Influence of our mother tongue

 I learned about the influence of our mother tongue. The language of native country affects our pronunciation. For example, Many Japanese can’t pronounce l and r correctly, because Japanese don’t need to pronounce them when they speak Japanese. However, babies can recognize all pronunciations. I was surprised to hear that, but babies can’t do it as they grow older, because they don’t have to do it. I think that we can do more things to grow up, but we can’t do something as we grow.I think it is interesting, and  I feel pronunciation is difficult again.
