　　Ⅰ. CET and its washback effect study
　　CET is an English proficiency test administered by the Ministry of Education in China. It can be traced back to 1987. At present， the test has over 10 million participants annually and the result of the test is recognized all over the country. The test grows in magnitude as well as importance over the years. The score of the test can determine whether a student has the chance to get a promising career after graduation， such as state-owned organizations and enterprises with higher pay. Moreover， the score is used to measure how well a college English class fulfills the requirements of the Ministry of Education. Therefore， there is a trend in college to teach what is likely to appear in the examination.
　　The current CET includes four parts： writing， listening， reading and translation. And listening accounts for 35% of the whole test. After several reforms， now this part includes three pieces of news from VOA and BBC. The translation part focuses mainly on Chinese-to-English translation of Chinese traditional culture. Most students from Pu’er University do not have high English proficiency， especially poor in listening and speaking. Thus， not many students in the university can pass the test.
　　And the influence of language testing on language teaching and learning is called backwash or washback. It was first explained by Pearson as follows： “ public examinations influence the attitudes， behaviors and motivations of teachers， learners and parents， and because examinations often come at the end of a course，， this influence is seen working in a backward direction， hence the term ‘washback’” （Pearson， 1988， P98）. Later， Alderson and Wall （1993） gave its formal definition in their article “Does Washback Exist？” They defined “washback” as the effect of testing on learners as well as teachers to “do things they would not necessarily otherwise do because of the test” （P117）. In addition to these， many a scholar put forward their understanding of the effect.
