Some verbs can take two objects: one is the direct object and the other, the indirect object. The indirect object, which is usually a person, immediately follows the verb. The direct object, which is usually a non-person, follows the indirect object.
Such verbs in Chinese are limited and the most common ones are: 给 (gěi: ‘to give’), 送 (sòng:‘to give something as a gift’), 借 ( jiè: ‘to lend’), 还 (huán: ‘to return something’), 教 (jiāo:‘to teach’), 问 (wèn: ‘to ask questions’), 告诉 (gàosù: ‘to tell information’), 通知 (tōng zhī:‘to notify’).
上星期我借小王三本词典，这星期他还我一本。
Shàng xīng qī wǒ jiè xiǎo wáng sān běn cí diǎn，zhè xīng qī tā hái wǒ yī běn。
Last week I lent Xiao Wang three dictionaries; this week, he returned one to me.
(小王 and 我 are the indirect objects.)
王老师教我们语法，他每天都问我们很多问题。
Wáng lǎo shī jiāo wǒ men yǔ fǎ，tā měi tiān dōu wèn wǒ men hěn duō wèn tí。
Teacher Wang teaches us grammar; every day, he asks us many questions.
(我们 is the indirect object.)
