The traditional prototype paradigm of ELT,which assumed that a non-native learner learned English in order to communicate with a native speaker,no longer represents the primary context of the use of English today. Therefore,in ELT,besides learning standard English,sensitivity to English varieties should be cultivated so as to promote communicative competence.展开更多

Different methods have been introduced, tried out and found unsatisfactory. In teaching practice, many have come to favor that although no single ELT method can meet all teaching and learning needs, many ELT methods have valuable insights into ELT that should be drawn on. However, teachers need a set of principles to adapt their teaching procedure to the specific circumstances. This paper, through a case teaching plan, presents how to apply varies teaching methods to design teaching plan under the guide of teaching principles.展开更多

The teachers' main task was to try to give the letters of the target language the sound values they normally convey to the literate native speaker. Pronunciation teaching was thus only a preparatory task for getting as quickly as possible to the real problem of language teaching: language contact and language input.展开更多

They occur as lens or boundins within the Altun Group and Dakendaban Group respectively which previously were considered as metamorphic basement of Tarim block and Qaidam block. Our studies indicate that the eclogites outcrop in both the Altun and North Qaidam Mountains show similar occurrences, associated country rocks, rock and mineral assemblages, p\|T\% estimates, geochemistryand protolith feature and ages of peak metamorphism (see table) . The garnet\|omphacite\|phengite geothermobarometer gave equilibrium condition of \%p\%=2 8～3 0GPa and t =820～850℃ for the Altun eclogite and p =2 8GPa and \%t\%=730℃ for North Qaidam eclogite respectively(Fig..2). These p\|T conditions are in the coesite stability field. Moreover, Po lycrystalline quartz pseudomorphs after coesite have been identified in the Dulan area, North Qaidam Mountains (Song et al, in review). Therefore, these features suggest that both eclogites of Altun and North Qaidam Mountains probably are a same HP\|UHP metamorphic belt formed from the same of Early Paleozoic age deep subduction and collision, and subsequently displaced by the Altyn Tagh fault.The case is similar to the Dabie\|Sulu HP\|UHP metamorphic zone which was truncated by the Tanlu sinistral strike\|slip fault and splitted it into two distincts, the Dabie region and Sulu region. These correlations support an about 350～400km displacement of the Altyn Tagh sinistral strike\|slip fault (Fig.1).展开更多
