分析 决心去发现新事物,许多欧洲人在19世纪探索了非洲大陆.

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.Internet:Open to our kids too early
B.Technology:Challenge for everyone
C.Parents:Confused by new technology

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.
