. he hardly spares time to help his friend
    C. he has no good excuse for refusing his friend
    D. he is not good at communicating with his friend
    3. The author's friend got into depression mainly because __________.
    A. he lived without his parents
    B. he had poor health
    C. he received little care at school
    D. he had a terrible childhood
