Letter

Dear Sir,

I am writing you to express gratitude for your services in all this these years, in which you have been working with us.

I know that all your pupils are very thankful for your teaching. I have always had good references about you and your job. More than ninety per cent of your pupils have been passed the final exam. In addition, you have been a good partner with the rest of the teachers of at school, so we will miss you.

I wish hope you now now spend much more time in on your favourite hobby besides teaching: to traveling. (I am guessing that teaching is his job, not his hobby)

I hope we will meet up next weekend for have a lunch and if you want, we could go to play golf after.

Yours faithfully, (Faithfully is for romantic partner or maybe a boss. Is that what you mean? How about "Yours truly" or "Sincerely")

PS: The exercise is a letter for a partner at my work who was retired and I don't know if in this case, the type of letter could be formal o informal. Thanks! If it's a close friend at work, you can probably go informal. If you aren't close with him, formal may work.

Great job! 

Hi there!

Hi everybody! I'm Matías from Argentina. A couple of days ago, someone told me about Italki. I thought... Let's give a try, why not? I started meeting people and learning a lot. I think this website is amazing!
I am studying English for my work, and also for fun. I love it. I know I make mistakes, and if you can correct me, you will help me a lot.
I don´t think I don't write so well. but The worst thing is the fact that I can't understand when English natives speak. Listening to videos/audios made for students think they're is boring. I like to talk on skype to improve my hearing listening.
This is my first post, and don't have so much to say... so... All the corrections are welcome!
Thanks!
See you!

This looks great. Nice job! It´s really easy to understand!

Chipa.

Chipa is a typical Paraguayan food which is very popular and eaten by almost everyone in Paraguay.Foreign people who visit Paraguay surely eat chipa.This food is also a tradition during Holy Week.
But how is it prepared?
Ingredients: eggs, flour, anise, butter, starch, cheese (filling), milk, and salt.It's very easy to make it; just mix all of these ingredients by hand (do not use mixers or blenders).Then to bake it, you need a "tatakuá", which is a kind of oven, for about 20 minutes.The secret is to pay attention when it is getting turns a golden color. Some people use a banana leaf as "protection" because the takakua is extremely hot and you can't keep control of the temperature.
