Hello, I'll try to explain it in english, because my chinese is still very poor. 直接宾语 (fr: objet direct): The direct object answers the question: What? or Who? Ex: J'ai acheté un livre (I bought a book). Qu'est-ce que j'ai acheté? (What did I buy?) Un livre (a book): gender= male; quantity = singular; Direct object Pronoun = le (l'). Je l'ai acheté = I bought it. 间接宾语 (fr: objet indirect): Here you are a short, simple, general and not very formal explanation: The indirect object is the person who gets the direct object. Ex:J'ai donné un livre à ma mère (I've given my mother a book). OD: un livre; OI: à ma mère. Indirect object pronoun: LUI (à elle): Je LE (OD: un livre) LUI (OI: à ma mère) ai donné (I've given it to her). Hope it helps. I
