16、取相關(guān)信息。2）幫助學(xué)生用英語完成語言任務(wù)。五、教學(xué)設(shè)計理念 1）運用任務(wù)型教學(xué)的模式。給學(xué)生設(shè)計出相關(guān)的任務(wù)，要求學(xué)生用英語討論交流，讓學(xué)生學(xué)會用英語完成語言任務(wù)。2）采用“以學(xué)生為中心”教學(xué)模式。讓學(xué)生在小組活動中進行有效的語言學(xué)習(xí)，把學(xué)生自主學(xué)習(xí)、合作學(xué)習(xí)和探究學(xué)習(xí)貫穿教學(xué)過程中，從而激發(fā)主體參與的興趣。六、教學(xué)策略1教學(xué)方法a.
