III. Conclusion
How does the child actually learn to speak ? The answer is sometimes the so-called imitation theory of language acquisition, sometimes comprehensible input, sometimes innate capacity and so forth. Language itself acts as an intermediary between human and his environment. In order to acquire the language, human has to be in this environment, since only the environment can teach him the language. Over the decades, many researchers, linguists, or professors have come up with dozens of theories about how language is learned and learned. Occasionally, many approaches have been put forward in order to improve language education, sometimes to question the validity of what is known about language acquisition and to discover new informations. These consecutive approaches, which have been developed rapidly since certain periods, have provided the basis for some similarities and differences among each other. To sum up, no matter how these approaches are, which involve significant differences and similarities with each other, there is a single point and a single direction that they all carry, and that is to take the second language acquisition further than it was and it is.
