Best way to learn a foreign language

In my opinion, the best way to learn a foreign language is staying in the country which you want to speak their language. This can create a good situation for you that you have to speak and listen this kind of language. In this country, everything you see and hear is the foreign language. Although you maybe not feel comfortable at first, soon you can find that you learn more in your daily life from anywhere or anyone.
In a class is the normal way that we learn something because when we don't know the answers, we can ask our teachers. They know what students need and what the mistakes we always make so that they should teach us in the best ways. Instructors teach the students in a great and specific way that what the language is; however, you can also learn the oral language from outside.
Actually, going outside of class is a great way to study a language because sometimes you have already known the knowledge that your instructor told you before. If you pay attention in your way home or in a supermarket, you can find there are more native things that you can learn likes what you can say in the different situation as a native speaker.
