I read in one book the very interesting subject. 
(Some  Eukaryota can swallow the bacterias and use them as temporary mitochondria.)
is that true?
And does this proof the the evolution?

You are talking about endosymbiotic theory which basically tells us that eukaryotic mitochondria are ancestrally derived from bacteria living symbiotically within other cells.

Some of the experimental support for this theory came from classic experiements by Lyn Margulis. These, along with more intro to the topic are provided here

Does this "prove" evolution? Well science doesn't quite work like that - we falsify hypotheses rather than prove things to be true, but theories come to be accepted as true under the weight of evidence from many tests of many more specific hypotheses. Work on endosymbiosis provides one of many lines of evidence that support our wider theoretical understanding of evolution.
