一课设计之 Unit13 We’re trying to save the earth!
Section A Save the sharks. 3a-3b
课程简介：
Unit13 We’re trying to save the earth.出自人教版九年级全一册， 围绕环境保护的话题，展开环境污染与保护的讨论，引导学生复习初中所学关键句型，重点突破被动语态，现在进行时，现在完成时与情态动词。所执教的班级学生基础较为薄弱，但学习英语兴趣较为浓厚。由于本课时是本单元的第二课时，在本课学习之前，学生已经掌握部分相关的词汇和短语，并已复习过本单元要求的几个语法点（现现在完成时、被动语态和情态动词的使用），对于他们阅读文章具有铺垫作用；其次，学生已升入初三，具备一定的英语阅读能力和阅读技巧。最后，本课时的话题——“保护动物”贴近生活，学生很容易接受，最终达成保护环境就是保护我们自己的情感目标。
本节课是一节阅读课，主题是“保护濒危动物”。3a的阅读是一篇倡议书，其中以鱼翅汤为切入点，介绍了鱼翅汤制作对鲨鱼的迫害和对生态平衡的破坏，引起学生的共鸣，呼吁保护鲨鱼。文章使用了多种时态和句型，需要学生掌握相关语法，理解文章大意并抓住细节，同时复习连词的运用。教学步骤中设计了思维导图，回答问题，填写表格，小组展示与pk朗读，迁移写作等教学活动，且帮助学生在阅读输入后进行有效的输出训练制作倡议书号召保护濒危动物，是对语言点的有效复习与巩固，更是对学生情感目标的落实与升华。

Step 1：Warming-up
Play a game.
Before the game, the teacher says:
Before the class, let’s play a game. I will give you some key words and you will have to tell the other students something about me as soon as possible. Let’s have a try.
S1: Miss Liu is from Hubei province.
T: Yes, you are right.
S2: Miss Liu loves elephants best.
...
设计意图：在游戏中自然进入教学氛围，帮助学生打开英语思维，打破师生间的壁垒，增强课堂互动。
Step 2: Leading in
Show the pictures of some animals and their fur or bones.
While watching, the teacher says:
Do you know these animals ( The teacher shows pictures of the animals)
Are their numbers going up or down
Why
Because of these. ( The teacher shows the pictures of tiger bones and fur, elephant ivory and so on. )
So these are all endangered animals. Do you know some others
S1: Pandas.
S2: Whales.
S: Sharks.
...
Show pictures of sharks and encourage students to talk about sharks.
A possible conversation between the teacher and a student:
T: Do you like sharks
S: No, I don’t
T: Why
S: Because they look cruel.
T: What else do you know about sharks
S: They are strong and they eat people....
设计意图：创设情境，切入主题。通过学生熟悉和认同的濒危动物引入话题，在谈论对答鲨鱼的看法中激活学生的已有认知，活跃学生的思维，为下一步教学活动做好铺垫。
Step 2：Pre-reading
Get students to learn some new words and expressions about sharks.
The teacher tells students:
These are the shark fins( pointing to the fins in the pictures of sharks. Without fins, they can’t swim and they will die soon.
Sharks eat fish and fish eat sea plants. This makes up the make chain. Sharks are at the top of the food chain. Different food chains make up ecosystem.
Some people think that sharks are cruel because they eat people. In fact, there are some misunderstandings about sharks.
Play a video and get students to know the misunderstandings about sharks.
The teacher plays a video and asks students to answer two questions after watching it:
Q1: Are sharks cruel ( No, they are shy.)
Q2:Should we be friendly to sharks and save them
Yes. Sharks are in danger. If we don’t save them, they will disappear soon.
No. Sharks are cruel and dangerous. They even kill people . They are very strong. So there is no need to save them. ( Choose A. )
设计意图：读前活动，通过谈论鲨鱼的相关知识来帮助学生在头脑中构建与话题相关的词汇体系，同时激活对于鲨鱼这个话题的已有认知，纠正其中的错误观点，为即将阅读到的人类因鱼翅而捕食鲨鱼导致鲨鱼数量锐减和破坏生态平衡的内容做好铺垫。
Step 3：While-reading
Skimming
1). Enable students to skim and get one detail about sharks.
The teacher asks:
How many sharks are caught and traded every year
( 70 million. That is 70,000,000, a large number.)
Can you read and find the specific information as soon as possible.
Come on! You can make it!
Scanning
1). Get students to scan and match the paragraphs with the main ideas in 2 minutes.
Paragraph 1 Let’s stop eating shark fins and save sharks.
Paragraph 2 An introduction of shark fin soup.
Paragraph 3 Finning is not only cruel but also harmful to the environment.
2). After two minutes, ask students to check answers in groups:
Paragraph 1 Let’s stop shark fins and save sharks.
Paragraph 2 An introduction of shark fin soup.
Paragraph 3 Finning is not only cruel but also harmful to the environment.
Careful reading
. Stimulate students to read Paragraph 1 and answer:

What have they done
. Lead students to talk about shark fin soup.
The teacher tells students:
Shark fin soup is made from shark fins. It is rare and believed to have many health benefits, so it is very popular and expensive. In fact, it is less nutritious than an egg.
. Make students read the article aloud.
设计意图：读中活动，先让学生略读文章，找出每年被捕杀鲨鱼的数量，大致了解鲨鱼的生存现状。然后扫读文章，将段落与其主旨大意连线，了解文章结构，即提出问题然后分析问题最后倡议停止食用鱼翅保护鲨鱼解决问题。接下来，逐段阅读，通过分段阅读后回答问题，完成思维导图，填写表格等教学过程，有效地引导学生抓住各段落的主要信息，学会关注篇章中的重点词汇和句式结构，强化学生的记忆。另外，视频的插入更加深了学生对于文章内容的理解以及思想情感上的共鸣。最后带着这样的理解和共鸣，学生再大声朗读文章，温故而知新，一定有新的体会，同时也为后面的语言输出环节做好准备。

2)The teacher can explain the task and give some advice:
Ask other groups to show at the front and invite other groups to give evaluations.
Evaluations
Pronunciation & intonation 发音 excellentgoodfair（一般）
Information 信息
Group work 合作
设计意图：通过保护动物的公益广告号召同学们将视野扩大到更多濒危动物，然后小组合作选定倡议保护的动物，利用本节课学到的关键词句仿写文章完成倡议书，号召更多人去保护更多动物。本环节为学生提供了语言输出的机会。小组展示期间，其他小组也要就这个组成员的语音语调、内容形式、小组合作等方式进行评价，以增强学生的参与意识。
Step 5. Assign
Design a poster to call on people to save one kind of endangered animals.
设计意图：将话题拓展到用其他表达形式，让学生有机会整理思路，根据自己对保护濒危动物的理解，设计自己的海报，提升学生应用文的阅读能力。
