1、Unit 61 23目录6.1 Contrastive Analysis6.2 Error Analysis6.3 Learner Corpus Analysis1.Try to consider the following questions and get answers to them:Does your teacher of English always make comparisons between English and Chinese in his/her teaching in order to make us understand or remember what you

2、learn?Do you often translate the new English words or sentences into Chinese in your learning?What types of errors do you make most often in your English learning?Why?Do you often analyze your errors in order to avoid them later?2.Make a powerpoint presentation in which you give examples to show you

4、ges in order to determine both the differences and similarities between them.6.1.1 What is CA?1)The strong versionIt is possible to contrast the system of one language(the grammar,phonology and lexicon)with the system of a second language in order to predict the difficulties which a speaker of the s

5、econd language will have in learning the first language,and to construct reading materials to help her learn that language.2)The weak versionThis version requires that linguists only use the best linguistic knowledge available to them to account for observed difficulties in second language learning.

6、It does not require the prediction of those difficulties,and conversely,of those learning points which do not create any difficulties.6.1.2 Hypotheses of CAThe procedures of contrastive analysis follow four steps:1)Description:a formal description of the relevant features of each language compared;2

7、)Selection:a selection of subsystems predicted to present difficulty in order to establish the comparability;3)Comparison and contrast:the identification of areas of difference and similarity;4)Prediction:identification of possible areas to cause errors.1)Step One:Describing Relevant Features of Bot

9、ological level,the morphemic level and the syntactical level.There is practically little contrastive analysis above the sentence level,let alone the textual or discourse level.6.1.4 Criticisms of CA6.2 Error Analysis6.2 Error Analysis6.2.1 What is EA?6.2.2 Procedures of EA6.2.3 Criticisms of EA6.2.1

10、 What is EA?Error analysis is the method to deal with intralingual factors in learners language.Error analysis aims to 1)find out how well the learner knows the second language;2)find out how the learner learns the second language;3)obtain information on common difficulties in second language learni

12、Errors6.2.2 Procedures of EA1)Confusion of error description and error explanation2)Lack of precision and specificity in the error categories3)Inappropriate use of simplistic classifications for learners errors4)Too much attention to learners errors5)Overstressing production data6)Failure to capture

14、large collection of texts of L2 learners spoken or written interlanguage.The corpus can be voice data or text data,depending on the research purpose.1)contrastive interlanguage analysisThe analysis involves comparisons between at least two corpora.CIA involves four major types of comparison:(1)compa

15、rison of native language and interlanguage;(2)comparison of different interlanguages;(3)comparison of interlanguages of different levels;(4)comparison of spoken and written interlanguages.2)computerized error analysisComputer error analysis is a method which has developed from the traditional error

16、analysis(EA)in applied linguistics studies.It avoids many of EAs problems and is now an important way to analyze L2 learners language output.The crucial difference between traditional EA and computer-aided error analysis lies in the fact that the latter allows for the full context to be presented,an
