一、教材分析

本节课的授课内容为被动语态中的一个重点也是难点的内容：现在完成时被动语态的学习及其应用。对于该内容学生半知半解，加上语法容易让人觉得枯燥，学生对此内容有排斥畏难心理。所以教学中将语法知识的传授和语言基本技能的学习结合到一起，注重学习语法与语言的运用。采用任务型教学法、情景教学法和小组合作探究学习法，让学生亲身去感知、领悟知识和运用知识，从而扩大课堂的语言输入量及学生的语言输出量，使其内容更加丰富，降低了语法学习的难度，同时也使语言学习和运用语言的过程成为一种栩栩如生的互动体验，提高了学习效率。

二、学情分析

授课对象为高一12班的学生，大部分学生的基础知识仍然较为薄弱，运用英语进行交际活动的能力较差，主动学习的动力不够，然而他们学习比较认真，部分学生的基础较好，能主动配合老师。

三、教学目标

知识与技能：

1.让学生弄清楚现在完成时被动语态的结构和用法；

2.重点是现在完成时被动语态的应用。

过程与方法：

1.培养学生自主学习、协作学习和探究的能力；

2.培养学生分析问题、解决问题、归纳问题的能力。

四、教学重点和难点

现在完成时被动语态的基本构成与实际应用。

五、教学策略和方法

本节课的教学以学生为中心，教师在教学过程中则适时介入，引导、启发、组织、帮助、促进。随堂进行小组指导，一方面参与学生的讨论，更给学生以个别辅导，以帮助学生解决学习过程中的难题。通过演示课件，便于学生对知识的把握，并从中获得启迪，从而解决问题。通过小组协作法分析问题、解决问题，从而内化而形成学习成果，并将其在全班学生中展示，使学生获得成功的喜悦，从而激发学生的后续学习热情。通过任务驱动教学法将所要学习的新知识隐含在语言操练之中，学生通过对呈现的图片进行分析、讨论，并在老师的指

导、帮助下用本节课的语法对图片进行描述，以达到对语法项目的操练。最后通过任务的完成而实现对所学知识的意义建构。
