When communicating in Chinese you may often make mistakes using Chinese grammar like:
False:
请你把你的书借我用用,能吗?
Qǐnɡ nǐ bǎ nǐ de shū jiè wǒ yònɡyònɡ, nénɡ mɑ?
True:
请你把你的书借我用用,可以吗?
Qǐnɡ nǐ bǎ nǐ de shū jiè wǒ yònɡyònɡ, ké yǐ mɑ ?
询问对方是否同意做某事的句子末尾,不能用“能”,常常用“可以”(成、行)
能 is never used at the end of a sentence asking for permission. 可以,成 and 行 forms an answer independently.
