教学过程：
Step I Grammar
Present perfect passive——现在完成时的被动语态
【备注】语法知识点讲解详见第二教案“重点语法精讲”。
1.Finish Activity 1 on Page 29 of the textbook.
2.Give enough examples of the usages of present perfect passive.

Keys：
①Many things in our lives have already been affected by it.
②3D-printed hamburgers have been served by some restaurants in London to customers.
③But perhaps the most significant success that has been achieved to date by people is in medicine.
④Human body parts，including a beating heart have been made with 3D printing technology.
⑤A new 3D-printed shell has been given by people to a turtle injured in a forest fire.
（2）Ask students to imagine they are Dr Moore. Then look at the pictures on Page 29 and tell the police about the damage and loss to their lab. Use the present perfect passive where appropriate.

1 astronomer 2 biologist 3 geographer 4 physicist
5 chemist 6 mathematician
Step Ⅲ Invention stories
1.Read “Did You know ” and learn about things about Alzheimer’s disease.
2.Finish Activity 7&8 on Page 31.
（1）Listen to the conversation and number the pictures in the correct order.
（2）Listen again and complete the notes.

【设计意图】该部分学习基本按照课本设置的顺序来完成，由浅入深，逐层加深难度，锻炼了学生读、听、写、说的能力。通过读“Did You know？”部分，了解阿尔茨海默病，然后通过听录音，先解决浅层的理解，再记录听力的要点，完成 Activity7和 Activity8。接下来是说的环节，通过语言输入，学生掌握相关词汇和句式，在此基础上做对话练习。整个环节内容不多，但环环相扣，遵循了语言的认知规律，设置科学、合理。
Step IV Summing up
总结现在完成时的被动语态的含义和用法，并注意该部分新学词汇的运用。
Step V Homework
1. Give students some examples to fill in the blanks with the present perfect passive.
2.Master the usages of the new vocabulary.
