6、tween the simple past tense and present perfect tense. 案例评析：任务型教学目的让学生脱离教材，在乐中学，有任务而学习。本节由学生讲解have/has been to,have/has gone to之间的区别，并表演对话。由学生自己挖掘增强学生记知识点的作用，比以往死记硬背印象会更深。学生展示的内容是每个学生充当“小老师“的角色，自己把所学的、所预习的重点讲解出来，这无疑是提高了学生的表演能力、创造能力、自学能力及社会能力。使老师与学生都逐渐脱离教材。学生轻松掌握两者的区别。那么，一般过去时与现在完成不言而喻，也就理解了。同时分组讨论合作

10、re.3案例评析： 在任务教学小组中，每组每个人各分配自己的任务，比如在数字这块，有找数字的，有说的，任务相互关联，层层递进，这样要求小组间的合作必须紧密团结，流畅，使得教学环节有序进行， 同时小组长必须密切配合老师及分配任务给其他同学。提高学生们的合作探究能力，展示能力，但在教学流程中不免出现意外情况，比如学生的胆怯忸怩，这要求教师要有足够的耐心，亲和力，鼓励更多学生积极参与，合作学习，重视学生的课外任务，设计同时更注重活动，体验用英语解决问题的成就感，学生在自身素质方面还需有所提高。在任务型教学中每个环节需完美无缺才能有好的效果，在生本教育这片领土我们还需做很大的努力，做到最大限度提高。
