这个还有些难度，我来试试辨析 一切 vs 全部 我做的一切都是为了你好 Correct 我做的全部都是为了你好 Wrong or Sounds odd 一切反动派都是纸老虎 Correct 全部反动派都是纸老虎 Wrong or Sounds odd 全部的书都在这里了 Correct 一切的书都在这里了 Wrong 我的全部行李都已经搬运完毕了 Correct 我的一切行李都已经搬运完毕了 Wrong 试着通过这些例子来体会，我的体会是 1 一起 is like anything, it includes an infinite amount of things. It's to emphasize just how huge it is 2 全部 is more like everything here, it includes a finite amount of things, could be a lot, could be a few, but are well defined. Wow, even Chinese can be this hard for me~

一切 everything when you are not at my side, everything is you.当你不在我身边，一切是你。 when you are at my side, you are everything. 当你在我身边，你是一切。 全部 = 所有: all usually 所有 is used before an noun as an adjective, but 全部 can be used alone too. 哪些同学通过了考试？全部都通过了。 你喜欢哪几种颜色？所有的颜色我都喜欢。

you just asked a very "difficult " question!^____^ i suggest that you try to figure out the question in this way ,find yourself some english sentences ,and translated them into chinese ,than you ask people if these sentences are good ,in this way ,maybe you would understand it better.
