You recently took part in an exchange programme in Canada where you stayed with a Canadian student for four weeks. The editor of the English language newspaper at your college has now asked you to write an article for the newspaper, describing what you enjoyed about your visit, explaining any problems you had and encouraging readers to take part in the exchange programme.
A few weeks ago, while I was walking in a corridor of my college and having a chat with a classmate, I came across an original[original is the wrong word here, what are you trying to say?] advertisement for an exchange programme in Canada. I thought at once it could be a very interesting and fruitful chance to improve my English, so I made up my mind to try it. I decided to go to Canada for four weeks. The programme was very clear and I enjoyed the vacation[say experience - vacation is pretty specific to a beach or sight-seeing holiday or so forth] so much. They found me a family
where to stay[to stay with] and I spent the [entire] four weeks with them. They managed to make me feel at home and I soon grew fond of them. I shared the room with a 21
years[year] old boy, whose name is Micky, and we had a great time together. He
just[only] spoke English, so I had to try to speak in English as much as I could to communicate with him. The first week it was quite difficult to communicate in English because I had never done it before
and I was not able to do it{this part was redundant}, but in the end I managed to
do it[improve my English] and it was great when we
got started to understand each other.
There was not so much to do in the evenings, so we both usually
used to stay[ed] at home, watching the tv or telling
us about ourselves. Sometimes
her[his] mother, who I'd like to thank for taking care of me and treating me
as a[like her own] child, used to bring us a cake just to make our evenings more pleasent. Her cakes are the best in the world!
If only I think again["Whenever I think" or "even now if I think" ] about her cakes, my mother[hopefully you meant mouth!]
is[starts] watering!

Anyway, they showed me around all the time I stayed there. I even saw the Rocky Mountain bears! We did not have the
possibility[chance] to go camping because the weather was not that good, so
when[after] going to see the Rocky Mountain[s], we had
already decided to get back home in the evening. Apart from this, I would like to recommend this kind of experience to everybody who wants to take it easy, just spending four great weeks abroad {on second thought, maybe it was a vacation after all!}and, contemporaneously{this means in the same time period, like disco and bell bottoms were contemporaneous - I guess I would say "at the same time"}, to all those people who feel the need to improve their English knowledge with an extraordinary
experience of life[life experience].
You only need to pay your travel costs - and even though it is a little bit expensive, it's worth it! You also ought to take some money to live there[this is called "spending money" money for extra stuff like movies, restaurants, coffee]. You do not need anything else. The results of a
better[improved] knowledge of the English language are assured! So phone the number
that you can find in[for] the exchange programme, call for any types of information and get ready for leaving (for the departure){yes, get ready for your departure}!
