    14．If you ________ the medicine yesterday，you ________ well now．（　　）
    A．took，might beB．had taken，might have been
    C．had taken，might beD．took，might have been

    分析 如果你昨天就吃药的话 现在就应该好了，

    解答 答案：C  这是错综时间条件句．从句和过去的事实不相符，主句与现在的事实不相符，从句用过去完成式，主句用would/should/could+do，所以本题选择C．

    点评 考查此类考点，要注意句中的时间或隐含的时间，同时注意主句和从句不同的结构．

    9．Last spring，members of Alaska's Troop 34，based in Fairbanks，trudged （跋涉） out into the snowy wilderness to take part in their state's Take a Kid Trapping program．In many parts of the state，beavers （海狸）are pests and need to be controlled．
    The 10-to-12-year-old girls found out where beavers lived，set traps，and skinned the two animals they caught．The girls hope to catch ten more beavers so that the entire troop can make mittens and hats with the fur．They also want to cook beaver meat．
    Troop leaders and members say the Scouts are doing a good deed by helping control the state's beaver population．But animal-rights activists say trapping is cruel．They want the Girl Scouts to stop in their tracks．
    Beavers aren't only causing a problem in Alaska．Residents in Sampson County，N．C．，have turned to a local committee to help them battle the growing beaver population there．
    County landowners are frustrated after the county spent more than  50，000 in eight years trying to reduce the beaver population through a government program．The joint state and federal program included paying money to trappers for every beaver carcass  they trapped．
    Many local residents say that the program didn't work because there were too few trappers．That's why the county set up its own committee to investigate other ways to control the area's beaver population．
    The county will rely on its own beaver-trapping program．It has hired a trapper to set traps in various areas．The county will pay 10 for every beaver carcass．
    Why do many people say that beavers are a nuisance？For beavers to survive，they need lots of water．Water provides the large rodent （啮齿动物）with a place to hide from meat-eating animals．Beavers also store food underwater for the winter．When there's not enough water in a particular area，beavers get busy building dams．
    Beaver dams can cause major flooding and damage to the surrounding countryside as the animals cut down trees to use in their construction projects．Beavers build canals to transport heavy objects．
    59．What is Alaska's Troop 34？C
    A．A team of the Boy Scouts．
    B．An army．
    C．A team of the Girl Scouts．
    D．A sports team．
    60．Why does the troop hope to catch ten more beavers？C
    A．To fulfill their task．
    B．To sell them for money．
    C．To get enough fur．
    D．To exchange them for mittens and hats．
    61．Which of the following statements is true？A
    A．Sampson County has to find a new way to control the beaver population there．
    B．The government program in Sampson County has proved to be a success．
    C．The local government has controlled the number of beavers in the County．
    D．More and more trappers now start to set traps in Sampson County．
    62．Local residents hate beavers because they canD．
    A．cause damage to dams
    B．block up canals with heavy objects．
    C．do great harm to construction projects．
    D．badly damage the environment and cause floods．

    6．Over the last 15years，digital communication has brought in more changes than the printing press did in 1570．And those most likely to use them in this world are teenagers，whose brains appear to have an extraordinary volume to adapt to the world around them，according to Dr Jay Giedd，a（n） （51）Bbrain expert．
    We are now discovering that，as a species，our brains during the teenage years are still flexible and capable of （52）C．Having a more flexible brain，（53）A，means that certain parts of it，such as desire control and the ability to make long-term decisions，haven't developed yet，which may also explain why we spend a（n） （54）D period living under the protection of our parents rather than leaving home at the age of 12or 13．This also means that the teenage brain can adapt to new technology，enabling teenagers to（55）A the increasing pace of digital technology and giving them an advantage when it comes to multitasking．
    In the USA，on average teenagers spend 8.5hours a day using computers，mobiles，and other devices to learn，interact，and play．This increases to 11.5hours if you include all of the（56）B that goes on，such as talking on the phone while watching TV．As they stare at these screens，they're taking in and sorting through an incredible amount of information．
    There are （57）C about how social media is affecting the way the brain learns to  （58）D，as one of the most important skills that we learn as children is how to make friends and interact with people around us．Geidd says that a lot of what goes on inside our brains is social．Social interactions are now being （59）A by technology-you could have hundreds of friends，all of whom are real people that you interact with and scientists aren't sure whether we'll be able to develop the same（60）D using social media．
    There is a（n） （61）A of the growing digital trend：YouTube shows the teenagers all over the world are watching the same videos and laughing at the same jokes，indicating that they are more （62）B than teenagers in the past．They may be keen on （63）B their friends and posting updates on social media sites，but teenagers today are probably going to have access to technology and （64）Bsocial and educational opportunities that anyone with a less flexible brain may have trouble imagining．Nevertheless，there is a cut-off point，and by the age of 30，our brains in their ways，making it more（65）C for us to adapt and cope with new technologies．
