Hi Gorana-the-smart-girl! :)

Ъ (hard mark) = places a short y sound between a consonant and the following vowel. Thus the difference between сел (sel) = "sat down" and съел (syel) = "ate up."
Ь (soft mark) = softens the preceeding consonant. Thus, ть sounds like the t in "Tea," ль like the L in "Lease," and most distinctly, нь is like the Spanish "ñ" in "El Niño." If the soft mark is placed at the end of the word, the consonant is softened to sometning between itself and y, such as шь = the "sh" in "Push." In English transliteration, we indicate it with an apostrophe (') In old folk songs it is frequently extended to become an i, for rhythm's sake, as in this example:
Oi, Leliu, Lada, Mati;
("Bless me, Mother; Oh, Lelia, Lada, Mother! to call the Spring in; bid Winter good-bye.")
Ы = very short "i" as in "Lift"
Ё = "Yo" at the beginning of a word; as the British Ö in midword.
