English preposition and article. How does it use them correctly ?
In my entries, I make some mistakes about use of english prepositions "by" , "from", "in ", but especially when using "to" or "at".
In add, I have a bit of difficulty with use of the determinative article "the" and with the indefinite article "a or an".
I need to have grammatical english rules, because when I write or speak, I translate using grammatical italian rules. Can some one help me ? If the answer is too long, you can send a link to my skype contact: graziano6539. Thanks alot
