This eassy is about the learning of English language in an English-speaking country which is the best way but it is not the only way to learn language. Academic learning is benificial in terms of covering all aspects of the language like grammer, pronunciation and symbols but I agree that this is not the only way to learn English language.
In educational institutes, English language is taught as an academic subject in Englsh-speaking countries which is benificial but in my opinion there are two more ways to master the language. Firstly, to create environment to use what is learned in the institute and secondly, research.
For learning any language including English a proper atmospher is required. Lets say, student may spent four hours in the institute for learning where a proper English learning environment is available but rest of the time is crucial in polishing the learned skills. For that, a proper environment is required outside the instute. For example, home or work location are the places where a student need to focus on. If non native English speaking family or friends are there at home and normally communicate in mother tounge then there is need to change the routine and involve other members of the family to communicate in English rather than mother language.
Secondly, like other academic subject, students spend their time in libraries or online research, similarly English language learning student also need to do some research other than only taking lessons in the class. They can start reading English newspaper or magazine in libraries, search different dictionaries for vocablury improvement and search online for useful materials.
I agree that studying the English language in a English-speaking country is best but need some more ways in improvement in learning like create an environment with family and friends and do research either in libraries or online.
