Wikipedia: The Online Know-It-All
If you want to find out a piece of information about anything, the best place to search for it is Wikipedia. The name “Wikipedia” is from the Hawaiian word wiki, meaning “quick”. This online encyclopedia (百科全書(shū)) is written by thousands of people around the world. Anyone with Internet access can write, add or make changes to Wikipedia articles if he or she finds it incorrect or not well written. In this way, people who know a lot about a certain subject can write about it even if they are not university professors. But contributions cannot damage Wikipedia because many experienced editors are watching pages and techies (技術(shù)專家) can write editing programs to keep track of or correct bad edits. Where there are disagreements on how to present facts, editors work together to arrive at an article that fairly represents current expert opinion on the subject.
Wikipedia is quite different from paper-based reference sources in important ways. Unlike printed encyclopedias, it is continually created and updated, with articles on historic events appearing within minutes, rather than months or years.
What’s more, Wikipedia includes articles written in about 285 languages. This fact makes it one of the few websites on the Internet that are truly international. It was started in 2001 by Larry Sanger and Jimmy Wales, as a free online English-language encyclopedia project. Since its creation, it has grown rapidly into one of the largest reference websites, attracting nearly 500 million unique visitors monthly. There are more than 77,000 active contributors working on more than 22,000,000 articles in different languages. As of today, there are 4,396,866 articles in English.
So, if you are looking for some information, why not try Wikipedia? It’s free, multilingual,and informative.

I’ve always known my kids use digital communications gear (裝置) a lot.But my cellphone bill last month really grabbed my attention.My son had come up to nearly 2,000 incoming text messages,and had sent nearly as many.Of course,he was out of school for the summer and communicating more with friends from a distance.Nevertheless,he found time to hold down a summer job and complete a college course in between all that typing with his thumb.
I was even more surprised to learn that my son is normal.“Teenagers with cellphones each send and receive 2,272 text messages a month on average,” Nielsen Mobile says.
Some experts regret that all that  keyboard jabber is making our kids stupid,unable to read non­verbal cues such as facial expressions,gestures,posture and other silent signals of mood and attitude.Unlike phones,text messaging doesn’t even allow transmission of tone of voice or pauses,says Mark Bauerlein,author of a book called The Dumbest Generation:How the Digital Age Stupefies Young Americans and Jeopardizes Our Future.
Beyond that,though,I’m not sure I see as much harm as critics of this trend.I’ve posted before on how I initially tried to control my kids’ texting.But over time,I have seen my son suffer no apparent ill effects,and he gains a big benefit,of easy,continuing contact with others.
I don’t think texting make kids stupid.It may make them annoying,when they try to text and talk to you at the same time.And it may make them distracted,when buzzing text messages interrupt efforts to noodle out a math problem or finish reading for school.
But I don’t see texting harming teens’ability to communicate.My son is as accustomed to nonverbal cues as any older members of our family.I have found him more engaged and easier to communicate with from a great distance,because he is constantly available via text message and responds with faithfulness and speed.
小題1:What does the underlined word “distracted” in the fifth paragraph mean?

小題2:What would be the best title for this passage?

Technology and the present generation of kids go hand in hand. Taking advantage of this factor, Lim Hojoon, the designer from South Korea, has come up with an educational gadget (小裝置) especially for children. 
Kidget, as the name suggests, is a combination of two words – kid and gadget. This kid-friendly gadget has various uses. When your child is in a mood to read, it takes the form of a storybook. When the mood is to draw and color this wonder gadget turns into a perfect canvas (畫(huà)布). Your child can freely give color to all his/her imaginations. Should he or she wish to have some fun, see this device change into a musical instrument. You too would enjoy doing activities with your loved one using this gadget. This touch screen device will definitely prove to be an ideal friend.
As many parents agree, in this age of technological advancements it is much easier to introduce children to new gadgets than adults. While many adults refrain (克制) from trying out something new, kids are more than prepared to take the leap. Keeping this fact in mind, Kidget is the perfect gift for the child of the 21st century. You will be surprised to see how fast your little one gets acquainted with the device. You might even find yourself lagging (落后) behind at times.
Kidget has another hidden advantage. It helps take the load off young shoulders. With three things rolled into one, a child has much less books, stationary items and related goods to carry. It comes with a promise to make life simpler for kids. Not only is it simple to use but also easy to carry along. The stylish protective case comes with a belt attached to it. Children up to 14 years of age, the targeted audience, enjoy the freedom that comes with it.

Many people think of the brain as a mystery. They don't know much about intelligence and how it works. When they do think about what intelligence is, many people believe that a person is born smart, average, or dumb — and stays that way in the whole life. But new research shows that the brain is more like a muscle — it changes and gets stronger when you use it. And scientists have been able to show just how the brain grows and gets stronger when you learn.
Everyone knows that when you lift weights, your muscles get bigger and you get stronger. A person who can't lift 20 pounds when he/she starts exercising can get strong enough to lift 100 pounds after working out for a long time. That's because the muscles become larger and stronger with exercise. And when you stop exercising, the muscles shrink and you get weaker. That's why people say “Use it or lose it!”
But most people don't know that when they practice and learn new things, parts of their brain change and get larger a lot like muscles do when they exercise. Inside the cortex (皮層) of the brain are billions of tiny nerve cells, called neurons. The nerve cells have branches connecting them to other cells in a complicated network. Communication between these brain cells is what allows us to think and solve problems. When you learn new things, these tiny connections in the brain actually multiply and get stronger. The more you challenge your mind to learn, the more your brain cells grow. Then, things that you once found very hard or even impossible to do — like speaking a foreign language or doing algebra (代數(shù)) — seem to become easy after learning them for a period of time. The result is a stronger, smarter brain.
Scientists started thinking that the human brain could develop and change when they studied animals' brains. They found out that animals that lived in a challenging environment were more “perspicacious” — they were better at solving problems and learning new things.
小題1:According to the first paragraph,________.
A.the function of our brain is like that of the muscle
B.until now it's impossible to explain the brain's mystery
C.many people believe one's intelligence is naturally determined
D.one's brain grows stronger as the age increases
小題2:Training muscles is compared to ________.
A.using the brain
B.connecting things in your brain
C.lifting weights
D.doing research about the brain
小題3:What is Paragraph 3 mainly about_________?
The complex structure of the brain.
B. How changes in the muscles affect the brain.
C. The importance of the brain.
D. How the brain becomes stronger by learning new things.
小題4:What does the underlined word “perspicacious” in the last paragraph probably mean_________?
A.Strong.B.Smart.C.Popular.D.Active.
小題5:The paragraph that follows the passage will most probably talk about _______.
A.the differences between animals’ brains and humans’ brains
B.the relation between human brains and muscles
C.scientists’ findings about animals’ brains
D.how to make your brain smarter through self-development

Most parents of kids under age 8 don't worry about how much time they spend watching TV or using other media, from computers to smart phones to tablets PCs, according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way.
¨We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today. She led a survey of 2,326 parents who have children 8 and younger.It found that in 80 percent of families, children's media use was not a problem, with 55 percent “not too" or“ not at all"  concerned about it. It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity.The exception is video games, which are viewed more negatively than TV, computers or mobile devices.“Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey.
¨The findings exposes a generational shift (轉(zhuǎn)移) in parental attitudes about technology's role in young children's lives," said Wartella.“Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair. "
The researchers identified three media environments created by parents: media-centric (39 percent of families) , media-moderate (45%)and media-light (16%). Children  in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier.And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied.Slightly fewer turn to books (79%) and TV(78%).
The survey didn't look at how media affects children. That's a topic that the American Academy of Pediatrics has handled a number of times. The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat. In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors.¨By limiting screen time and offering educational media and non-electronic formats (格式)such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience. Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy (素養(yǎng)) ," it says.
The pediatricians' group says parents should have “screen-free zones"  and TV should be turned off during dinner. At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content. It is important for kids to spend time on outdoor play, reading, hobbies  and  using their imaginations  in free  play.“ Kids  under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says.
An article on screen time by t.he Mayo Clinic also notes problems linked t.o over screen time, including  being  fat, irregular  sleep , behavioral  problems , weak  school  performance , violence  and  less time for active and creative play.
小題1:Parents have more negative than positive feelings about media consumption like    
A.computersB.smart phones
C.video gamesD.tablets PCs
小題2:Most parents don't worry about kid's media use because        
A.they can limit the screen time
B.they want their children happy
C.they also grew up with technology
D.they can teach their children themselves
小題3:From the data of the survey, we learn       
A.children in media-centric families are smarter than others
B.children in media-light families spend one hour watching TV
C.more than half of the parents think children's media use was a problem
D.media-centric children spend more than three hours each day on media use
小題4:To make parenting easier, most parents probably        
A.try to persuade their children to read books
B.a(chǎn)sk their children questions while watching TV
C.a(chǎn)llow their children watching TV or using computers
D.turn to toys or activities to keep their children occupied
小題5:Which of the following is a suggestion by the researchers?
A.Media use time for babies under 2 should be limited.
B.Entertainment media use should be high-quality content.
C.Schools should provide more time for active and creative play.
D.Home media use should provide platforms for illegal and risky behaviors.

Teenagers at one German school are learning how to achieve happiness alongside other traditional subjects such as math and languages.
The class sit in a circle with their eyes shut and they count from one to ten: someone starts, the next voice comes from the far right, a third from the other side.
The aim of the game is to listen for an opportunity to shout out the number without clashing (沖突) with another voice or leaving a pause. On the first try, most of the young Germans try to be first, while a few are too shy to join in, but by the fifth time round, they develop a rhythm. The message: give other people space but also confidently claim your own. This is a requirement for social well-being.
The Willy Hellpach School in Heidelberg is the first in the nation to develop a happiness course. It is intended for students preparing for university entrance exams.
"The course isn't there to make you happy," Ernst Fritz -Schubert, the school principal, warned pupils, "but rather to help you discover the ways to become happy."
Cooking a meal together is one of the class exercises. Improving body language under the guidance of two professional actresses is another.
The course is taught for three periods a week. Despite the happy subject, the pupils themselves insist it is no laughing matter.
"In the first period, we had to each say something positive about another member of the class and about ourselves. No laughing at people." said Fanny, 17.
Research by the school shows it is not the first to start happiness classes: they also exist at some U. S. universities, mainly based on positive thinking, using findings from studies of depression.
小題1:What's the writing purpose of this passage?
A.To help students struggle against being sad.
B.To describe all the traditional courses.
C.To arouse the readers' interest in happiness.
D.To introduce the happiness course.
小題2:The game intended for the students in the 2nd paragraph is mainly to _________.
A.try their best to get opportunities for themselves
B.practice how to speak in front of people
C.equip them with required social skills
D.confidently speak out one's opinions
小題3:According to the passage, the happiness course is _________.
A.to help students discover the ways to happiness
B.to make all the students happy all the time
C.required to be taken by the first year students
D.created by the Willy Hellpach School
小題4:It can be inferred from the passage that _________.
A.the students can certainly become happy after the course
B.the students just took the course as a laughing matter
C.the students' self'-respect can also improve happiness
D.the students waste time learning something without value

Forbes asked a panel of architects and campus designers to nominate their picks for the best-looking campuses in the world. These are their top choices.
Kenyon College
Gambier, Ohio, US
Mike Evans, a principal at Norfolk, Va., design firm Hanbury Evans Wright Vlattas + Company, says to be beautiful a campus must have a “signature campus space as a carrier of the campus brand.” At Kenyon College, that space is “Middle Path,” a 10-foot-wide footpath that serves as the Gothic hilltop campus’ central artery. More than just a trail, it’s a village green for the tight-knit campus community. Sergei Lobanov-Rostovsky, who teaches 17th-century poetry at Kenyon, says the college, both isolated and pastoral, is “a small place to think big thoughts.”
Oxford University
Oxford, England
Teaching within Oxford’s stone walls dates as far back as the 11th century, and the school is considered a paradigm(典范) for all college campuses. With its labyrinth of quads, cloisters, and archways, it evokes elegance and tradition at every turn. “Its monastic roots and the spectacular quality of its buildings make it an architectural wonderland,” says David Mayernik, associate professor at Notre Dame’s School of Architecture.
Princeton University
Princeton, N.J., US
Princeton’s style is pure Collegiate Gothic(學(xué)院派哥特式); most of it executed in gray stone covered in, yes, ivy. As imposing as these old stone structures are, the campus keeps life on a “human scale” by preserving green spaces and walkability.Sinuous footpaths, archways, plazas – all are designed to inspire spontaneous discussion and learning.
Scripps College
Claremont, Calif., US
The total plan of this women’s college, founded in the 1920′s, has always called for artistic connection between buildings and landscape. Together, architect Gordon Kaufmann, in collaboration with landscape architect Edward Huntsman-Trout, created a distinctively Southern Californian blend of Mission Revival-inspired architecture and landscape, which is lovely, evocative and intact. An expert in deciduous trees, Trout planted rows of liquid amber trees to give the students “a sense of autumn” come fall. He also peppered the campus with tulip trees, sycamores, almond and orange trees, as well as rare shrubs.
Stanford University
Palo Alto, Calif., US
New additions like the Science and Engineering Quad manage to gracefully blend modern and technological elements with the timeless, elegant aesthetics of the campus’ early California Mission Revival architecture. The campus also scores big points for its dramatic entrance via Palm Drive, its romantic Spanish red-tile roofs and myriad patches of green.
Tsinghua University
Beijing, China
Forbe’s panel of architects says natural setting plays a big part in assessing a campus’ beauty. In that regard, this campus is blessed: Founded in 1925, Tsinghua sits on the former site of the Qing Dynasty’s royal gardens. Many of Beijing’s most notable historical sites, like the Summer Palace, are close by. The campus is peppered with artificial ponds where stone benches and floating lotus blossoms inspire reflection.
小題1:In this text, the writer mentioned many best-looking campuses in the world. How many Universities are in America?
A.Six.B.Three.C.Four.D.Five.
小題2:which school is considered a paradigm for all college campuses.?
A.Oxford University.B.Stanford University.
C.Scripps College.D.Princeton University.
小題3:Which University has the style of pure Collegiate Gothic?
A.Tsinghua UniversityB.Oxford University
C.Princeton UniversityD.Kenyon College
小題4: In which part of a magazine can we probably read this passage?
A.Entertainment.B.Education.C.Culture.D.Health.
小題5:Why does Tsinghua University enter the list of the best-looking campuses in the world?
A.because the amber trees give the students “a sense of autumn” come fall.
B.because the artistic connects between buildings and landscape.
C.because its natural setting plays a big part.
D.because it is founded in 1925.

As a professor I have grown accustomed to the opinion regarding American education. We are repeatedly told that American schools are failing, that colleges are not teaching, and that the students of today are not as good as the students of the past.
There are, of course, problems with the education system. Because of economic inequality some schools are significantly better than others and the ideas of equality of education and equality of opportunity are cruel jokes. However, the mere fact that there are some serious problems does not mean that all the dire claims are true.
One stock (陳腐的) claim is that America has fallen behind the world in education in terms of performance on various tests. While the fact that America is behind other countries is a point of concern, there are at least three points worth considering here. The first is the above-mentioned economic inequality which will tend to result in poorer performance when taking the average for America. The second is that many countries have put considerable effort into improving their education systems and hence it is worth considering that America’s decline is also due to the improvement of others. The third is the matter of the measures— do they, in fact, present an accurate picture of the situation? I am not claiming that the data is bad. I am merely raising a reasonable concern about how accurate our picture of education is at this time.
Another stock claim is that American students are doing badly on standardized tests. While there is clearly value in assessment, it is reasonable to consider whether or not such tests are a proper and adequate measure of education. It is also worth considering whether the puzzle with these tests is itself causing damage to education. That is, as teachers teach for the test and students learn for the test, it might be the case that what is being taught is not what should be taught and what is being learned is not what should be learned.
小題1:According to the professor, many people’s attitude towards American colleges is          .
A.negativeB.positive C.a(chǎn)pprovingD.indifferent
小題2:What does the underlined word “dire” in the second paragraph mean?
A.Exact or precise.B.Extremely serious or terrible.
C.Fair or objective.D.Long and boring.
小題3:Judging by the text ,the claims are centered on          .
A.what should be taught in the American classroom
B.fair judgment of American education
C.American students’ performance on tests
D.a(chǎn)n accurate picture of American colleges
小題4:The passage is written mainly to          .
A.defend American education
B.show dissatisfaction with American education
C.explain why American students do badly on tests
D.offer advice on American education reform
