If you want to find out a piece of information about anything, the best place to search       it is Wikipedia. This online encyclopedia is      (write) by thousands of people around the world. Anyone can add or change the information if he or she finds it not correct or not well written. In this way, people who know a lot about a certain subject can write about it              they are not university professors.

What is more, Wikipedia includes articles written in about 253 languages. This fact makes it      of the few websites (网站) 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. By April 2008, over 10 million articles        ________( put on) Wikipedia. A quarter of the articles are in English. Wikipedia is also a place        people can find the latest news.

However, Wikipedia has its own problems. There have been many complaints that some of the information on Wikipedia is not accurate and some important subjects are not included. This has led to arguments between the writers of the articles. The people      (run) Wikipedia say that the accuracy of the information is improving and that it is one of the top 20 visited websites on the Internet.

So, if you are looking for some information, why not      (try) Wikipedia?
