《第二语言习得入门》内容简介：The purpose of this book is to1. introduce SI,A as an independent field of study,2. review the linguistic and pedagogic aspects of SLA,3. define the key concepts of SI,A,4- view critically existing theories of SLA,5. understand the individual learner differenccs,6. analyze learner language,7. discuss the SLA research methods.

By "system" we mean the recurring patterns or arrangements or the par-ticular ways or designs in which a language operates. All elements in thesystem of a language are arranged in accordance with certain rules; theycannot be combined at will. In English, for example, "brip" is not an ac-ceptable word; "He tables a green" is not an acceptable sentence, either. Itis because the sounds that are used to form words and the words that areused to form sentences do not appear at random, but are arranged and usedin fixed patterns according to certain systems or rules so that speakers of alanguage can understand one another. If a language were not systematic, itcould not be learned or used consistently.By "arbitrary vocal symbols" it is meant that anything that representssomething else is a symbol, for example, a dove is the symbol of peace.These symbols are not chosen for any particular reasons, but at random.That is to say, the relationship between the sound symbols and the objects,events, or ideas that these symbols represent are arbitrary. Language is ar-bitrary in the sense that there is no intrinsic connection between the word"pen" and the thing we use to write with. Although the choice of certainsound symbols to represent certain objects, events, or ideas is arbitrary,once the relationship is established, it becomes a fixed convention; i.e., theuse of these sound symbols is by no means arbitrary, but follows certainconventions that speakers of the language have agreed upon. It is becausethe sounds and words of a language are used in fixed ways that the speakersof the language can understand one another, thus making communicationsand interaction possible.
