Learning from the Wikipedia

  Last Friday, we finished the third part of Wikipedia modification. The section "Learn How" helps me a lot. I 

chose to check and add reference to Wikipedia. From the section, I knew that for all quotations and

materials whose verfiability are likely to be challenged must include an citation of a source that directly 

supports the material. In addition, the most important spirit of Wikipedia is that the source must be reliable.

  According to the teaching steps, I edited the page which I thought should be modified further. Then I added 

information of the sourse website such as URL, publishers' name, accessdate and so on. Finally, I saved the 

edited page. Work has been finished.
