Hi Sasha(или другое имя)!
How are your? I have just come from the USA. It was wonderfull and I want to come back there...
I want to tell you about my trips to the Grand Canyon and the Mississippi River.It was amazing! I like it very much! 
The Grand Canyon is really beautiful place.  It is one of the most wonderfull places in the world! It looks like split mountains. This place is located very high and sometimes it was dreadfully.
The Mississippi River is located in the USA too! It is very long and beautiful river. I had a water trip on this river and I made some photoes for you. I put them in my letter and you will see it. 
I miss you very much! 
See you soon ,

nowadays we have many electrical things - it is important for everybody and future generation, because our world changes every day and now I would like to tell you about mobile phone and ask on the question "Why do we have mobile phones?".

moveover, mobile phone is important nowadays. it helps to people talk and have meetings and now we can not live without this thing.

we can ring up to our friends, close friends, fimiliars, grandfather, grandmother (grandparents), mother and father (parents). also we can be written to the doctors by phone, can order something, for example, pizza (eating) or furniture or pilets to travel.

mobile phone is very small - it is very good and comfortable for us! we can keep it with us everywhere.

so, i think that mobile phone is important for everybody and helps us in hard situations
