从你的角度来看各种各样的语言在一个脑子里会不会和谐相处？ Why when I write grammatically correct phrase in Chinese, Chinese people can understand that this text was produced by foreigner or a person with some sort of mental disorder. How can be foreign language learned without interfering with other languages acquired before? When I learn something in Chinese sometimes I can use Chinese patterns in my mother languages unconsciously. But I want to use language patterns and structures separately only in their own language environment without spoiling other language....
