.Is anybody , who is able to check up this ?
That letter is so short , because I have a limit (120-150 words)and definite topic.
Thanks for your last letter from the USA. He [he is used for a person. "it" is used for objects such as letters.] was very interesting. I write to you [you do not need a capital letter here] because I want to tell You a story about my new pet. This dog calls [if it is the name of the dog = "is called"] Pluto. I retell you history- [will tell you] how he became my pet.
One day, I saw the lonely dog - he was attached [tied/chained] to the tree. He was also very hungry. I gave him some food. I began to like him, so I took him home. My parents were surprised but not angry. After a month he began bed eat [to eat his bed/to chew his bed], and we were afraid that he might die. We took him to the vet. From that time he is healthy. Now I must daily go with him to the walk Now I must walk him/take him for a walk every day. That walk is gainful for me too… I’m after that more fitness. That/It is good for me too - I am much fitter.
I must stop writing – my mother calls me. I hope that you write back to me quickly.
