moi en général je présente comme ça:
As an introduction, this is an article extracted from ... (source) published on April 25th 2008. It is about [ou] it deals with ... (sujet).
First of all [ou] to beggin with, we are going to see ...
Then [ou] secondly, we are going to focus on ....
To finish [ou] at last, we will analyse/describe ...
To conclude, we can point out that/ we can say that ...
Par contre... pour olivia92, il faut plutôt dire:
"we will analyse ... and in a second part, we will describe..." et non "we will be analyse" et "we will be describe"
Bon courage ^^
