bonjour,

je vous laisse les indications de correction

'Dear Sir or Madam,

Become ( il faut une nominalisation en ING) Assistant in a foreign country is a very interesting and enriching experience. Indeed after( after + base verbale en ing) to have discover( have + participe passé) this possibility to leave (voc) during few months abroad, I quickly( le choix de l'adverbe n'est pas bon, il s'intercale de plus entre Was et le P.P) was seduced by project.
First, learn (nominalisation en ing) my own culture and my mother tongue at ( préposition à revoir, vous vous adressez à => destination) motivated students would be a real pleasure. Go (nominalisation) to English ( English? non, il faut anglophone) countries is even more interesting because English is a world language and to me, it seems obvious that several months in that country will greatly progress (voc => passez par une structure du type ' make me improve my oral skills) me especially oral. Moreover having free time outside of the course( voc) is valuable because it allows( voc=> ici c'est permettre, autoriser) visiting, to discover( il faudra mettre visit, discover et speak au diapason) the country and to speak a maximum with residents.

I'd say that I am a serious, curious and applied student, therefore participate (nominalisation) in such an experience would be only benefit. I feel that to be tuned to the others and being worried ( worried, c'est inquiet) about their progress, that's why I'm convinced that contact with pupils will work. I am delighted in advance at exchanges and the sharing which this job brings.
The practice of rugby has proved my open-mindedness, my sense of the teamwork and my motivation. In addition this sport was born in England so to be to dive into (calque du français) this universe and into these countries where Rugby 'occupies' a very big place, would be fantastic.

Having rarely to travel (expression à revoir) , this project is a real chance to discover other horizons that is why I hope that my enthusiasm convinced (je passerais par un futur) you.
Please find enclosed my CV. Thank you for considering my request.
I look forward to hearing from you.

Yours sincerely,'

Voilà,

Amicalement
