First notebook entry: Introducing myself

Hello!

I am learning English, because I want to make friends from the UK and the USA. I have already been already in the UK, and had [alternative: and experienced] a lot of problems trying to speak English. I am working as a taxi dispatcher of a taxi in Moscow, and if I am [1] able to speak English pretty well, I will receive a higher salary. I have got [2] two small children. My eldest daughter is five, and practices aesthetic gymnastics. The youngest [3]  is two years old.

[1]  After "if", the present tense often can refer to the future.  Please see this page:   http://www.efl.ru/forum/threads/33070/

[2] "have got" isn't wrong, only more informal.  In conversational English, a person would probably say, "I have" or "I've got".

[3]  "smallest" isn't wrong.  But the sentence sounds more "balanced" contrasting "eldest" and "youngest".
