Ahoj, chtěla bych vás poprosit, jestli byste mi zkontrolovali formální stránku motivačního dopisu, který musím přiložit k přihlášce na Erasmus. Předem moc děkuju 

Dear Sir/Madam,
I would like to express my interest in the Erasmus+ programme to get a chance to study abroad.
There are several reasons why I have decided to apply for an Erasmus exchange at our partner university abroad. I am currently a student of the Faculty of Business and Management at the Brno University of Technology. So my field of study at a selected foreign university is very close to me. Also attending courses that are not teaching at my university would extend my horizons. I would very appreciate to have the chance to experience different styles of education.
Another reason is that I could move my limits, rely on myself and consolidate my personality.
At last but not least I would be able to speak fluent English, which would be an unbeatable advantage in my future career. I would be able to speak Portuguese, as well. I would meet new friends from all over the world, get to know the local culture and discover the beauty of this country.
To sum it up, the experience I would gain from studying at a foreign university would brings me application in further studies, personal development and future career. I would be grateful if you give me chance to represent our university in foreign country.
More information about me, my qualifications and skills are available on my CV which I am also enclosing as an attachment. I believe that my background and expertise meets the requirements of the tender.
Thank you for your time and considering my request. I look forward to your response.

Yours faithfully,

V.
