about possessive adjectives and pronouns

Possessive Pronouns指人的所有物，例mine, his hers, ours等。
This cat is (mine).
Mary has lost her pet. Is this (hers)?
留意Its要放在noun前，例如：
Its bone, its leg, its kittens…

Possessive Adjectives用在名詞前說明人的所有物，例my, your, his, her等。
It is (my) house.
She lost (her) key
It’s (John’s) car.
當你表達2人所有時， “ ’s ” 放在第二個名子後：
May and June’s house
