教学过程：

一、Pre-class

1. Greeting

2. Leading-in

学生活动：（1）学生在老师的引导下复习本节课的单词，并完成活动1中的练习。通过英文释义和句子重构加深对所学词汇的理解。学生根据英文释义从Reading and Thinking板块的语篇中找出对应的词汇进行替换。教师重点解释第五句。其中charge是熟词生义，presume是非课标词。该句包含主语从句、省略句和状语从句。

（2）学生利用活动1中的词汇回答问题，既回顾了小说情节，又在语境中运用了词汇。

Why did Claire begin to trust Tony?

What do you think is the most important factor that helps you to earn people's trust?

 (Tony always treated Claire with dignity, and she gradually admired his wisdom and integrity. Therefore, she began to trust him. For me, those who are honest and sincere are more likely to win my trust. )

Why do you think though it was completely innocent, Claire still felt guilty when she was discovered by Gladys? (Obviously, Claire was innocent of cheating on her husband, yet she did follow all Tony's instructions and tend to rely on him emotionally, which showed that her attitude and feelings changed greatly. I believe that's why she felt guilty somehow. )

二、     While-class

（1）学生活动：学生完成活动2及补充的翻译练习，通过释义辨析词义。学生完成活动2，辨析词义，匹配释义。教师利用字典、报纸等提供相应语境或例句。学生进行翻译，在理解的基础上辨析词义。

Tourism is critical to the area, for it is a major source of income.

According to the latest policy, children and senior citizens travel at half fare.

Working at the coal mine, he received his wage on Fridays.

At the end of year, you are to receive a Christmas bonus ranging from $50 to $100.
（2）学生完成活动3,在语篇中综合运用所学单词和词块。学生阅读语篇，获取主旨大意。学生再次阅读语篇，完成填空，结对核对答案。学生判断语篇作者的观点态度，并使用相关词汇表达个人观点。教师可以在此提问，引导学生思考人类对机器人或人工智能的态度，为单元项目活动的产出作铺垫。

How do people feel about AI robots looking more like a human than a machine?

What are people's attitudes towards more and more intelligent robots?

Do you agree that Sophia should be given citizenship? Why or Why not?

（3）学生完成Review useful structures 部分的活动1，找出句子中的被动语态。

Answers: was going to be tested out; to be harmed; was being looked after; was being offered; was not allowed; was being treated badly; to be discovered by her; was being completely transformed
老师可以提问学生：why is the passive voice used？

The passive voice is used to focus on the person or object that experiences an action rather than the person or object that performs the action. It is used when we don't know the performer, or the performer is unimportant (and therefore omitted), or the performer is to be highlighted (and therefore placed toward the end).

（4）学生完成Review useful structures 部分的活动2， 在具体的语境中使用被动语态。完成练习后，师生核对答案，学生翻译句子。

1 be undone 木已成舟。

2 was elected 珍妮特上个月当选为学生会主席。

3 be added 蛋糕料里需要加入两百克面粉。

4 was built/will be built一个拥有三千座位，供马戏表演使用的场地于十一月建成／将在十一月建成。

5 has been improved 自从采用了新软件，工作效率就被提升了。

6 is allowed 经济舱的乘客每人仅允许携带一件随身行李。

7 be invited 我很荣幸能被邀请在AI大会上发言。

8 was being discussed 我进会议室的时候发现正在讨论销售员的薪水。

9 be admitted 使用转换为盲文的高考试卷，一位高中的视障学生考取了630分（总分650）。他有望被一所名校录取。
（5）学生完成活动3，体会被动语态在图书简介中的语用功能。

Answers：

is regarded; explored/represented; written; was translated; represents; is recruited; has been set up; gets caught up; connected; be discovered

学生完成填空。教师通过提问、复述来检查学生对句子的理解，并强调核心动词的用法。需要特别关注的是第一段的首句和结尾句。前者结构相对复杂，涉及被动语态、主语补足语、定语从句；后者的核心动词explore在具体语境中的含义与学生平常熟悉的词义有差别。

学生再次阅读语篇，根据语篇类型，分析作者的写作目的和写作逻辑。

Why does the author write this passage? How does he/she convey his/her purpose?

The passage is a book introduction to the sci-fi novel The Three-Body Problem, written by Chinese writer

Liu Cixin. With The Three-Body Problem, the writer intends to tell us how our future can be freely imagined and represented in science fiction.

The first paragraph tells about the book's writer and translator and introduces its influence and achievement. The second paragraph contains a very brief summary of the book's beginning, which is aimed to arouse readers' curiosity.

三、After-class

学生阅读练习册Using Structures板块中活动3里的语篇，归纳优秀的图书简介所具备的优点以及行文特点（被动语态）。教师可提问：

After reading the two book introductions, do you want to read the book? Why or why not? What are the good qualities represented in these introductions?

四、   Summary

老师根据课堂内容，总结课上所学语法。

现在完成进行时

现在完成进行时与现在完成时的区别

现在完成时强调的是某个刚刚完成的动作或某个过去的动作对现在的影响或产生的结果；现在完成进行时则强调动作的延续性。

五、作业布置：布置学生课后完成练习册第83页的活动2,以巩固课堂所学，同时让他们结合语境体会不同时态在表意功能和用法上的差异。
