Learning about Language国家优质课一等奖

教材内容分析：Learning about language 分为词汇（Discovering useful words and expressions）和语法（Discovering useful structures）两大部分。Discovering useful words and expressions第一题

根据单词释义写出相对应的词汇，考查学生对Reading Who Am I 文章中的重要词汇及短语的理解。第二题是对短文填词的形式，考查学生对几个重点单词在篇章中的运用。Discovering useful structures是学习现在完成时的被动语态。第一题是根据文章中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。第二题是根据例句把所给的现在完成时的句子变成被动语态。第三题通过欣赏一首小诗理解现在完成时的被动语态的用法。

学情分析：，学生已经在阅读课上初步认识了部分词汇，但仅仅停留在汉语认知，希望通过本节课让学生逐渐建立用英语来解释英语单词的意识，更深刻的理解英语单词的意思和用法。现在完成时在初中也接触过，但被动语态对学生来说仍是难点，因此通过本节课的大量练习，学生能深刻认识现在完成时的被动语态，并尝试使用现在完成时的被动语态。

2. 掌握现在完成时的被动语态

Discovering useful structures:

The Present Perfect Passive Voice

Step1. Give the students some sentences from reading part and read them. 1.Over time I have been changed quite a lot.

2.First as a PC (personal computer) and then as a laptop，I have been used in offices and homes since the 1970s.

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

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

5.I

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

Step2 Elicit the structures:S+ have / has + been + V-ed The passive voice is used when the subject of a sentence is the person or thing affected by the action of the sentence. We particular use the passive voice when we don’t know who has done something. 现在完成时被动语态的肯定式为：

have / has + been + done eg. The experiment has been done successfully.

现在完成时被动语态的否定式为：

eg. have / has + not + been + done Tom’s novel has not been published.

现在完成时被动语态的一般疑问句需将have / has提到主语的前面。

eg.Has his bike been repaired?

现在完成时被动语态的特殊疑问句为：疑问词

+ have / has + been + done

eg.Who has been invited?
