论语言变体和语用失误之间的互相影响

第二语言习得的过程是一个自然的连续体。语言变体研究第二语言习得过程中连续体的节．属于语言习得过程的输入。语言变体由系统变体和非系统变体构成，其中又含有个体变体和语境变体。语用失误则将研究的重点放在语用上，注重语言使用者运用语言过程中出现的失误，属于语言交际过程中的输出。语用失误由语用语言失误和社会语用失误构成。两种不同的理论研究共同的对象——语言习得者，从不同的角度来研究语言的习得和使用，这就极大地丰富了语言习得和使用的内涵，对语言的学和教有着十分重要的价值。

Interaction between Language Variability and Pragmatic Failure

The sequence of a second language acquisition is a natural continuum. Language variability focuses on the continuum dots of the second language acquisition, which belongs to the field of a language input. Language variability ranges from systematic variability to non-systematic variability, among which there are sub-classes, such as personal variability and contextual variability. Pragmatic failure attaches its attention to pragmatic usage, which cares much about various ＂errors＂ that happen in the communication and belong to the field of language communication output. Pragmatic failure consists of pragmalinguisitie failure and soeiopramatie failure. These different theories take language learners as the objects of research and perform the study from different viewpoints so as to enrich the connotation of the fields, such as the second language acquisition and language communication and to attach great value to language learning and language teaching
