Wikipedia is an online encyclopedia(百科全书).This name is a combination of“wiki" and “encyclopedia". Wiki is the Hawaiian word for quick. Wiki websites are designed to enable users to make addition or edit any page Of the site.

Wikipedia has been accused of exhibiting systemic prejudice and mistakes.Critics argue that Wikipedia's open nature and a lack of proper sources for much of the information makes it unreliable,

Mention Wikipedia within the walls of academy and you'll find no shortage of opinions.That-s no surprise.Can an online encyclopedia that is edited by anyone be trusted as a credible information source? Should students be encouraged to use this tool? And is it even possible to discourage its users?

To find out, we performed a simple experiment.We selected 100 terms from the U.S.history textbooks, We chose a mix of items that students might be asked to research for a test or paper and we entered each item into Google to find out which websites the search engine suggests as the most useful links. The results are shocking. Google listed Wikipedia as the number one: 87 times out of 100.

Several conclusions can be drawn from this finding. First, people searching for information about these historical terms are finding the entries from Wikipedia helpful.Second, 6'banning" the use of Wikipedia appears hopelessly simple-minded.Jimmy Wales, one of Wikipedia's founders, told the New York Times, "They might as well suggest not listening to rock & roll either".

To our untrained eyes, the information from Wikipedia appeared just as reliable.The reason why the content is mostly reliable is probably that these terms are rather mainstream.The high-school level content is less likely to be wrong than the subjects studied in graduate schools. So when primary and secondary students are researching history, Wikipedia is still a proper place to start.

The shocking disappearance of Malaysia Airlines Flight MH370 has captured the attention of millions around the world as the search for the airplane and its passengers and crew continues. What happened to the flight’s 239 passengers and crew after the plane left Kuala Lumpur on Saturday? It is becoming an increasingly desperate question as the days pass.

But it’s hardly the first mystery of its kind. Here are some half-solved and unsolved airline mysteries that kept investigators clueless for years.

Air France Flight 447: An Airbus A330 flight from Rio de Janeiro to Paris plunged into the Atlantic Ocean in 2009, killing all 228 passengers and crew on board. But it took a full five days for search and rescue teams to find the wreck(残骸)and another three years for investigators to report that ice crystals had caused the autopilot (自动驾驶仪) to disconnect. The bodies of 74 passengers remain unrecovered.

Amelia Earhart: Ace (王牌) pilot Amelia Earhart disappeared in her twin-engine monoplane Electra over the Pacific Ocean in 1937 in an attempt to circumnavigate the globe. No trace of her plane was ever found even after a multi-million dollar search effort, and Earhart was officially declared dead in 1939.

Flying Tiger Line Flight 739: A U.S. military flight left Guam in 1962 with more 90 personnel headed for the Philippines, but it never arrived. The pilots never issued a distress call, and 1,300 people involved in the U.S. military search never found any trace of wreckage.

British South American Airways: It took more than 50 years to find any trace of the 11 people aboard a 1947 flight that disappeared in the Andes Mountains. A pair of Argentineans rock climbers discovered engine wreckage in the Andes in 1998, and an army expedition later found human remains as well.

Uruguayan Air Force Flight 571: A flight headed to Santiago, Chile carrying 45 passengers and crew crashed into the Andes Mountains in poor weather in 1972, killing twelve people. In the meantime, eight were killed in an avalanche (雪崩) that hit the plane’s wreckage where they were taking shelter, and the rest stayed alive by eating the flesh of the dead before they were finally found more than two months after disappearing out of the sky.
