An indirect object refers to a person or a group of people that the action of the verb is done to or for.
一个间接宾语指的是一个人或一群人作为动词指向的客体.
当看到句子中有两个宾语时,其中指物或指事的就是直接宾语,指人（或动物）的就是间接宾语.（不能按宾语离动词的远近来判别）
比方有一句话：“我教他英文.”I teach him English.在这句话里“him”是间接宾语,“English”是直接宾语.
另外有一句话：“昨天我给父亲写了一封信.”I wrote Father a letter yesterday.在这句话里“Father”是间接宾语,“a letter”是直接宾语.
