1、On the Role of Language Input and Language Output in Second Language AcquisitionABSTRACTNowadays, the phenomenon of fake prosperity in language teaching in China has sparked a hot debate. Many language learners who take part in exams such as IELTS and BEC find that it is difficult to get a high scor

In addition, many college students who passed the exam of CET4 and CET6 cannot use English appropriately, even though they have learned this language for over 10 years. The root of this phenomenon is that Chinese students always neglect th

5、过程中，忽略了语言学习的本质，更突出的问题是割裂了“语言输入”与“语言输出”之间的关系，在外语学习的过程中没有给予两者同等的重视。有鉴于此，通过学习Krashen的语言输入理论以及swain的语言输出理论，笔者意图通过本研究揭示“语言输入”与“语言输出”在外语教学过程中的关系与作用及其两者间的平衡对二语习得产生的重要性，并借此提高广大外语学习者对此的重视程度。摘要：语言输入 语言输出 二语习得 ContentsAbstract.摘要.Literature Review.11.1 Input Hypothesis.11.1.1 An Overview of Input.31.1.2 The Li

9、erican applied linguist, in the late 1970s and the early 1980s, is an all-round theory concerning second language acquisition (SLA). Meanwhile, it is the most influential and controversial theory in second language acquisition research. Such influences still exist till now. Krashens Input Hypothesis
10、 is similar to Chomskys theory on first language acquisition in some respects, such as the function of Language Acquisition Device (LAD) in the process of language learning.Krashen states that language input plays an identical part with Language Acquisition Device. Together with language input, a le

12、ia hearing and reading) input language that contains structure “a bit beyond” his or her current level of competence. In other words, the language which learners are exposed to should be just far enough beyond their current competence that they can understand most of it but is still challenged to make progress.Krashens widely known and well-accepted theory of second language acquisition has had a large impact in all areas of second language research and teaching since the 1980s. The theory consists of five main hypotheses.(1) The acquisition-learning hypothesisKrashen believe
