anything
1) 任何事情/东西， 可以用在肯定句/否定句/疑问句中。
如:You can take anything you like. Do you have anything to say?
There is not anything you like here.
2)everything 的疑问/否定形式。
如：--Is there anything in the box？ --No nothing.
He has not anything to do today.
everything 所有的事情／东西，如：Everything here is all right.
另外：not anything =nothing ; 而 not everything 并非／不是所有的东西／事情
anything 和everything的区别就在于：anything不是指所有的，而everything是所有的
追问everything不能用于肯定句吗
追答可以
