常見錯誤
What are common mistakes with "Its"?Which "Its" sentences look correct but are wrong?
×The cat licked it's paw.
✓The cat licked its paw.
「its」是所有格，表示「它的」，不需要撇號。 「it's」是「it is」或「it has」的縮寫。
×The dog wagged his tail.
✓The dog wagged its tail.
當動物的性別未知或不重要時，應使用中性所有格代名詞「its」，而不是「his」或「her」。
×Every student must bring their textbook.
✓Every student must bring his or her textbook.
「Every student」是單數，理論上應搭配單數所有格「his or her」。雖然「their」在口語中常被接受，但在正式寫作中，使用「his or her」或重組句子更佳。注意：此處錯誤是將「its」誤用為「their」，但「its」用於事物或動物，不用於人。
×The book's cover is torn.
✓The book's cover is torn. (This is actually correct for possessive nouns, but learners might overuse 'its' for nouns that should use apostrophe-s.)
此錯誤點在於混淆。對於有生命的名詞（如人、動物）或擬人化的物體，常用撇號+s（'s）表示所有格。而「its」是代名詞的所有格，用來代替前面提過的名詞，以避免重複。不應在名詞後直接使用「its」。
×The tree lost all leaves in the storm.
✓The tree lost all its leaves in the storm.
在表示「某物的...」時，所有格代名詞「its」通常不能省略，否則句子會不完整或語意不清。
