Unit3 Discovering Useful Structures名师教学设计
课时内容
Talk about something that has been done
主题语境: 人与社会
主题群: 科学与技术
子主题: 科技发展与信息技术创新
语篇类型: 文字、练习
文本分析:
本节课设计了三个部分，第一部分比较现在完成时主动语态和被动语态的区别，第二部分把主动语态变成被动语态，第三部分是读一首含有现在完成时被动语态的诗歌，并尝试写一首含有现在完成时被动语态的诗歌。针对文本练习设置少，教师应补充适当练习以帮助学生理解和掌握现在完成时被动语态的用法。
课时目标
1. 学习现在完成时的被动语态。
2. 提高语法的实践运用能力。
重点难点
重点:
对现在完成时被动语态的理解。
难点:
尝试使用现在完成时的被动语态写一首诗歌。
教学准备
教师准备:
现在完成时被动语态的相关练习。
学生准备:
预习现在完成时被动语态的用法。
教学过程
Step I 学习理解
活动一: 情境导入（Guessing game)
Ask students to guess what has been changed in the classroom
(1)The lights___________________________________
(2)The blackboard___________________________________

(1)The lights have been turned off.
(2)The blackboard has been cleaned.
(3)The door has been closed.
(4)The windows have been opened.
(5)The floor has been cleaned.
活动二:识别时态（SB, P30, Part 1)
Read the pairs of sentences. Underline and compare the different verb forms.
Jan’s life has been greatly improved by the Internet.
Much has been written about the wonders of the World Wide Web.
The Internet has greatly improved Jan’s life.
People have written much about the wonders of the World Wide Web.
现在完成时的被动语态表示动作发生在过去，到现在已经完成或对现在仍有影响，其构成是: have/has been + done。例如:
The computers have been used in communication, finance and trade.
The computers have been put into robots.
It has been used to make mobile phones as well as help with medical operations.
活动三: 控制性练习（SB，P30，Part 2)
1. Go through the sentences and make sure students understand their meanings.
2. Ask students to change the sentences into the present perfect passive voice according to the example.
EXAMPLE
They’ve built a kind of new PC with more functions.
A kind of new PC has been built with more functions.
Suggested answers:
(1) The software has been downloaded to help my phone battery last longer.
(2) An identity card has been lost by someone.
(3) Has the Wi-Fi password been confirmed
(4) Has the button been pressed yet to copy the file
(5) Has a comment about the online database been made

活动四: 情境练习
Show some pictures and ask students to make more sentences with the present perfect passive voice.
Situation 1:
Suggested answer:
More new buildings have been set up.
Situation 2:
Suggested answer:
More trees have been planted.
Situation 3:
Suggested answer:
The old computer has been replaced.
【设计意图】在对现在完成时的被动语态有了初步了解和认识之后，提供语境，让学生学会运用，加深理解，提高学生在语境中使用时态的能力。
Step III 迁移创新
活动五:语境中应用时态（SB，P30，Part 3)
l. Read the poem.
Look at the way your face has been washed
Look at the way your teeth have been brushed
Look at the way your shoes have been cleaned
You’d better do them again.
Look at the way the flowers have been planted
Look at the way the grass has been cut
Look at the way the paths have been swept
I hope that you’ll come here again.
2. Then think of your own situation and write a similar poem.
【设计意图】通过朗读含有现在完成时被动语态的诗歌，把学生置入新的语境中学习时态，然后让学生发挥想象力，写出相似的诗歌，有助于对现在完成时的被动语态有更深刻的理解和更准确的把握。
