20.Nothing is more tiresome than being stuck in a boring class.Every second takes ages to tick by.A recent survey of American kids revealed that 91 percent experience boredom.In fact,adolescence is considered a peak period for the problem.One study showed that roughly one in three teenagers was bored at school.
Peter Stromberg,professor at the University of Tulsa says,"Our brains adapt really quickly to certain levels of stimulation(刺激).We get used to the media providing levels of highly emotional stimulation,and when we're not getting them we feel bored.As our society develops various ways of keeping us entertained,we may discover that rather than getting rid of boredom,we're multiplying it."Luckily,new research is implying a way that we can battle the trend.
Professor John D.Eastwood of the University of York developed a new theory of boredom,which links it to the brain's attention system-the part of the brain that we use to focus.Anything the attention system in your brain locks onto will be automatically sucked up into your conscious awareness-it might be a bird outside the window,the pleasant smell of lunch,or even someone sleeping in the back of the class.
The problem is that your attention system doesn't like being told what to do.It wants to focus on stuff that you find fun and interesting.For the parts of school that you enjoy,this isn't a problem.But for those classes that don't interest you,or present too much or too little challenge,the story is very different.In those situations,you're going to have to spend a lot of effort constantly redirecting your attention system to focus on things it would rather ignore.And the effort is going to wear you out.Eastwood describes it as"wanting,but being unable,to be involved in a satisfying activity."It's like a block in the system.And it's the awareness of that block combined with a sense that the environment is to blame that leads to feelings of boredom.
When we're bored we blame the world around us,but Eastwood's theory challenges this assumption:Boredom doesn't exist out there; it exists inside your brain.What that means is-hard as it may be to hear-boring lessons aren't only the fault of your teacher or the subject,they're your fault too.

19.Current Culture:Is Common Culture Alive?
The digitizing and globalizing world is changing the working of culture.As some see it,cities and nations are losing their common culture and their general spirit:people can no longer count on those around them valuing any of the same music or films.Others argue that a common culture is not dying so much as changing forms:it is less and less attached to a particular area and ever more linked to global networks.
The facts lead to the change that anyone can become a cultural producer today,that the culture is increasingly available everywhere you want it,and whenever you want it,not just in the two months after the movie or book came out.Cultural possibilities have multiplied as a result,but the change also means fewer cultural moments.It is easy to find the change in terms of loss of diversity of society.So what will it mean if globalization turns us into one wide world culture?
For the enthusiasts of these changes,culture is not about popular artists or books,but centers on platforms like Google and Wikipedia,where every variety of culture brings about the exchange of knowledge and ideas,and makes connections across boundaries.It is perhaps debatable whether two people who have participated in such websites,but in totally different corners of them,have had a cultural experience in common.In fact,these platforms become very successful with a large crowd of people,who build things together,share information,and forward articles back and forth.
There are still more questions.What does it mean for the future of countries that culture now goes beyond the limits of the nation?Is there anything to defend and preserve in the passing cultural world,or is that merely to favor pen over printing press,horse over automobile?
Up to now a growing quantity of culture has been globally spreading and developing.More individuals (个人) than ever have the chances to be makers of culture,even if that means more to choose from and fewer standards to be reached in common.What it means is this strange feeling:that of being more connected than ever,with one-click access to so much of the cultural harvest around the world,and yet,of being starved for having similar interests and opinions with others,concerned only with ourselves.

A.the missing of common culture

18.Just what is a tiger mother?Amy Chua is a law professor at America's Yale University and her recent book on the subject is making waves.She's been called"dangerous","outrageous",even a"monster"for her descriptions of how she brought up her two daughters.
Her book Battle Hymn of the Tiger Mother describes fighting with a daughter for hours at the piano to ensure the child gets a piece of music right.She rejected birthday cards made for her by her girls because she didn't think they had made enough efforts.She compared one child negatively with the other,threatening to burn their toys.Her rules include:schoolwork always comes first; an A-minus is a bad grade; children must be two years ahead of their classmates in math,and playing the violin or the piano is a must.
Ms.Chua considers the Chinese hard work ethic as a way of creating happy,successful children-at least in her case.Although she's had a large amount of flak for her theories,one thing can't be ignored-the success of Chinese children in the education system.
In Britain,shocking research shows that Chinese girls,for example,are outperforming all other foreign groups at GCSE-79 percent getting 5AC Grades,compared with 58 percent of white British girls.So what is it about Chinese parenting that's leading to high achievers?And how do Amy Chua's theories play into that success?
She told me that if her daughter came back from school with 96/100 in a test,Chua would ask her what happened to the other4points.It's about always knowing"you can do better",she told me.
Interestingly,in China,the birthplace of the tiger mother,people are moving away from traditional Chinese parenting.They are following more western parenting styles.

B.consider her a very successful mother
C.realize their methods of bringing up children are wrong
D.don't think highly of her methods of bringing up her children

A.She is very strict with her children.
B.She doesn't think her children are clever.
C.She is very interested in playing the piano.
D.She knows playing is important to children.

A.Chinese parents don't think grades are very important
B.Chinese children are cleverer than British children
C.Chinese parents are proud of their children
D.Chinese children do well in their study
