    4．To be successful in any aspect of life，you need to know when to use the carrot or the stick．
    Here are a few tips to help you decide whether it's better to use the carrot or the stick．
    With the kids
    The carrot
    When it comes to raising a kid，the carrot or the stick dilemma is quickly disappearing as too many parents take the carrot approach to the extreme．In child raising，the carrot should never be materialistic things．If you want to ask for good behavior with a reward，it should be with something that can't be bought，say，trust．
    The stick
    Nowadays，no one likes to use the stick anymore，or in my father's case，the belt．I'm not overlooking child abuse，if you ever want to call it that，but I am encouraging parents to toughen up a bit．You don't want your kid to test your limits only to find out he can get away with it．If you want to raise a kid，raise the hand and let him know it comes down on the second offense．
    At the office
    The carrot
    People need encouragement and motivation to perform well．However，the carrot only really works well with employees who have already proved themselves．If you've got someone who can't show up at the office before noon，the promise of a raise isn't going to do much．On the contrary，if there's a guy with a good work moral，he'll thrive（grow stronger） when you add a promotion to the picture．
    The stick
    When considering the carrot or the stick in the office，remember that，overall，the stick is the more practical method in the office．A wise man，who just happened to be an Italian，once said"It's best to be both loved and feared．"It's nice to have everyone love you，but running a business isn't like running a family．You need to have the stick constantly raised．
    With the wife
    The carrot
    When it comes to marriage，always use the carrot．I've had a lovely marriage for many years，and I've always stuck to the carrot approach．
    Sometimes you catch more flies with honey，and sometimes it's the crack of a whip that gets the horse moving．Try not to use too many sticks in the bedroom； the carrot is much more fun．
    51．What is the best title of this passage？B
    A．The advantages of the carrot and the stick
    B．The carrot or the stick？
    C．The introduction to the carrot and the stick
    D．Tips in the daily life
    52．In kids raising，the author prefersC．
    A．neither the carrot approach nor the stick approach
    B．the carrot approach
    C．the stick approach
    D．both the carrot approach and the stick approach
    53．Which do you think is the best to be a good boss at the office？D
    A．Using too many sticks   
    B．Always using carrots．
    C．Eating a lot of carrots  
    D．Being both loved and feared
    54．Which is NOT true according to the passage？B
    A．You need stick to get your horses to move faster occasionally．
    B．The author often gives more carrots to his wife to eat in the bedroom．
    C．The carrot is much more fun when it comes to marriage．
    D．On different occasions，the carrot or the stick is effective．

    11．It seems that people are gradually losing their smartness as smartphones become increasingly important assistants in their lives．As we rely too much on technology instead of our brains，many people have lost three basic abilities．
    The first skill many people have lost is remembering phone numbers．Because phone numbers are stored in smartphone contacts，there3now no need to dial a number or look at it again．This is fine until you need to call someone for help，only to find your phone is not around．
    And some people may also have lost their sense．of direction because some apps can guide people anywhere they want．People get so dependent on them that when they cant use their smartphones，they get lost and anxious．
    But the worst lost skills may be social ones，meaning that some people are becoming so cially inept （无能的）．People often bury themselves in their smartphones．As we're too absent-minded by what's happening in the virtual （虚拟的） some of us have lost conversational skills and sometimes．cant even tell whether a person is happy or not．
    Last August，researchers at the University of California，Los Angeles，studied 51students aged 11and 12．who had over five hours'screen time every day．heir task was to tell the emotions，of 48pictures of faces that were happy，sad，angry or scared．
    The children made an average of 14.02mistakes at the beginning．But after a rive-day camp without electronic products，they made only 9.41mistakes on average．
    Luckily，people still，have a chance to get these abilities back．You should try to keep your parents'numbers in mind for emergencies．You should also pay more attention to street signs and stores，which will help you to draw a mind map and stop you from．getting lost．And the easiest solution to social skill loss is to take a break from electronic products．
    32．The underlined sentence in the second paragraph implies thatD．
    A．you are able to turn to others for help
    B．others are able to call you anytime and anywhere
    C．others are unable to get in touch with you by smartphone
    D．you are unable to contact others without your smartphone
    33．The experiment shows that without electronic products，one couldA
    A．recognize more facial expressions correctly
    B．lose the sense of direction frequently
    C．tell different emotions immediately
    D．tell more pictures of faces easily
    34．Overusing smartphones，people will probablyC．
    A．have no sense of numbers
    B．fail to find their destination
    C．lose face-to-face communication skills
    D．weaken their senses of hearing and sight
    35．What's the writers attitude towards electronic products？B
    A．Objective．
    B．Critical，
    C．Supportive．
    D．Optimistic．
