Dear Carolyn Hartnett Thanks for welcome.I work as an administrator of a computer's network.It can be said that English is my hobby but I'm still at the beginning I think. I have more question.For now I can mention some problems with application of enlish prepositions and sometimes def. and undef. articles.Recently I found the sentence "He shot a final arrow from his bow". My book of english ^ grammar couldn't explain something like this. Merry Christmas and Happy New Year. rasto
