[Help] I need help for my presentation/thesis

  I can't understand it.It is too hard to me.

Here are some small suggestions...
I think in the beginning part, you'd better attrack ur audiences' attention, for it's a 1-h presentation. U can add some small cases or events(related to nowadays hot topics) to draw their attention. And then, put on those statistics and phenomenons.
example: Britain left EU's impact on RMB→illustrate stability or sth. else (I didn't search about those information. So there might be some mistakes…)
Ps. I was attracted by ur French helps...

For the first sentence, 'recent year' is grammatically wrong. Better change it to 'recent years', or simply use 'recently' would be perfectly fine.

Oh one more thing, if you use 'recently', delete the word 'in' in front of it.
