Sometimes, when students make mistakes, they do not comprehend why this occurs. Just because they are in front of the situation that when living in a foreign country, they are not corrected straightaway. This is a matther that for most that are settled at any place outside their fatherland are exposed. Commonly, in English Speaking Countries, learners are wrong in sense, but Natives do not vision that circunstance ramdonly. This is what makes teachers be worried about the future of thier language learners. In front of speaking time, there must be more chances to be corrected in a appropriate moment. Except that, who cares about when you do not belong to that region? Really hard, isn´t is? So, what is the best piece of advice that a learner could recieve? I just tell you do not be afraid of making mistakes, but practice makes you perfect. However, the best teachers do not necessarily have to be from native regions, the best teacher is yourself making a commitment with your current expectations about what is also available in the language, but using common sense and well-built knowledge.
