求救求救！外教说是个的语言是与生俱来的，要我们证明之，如何证明？

1)coz language is sth made by us human beings
2)when someone is obliged to doing one thing,then he could only do it.so we learned to communicate by language
3)some scientists have already found that human has the natural language ability

最简单了，告诉他 他生下来就会这门语言就是最好的证明
