    20．You're rushing to work and a man ahead of you collapses on the sidewalk．Do you stop to help？In a study of by-standers，it was found that some people avert their gaze and keep on  walking rather than stop and get involved．
    "There is a tendency to decide that no action is needed．"says a psychologist．"The first thoughts that pop into your mind often keep you from offering help．In order to take action，you have to work against them．"Here are some common thoughts that might prevent you from helping．
    ●Why should I be the one？I'm probably not the most competent（有能力的） person in this crowd．You might think someone older or with more medical knowledge should offer assistance．
    ●What if he doesn't really need my help？The fear of embarrassment is powerful； no one wants to risk looking foolish in front of others．
    ●No one else looks concerned-this must not be a problem．We can follow the people around us，but most people tend to hold back their emotions in public．
    "If you spot trouble and find yourself explaining inaction，force yourself to stop and evaluate the situation instead of walking on，"says the psychologist．"Then retry to involve other people； you don't have to take on the entire responsibility of being helpful．Sometimes it's just a matter of turning to the person next to you and saying，‘It looks like we should do something．'Or asking someone if an ambulance has been called and，if not，to call for one．Once you take action，most people will follow you．"
    56．Which is NOT the common thought that stops you from helping others？B
    A．I'm not the very person capable of setting the problem．
    B．It looks like we should do something．
    C．It must not be a problem as no one else is concerned．
    D．He doesn't really need my help．
    57．According to a study of by-standers，what will some people do when a man ahead falls down on the sidewalk？C
    A．They will call for help and then walk away．
    B．They will stop and offer help．
    C．They will turn away their eyes and go on walking．
    D．They will laugh at him．
    58．We learn from the last paragraph that if we spot trouble，C．
    A．we should call the ambulance as soon as we can．
    B．we should take on the whole responsibility and do something alone．
    C．we should stop and evaluate the situation and try to make other people follow．
    D．we should turn to other people and ask them to take on the responsibility
    59．In order to offer others your timely help，you need toD．
    A．ask others for help and call the police
    B．get along well with the passers-by who spot the trouble
    C．go directly to the police station
    D．work against the first thoughts that prevent you offering help
    60．The main purpose of the text is to tell readersA．
    A．to give others a hand                                    
    B．to be more competent
    C．not to risk looking foolish                    
    D．to stop and evaluate the situation．

    分析 本文是主要讲了根据调查显示，在别人遇到困难时，很多人选择径直走开，而不是提供帮助．心理学家从几个方面分析了其中的原因，并且提倡人们遇到此类情况，要伸出援助之手．

    解答 56．B．细节题．根据文章3，4，5段Why should I be the one？I'm probably not the most competent（有能力的）person in this crowd．和No one else looks concerned-this must not be a problem．We can follow the people around us，以及What if he doesn't really need my help？可知ACD三项都是人们的想法，只有B项不是．故B正确．
    57．C．细节题．根据第一段2，3行In a study of by-standers，it was found that some people avert their gaze and keep on  walking rather than stop and get involved．说明很多人在这种情况下都选择视而不见，继续向前走．故C项正确．
    58．C．推理题．根据文章最后一段前2行"If you spot trouble and find yourself explaining inaction，force yourself to stop and evaluate the situation instead of walking on，"和最后三行‘It looks like we should do something．'Or asking someone if an ambulance has been called and，if not，to call for one．Once you take action，most people will follow you．"可知我们应该做的事情是停下来分析一下具体的情况，看看我们是否能够做什么．故C正确．
    59．D．推理题．根据文章最后一段内容The first thoughts thatpop into your mind often keep you from offering help．In order to take action，you have to work against them．可知我们应该停下来帮助别人，而不是继续向前，不理不睬，认为有别的一些更有能力的人来采取行动．故D项正确．
    60．A．主旨大意题．根据全文内容以及Here are somecommon thoughts that might prevent you from helping本文主要讲述的就是我们在看到有人摔倒的时候，我们应该停下来，判断影响形势和情况，看看别人是否需要我们的帮助．然后再给出我们的帮助．故A正确．

    点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

    11．Americans won't live without cars!Each year there is an increasing number of cars on roads and streets，as millions of new cars are produced．One not of every six Americans work at putting together the parts of cars，driving trucks，building roads or filling cars with gas．
    Most Amorists find it hard to think what life would be without
    a car．However，some have realized the serious problem of air pollution
    by cars．The polluted air is poisonous and dangerous to health．
    One way to get rid of the polluted air is to design a new car that
    Does not pollute．That's what several large car factories are trying to
    do．But to build the new car is easier said than done．Progress in this field has been slow．
    Another way is to take place of the car engine by something else．Engineers are now working on some new cars．Many makers believe that it will take years to develop a practical model that pleases man．
    To prevent the world from being polluted by cars，we'll have to make some changes in the way many of us live．Americans，for example，have to cut down the number of their cars they are encouraged to travel and go to work by bike．Biding a bike is though to help keep the air clean．
    But this change does not come cagily，a large number of workers may find themselves with no jobs if a ear factory closes down．And the problem of air pollution would become less important than that of unemployment．
    56．How many ways to get rid of air pollution are suggested in this article by the writer？C
    A．One．B．Two．C．Three．D．Four．
    57．Large ear feretories are trying to build a clean car，C．
    A．which is clean itself           
    B．which is used to clean streets
    C．which does not pollute the air  
    D．which is easier to make
    58．If the number of ears is cut down，the most serious problem in American workers isA．
    A．to have no work to do           
    B．to keep the air clean
    C．to get a better life                              
    D．to go to work by bike
    59．What is the conclusion of the writer？D
    A．Bicycling is the only way out．
    B．The number of ears must be cut down．
    C．Cars bring us nothing but serious problems．
    D．Cars bring us not only a better life but serious problems．

    15．What makes it rain？Rain falls from clouds for the same reason anything falls to Earth．The Earth's gravity pulls it．But every cloud is made of water droplets or ice crystal（冰晶）．Why doesn't rain or snow fall constantly from all clouds？The droplets or ice crystals in clouds are extremely small．The effect of gravity on them is slight．Air currents move and lift droplets so that the net downward amount of water is zero，even though the droplets are moving constantly．
    It can be seen that droplets and ice crystals behave somewhat like dust in the air in a beam of sunlight．To the casual observer，dust seems to act in a totally random fashion，moving about
    without fixed direction．But in fact dust particles（分子） are much larger than water droplets and they finally fall．The average size of a cloud droplet is only 0.0004inch in diameter（直径）．It is so small that it would take sixteen hours to fall half a mile in perfectly still air，and it doesn't fall out of moving air at all．Only when the droplet grows to a diameter of 0.008inch or larger can it fall from the cloud．The average raindrop contains a million times as much water as a tiny cloud droplet．The growth of a cloud droplet to a size larger enough to fall out is the cause of rain and other forms of precipitation．This important growth process is called"coalescence"．

    68．Ice crystals do NOT immediately fall to Earth becauseA．
    A．they are kept up by air currents
    B．most of them change into steam
    C．they combine with other chemicals in the atmosphere
    D．their electrical charges draw them away from the earth
    69．The underlined word"random"in line 10most probably meansA．
    A．unpredictable     B．strict    C．independent     D．abnormal
    70．What can be inferred about drops of water larger than 0.008inch in diameter？C
    A．They never occur．
    B．They are not affected by the force of gravity．
    C．In moving air they would fall to earth．
    D．In still air they fall a speed of thirty-two miles per hour．
    71．How much bigger is the rain drop than a loud droplet？D
    A.200times bigger
    B.1，000times bigger
    C.100，000times bigger
    D.1，000，000times bigger．

    5．I was i n a terrible mood．Two of my friends had gone to the movies the night before and hadn't invited me．I was in my room thinking of ways to make them sorry when my father came in．"Want to go for a ride，today，Beck？It's a beautiful day．"
    "No!Leave me alone!"Those were the last words I said to him that morning．
        My friends called and invited me to go to the mall with them a few hours later．I forgot to be mad at them and when I came home to find a note on the table．My mother put it where I would be sure to see it．"Dad has had an accident．Please meet us at Highland Park Hospital"．
        When I reached the hospital，my mother came out and told me my father's injuries were extensive．"Your father told the driver to leave him alone and just call 911，thank God!If he had moved Daddy，there's no telling what might have happened．A broken rib（肋骨）might have pierced（穿透）a lung…"
    My mother may have said more，but I didn't hear．I didn't hear anything except those terrible words：Leave me alone．My dad said them to save himself from being hurt more．How much had I hurt him when I hurled those words at him earlier in the day？
        It was several days later that he was finally able to have a conversation．I held his hand gently，afraid of hurting him．
    "Daddy…I am so sorry…"
    "It's okay，sweetheart．I'll be okay．"
    "No，"I said，"I mean about what I said to you that day．You know，that morning？"
        My father could no more tell a lie than he could fly．He looked at me and said．"Sweetheart，I don't remember anything about that day，not before，during or after the accident．But I remember kissing you goodnight the night before．"He managed a weak smile．
        My English teacher once told me that words have immeasurable power．They can hurt or they can heal．And we all have the power to choose our words．I intend to do that very carefully from now on．
    21．The author was in bad mood that morning becauseC．
    A．his father had a terrible accident      
    B．he couldn't drive to the mall with his friends
    C．his friends hadn't invited him to the cinema
    D．his father didn't allow him to go out with his friends
    22．Why did the author say sorry to his father in the hospital？B
    A．Because he didn't go along with his father．
    B．Because he was rude to his father that morning．
    C．Because he failed to come earlier after the accident．
    D．Because he couldn't look after his father in the hospital．
    23．The reason why the author's father said he forgot everything about that day is thatC
    A．he had a poor memory           
    B．he didn't hear what his son said
    C．he just wanted to comfort his son                
    D．he lost his memory after the accident
    24．What lesson did Beck learn from the matter？B
    A．Don't treat your parents badly．
    B．Don't hurt others with rude words．
    C．Don't move the injured in an accident．
    D．Don't be angry with friends at small things．

    9．Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health．This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased．Apple，for example，doesn't want iPhones to come closer to you than 1.5centimeters； Research In Motion，BlackBerry's manufacturer，recommends 2.5centimeters．
    If health issues arise from cell phone use，the possible effects are huge．Voice calls-Americans chat on cell phones 2.26trillion（万亿）minutes annually-earn $109billion for the wireless carriers．
    Devra Davis，an expert who has worked for the University of Pittsburgh，has published a book about cell phone radiation，"Disconnect．"The book surveys scientific research and concludes the question is not settled．
    Brain cancer is a concern that Ms．Davis examines．Over all，there has not been an increase in its incidence since cell phones arrived．But the average masks an increase in brain cancer in the 20-to-29age group and a drop for the older population．
    "Most cancers have multiple causes，"she says，but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer．
    Children are more vulnerable（易受伤的）to radiation than adults，Ms．Davis and other scientists point out．Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）．No studies have yet been completed on cell phone radiation and children，she says．
    Henry Lai，a research professor in the bioengineering department at the University of Washington，began laboratory radiation studies in 1980and found that rats exposed to radiation had damaged DNA in their brains．
    Ms．Davis recommends using wired headsets or the phone's speaker．Children should text rather than call，she said，and pregnant women should keep phones away from the abdomen（腹部）．

    24．According to Ms Davis，brain cancer increaseC．
    A．among children   B．among old people
    C．in the twenties  D．among pregnant women
    25．Why do children easily be affected by radiation？D
    A．Because they haven't grown up．
    D．Because their skulls are thinner and their brains are easily hurt．
    C．Because they use cell phones more often than adults．
    B．Because they are too young to protect themselves．
    26．What can we conclude from the last paragraph？B
    A．Pregnant women should keep cell phones away．
    B．People should use cell phones in the correct way．
    D．When you use a cell phone，use a wired headset or the phone's speaker．
    C．If you are a child，you'd better text than make phone calls．
    27．What does the passage mainly talk about？A
    A．Be careful when using cell phones．
    D．Low-energy radiation could damage cells that could lead to cancer．
    C．Rats exposed to radiation have damaged DNA in their brains．
    B．Don't hold your cell phone against your ear．

    "No pain no gain，"June thought to herself．She continued to swim，realizing her head was hurting and her body was starting to get numb （麻木）．Breathing became （37）B for her and her vision wasn't so （38）A．She saw a lifeguard and a （39）C of other people near the pool，but she decided that there was no sense in embarrassing herself or （40）Aanyone．She continued，and soon she found herself in the middle of the pool．
    She was a bit worried，but by pushing herself she finally（41）B it to the other side of the pool．As she stood in the（42）D water，her body swayed （摇晃） back and forth．Realizing she needed help but unable to even say anything，she leaned against the poolside and stood there．

    Have you ever been in （46）A and chosen not to ask for help？We've all been there．One suggestion is to listen to your instincts （直觉） and（47）B others．There is nothing wrong with that，or June （48）A have drowned．

    When you find yourself （52）A to"keep your head above water"，stop，look around and listen．In such a situation，if you （53）C，you'll almost certainly slip further into trouble．Always take （54）D to listen to your body，and be kind to yourself．You will find that doing so makes the（55）A of life much happier and more fulfilling．
