4、Encourage the students to say out more uses of computers.

设计依据：以图文并茂的形式，教师循序渐进地引导学生问答，把电脑的不同功能灵活地放在句型中操练，帮助学生及时消化巩固所学内容；鼓励学生说出电脑的其它用途，训练学生的扩散性思维。

Step 3：Practice

1、Read Daniel and Simon’s conversation in Part B.

2、Practice in pairs

3、Make up similar dialogues. Replace the underlined words with the students’ own information.

Step 4：Presentation

1、Present some new words and phrases with pictures：television、remote control、channel、Then let the students read and spell these new words.

八、教学反思：

1、课堂开讲方式很重要，好的开头等于成功的一半，导入教学的目的在于激活学会生的学习意识，让学生以积极的心理状态投入到新知识的学习中。

2、教师要根据教学内容合理使用教具，把多媒体、投影仪等电化教学手段与实物图片等传统教具有机结合起来。发挥各种教具的特长，形象直观地呈现抽象的语言要点，学生感知鲜明，印象深刻，便于学生理解和记忆，从而取得良好的教学效果。

3、教师要处理好课堂“预设”和“生成”的关系，重视“生成性”资源的利用，同时注重对教学过程的有效调控。教学目的是让学生理解掌握知识，而不是教师按照自己的设计完成教学步骤，学生已懂的知识教师点到为止，学生不懂的知识，教师要设计形式多样的方式反复巩固，直到学生理解、会运用为止。
