一．教材分析

本单元的中心话题是“Laughter is good for you”, 笑是人类的天性，是人类最美的表情，笑一笑十年少。Reading板块向我们介绍了西方国家盛行的单口喜剧和知名的喜剧演员Billy Crystal。本节课是构建在单元话题基础上的语法复习课第一课时，着重复习非谓语动词在句子当中主语和定语的应用。对于非谓语动词在句子成分中宾语补足语的区别复习，安排在本单元语法课的第二课时。本节课各个教学环节的安排紧扣本单元的话题，始终以单元话题笑为主线，穿插各个课堂任务，将语法知识的传授和语言基本技能的学习结合到一起，注重复习语法与语言的运用。采用任务型教学法和同桌角色扮演对话，小组合作探究学习方法，从而扩大课堂的语言输入量及学生的语言输出量。

二.学情分析

高二学生在第五模块三个单元话题学习的基础上，已经熟悉了非谓语动词的三种形式，能基本说出非谓语动词在句子中可充当的成分。在本节课的复习过程中，结合学生原有的知识掌握水平，巩固基础强化正确使用语法知识，提高学生运用语言的深度和难度。但大部分学生基础知识仍然很薄弱，句子成分判定不清，运用英语进行交际活动的能力较差，主动学习的动力不够。很多学生对单元的话题不熟，Reading学习过的课文也较为陌生，因此我为学生创设的语境都和学生本单元学过的内容有关，使得学生复习非谓语动词应用的同时也加深对本单元话题的熟悉度。

三.教学重难点

1.教学重点：

复习的重点---非谓语动词作主语和定语的区别

2.教学难点：

（1）判断句子的成分和非谓语动词三种形式的选择

（2）用非谓语动词造句子

四. 教学目标

1.

知识目标：

3.

五：教学策略

通过齐读，同桌合作表演对话，小组讨论改写作文等具体形式，创设有利于高中生自我认识，自我反省，自我调节的情境，利用他们自身的自我意识水平对自己的学习进行调节，监控。

六：教学过程

Step1: Greeting and lead in (5min) Text Revision 1. The reading article gives us an introduction to _______ and a famous ________. 2. Text abbreviation: Laughing is good for our health and it’s reported that people laughing a lot live longer. Watching comedies is a good way to provide us with laughter. And stand-up is one of the comedies performed on a stage by a comedian talking straight to the audience.

They are ________, _________, ________ Qs: When to use non-finite verbs in a sentence? Qs: What are the functions of the parts in red? They function as the _________ or _________ in a sentence. 设计说明：

本节课开头以复习Reading板块的内容导入今天非谓语动词的复习。先以提问的方式让学生口头回答出Reading课文大意。然后让学生齐读我特意用非谓语动词改编的课文缩写，学生读完后观察圈出的蓝色动词，让学生回答出这些不同形式的动词被称为什么动词，从而引出今天要复习的非谓语动词，同时让一名学生上黑板写出非谓语动词的三种形式。接下来，学生观察划线的部分在句中充当什么成分，进一步引出今天复习的重点即非谓语动词做主语和定语的运用。

Step2: Tell the differences between infinitive and verb-ing as the subject of a sentence 1.Dialogue practice (work in pairs) (5min) (1)

A: Why are you always laughing?

设计说明：

根据对应的图片，同伴角色扮演操练对话，感受动词不定式和动名词做主语在不同语境中的差异。然后让学生思考对话（2）中动词不定式做主语使得主语比较长时，为了避免句子头重脚轻，更习惯怎样的语言表达习惯，从而引出It 在句首做形式主语的常见的句型，即It takes/took/will take sb some time to…

对话（3）的操练是为了巩固这一句型，加深印象。

(4)

A: What do you think of the crosstalk from Deyun Club B: It is friendly of you to invite me to watch it. It’s quite funny .

(5)

A: Do you wish to be a stand-up comedian? B: I hope so. It’s important for a comedian to think quickly and I need practice a lot. (6)

A: Why are you so upset? B: I have lost a large amount of money. A: It is no use pulling a long face. A man isn’t really poor if he can laugh.

设计说明：

根据展示的图片，同伴角色扮演操练对话（4）和（5），复习It做形式主语常用的另一个重要句型：It is/was + adj+ of sb/for sb to…

在复习这一句型时，为了帮助学生区别of sb 和for sb，

分别给出了两组形容词，男女生分别朗读，在读的过程中区别这两组形容词的差异。然后提出大部分学生的误区：看到It在句首做形式主语，就用动词不定式做真正的主语，然而事实并非如此，从而引出最后一组对话中动名词做真正主语的特殊句式：It is no use +V-ing, 并适当补充常见的It在句首，

V-ing做主语的句式：It is no good/ fun/ a waste of time +Ving，学生齐读纠正语音语调。

2. Sentence Translation (5min) (1) Billy Crystal 真聪明，能够立刻讲出笑话来。（It is + adj + of sb + to …）

____________________________________________________ (2) 看Billy Crystal的喜剧是很有乐趣的。(It is fun + V-ing…)

____________________________________________________ (3) 学好相声表演是件不容易的事情。(It is + adj + for sb + to…)

____________________________________________________ (4) 学习小品（sketch）需要时间和努力。

____________________________________________________ 设计说明：

整体感知完动词不定式和动名词做助于的区别后，学以致用，翻译四句与单元话题密切相关的句子，巩固刚复习的重点，同时在实际的语境中加深对单元话题的熟悉度，为日后相关话题的写作积累语言素材。

Step3 : Tell the differences between the three forms of non-finite verbs as the attributive 1. Phrases Translation.(5min) (1) 舞台上的喜剧表演

3

(6) 让世界各地人开怀大笑的能力

the ability ___________ (amuse) people all over the word. Qs; What are the functions of these non-finite verbs in red ?

They function as ______________ 设计说明：

复习完非谓语动词做主语的重点后，转入到定语的复习。此环节，学生完成短语的翻译，大部分短语来源于Reading课文内容，短语（1）是对Reading课文中的语句的改编。完成后让一竖排学生按顺序朗读翻译好的短语，教师帮其纠正错误，关注学生单词的发音，鼓励声音小的学生。读完后，找一名学生判断非谓语动词在翻译的短语中充当的成分。

2. Find out the non-finite verbs as attributive in each sentence

(5min) (1) I have a circus to watch tonight. (2) The stand-up show to be held tomorrow is called off(取消) (3) The man performing on the stage is a famous comedian. (4) Some comedies being shoot (拍摄) now will be on show by the end of the year.

(5) The comedy films acted by Zhou Xingchi is popular with the young. Summary: 做定语时，

在时态上：动词不定式表示__________________

Verb-ing 表示___________________

Verb-ed表示_____________________

在语态上，动词不定式有____________________

Verb-ing表示____________________

Verb-ed 表示_____________________ 设计说明：

为帮助学生在熟悉的语境中感受非谓语动词做定语的区别，此环节我编写了与单元话题相关的句子，另外选取一竖排学生，一一朗读每句话，并指出句中的非谓语动词。再通过例句的分析，从时态和语态的角度，把握非谓语做定语的区别。

Step4: Consolidation (5min) Exercise on P9 Part A Robert is writing an article about the benefits of laughter. Help him complete the article using the correct forms of the verbs in brackets. Laughter is the greatest medicine. It helps those who cannot work out become fit.

本环节通过篇章填空来巩固今天复习的重点：非谓语动词做主语和定语。学生自己讲解所填写的非谓语动词在句子中的成分，校对完答案后，三大组分别朗读每一段，最后结尾全班齐读。文章素材来源于课本语法，适当进行删减，文章内容是有关笑的好处的文章，前面通对话，短语，句子的操练，现在进行篇章的阅读，使得学生的能力逐步的都提高。

Step5: Usage of non-finite verbs in writing (Group discussion) (12min) Here is an English letter from my class.

There are ten mistakes for us to correct. . Dear Editor, My full name is Li Hua, an exchange student from China. Recently, we’ve had a discussion about whether we should cut down trees for economy. Nowadays, (1)cut down trees has become a problem we has to face. (2)Cut down trees has created some serious problems. Firstly, many people(3) cut down trees want to make more money. It is foolish (4) for them to do that. They should stop do that for our environment. Secondly, (5)cut down trees make any animals homeless. In my opinion, it is important for us (6)protect the trees. On one hand, trees (7) give us oxygen help us breathe. So(8) protect trees is everyone’s duty and (9)protect trees is saving ourselves. On another hand, people (10)cut down trees must be punished.

I am looking forward to your reply.

Yours

Li Hua 1. Preparation: Discuss with your group members and rewrite the ten mistakes with the correct non-finite verbs 2. Presentation: Choose one of your group members to show your work 设计说明：

语言的输入最终还是为了语言的输出，而写作就是检验我们语言输入状况的重要途径。由于学生基础薄弱，短时间内难以写出不同话题的作文，因此我在最后选了一篇我班上一名学生写的一封英文书信，指出了十处错误，都是在句中出现多个谓语动词，这也是很多学生经常犯的错误。并且写作的素材来源于前不久刚结束的期中考试试卷中的作文，学生记忆犹新。通过小组的讨论，结合今天课上复习的重点，订正这十处错误。组内成员达成一致意见后，派出代表黑板演示。此环节，通过成员之间的互补互助，发现自身的不足，引以为戒，不再犯同样的错误。

Step6: Summary of the whole class (2min) 设计说明：

师生通过板书一起总结回顾今天复习的重点。

Step7: Homework （1min）

1) Finish exercise C1 on Workbook P98 2) Overview of non-finite verbs as the object complement 设计说明：

课后学生需要通过完成课本后面的练习消化本节课复习的重点，并且复习非谓语动词做宾语补语的应用，为下一课时做准备。
