Below is a page adapted from About Wikipedia (维基百科) on how to take full advantage of Wikipedia.
Wikipediais a web-based, free-content encyclopedia (百科全书) in many languages.
§Exploring Wikipedia
Many visitors come to Wikipedia to acquire knowledge, while others come to share knowledge. At this very instant, dozens of articles are being improved, and new articles are also being created. Over 3,500 articles have been listed by the Wikipedia community as featured articles. Another 15,000 articles are listed as good articles. Wikipedia is available in more than 280 languages including English. Its related projects include a dictionary, quotations, books, manuals, and scientific reference sources, and a news service. All of these are kept, updated, and managed by separate communities, and often include information and articles that can be hard to find through other common sources.
§Basic navigation in Wikipedia
Wikipedia articles are all linked, or cross-referenced. In every article, there are links to some related articles or Wikipedia pages with further in-depth information. Holding the mouse over a certain link will often show to where the link will lead. There are other links towards the ends of most articles, for other articles of interest, related websites and pages and so on. Some articles may also have links to dictionary definitions, audio-book readings, quotations, the same article in other languages etc.
§Using Wikipedia as a research tool
Wiki articles are never considered complete and may be continually edited and improved. Over time, this generally results in an upward trend of quality and a growing agreement over a representation of information. Users should be aware that not all articles are of encyclopedic quality from the start. Indeed, many articles start their lives as displaying a single viewpoint; and, after a long process of discussion, debate, and argument, they gradually take on a neutral point of view reached through agreement. Others may, for a while, become caught up in a heavily unbalanced viewpoint which can take some time—months perhaps—to achieve better balanced coverage of their subject.
§Wikipedia vs. paper encyclopedias
Wikipedia has advantages over traditional paper encyclopedias. Wikipedia has a very low “publishing” cost for adding or expanding entries and a low environmental impact in some respects, since it never needs to be printed. In addition, Wikipedia has wikilinks instead of in-line (内嵌) explanations and its articles provide not only summaries but also plenty of details. Additionally, the editorial cycle is short. A paper encyclopedia stays the same until the next edition, while editors can update Wikipedia at any instant, around the clock, to help ensure that articles keep up with the most recent events.We know from the passage that Wikipedia________.

Are you single or married? Are you a cat or a dog owner? Do you exercise, or are you a “couch potato” (a person who sits on the sofa all day watching TV, eating and basically doing nothing)? These questions and many others are about your lifestyle．
People in the United States feel that they can choose their lifestyles and even shape their own identities．The great variety of lifestyles leads to constant national discussion of choices that people make．This freedom of choice is fun and exciting, but it also creates stress and uncertainty．In newspapers, lifestyle issues are discussed in the features or style section．In The Chicago Tribune this section is called “Tempo”．People turn to this section for lively discussion on lifestyle choices they face with regard to their personal identities, their families, and their social lives．
Many American people believe that they can make their lives happy and satisfying despite their problems．If they lack confidence or tend to feel anxious, shy, angry, or depressed, they believe that they can change themselves．Self-help books, magazines, and feature articles are filled with advice from experts about steps to take to become a happier or more satisfied person and to improve one’s self-respect．Part of this research for self-improvement is a belief that even one’s own appearance can be controlled．This is why there are so many articles in the newspaper about looking young, wearing the latest fashions, and becoming physically fit．
Lifestyle choices also involve moral and social issues．How should children be raised? How should people behave on a date? How should elderly people be treated? How can people stay happily married? All these kinds of issues are constantly discussed and are constantly changing．Not only are experts such as psychologists consulted, but stars from the political and entertainment worlds are held up as lifestyle leaders as well．In the newspaper, feature articles called profiles discuss in detail the personal lives or public work of movie stars, authors, artists, and exceptional individuals who are not stars．The lifestyle choices these people make contribute to the public discussion of all the issues that people think about．

Scientists have produced new evidence suggesting eating lots of red and processed meat damages health．They found big meat eaters had a raised risk of death from all causes over a 10-year period．In contrast, a higher intake of white meat was associated with a slightly reduced risk of death over the same period．
The US study, based on more than 500,000 people, found those whose diet contained the highest proportion (比例) of red or processed meat had a higher overall risk of death, and specifically a higher risk of cancer and heart disease than those who ate the least．
People eating the most meat were eating about 160g of red or processed meat per day— approximately a 6oz steak．Those who ate the least were only getting about 25g per day— approximately a small piece of bacon．Just the opposite, those who ate the highest proportion of white meat had a lower risk of overall death, and a lower risk of fatal cancer or heart disease than those who ate the lowest proportion．
Meat is a major source of saturated (饱和的) fat, which has been associated with breast and colorectal cancer．In addition, lower meat intake has been linked to a reduction in risk factors for heart disease, including lower blood pressure and cholesterol (胆固醇) levels．The latest study adds to a growing body of research linking high red and processed meat consumption to an increased risk of ill health．Ed Yong, of the charity Cancer Research UK, said, “Evidence from large studies tells us that cutting down on processed food, such as bacon or burgers, can reduce the risk of dying from cancer and other diseases．”
Dr Barry Popkin of the University of North Carolina stressed there were health benefits from eating some red meat．But he added: “The need is for a major reduction in total meat intake, an even larger reduction in processed meat and other highly processed and salted animal source food products and a reduction in total saturated fat．” Dr Mark Wahlqvist, a nutrition expert from Australia, said eating small amounts of red meat—around 30g a day—provided a good source of key nutrients．He said, “Fresh, lean red meat of these amounts is likely to be of more benefit than harm．”
According to the passage, we know ______．
| A．big meat eaters eat a 6oz steak per day |
| B．big meat eaters have heart disease ten years earlier |

Processed meat is a kind of ______．
| A．red meat |
| B．white meat |
| C．vegetable with a similar taste of meat |
| D．meat prepared by producers |

| B．We should eat proper amount of red meat per day． |
| C．We should reduce the amount of fresh, red lean meat． |
| D．We should completely cut out red meat from our diet． |

| A．Too much red meat consumption contributes to ill health． |
| B．A well-balanced diet accounts for a healthy life． |
| C．A higher intake of white meat brings benefits． |

Published March 30, 2011）Albert Einstein’s Theory of Relativity might have a few mistakes—and Jake Barnett has set out to prove it．Between attending college classes at Indiana University-Purdue University Indianapolis (IUPUI) and tutoring his fellow students, Jake is also working on a new theory about the creation of the universe．He happens to be 12 years old．
From an early age, Jake showed an extraordinary interest in stars．When he was 3, his parents took him to a space observatory．He tried to learn as much as he could about astronomy．Jake’s IQ measured remarkably high at 170．
As a baby, Jake was found out with Asperser’s syndrome, a form of autism (孤独症)．Autism causes difficulties in communication and social abilities．People with autism may also have strong interests—like Jake’s interest in the stars at a young age．
The symptoms of autism can range from mild to extremely severe．Asperser’s is one of the milder forms of autism．Sometimes people with Asperser’s, like Jake, develop extremely advanced skills in science, music or art．
When Jake was in elementary school, his parents worried that the effects of his Asperser’s were worsening．He became quiet．And he was withdrawing from people．So a doctor recommended that Jake’s parents let him study more advanced subjects, like math and physics．
Jake’s mother asked an astronomy professor to let Jake sit in on his class．Now, Jake studies advanced sciences like electromagnetic physics at IUPUI．
But Jake thinks it’s important to have a normal life too．He likes to play Guitar Hero with his friends and watch science fiction movies．He also enjoys playing classical music on the piano．But for Jake, studying physics is the most important thing．Jake’s professor, John Ross, is working on getting a large sum of money for him to do research at the university．
Doctors have said Jake’s autism symptoms have lessened over time．Still, Jake proudly refers to himself as an “Aspy”, or someone with Asperser’s．In an interview with his university student newspaper, he said, “I think the autism is the reason I’m even at IUPUI．”What did Jake want to do at IUPUI?
| A．Get a degree in astronomy． |
| B．Put forward his own theory in physics． |
| C．Become an Albert Einstein in the future． |
| D．Teach his fellow students Theory of Relativity． |
Which of the following is the correct order of the events that happened to Jake?
a．He set out to disprove Einstein’s theory．
b．He began to study math and physics．
d．He was found out with a mild form of autism．
| A．b-d-c-a |
| B．d-b-c-a |
| C．b-a-c-d |
| D．d-c-b-a |
