1. 教材分析

本单元以computers为话题，旨在通过单元教学，综合听、说、读、写等多种形式，使学生了解计算机和信息技术的产生和发展过程及其在我们的学习、工作、娱乐等生活中所起的重要作用，激发学生对信息技术的兴趣。

Learning about language分词汇（Discovering useful words and expressions）和语法（Discovering useful structures）两大部分。本节课是第二课时Discovering useful structures，内容是学习现在完成时的被动语态。教材中共有三个任务：1是让学生根据例子提示在本单元阅读课文中找出两个以上含有现在完成时的被动语态的句子，初步了解这一时态的形式；2是根据例句提示把所给的现在完成时句子变为被动语态；3通过欣赏一首小诗进一步理解现在完成时的被动语态的用法。

2.学情分析

我校为F类生源学校，高一（2）班是理科普通班，男生居多，学生英语基础较差，但是思维非常活跃，在老师的带动下，学习英语的积极性有所提高。语法是学生最头痛的问题之一，在本节课中，教师将课本中的材料进行了删减和改编，使之适合于学生现有的水平，整

堂课将采用“问题导学”式教学方法，在每个环节均设计了问题或任务，引发学生自主思考和探究本节课的语法知识点——现在完成时的被动语态。因为是理科班的学生，教师特意设计使用了类似数学公式推导法来帮助学生推导出现在完成时的被动语态的完整结构，而不是直接呈现，力求帮助学生更好地理解这一复杂的语法现象。

Step 1: Revision and lead-in 1.Question：Do you know these new inventions of computer?

2. Show some pictures and ask the Ss to distinguish different types of computers and make some sentences, using the Present Perfect Passive Voice.

A wrist-worn PC has been invented recently. A pen-like computer has already been developed.

Step2: Discovering

Question：Can you pick out more than 2 sentences in the Present Perfect Passive Voice from the reading passage?

1. Ask the Ss to pick out more than 2 sentences in the Present Perfect Passive Voice from the reading passage and discover whether these sentences have something in common. 1）I have been used in offices and homes since the 1970s.

2）Over time my memory has developed so much that, like an elephant, I never forget anything I have been told!

3）Since the 1970s many new applications have been found for me.

4）I have also been put into robots and used to make mobile phones as well as help with medical operations.

5）

I have even been put into space rockets and sent to explore the Moon and Mars.

2. Study these sentences carefully and sum up the form of Present Perfect Passive Voice tense. Elicit the structure: S + have/has + been + V-ed 3. Question: Why is the passive voice used here?

Step3: Discussion: learning the structure 1. Question:

What’s the difference between the Present Perfect Tense and the Present Perfect Passive Voice?

现在完成时

主动语态

have/has done 现在完成时

被动语态

have/has been done 2. Questions: When do we usually use passive voice?

When do we use has and when do we use have?

3. Let the Ss discuss and give some explanations. T: The passive voice is used when the subject of a sentence is the person

or thing affected by the action of the sentence. We particularly use the passive voice when don’t know or aren’t bothered exactly who has done something. We use has when the recipient of the action is the third person single or single nouns. We use have when the recipient of the action is the first or second person or plural nouns.

Teaching Reflection 课后反思

考虑到学生的实际情况，此节语法课设计较为简单，没有罗列复杂的语法规则，我淡化了对语法规则的讲解，引导学生从观察例句到总结规律再到练习实践，构建了阶梯性的任务链，强调语法规则在真实情境中的运用。我创造性地使用了类似数学公式推导的办法来帮助学生理解现在完成时的被动语态这个语法点，学生接受度较高。我试图改变陈旧的语法教学模式，用“问题导学”教学法来串联整个课堂，气氛较为活跃。既不脱离教材，又不局限于教材，特别关注了学生的语言运用能力，选择了学生熟悉的场景来造句，学生普遍感觉较为容易。最后的输出部分——创作小诗歌，学生参与度较高。本节课教学目标达成度较高，突破了重难点，学生享受到了学习的乐趣。接下来可以继续研究如何更好地运用“问题导学”教学法来进行其他课型的教学。
