(except L1 interference, errors were caused by other more factors.)nError analysis prevailed in 1970s. nCorder : first raised error analysis (“the significance of learners errors”) 對比分析與誤差分析兩種研究方法體系 強硬派：兩語之間的差異性決定 教學的難點和重點對比分析 溫和派：從語言

4、習得的過程與規(guī)律。n偏誤分析是第一個關注學習者的語言系統(tǒng)的理論，提出了調(diào)查學習者語言系統(tǒng)的研究方法。The definitions of Errorsa. A classical definition was given by Corder (1973:295-61) as breaches of code, that is, they are the signs of an imperfect knowledge of the code, for the learners have not yet internalized the formation rules of the foreign

James (2001:1) defines errors simply as unsuccessful bits of language.d. Richards and Platt (2002:159) regards error as the use of

Corders Classification of ErrorsPre-systematic errors occur when learners are in a communicative situation where appropriate forms of language are not available to them because of lack of

20、 knowledge . At this stage, the learner is not able to correct his error or explain it, or get his point across in another way.nBy systematic errors, the language learner already knows the linguistic rules system but not really master them. A systematic error usually cannot be corrected by the learn

21、er, but he can explain his error in the sense of providing, in different wording or structure, alternative linguistic messages that get his point across and let the hearer know what he was driving at. nIn the post- systematic errors stage, learners have grasped a certain correct rule, and can use it

22、 correctly. They make errors because they forget the rule for the moment. As for this kind of errors, learners can correct them by themselves and explain why. But learners at this stage may get fossilized when they failed to correct their own errors.n1. “前系統(tǒng)偏誤” n學習者不知道目的語規(guī)則，也不知道為什么選擇了某種規(guī)則形式；n2. “系統(tǒng)偏

MisorderingsSome Other Major Classifications: Interlingual Error and Interlingual ErrornRiehards

26、 (1974) and some other researchers distinguish between interlingual and intralingual errors. an error which results from language transfer, that is, which is caused by the learners native language/ Interlingual errors mainly result from cross-linguistic interference at different levels such as phono

27、logical, lexical, grammatical or discoursal etc e.g. a)Substitution of /t/for /and /d/for / b)Shortening of long vowels e.g. Shanghai learners often make /ei/and /i:/ short vowels, thus, sheep and meat sound like ship and mit.Interlingual errors examplesn L1: Chinese. L2: English 1. I want to marry

30、y or partial learning of the target language.Intralingual errors may be caused by the influence of one target language item upon another.e.g. He is comes from the blend of the sentences He is coming and He comes.nThis classification could help the teacher deal with the relationship between L1 and L2

31、 in teaching practice, to trace the origin of errors, and to decide what language points need more attention. Obviously, the understanding of intralingual and interlingual error enables teacher to perceive language teaching form a two-way perspective, which is different from traditional teaching whi

32、ch only emphasizes target language. nOvert error &Covert error nOvert error is easy to identify because there is a clear deviation in form, as when a learner says:nI runned all the way.nCovert error occurs in utterances that are superficially well-formed but which do not mean what the learner in

33、tended them to mean.nIt was stopped.Input Error and Output Error nIn terms of communication, errors are be classified into input and output errors in considering the channels of input and output. nIn other words, errors occur in listening or reading are called input errors and those occur in writing

34、 and speaking are output errors. Global errors & Local errorsnGlobal errors : those affect the meaning of the whole sentence or semantic relations between sentences, and thus can interfere with communication. e.g. I ate a lot so I was hungry. nLocal errors: those that do not affect the meaning o

35、f the whole sentence significantly. e.g. There is many milk in the bottle.Common Error and Individual ErrornIn class (or classroom) environment, errors can be distinguished as common errors and individual errors. Common errors refer to the errors committed by the majority of students. If only a few

36、individuals commit this type of error, it is an individual error, and by doing so teacher could deal with them accordingly. Frequent Error and Occasional ErrornFrequent errors refer to errors occur in high frequency. For example, if the error he is my sister frequently appears, it could be interpret

37、ed as a frequent error. Occasional errors are those occur in low frequency.n Linguistic Error and Content ErrornGenerally, people tend to emphasize more on the linguistic form, (i.e. lexical errors and structural errors) but ignore the content errors such as pragmatic failure and cultural inappropri

38、ateness. nIn a sense, content error is more important, because it can cause misunderstanding and even cultural shock. For example, Your handwriting is so beautiful. No, my handwriting is worse than yours. ExplanationnFind the reasons “why did the learner commit this error？” nMaking hypothesis about

41、85%。母語遷移的偏誤只占3%。 Ignorance of rule restrictionsnSome learners are very careless and they do not notice the restrictions of some rules, thus applying rules to contexts where they cannot be applied. This can result from analogical extension.n For example, nIts said that time flew could never get back.

42、Incomplete rule applicationnThis is the converse of overgeneralization, which is called under generalization. When learners fail to fully develop a structure, they tend to apply rules incompletely. In this case, the learners fail to learn the more complex types of structures because they find they c

44、ative intention. When engaged in conversation, speakers often have difficulty in expressing themselves. n communication errors are the results of unique strategies employed by language learners to solve the immediate troubles, and therefore, are positive errors. 1. paraphrase. For example, in put on

45、 my school cloth. school uniform.2. code-switching. there are two Hehua(荷花) pools in my school.induced errorsnSome errors result more from the classroom situation than from either the students incomplete competence in TL grammar or L1 interference. This is what we call induced errors. A teacher may

46、mislead students by the way he defines a lexical item, explains a structure, or organizes class activities in a less planned order. nIn addition, faulty materials may cause errors. If students learning materials are unsuitably selected or unscientifically complied, students will be unable to link ti
