二语习得复习提纲Chapter I Introduction Describing and Explaining L2 Acquisition1.1What is second language acquisition?Second language refers to any language that is learned subsequent to the mother tongue.1.2What are the goals of second language?The goals of SLA are to describe how L2 acquisition proceeds and to explain this process and why some learners seem to be better at it than others.1.3Two case studies of L2 learners1.3.1 A case study of an adult learner1.3.2 A case study of two child learners What do these case studies show us?a. They raise a number of important methodological issues relating to how L2 acquisition should be studiedb. They raise issues relating to the description of learner languagec. They point out some of the problems researchers experience in trying to explain L2 acquisition.1.4Methodological issuesWhat is that needs to be described?a. What it means to say that a learner has acquired a feature of the target language?b. Whether learners have acquired a particular feature?c. How to measure whether acquisition has taken place? (Learner 's overuse of linguistic forms.)1.5Issues in the description of learner languagea. Learners make errors of different kinds.b. Learners acquired a large number of formulaic chunks, which will influence their performance in communication and the fluency of their unplanned speech.c. Whether learners acquire the language systematically?1.6Issues in the explanation of L2 acquisitionItem learning: formulaic chunksSystem learning: rulesInternal (mentalist) account:External account:Chapter2 the Nature of Learner Language2.1Errors and error analysis2.1.1 Identifying errors2.1.1.1 Compare the learner 's language with the normal ones.2.1.1.2 Distinguish errors and mistakes.Definition: Errors reflect gaps in a learner 's knowledgeMistakes reflect occasional lapses in performance.Methods: a. Check the consistency of learners 'performance. b. Ask them to correct their own utterance.Errors and mistakes:2.1.2 Describing errorsMethods: a. error type oriented:b. error maker oriented:Meaning: Classifying errors in these ways can help us to diagnose learners 'learning problems at any one stage of their development and, also to plot how changes in error patterns occur over time.2.1.3 Explaining errorsErrors are systematic, predictable, and some of them are universal: (Learners has constructed some kind of “rule 〞 , albeit a rule different from that of the target language)Eg: omission: leave out the article fhe " , leave out the — in plural nouns Overgeneralization error: eated---ateTransfer errors reflect learners attempt to make use of their L1 knowledge.2.1.4 Error evaluationTypes of errors: Global errors: violate the whole structure of the sentenceLocal errors: affect only a single constituent in the sentence2.2Developmental patterns2.2.1 The early stage of L2 acquisitionSilent period: children make no attempt to say anything to begin with.This period makes a preparation for subsequent production.Trials and errors: Mulaic chunks: they provide learners with the means of performing useful language functions such as greetings and requests. Eg:“How do you do? 〞 “My name is___ 〞Propositional simplification: leave words outEg: “Me no blue 〞2.2.2 The order of acquisitionAccuracy order: there is a definite accuracy order and that this remains more or less the same irrespective of the learner 's mother tongues, age, and whether or not they have receive formal language instruction.2.2.3 Sequence of acquisitiona. The acquisition of a particular grammatical structure, therefore, must be seen as a process involving transitional constructions.b. Acquisition follows a U shaped course of development.c. The process in which learners reorganize their existing knowledge in order to accommodate new knowledge is called restructuring.2.2.4 Some Implicationsa. L2 is systematic and universal, reflecting ways in which internal cognitive mechanisms control acquisition, irrespective of the personal background of learners or the settings in which they learn.b. Some linguistic features are inherently easier to learn than others.2.3Variability in learner languagea. Variability is also systematic , that is, learners use their linguistic sources in predictable ways.b. Learners vary in their use of the second language according tolinguistic context (George playing football/ ..all the time)situational context.(kids/daughter)& psycholinguistic context (prepared/unprepared)c. form-function mappingd. free variation:e. fossilization:石化成因任何现象的出现都不是偶然的 ,是可以追溯出它的原因的 ,二语习得过程中出现的中介语石化现象也是有着根本性的原因的。

Selinker 从中介语理论的分析角度将石化现象形成的原因归 纳为五个过程 :母语迁移、培训转移、二语学习策略、 二语交际策略和目的语过度概括 Selinker 对石化的解释更多的是石化的主要表现 ，而没有找出石化的根本原因 后来,Ellis又对Selinker和 Lamendella 的研究作了如下总结 :(1)内因 :年龄因素 :即当学习者到达一定的关键期 ,他们的大脑失去了可塑性 ,因而就无法掌握某些语言特征 ;缺乏与目的语社会文化融合的欲望 :由于各种不同的社会和心理因素 ,学习者对承受目的语文化标准不做出努力 (2)外因 :交际压力 :持续不断的交流压力要求使用目的语超出了学习者的语言能力导致石化的发生 缺乏学习时机:学习者缺乏获得输入和使用第二语言的时机反应性质：对学生第二语言使用的影响 :肯定的认知回馈 (表示“我明白你的话〞 )导致石化的发生 ;否认的回馈 (表示“我听不懂你的话〞 ) 有助于消除石化应对策略(一)增加二语的输入量 大多数二语的初学者如果得不到足够的二语的陈述性知识 ,就会出现语言的稳定期所以外语教学中 ,当学习者已经到达某种精通程度后 ,应该增加他的二语输入量。

二语的输入既要重视数量又要重视质量课堂教学材料要多样化 ,当前的许多教材应该编辑一系列激发二语学习动机的语境和篇章 ,如报刊文章、海报、广告等学生应尽可能多利用课外听、说、读写资源和任何可以增加二语输入量的时机第二语言的输入应该包括音位知识、语法和词汇 第二语言知识的积累还应该包括相关的文化知识输入 对语言迁移的研究说明学习者对语言 的标志性特征比拟敏感 ,所以某种语言的一般特征而不是可区别性特征更容易导致石化这 样 ,为了防止石化 ,语言学习者需要比拟母语和目的语的文化 ,找出存在于两种语言之间构造表达上的异同来减少母语的迁移二)融合听、说、读、写四种技能促进自动化和认知 以认知理论对二语学习所做的分析为根底 ,针对我国大多数英语学习者产生石化的主要原因，并借鉴 Brown 的建议 ,针对中级学习者 ,我们可以适当采取综合听、说、读、写四种技巧的教 学方法 :第一种是以内容为中心的教学 (content-based teaching), 这种教学以教授某专业的内 容为主 ,把英语作为学习该专业的交流手段 ,学生要想学好专业课 ,必须使自己的英语在听、 说、 读、写等方面都到达一定的水平才能取得成功 ;第二种是以主题为中心的教学 (theme-basedteaching), 这种教学方法围绕某一能够激发学生兴趣的主题或话题组织教学。

例如英语精读课就可以围绕公共卫生、环境意识、世界经济等课题展开教学 ,目前在我国这种方法已被普遍采用 ,但由于教师的准备不够 ,更重要的是由于教材的编制不能满足或跟上实际需要 ,所以没 能到达这种方法的最正确效果 ;第三种是以任务为中心的教学 (task-based teaching), 这种方法 更注重语言在实际运用中功能的实现 ,在课堂上语言知识的输入以各种真实的资料为主 ,如面 试、采访、公告、菜单等 ,要求学习者使用所学的英语知识在实际生活中完成某一具体任务 ,这样就突出了语言的功能性特点对于高级英语学习者来说 ,提供真实的语境是当务之急 ,学习者可以通过大量观看原版英文电影、 英语电视节目以及用英语写影评、 日记等方式来弥补 缺少真实语境的缺乏 ,另外尽可能多地和外教或本族语是英语的外国人交流并充分利用互联 网最大限度地使自己接触自然真实的英语语境Chapter 3 Interlanguage3.1 Behaviorist Learning TheoryLanguage learning theory is like any other kind of learning in that it involves habit formation.But it is not adequate to adequately account for L2 acquisition, since learners frequently do not produce output that simply reproduce input.Habit--stimulus-- response connection3.2 A mentalist theory in language learning? Main ideas of this theory? 1. Only human beings are capable of learning language.? 2. The human mind is equipped with a faculty for learning Ianguage 七anguageAcquisition Device( 语言习得机制〕 .? 3. This faculty is the primary determinant of LA.? 4. Input is needed, but only to 'trigger' the operation of the language acquisitiondevice.3.3 What is fhterlanguaggIt refers to the systematic knowledge of an L2 that is independent of both the target andthe lear ner's L1. .

Paint paint, painting paint, painting, pain ted4. VariableSome researchers have claimed that the systems lear ners con struct contain variable rules. That is, the learners are likely to have competing rules at any one stage of developme nt.Other researchers argue that interlanguage systems are homogenerous and that variability reflects the mistakes lear ners make whe n they try to use their kno wledge to com mun icate.5.learning strategiesLearners employ various learning strategies to develop their interlanguages. The differe nt kinds of errors lear ners produce reflect differe nt lear ninf strategies.6.

They canalways reflect on this implicit knowledge 隐性知识,thus making it explicit.It is also clear that L2 learners may have knowledge about the L2 （i.e. explicit knowledge 显性知识）but be unable to use this knowledge in performanee without conscious attention .6.3 Process ing operati onsOperating principlesThe study of the L1 acquisition of many different Ianguages has led to the identification of a number of general strategies which children use to extract and segme nt lin guistic in formati on from the Ian guage they hear.Examples: avoid in terruptio nrearra ngeme nt of lin guistic un itsavoid excepti onsMultidime nsional modelThis theory sought to acco unt for both why lear ners acquire the grammar of a Ian guage in a defi nite order and also why some lear ners only develop very simple in terla nguage grammars.It distinguishes a developmental and a variational axis.Process ing con stra ints^^Processing constraints典型顺序策略This prevents them from irrterrupting the basic subjectverb-object word order.首位/尾位策略This enables learners to move elements at the end of a structure to the beginning and vive versa.从属句策略This permits movement of elements within m亦n clauses but blocks lhem in subordinate clauses.> Movement along the variational axis is determined by socio-psychological factors.Learners who want to in teg rate into the targetlanguage community progress rapidly along this axisLearners who want to maintain their own separate▲ identities progress more slowly and sometimes not at all.6.4 Commun icati on strategiesAvoid problematic itemsMy brother made me to give him some money.Borrow a word from L1Use ano ther target-la nguage word that is approximate in meaningParaphrase the meaning of wordCon struct an en tirely new wordPsycholi nguistic models to acco unt for the use of com muni cati on strategiesFor example: Claus Faerch and Gabriele Kasper proposed a model of speechproducti on.The model of speech productionA planning phaseAn executnn phaseCommunication strategies are seen as part of the planning phase.Abandon anddevelopreducton strategyMai nta inach leve ment strateg y6.5 Two types of computati onal modelSerial processing:串行处理Information is processed in a series of sequential steps and results in the representation of what has been learned as some kind of ‘ rule ' or ‘ strategy 'Parallel distributed process ing: 并行处理Learners with the ability to perform a nu mber of men tal tasks at the same timeChapter 7 linguistic aspects of interlanguage7.1Typological universals: relative clause当代类型学是从微观的视角研究语言各个层面的类型特征与共性，通过对大量语言的观察， 统计和比照， 从中发现语言的普遍规律和形成这些规律的普遍性制约因素， 并探究其形成动 因，以解释和预测语言可能具有的变化模式， 从而提醒语言开展变化的本质。

当代类型学理 论中的“标记性〞， “蕴含共性〞和“语法层级〞对二语习得研究产生了巨大的影响，开启 了基于类型学理论的二语习得研究路径7.2Universal grammarChomsky argues that language is governed by a set of highly abstract principles that provide parameters which are given particular settings in different language.7.3LearnabilityChomsky has claimed that children learning their L1 must rely on innate knowledge of language because otherwise the task facing them is an impossible one.His argument is that the input to which children are exposed is insufficient to enable them to discover the rules of the language they are trying to learn. This insufficiency is referred to as the poverty of the stimulus.7.4The critical period hypothesis语言学习关键期假设)The critical period hypothesis states that there is a period during which language acquisition is easy and complete (i.e.native-speaker ability is achieved) and beyond which it is difficult and typically incomplete.7.5Access to UG1.

They are complementary rather than as distinct and oppositional(2) Motivation is dynamic in nature.8.3Learning strategiesThe particular approaches or techniques that learners employ to try to learn an L2They can be behavioral: like repeating new words aloud to help you remember them.They can be mental: like, using the linguistic or situational context to infer the meaning of a new word.1. 认知策略 Cognitive strategies ：个人学习时在心理上运用他以前学得的知识经历， 凭经历去区分，选择，思维，分析，归纳，从而获得新知识的一个方法Cognitive strategies are those that are involved in the analysis, synthesis, or transformation of learning materials.eg： Recombination which involves constructing a meaningful sentence by recombining known elements of the L2 in a new way.2. 元认知策略 Meta-cognitive strategies are those involved in planning, monitoring and evaluating learning.eg: selective attention 〔选择注意〕 where the learner makes a conscious decision to attend to particular aspects of the input 元认知策略：主体将自己的认知过程最为认知和意识对象，并对认知活动的全过程 进展不断地， 自觉地监控和调节的执行策略。
