Wikipedia

  The internet is very helpful, we can check out thing's information for free.

But you cannot trust Wikipedia too much. Base on the word Wiki means a website that everyone can add, or edict content. Pedia comes from Ecyclopedia. So the volenteers can put any wrong information in it, and even kids can change it. You can change it too.  

  So do not trust it to much, just check the other website's information and see if it is the same. If it is not, then, do not trust any of them.
