5、总结收获
让学生总结本节课的收获。
6、布置预习
预习Unit1并找出疑难问题。
【板书设计】The Object Clause 宾语从句
引导词 1. 当从句为陈述句时用, 连词 that 引导2. 当从句为一般疑问句时用, if / whether (但whether可以与or not连用, if不能)3. 当从句为特殊疑问句时, 用when, where, how, why, who, what 等疑问词引导.
时态 1. 主句现在时, 从句可用任何时态。2. 主句过去时,从句要改用相对应的过去某种时态。但客观事实、真理仍用一般现在时； Could you tell me. . . 只是委婉的“请求” ，并不表示过去时，所以其后的宾语从句可根据需要用任何时态。
语序 不管是一般疑问句还是特殊疑问句,宾语从句都要用 陈述句语序 (既 主 - 谓 -宾 ).
【作业设计】专项练习。把下列两个简单句合并为一句。

【教学后记】
学生在本节课还是通过几个任务体验了宾语从句，尤其是生生的相互学习，相互教授，比教师主讲这个知识点，取得的效果更为明显。让每个学生都积极在课堂思考，讨论，应该能很好地促进学习。在教学过程的调控上，应注意教学的有效性，在实施过程中一定要考虑学生的实际情况，多了解学生掌握宾语从句的现状，给与学生更明确的学习指导，那学生对这个知识点就会掌握得较好。
