    10．A recent report found 46% of parents agreed that their child knew more about the Internet than they did．And now new research shows parents are turning to their children for lessons in technology．
    The new study of around 1，000parents showed that 67% of parents have asked their teenager children for technology-related advice.44% have asked their teenager for help using the Internet，and 41% have received teen advice about how to use the TV or home entertainment system．
    Ahad Surooprajally，a father of five children，says his children help him with technology in the home．"They've grown up surrounded by technology，"he explains．"We have four computers and four iPads in our house．If I want to know something technical they're the ones I go to．"
    He says his nine-year-old son Habeeb is the only person in the house who really understands the TV．So he tells Habeeb which film he wants to watch and Habeeb connects his mobile phone to the TV．"You teach your kids everyday life lessons，but the tables are turned when it comes to technology，"says Ahad．
    As well as learning how to use technology properly，there is another advantage of parents asking their children to help them understand the digital world，They may be able to get a better understanding of what their kids are doing online．
    Will Gardner of the charity Childnet International says，"We have to continuously encourage parents to find out more about what their children are doing on line．If the kids are using a social networking site，get them to show you around it if you are not using it already．"

    51．What do we know about the new study？A
    A．Over two-thirds of parents turned to their teenagers on tech matters．
    B．Most teenagers know more about the Internet than their parents．
    C．About half of the parents have no idea how to use a computer．
    D．Few parents trust their children to give them advice．
    52．What does the underlined part"the tables are turned"probably mean？C
    A．The duty is carried out．B．The pleasure will increase．
    C．The situation is changed．D．The difficulty becomes less．
    53．Will Gardner seems to suggest that parents shouldB．
    A．try to learn how to make friends online
    B．keep an eye on children's online safety
    C．encourage children to use social networking sites
    D．ask children to teach them how to use computers
    54．Which of the following can be the best title for the text？D
    A．Internet：Open to our kids too early
    B．Technology：Challenge for everyone
    C．Parents：Confused by new technology

    7．John was part of my childhood growing up in the 1970s and a link to sunny，fun-filled days spent on the beach at Bangor in the Northern Ireland where we went for our summer holidays．To many，he was a mystery．Every afternoon John would wander to the end of the pier（码头） where he fed the seagulls（海鸥）and delighted in the sound of their excited cries as they flew around his head．
    Often I asked my family questions regarding John．Eventually I gave up as no one could tell me anything about him．As I grew up，my visit to the beach became less frequent，and my memories of John buried in a child's imagination．
    Last year memories came flooding back as I walked along the coastline，where I noticed a lady feeding the seagulls on the pier，and I decided to introduce myself．Then I came to know that the lady was John's daughter，and after John left this world she carried out the ritual （惯例），which had held such importance for her father．
    In some strange way I felt we shared a bond，each needing to remember．In return，Lucy told me of John's life，his days in the British Navy（海军）during World War I and how he almost lost hope when his ship was attacked by a German U-boat in the North Sea and he found himself in a lifeboat with five others．
    Close to death，he thought he heard the sound of wings．He put up his hands，only to catch a seagull that had landed on the side of the boat．The seagull saved the lives of the six men as it was used to catch fish，which kept them alive until they reached land．This period of John's life was one he never talked about．But the ritual he first performed as a young man remained a part of him until he died．
    Now I visit Lucy as often as I can，just to chat or very often walk along the beach to the pier end．We enjoy the comfortable silence，each lost in special memories．
    66．Seeing John feeding the seagulls，the author might feelC．
    A．proud    B．worried      C．curious     D．guilty
    67．Why did the author introduce herself to the lady？D
    A．She wanted to make more friends．
    B．She was also fond of feeding seagulls．
    C．She was told the lady was John's daughter．
    D．She was attracted by what the lady was doing．
    68．John survived（从…中幸存下来） the attack because ofA．
    A．a seagull  
    B．a German U-boat
    C．his daughter  
    D．the British Navy
    69．We can infer from the text that JohnB．
    A．once served in both world wars
    B．was a man with a grateful（感恩的）heart
    C．spent all his life in Bangor
    D．joined the navy in the 1970s
    70．What does the author mainly tell us in the text？C
    A．She expressed her thanks to a seagull that saved her life．
    B．She told us the story of how she made friends with a lady．
    C．She shared with us her memories of a man who fed seagulls．
    D．She talked about her childhood spent on the beach at Bangor．

    11．Parents used to rely on physical punishments to control their children's bad behavior，which has been proven to be very harmful．Therefore，most parents now choose to simply yell，thinking that language probably won't hurt as much．But is that really so？
        Using harsh words such as"lazy"or"stupid"is just as harmful as hitting，according to a new study carried out at the University of Pittsburgh，US．"It cannot reduce or correct their problem behavior，"said Professor Ming-Te Wang，leader of the study，in an interview with The Wall Street Journal．"On the contrary，it makes it worse．"
        In the study，which involved 976 two-parent families，researchers asked the kids about their behavior problems，while asking their parents how often they had yelled at them． Nearly half of the parents admitted that they'd shouted at their children in the past year．Researchers noted that the kids whose parents used more harsh words experienced more behavior problems after-wards，including fighting，stealing，lying as well as symptoms of depression．
    "Adolescence is a very sensitive period when kids are trying Lo develop their self-identities（个性）．When you yell，it makes them feel they are not capable，and that they are worthless and useless，"Wang said．"This may explain why so many parents say that no matter how loud they shout，their teenagers don't listen．          
    While harsh yelling can stop bad behavior in the moment，it doesn't teach children to behave how parents want them to，according to Professor Alan Kazdin of Yale University，US．What parents need is to praise their children for good behavior．If parents really need to punish their kids，they should try things like taking away smartphones and reminding them that good behavior will get themback． After all，"we want to teach kids，not hurt them，"said Kazdin．
     
    46．How do most parents react to their children's misbehaving now？C
    A．Letting them alone．
    B．Beating them．
    C．Shouting at them．      
    D．Praising them．
    47．The study finds that using harsh words．A
    A．can make things even worse  
    B．inspires children to do better
    C．corrects children's bad behavior
    D．has a better effect than hitting
    48．According to Professor Ming-Te Wang，D． 
    A．physical punishments are sometimes necessary
    B．children are more self-centered in adolescence
    C．parents should never punish kids for misbehaving
    D．harsh yelling damages children's self-confidence
    49．In Professor Alan Kazdin's opinion，parents shouldC      
    A．set good examples for their children
    B．take away their children's smartphones
    C．praise their children for good behavior
    D．always think in their children's shoes
    50．What does the underlined word"them"in the last paragraph refer to？D
    A．children            
    B．bad behaviors      
    C．parents  
    D．smartphones．

    12．A dog's tail can tell you a lot more than you might think．Is it wagging（摇）to the left or is it wagging to the right？
    "The direction of tail wagging does in fact matter，"said Giorgio Vallortigara，a professor at the University of Trento in Italy．Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog．
    What's the difference between a left wag and a   right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds-German Shepherds，Beagles，Boxers，Border Collies and some mutts．They find that if a dog wags its tail to the left，it's feeling anxious or nervous．The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog．But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable．
    "The tail is a very important signal，"said Thomas Reimchen，a biologist at the University of Victoria in British Columbia，Canada．"There is a lot of visual information that dogs use when communicating with each other．"
    How did the scientists figure all this information out？They had the dogs in their study watch videotapes of other dogs．When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool．But when the dog on the tape wagged its tail to the left，the other dogs got anxious．
    The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously．They suspect that it might be something the dog does without even thinking about it-kind of like when you get goose bumps if something scares or startles you．They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging．As Reimchen said，"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before．"
     
    64．Professor Vallortigara'study focused on the relationship betweenB．
    A．a dog's state of mind and its owner's feeling
    B．a dog's state of mind and the direction of its tail wagging
    C．a dog's sense of direction and its state of mind
    D．a dog's intention of tail wagging and its feeling      
    65．According to the study，dogs which wag their tails to the left may feelD．
    A．calm        B．happy         C．angry         D．anxious
    66．It is implied in Thomas Reimchen's words in Paragraph 4 thatC．
    A．dogs'tails play an important role in their growth
    B．dogs show their feelings only by wagging their tails
    C．dogs get to know others by watching tail wagging 
    D．dogs can understand each other by repeating tail wagging
    67．How does the passage mainly develop？A
    A．By asking and analyzing questions       
    B．By making comparisons．
    C．By following the order of time．
    D．By providing examples．
