（一）通过本课教学，我有如下几点反思：
1、结合生物学科进度，点燃学生对cloning克隆的兴趣；体会学科间融会贯通、
相互衔接促进的巨大实用意义。 备课前，了解学生对克隆的认识与知识储备，得知生物学科正好同步讲了“克隆”，我顿时轻松了许多。在学生了解课文主题“克隆”这个专业知识的基础上，进行英文讲解、学习，既能极大地调动学生的学习欲望与兴趣，又能更利于学生的吸收，促进学习效率。我深深体会到学科间融会贯通、相互衔接促进的巨大实用意义。
2.创设环节情景，给学生提供尽可能的参与课堂活动和展现自我的机会。
学生充分参与形式多样的学习情景活动,并大胆展示其学习结果，调到了学生的英语学习积极性和主动性。
3.“寓教于乐”促进理解并形成观点。
借助实物导课，抓住学生注意力，引起学生的兴趣，使其自然顺利地进入课堂氛围，为后面的深入了解做好铺垫。授课中采用先分后总的方法，通过多样化的课堂练习巩固学生对课文内容的理解，在理解的基础上展开讨论，帮助学生最终形成自己的观点。让学生在轻松、愉悦、民主的氛围中，获取知识，整个教学遵循“寓教于乐”的原则展开。 4.衔接高考。
结合课堂问题的设置，将阅读理解的具体方法、巧妙技巧渗透其中，促进高二年级学生的阅读理解能力，与高考自然衔接。 （二） 今后指导
1.课堂思路设计一定要符合学生实际能力，达到在有效课堂时间内充分发挥学生潜能，尽量让不同层次学生都有所收获，既全体进步，又促进学生个性发展，进而有效地实现教学目的。
2.课堂形式的设计应该更科学化，既能有效充实课堂内容，又能帮助学生高效获得知识。而不至于因为多媒体的应用干扰了学生的思维，影响了学生注意力的集中程度。因此，必须定准每堂课的教学目标，有针对性的运用多媒体。对于多媒体与课堂教学的整合应在不断的实践中，不断完善，使课堂教学更合理、更科学、更高效。
