    9．Many facts suggest that children are overweight and the situation is getting worse，according to the doctors．I feel there are a number of reasons for this．
    Some people blame the fact that we are surrounded （包围） by shops selling unhealthy，fatty foods，such as fried chicken and ice cream，at low prices．This has turned out a whole generation of grown-ups who seldom cook a meal for themselves．If there were fewer of these restaurants，then probably children would buy less take-away food．
    There is another argument that blames parents for allowing their children to become overweight．I agree with this，because good eating habits begin early in life，long before children start to visit fast food shops．If children are given fried chicken and chocolate rather than healthy food，or are always allowed to choose what they eat，they will go for sweet and salty foods every time，and this will carry on throughout their lives．
    There is a third reason for this situation．Children these days take very little exercise．They do not walk to school．When they get home，they sit in front of the television or their computers and play computer games．Not only is this an unhealthy pastime（消遣），it also gives them time to eat more unhealthy food．What they need is to go outside and play active games or sports．
    The above are the main reasons for this problem，and therefore we have to encourage young people to be more active，as well as steering them away from fast food shops and bad eating habits．

    5．According to the text，what kind of children may eat more unhealthy food？B
    A．Those who often take exercise．
    B．Those who often watch television．
    C．Those who often have meals at home．
    D．Those who often walk to school．
    6．The author thinks that children are becoming overweight becauseD
    A．their parents often cook meals for them
    B．they are too busy to go out and play
    C．they can't choose what to eat
    D．there are too many fast food shops around
    7．The word"steering"underlined in the last sentence most probably meansB．
    A．forcing       B．guiding        
    C．driving       D．moving
    8．The main purpose of the text is toC．
    A．tell a story    
    B．provide facts    
    C．give advice     
    D．compare opinions．

    10．On my first job as sports editor for the Montpelier Leader Enterprise（MLE），I didn't get a lot  of fan mail，so my attention was caught by a  letter on my desk one morning．
        When I opened it，I read："Sweet piece of  writing on the Tigers．Keep up the good work．"It was signed by Don Wolfe，the  sports editor． Because I was a teenager（being paid the grand total of 15 cents a column inch），his words could not have been more inspiring，I kept the letter in my desk drawer until it got old．Whenever I doubted I had the right stuff to a writer，I would reread Don's note and walk on air again．
        Later，when  I got to know him，I learned that Don made a habit of  writing a quick，encouraging note to people in all walks of life，"When I make others feel good about themselves，"he told me，"I feel good，too．"
        Over the years，I've tried to copy Don and write uplifting words．In a world too often cold and unresponsive，such notes bring warmth．
        Why are positive note writers in such short supply？My guess is that many who shy away from  the  practice are too self-conscious．They are afraid they will be misunderstood．Thus it may cause troubles and problems．And it sounds insincere on the phone，Also，writing takes time；it is far easier to pick up the phone．
        The drawback of phone calls，of course，is that they do not last．A  note attaches more importance to our well-wishing．It is a matter of record，and our words can be read more than once savored （回味） and treasured，and they bring strength and love to us．
        Today  I sent a warm letter to my old boss．I  don't know if it will make his day，but it made mine．As my friend Don Wolfe said．"Making others feel good about themselves makes me feel  good too．"

    56．What does the underlined  part"walk  on air"in Paragraph 2 probably mean？
    （No more than 5 words）
    Become confident．/Feel good about himself．/Become uplifted．
    57．According to the author，why aren't  people  willing  to  write  letters？
    （No more than 15 words）
    Because they may be self-conscious，and writing may cause misunderstanding，and also take time．
    58．Why did the author write to his old boss？（No more than 15 words）
    To encourage him，make him feel good and also the same to the writer himself．
    59．What's  the text mainly about？（No more than 10 words）
    The power of a letter from Don Wolfe．
    60．Were you  encouraged by anybody？And how？（No more than 25 words）
    Yes，I was．When I didn't do well in an exam，my best friend encouraged me to be confident and worked harder．．

    7．I can tell you from experience，both private and public schools have one thing in common．Look around your school．What do you see？Beautiful buildings？Good teachers？I'll tell you what I see：the need to have the most expensive clothing，newest phone，most expensive car，etc．Think about it．Do you find yourself wanting to one-up （胜过） your friends？Be honest．I know I have at some point in time．
      In my school parking lot，for example，there are more BWM's and Mercedes than one could possibly imagine．When I look at my 2006 Honda CRV，the butterflies in my stomach start flapping their wings wildly．Do people look at me differently because my car is old？
      What about my phone？What about text messaging？Earlier this year in my statistics class my teacher asked our class how many texts each student received in the past 24 hours．My count was twelve．Twenty minutes later，people started to come up with the answers of 200 or more．I firmly believe that people were in competition with each other．Who could get the most texts？Having only twelve texts sent to me made me feel terrible．Was it bad that hardly anyone had texted me？My teacher would never have thought that his question which intended a better understanding of the course made me uncomfortable．
      How about the difference between grade levels in high school？Come on．There is a distinct difference from being a senior and a freshman．At gatherings，the senior class boos（喝倒彩） every other grade，sometimes causing fights．Being a senior，I don't want to make negative comments on people in other grade levels．High school is hard enough as it is．Freshman，sophomores and juniors don't need four hundred students to remind them．
      Trying to impress everyone is hard．Most of the stress we have as teens is living up to everyone else's expectations．The only people we need to impress are ourselves．Be in competition with yourself and you'll live a happier life．

    71．What is the common thing between private and public schools according to the writer？C
    A．Good teaching resources．
    B．Great need for advanced technology．
    C．Students'competition for material things．
    D．Having a beautiful environment．
    72．How does a person feel if he has a butterfly in his stomach？D
    A．Proud．  B．Angry．   C．Confident．   D．Nervous．
    73．Why did the teacher ask the students about the number of the texts they received？A
    A．It was connected with what he was teaching．
    B．He wanted to learn about their social habits．
    C．He wanted to make his class interesting．
    D．He tried to stop them texting in his class．
    74．We can learn from the fourth paragraph thatB．
    A．the writer finds it hard to get on well with others
    B．the writer is a considerate person
    C．students in lower grades should be reminded to behave well
    D．fights and quarrels are common between different grades
    75．To live a happier life，teens are advisedD．
    A．to stop buying expensive things
    B．to do things as they are expected
    C．to stop competing with others
    D．to leave a good impression on others．

    4．If humans were truly at home under the light of the moon and stars，we would go in darkness happily，the midnight world as visible to us as it is to the vast number of nocturnal（夜间活动的）species on this planet．Instead，we are diurnal creatures，with eyes adapted to living in the sun's light．This is a basic evolutionary fact，even though most of us don't think of ourselves as diurnal beings．Yet it's the only way to explain what we've done to the night：We've engineered it to receive us by filling it with light．
       The benefits of this kind of engineering come with consequences-called light pollution---whose effects scientists are only now beginning to study．Light pollution is largely the result of bad lighting design，which allows artificial light to shine outward and upward into the sky．III-designed lighting washes out the darkness of night and completely changes the light levels-and light rhythms-to which many forms of life，including ourselves，have adapted．Wherever human light spills into the natural world，some aspect of life is affected．
       In most cities the sky looks as though it has been emptied of stars，leaving behind a vacant haze（霾） that mirrors our fear of the dark．We've grown so used to this orange haze that the original glory of an unlit night，-dark enough for the planet Venus to throw shadow on Earth，is wholly beyond our experience，beyond memory almost．
      We've lit up the night as if it were an unoccupied country，when nothing could be further form the truth．Among mammals alone，the number of nocturnal species is astonishing．Light is a powerful biological force，and on many species it acts as a magnet（磁铁）．The effect is so powerful that scientists speak of songbirds and seabirds being"captured"by searchlights on land or by the light from gas flares on marine oil platforms．Migrating at night，birds tend to collide with brightly lit tall buildings．
      Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times brighter than normal，throwing nearly every aspect of their behavior out of joint，including their nighttime breeding choruses．Humans are no less trapped by light pollution than the frogs．Like most other creatures，we do need darkness．Darkness is as essential to our biological welfare，to our internal clockwork，as light itself．
       Living in a glare of our own making，we have cut ourselves off from our evolutionary and cultural heritage-the light of the stars and the rhythms of day and night．In a very real sense，light pollution causes us to lose sight of our true place in the universe，to forget the scale of our being，which is best measured against the dimensions of a deep night with the Milky Way-the edge of our galaxy-arching overhead．

    66．According to the passage，human beingB
    A．prefer to live in the darkness
    B．are used to living in the day light
    C．were curious about the midnight world
    D．had to stay at home with the light of the moon
    67．What does"it"（Paragraph 1）most probably refer toA
    A．The night
    B．The moon
    C．The sky
    D．The planet
    68．The writer mentions birds and frogs toB
    A．provide examples of animal protection
    A．show how light pollution affects animals
    B．compare the living habits of both species
    C．explain why the number of certain species has declined
    69．It is implied in the last paragraph thatD
    A．light pollution does harm to the eyesight of animals
    B．light pollution has destroyed some of the world heritages
    C．human beings cannot go to the outer space
    D．human beings should reflect on their position in the universe
    70．What might be the best title for the passage？C
    A．The Magic light．
    B．The Orange Haze．
    C．The Disappearing Night．
    D．The Rhythms of Nature．

    6．With just a few minutes left before school was to start，my six-year-old son，Dustin，was pouting （撅嘴）．"I don't want to go，"he said．Ever since he'd entered the first grade，he has hated school．What's going on？I thought as he walked slowly out of the door．If he hates school this much now，how bad will it be later on？
        Every kid sometimes complains about school．But five to ten percent of kids dislike it so much that they don't want to attend school，says Christopher Kearney，director of the Child School Refusal and Anxiety Disorders Clinic at the University of Nevada，Las Vegas．
        If a child seems depressed or anxious about school，fakes illness to stay home，repeatedly winds up in the nurse's or principal's office，or refuses to talk about the school day，you should be concerned，say school psychologists Michael Martin and Cynthia Waltman-Greenwood，co-editors of"Solve Your Child's School-Related Problems"．
        Fortunately，you can usually solve the problem-sometimes very easily．In our case，my husband and I visited Dustin's class and noticed that the teacher，fresh out of college，only called on kids who tried to sit right under her nose quickly．Dustin，who generally sat near the back，was ignored．We simply told him to move up front．He did，and his enthusiasm returned．
    41．What was the author's reaction when her son didn't want to go to school？A
    A．She was worried．B．She was angry．C．She felt nothing strange．D．She felt sorry．
    42．We can NOT conclude that a child hates school if heD．
    A．pretends to be ill at school time          
    B．hates to talk about school
    C．feels depressed when going to school every day
    D．complains about school sometimes
    43．What can we learn about Dustin's teacher from the passage？B
    A．She treats her pupils equally．
    B．She is inexperienced in her job
    C．She gives poor lessons．
    D．She has prejudice against Dustin．
    44．Dustin dislikes going to school because heD．
    A．is laughed at by his classmates          
    B．can't answer the teacher's question
    C．is afraid of his teacher                  
    D．feels he is being ignored in class．
