    B
    As a teenager of the digital era, it is really hard to say no to fantastic electronic gadgets(电子产品). Many of us can’t get through a day without using our mobile phones or checking our e-mails. No matter if we’re “@home”, “@school” or“@play”, living without technological toys seems more and more unthinkable.
    However, although gadgets bring convenience, many of us can start to feel stressed out by them. And, a lot of electronics are fairly expensive. Fashionable gadgets come and go in the digital age in the blink of any eye. So, think twice before you pulling out your wallet.
    Here are some of the most popular gadgets and their pros and cons:
    Pros: Laptops have made our lives much easier. You can take your books, movies, music and homework everywhere.
    Cons: They cost at least 4,000 yuan! If you only want to share photos or games with your friend, then a flash memory stick is a great cheap alternative.
    Pros: As well as carrying your favourite music, a video MP3 player can play up to 150 hours of movies and TV programmes.
    Cons: The price—sometimes more than 2,000 yuan—is the first concern. Secondly, though music is really important to young people, ask yourself if video is really necessary. A regular MP3 player is a lot cheaper. And remember, don’t let the loud volume damage your hearing.
    Pros: New mobile phones combine traditional functions with a digital camera, MP3 player and even a radio. Some can also send and receive e-mails.
    Cons: Always trying to keep up with the latest model can be a waste of money. There are always new, improved phones coming out. Don’t be a fool. Do you really need all these functions? Think twice before you buy.  
    60. According to the writer, which of the following statements is true?
    A. Teenagers can’t live through a day without fantastic electronic gadgets.
    B. Teenagers can hardly live happily without electronic gadgets.
    C. Teenagers’ life is full of expensive electronic gadgets.
    D. It’s all but impossible for many teenagers to live without fantastic electronic gadgets.  
    61. What conclusion can we draw from the passage?
    A. Never buy the most updated gadgets.  
    B. You should buy the gadgets with as many functions as possible.
    C. We needn’t always pay the most part to buy the most up-to-date gadgets with many functions.
    D. Never buy the latest model, it’s much too expensive.
    62. Choose the statement most similar in meaning to the underlined sentence in Paragraph2.
    A. Fashionable gadgets are updated in the digital times in a flash.
    B. Fashionable gadgets are transported everywhere in the digital age in the blink of any eye.  
    C. People keep buying and throwing away expensive fashionable gadgets in the digital age in the blink of any eye.  
    D. People use all kinds of fashionable gadgets all the time in the digital age.
    63. What do the words “pros and cons” mean in the selection?
    A. Agreements and disagreements.
    B. The views that are favoured and not favoured by people.
    C. Benefits and bads.  
    D. Advantages and disadvantages.

    B
    As a kid, I can remember going to the supermarket and grabbing eggs off the shelf. I would run them home to my mother because they were usually going into a delicious cake. Times have changed. Cage-free? Organic? Brown? White? Omega-3s(一种脂肪酸)?Help! Here are some tips to help you figure out which eggs you should be eating.
    Brown or white? In fact, color is simply a sign of the breed of hen. Find the freshest egg with the most flavor and let color be a secondary concern.
    Extra Omega-3s? Omega-3 eggs come from a hen whose diet has added flaxseed (亚麻籽)，which produces an egg containing an average of 225 mg of Omega-3 fatty acids and vitamin E. The countless health benefits for humans make these eggs an attractive purchase. My opinion? Eat a piece of fresh fish and get a pure pill of Omega-3s. Let eggs be eggs.
    Does your egg need exercise? Free-range eggs are from hens raised without the limit of a cage, though they may or may not have spent much time outdoors. Organic eggs are from hens whose food must meet organic standards. These hens must be raised humanly, and they must be given time to the outdoors. Hey, happier hens do lay tastier eggs.
    Does local make a difference? Nothing is better than local eggs. They may have a feather or two stuck to them or be a little imperfect in shape and may or may not be certified organic; however, they have one quality. I know exactly where my food came from and how it came into being! In some cases I can even ask the farmer when the eggs were laid and what they were fed.
    55.What’s the best title for this passage?
    A．Which Eggs Should You Be Eating?       B．Eggs Are Changing as Times Are Changing
    C．Which Kind of Egg Is the Best?           D. The First Concern When Choosing Eggs
    56. What does the author think of extra Omega-3s eggs?
    A．They are a good choice for people to buy.   
    B．They contain fewer Omega-3s than fresh fish.
    C．They have the highest content of pure Omega-3s.
    D．They are not the best source of Omega-3s.
    57. The underlined word “free-range” probably means “________ ”
    A．wild        B．cage-free         C．organic        D．Omega-3-free
    58.According to the passage, which of the following has nothing to do with an egg’s quality?
    A．The egg’s color.                         B．The hen’s exercise.  
    C．The hen’s living conditions.                D．The hen’s food.

       Napoleon, as a character in Tolstoy's War and Peace, is more than once described as having"fat
    little hands".  Nor does he"sit well or firmly on the horse".  He is said to be"undersized",with"short
    legs"and a"round stomach". The issue here is not the accuracy of Tolstoy's  description-it seems not
      that far off from historical accounts-but his choice of facts:other things that could be said of the man
    are not said. We are meant to understand the difference of a warring commander in the body of a fat
    littleFrenchman. Tolstoy's Napoleon could be any man wandering in the streets and putting a little of
    powdered tobacco up his nose-and that is the point.
        It is a way the novelist uses to show the moral nature of acharacter.And it turns out that,as Tolstoy
    has it,Napoleon is acrazy man. In a scene in Book Three of War and Peace, the war shaving reached
    the critical year of 1812, Napoleon receives arepresentative from the Tsar(沙皇),who bas come with
    peaceterms. Napoleon is very angry:doesn't he have more army?He,notthe Tsar,is the one to make
    the terms. He will destroy all of Europeif his army is stopped. "Thhat is what you will have gained by
    engaging me in the war!" he shouts. And then, Tolstoy writes,Napoleon"walked silently several times
    up and down the room,hisfat shoulders moving quickly".
        Still later, after reviewing his army amid cheering crowds, Napoleon invites the shaken Russian to
    dinner."He raised his handto the Russian's face,"Tolstoy writes,and"taking him by the earpulled it
    gently…"To have one's ear pulled by the Emperor wasconsidered the greatest honor and mark of
    favor at the French court."Well,well,why don't you say anything?"said he,as if it wasridiculous in his
    presence to respect any one but himself, Napoleon.
         Tolstoy did his research, but the composition is his own.
    1. Tolstoy's description of Napoleon in War and Peace is                 .
    A. far from the historical facts
    B. based on the Russian history
    C. based on his selection of facts
    D. not related to historical details
    2. What did Napoleon expect the Russian representative to do?
    A. To walk out of the room in anrger.
    B. To show agreementt with him.
    C. To say something about the Tsar.
    D. To express his admiration.
    3. Tolstoy intended to present Napoleon as a man who is 
    A. ill-mannered in dealing with foreign guests
    B. fond of showing off his iron will
    C. determined in destroying all of Europe
    D. crazy for power and respect
    4. What does the last sentence of the passage imply?
    A. A writer doesn't have to be faithful to his findings.
    B. A writer may write about a hero in his own way.
    C. A writer may not be responsible for what he writes.
    D. A writer has hardly any freedom to show his feelings.

    Sarah Williams went to a boarding school. Here is one of the letters she wrote to her parents from the school:

    Wentworth Girls’ school

    Beachside

    July 20th

    Dearest Mom and Dad,

    I’m afraid I have some very bad news for you. I have been very naughty and the school principal is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.

    The trouble started last night when I was smoking in bed. This is against the rules, of course. We are not supposed to smoke at all.

    As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away.

    Unfortunately, the cigarette fell into the waste-paper bas­ket, which caught fire.

    There was a curtain near the waste-paper basket which caught fire, too. Soon the whole room was burning.

    The principal phoned for the fire department. The school is a long way from the town and by the time the fire depart­ment arrived, the whole school was in flames. Many of the girls are in the hospital.

    The principal says that the fire was all my fault and you must pay for the damage. She will send you a bill for about a million dollars.

    I’m very sorry about this.

    Much love,

    Sarah

    Colleges are starting to wake up to how sleep deprivation(剥夺) cuts into the academic and athletic performance of their students. All-nighters have become a habit in higher education, but a handful of small new studies help document the consequences.    

    A study at St. Lawrence University in Canton, N. Y., showed what may seem obvious to most: All-nighters are not an effective way to succeed in school

         "You can't do your best work when you’re sleep-deprived," says psychology professor Pamela Thacher, who wrote the study. Thacher studied the sleeping patterns and grades of 111 students to see the relationship between sleep and their GPAs.

         Two-thirds of the students reported that they had pulled at least one all-nighter during a semester. Many students believe that it's a "rite of passage" (标志) to stay up all night during college and that "ifs kind of fun," Thacher says.

         But "if you use all-nighters, your GPA is slightly lower on average," Thacher says. "Pulling all-nighters gives in your (overall) sleep" and makes it difficult to reach full academic potential.

          Short-term side effects of sleep deprivation include delayed reactions and tendencies to make mistakes.

          A Stanford University study may help persuade at least student athletes to make more time for bed. Cheri Mah, a graduate researcher at Stanford, worked with six bas ketball players, who all ran faster and made more shots over a period in which they slept at least 10 hours a night.

          "Athletes who get an extra amount of sleep are more likely to improve their performance in a game," says Mah, who released results from an ongoing study in June. "It's not common knowledge, because if people understood how much of a difference (getting more sleep) could make athletically," they'd apply it more to their lives and not focus solely on nutrition and exercise.

    1. According to the study at St. Lawrence University,

       A. one can reach his potential by staying up late

    B. it takes one all night to recite a passage

       C. the less one sleeps, the more effective his work is

       D. all-nighters affect one's academic performance

    2. The underlined word "document" in the first paragraph probably means_      _.

        A. prove        B. check        C. oppose        D. improve

    3. Which of the following statements is true?

    A. All-nighters are a short-cut to success in school   

    B. All-nighters can make one’s GPAs much higher.   

    C. Staying up late tends to react slowly and make mistakes.

        D. The study may help persuade all students to sleep wall.

    4. According to Cheri Mah,              .

       A. athletes improve their performance only by means of nutrition and exercise  

    B. it is known to all that those who get extra sleep perform better

       C. people don't understand getting more sleep can make a difference  

    D. athletes should sleep as much as possible to run faster

    5. What is this passage mainly concerned about?

        A. A study on all-nighters at St. Lawrence University.

    B. Collage students’ performance suffering from lack of sleep.   

    C Short-term side effects of sleep deprivation.

        D. A Stanford University study on athletes’ sleep.
