So you must be a English learner, me too.Now i just wondering how we learned our mother language,very strange,isn't it?We can even speak before we can write when we are very little,and we know exactly what it means,I think it's the countries that speak English made it become a universal language,like UK,USA...they're developed country,but more than that.I mean,they're advanced,so they get the right to influent,people want to learn from them,so first,you have to pick up their language
