sedteaching),这种方法更注重语言在实际运用中功能的实现,在课堂上语言知识的输入以各种真实的资料为主,如面试采访、公告、菜单等,要求学习者使用所学的英语知识在实际生活中完成某一具体任务,这样就突出了语言的功能性特点。对于高级英语学习者来说,提供真实的语境是当务之急,学习者可以通过大量观看原版英文电影、英语电视节目以及用英语写影评、日记等方式来弥补缺少真实语境的不足,另外尽可能多地和外教或本族语是英语的外国人交流并充分利用互联网最大限度地使自己接触自然真实的英语语境。Chapter3InterlanguageBehavioristLearningTheoryLanguagelearningtheoryislikeanyotherkindoflearninginthatitinvolveshabitformation.ButitisnotadequatetoadequatelyaccountforL2acquisition,sincelearnersfrequentlydonotproduceoutputthatsimplyreproduceinput.Habit--stimulus--responseconnectionAmentalisttheoryinlanguagelearning❖
