Thanks a lot! =))

I am pretty often hear in music, or english films this sentence: "I don't give a fuck", even Eminem has a same song! So, i thought, what it means somehow like: "Don't make a stupid, bad thing", but you just opened my eyes! In Russia we have same indication of this, but it's too very rude word and it is from one word... =)

"don't give a fuck" means "i dont care at all" but its incredibly rude. like everything in language, it can be insulting or funny depending on how you say it.
"fuck" is a bad/curse word. dont use it around women, strangers, children or old people.

also, write "about" not 'bout. " 'bout" is only typed that way to show a person is rushed in speech or speaks improperly (like huckleberry finn).

<a href="http://conjugator.reverso.net/conjugation-english-verb-have.html">http://conjugator.reverso.net/conjugation-english-verb-have.html</a> it has past/present tense conjugations

the articles are: the, an, a. <a href="http://www.learnenglish.de/grammar/articlestext.htm">http://www.learnenglish.de/grammar/articlestext.htm</a>;
an is used before a word that starts with a vowel sound [a,e,i,o,u] (an apple, an elephant, an umbrella, an igloo, an orange)
a: consonants (a yolk, a cat).

"there is a child" means you are identifying that person to be a child, not an adult etc. "there is THE child". the means thats the child you were looking for or talking about. "the" is for the only one, when a/an is "any one"
