Even though we have learned a foreign language after many years of studying, it"s rare to see people speak the language fluently that they have learned. There must be some reason why this happens repeatedly to many people. In this paper we analyse the process of speaking or understanding a certain language from the point of linguistic theory, in order to compare the learning of foreign languages with the acquisition of mother tongues. From the results of this comparison, we suggest that the learning of foreign languages must be performed not by the aid of the mother tongue but directly by way of the languages in question. If the learning of foreign languages is done with the aid of the mother tongue, the students can"t reach the conceptual level where comprehension is operated, and it doesn"t help students develop communicative competence. In case that we attach importance to communicative competence, we must find occasions which let students use the expressions that they have learned. It also means that we must have suitable circumstances for the development of communicative competence.

This study aims to propose a new instruction method about the Spanish rhythm structure. The Korean students of Spanish are very inexperienced in realizing the proper rhythm structure of the language, because in Korean there is not a similar accentual system. To develop a most interesting and effective method for the linguistic rhythm practice, it is necessary that the teachers pay attention firstly to the Spanish suprasegmental phonetic system and secondly to the correlation between the linguistic system and the music system. The fundamental concepts of musical structure involve such factors as rhythmic and pitch organization, dynamic and timbre differentiation, etc. Among the three major elements of the music ― melody, rhythm and harmony ― we have to pay a special attention to the first two, because the two elements are very closely related with the accent position of the words of song, and hereby we describe in detail about the organization of metrical and structural accents as well as their application to the instructional method.
