A. Reading
1. Look at some pictures of endangered animals and ask them to answer the following questions.
(1) Do you know these animals
(2) What do they have in common
Yes, South China tiger, whales, Tibetan antelope [t betn nt l p]
They are all endangered. They are close to extinction.
(3) Why are they close to extinction
2. Finish part A on page 8.
A. Jim is reading a news report about how human activities are harming animals. Read the news report and answer the questions below.
Because of natural disasters, human activities ...
Human activities cause
increasing harm to animals
When you think of a fearsome(可怕的;骇人的;令人生畏的) hunter, images of lions and sharks may spring to mind. Recent research by environmental scientists, however, shows that in fact, humans are the most fearsome hunters who have the greatest impact on animal populations.
-some
A. (构成形容词) 引起（或易于）…的
troublesome 令人烦恼的，讨厌的quarrelsome爱争吵
B. (构成名词) 人（或…个）一组

Human activities have brought (使处于某种状况；使到某地) many animals close to extinction. In the last 500 years, over 300 species of animals have gone extinct. Some activities, such as hunting and fishing, directly harm animals, while other activities, such as development in towns and cities, impact indirectly on animal populations.
Hunting and fishing have directly influenced the world’s animal populations. Some people hunt animals for food: whale meat is eaten in some parts of the world. Some people hunt animals for fashion: animal skin is used to make coats and bags. Still others hunt animals just for fun: deer are tracked and shot by people who enjoy the excitement of the sport.
Human activities that have indirect effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with nowhere to live, or no food to eat. We can also put animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and damaging influence quite far from their source. 空气、水、噪音和光污染都能对远离源头的地方产生深远的破坏性影响。
Partly due to pollution caused by ship traffic and other human activities, the dolphin population has dropped greatly. △ As the human population continues to grow, so does the effect we have on animals.
“ so + 助动词 / 情态动词 / 系动词 + 主语”: 句中 so 表示前者的情况同样适用于后者。
如：
As the demand for products rises, so ____ their prices. 随着对产品需求的增加，其价格也会上涨。
I went there yesterday. So _____ she.
—My daughter's been practicing jazz dance for two years.
—Oh, really So ______ mine.

People cutting down trees.
We will be better able to change our behaviour.
2. Finish B2 on page 9.
B2. Watch the video again and complete the notes below.
beautiful and lively
food and medicine
maintaining the balance
against the law
animal habitats
using less paper
Video script
Narrator [n re t (r)]: Today I want to talk about protecting animals. We often forget how important animals are to our world. They make our world more beautiful and lively. They provide food and medicine for us. They play a role in maintaining the balance of our ecosystem. It’s therefore our duty to protect animals.
The best way to protect animals is to do what many countries did with whales years ago. When several whale species were hunted near to extinction in the last century, many countries made killing whales against the law. If we make it against the law to hunt endangered animals, populations of these animals will have time to recover.
We must also try to protect animal habitats. Creating protected areas is an effective way to protect animal habitats. Well-planned and well-managed protected areas can ensure that water and food supplies are safe, and can reduce the impact of human activities. There are also things we can do to help protect animal habitats, and even a small action can make a big difference.
For example, using less paper may not seem like it would save the animals in the Amazon rainforest. Yet since the loss of animal habitats is partly caused by people cutting down trees in the rainforest, to a certain degree, reducing the need for paper helps protect animal habitats from destruction.
Finally, making people understand the problems facing animals also helps. The more we learn about how human activities harm the environment, the better we’ll be able to change our behaviour—before it’s too late以免为时过晚!
C. Speaking
1. Provide more information on the topic of animal protection by filling in the following table.
Why to protect animals Why are animals endangered How to protect animals
They help maintain our ecosystem. Hunting and fishing Create protected areas.
They provide us with food and
clothes.
They bring us fun.
They lead us to key advances

Cutting down trees
Agriculture
Cut down fewer trees.
Use little paper.
Raise people’s awareness of protecting animals.

Possible answer
A: I read a news report that animals, especially wild ones, are at risk when we don’t see them as important to our world. Do you think we should protect animals and their habitats
B: Yes, it’s of great importance because they help maintain the balance of our ecosystem. They provide us with many things such as food, clothes and happiness.
A: You’re right. Don’t forget they’ve also led us to key advances in science and technology.(引领我们在科学和技术方面取得了重大进展) Unfortunately, some human activities have done much harm to them, directly and indirectly.
B: What do you mean
A: For example, hunting and fishing directly cause animal populations to fall, while indirectly, the cutting down of trees leads to the loss of animal habitats.
B: That’s true, but we can take measures to help save them.
A: Definitely! What do you suggest
B: We can reduce how much beef we eat because forests are often cut down to make room for cattle farming and can also reduce our use of wood and paper. Most importantly, we should call on people to pay attention before it’s too late. What do you think
A: Agreed! Writing an article about it for the school newspaper is a good way to start!
D. Writing
1. Write an article for the school newspaper calling for everyone to protect animals. Use your ideas from part C and the information in parts A and B to help you.
Finish the article individually. You can refer to “Planning your writing” in part D on page 10 to help their writing in terms of the structure and language.
Planning your writing
Learning about the structure
When you write an article to call for the protection of animals, you can follow the structure below:
State the importance of protecting animals.
Explain how human activities harm animals.
Come up with ways to protect animals.
Learning about the language
It is a good idea to give examples when you explain how human activities harm animals.
You can use the following expressions: for example, for instance, take the example of, etc.
You can also use powerful and emotive (引起强烈情感的;令人情绪激动的) words and phrases to make a strong impact on the reader.
2. Check your writing after you finish and exchange drafts with your partners for peer review.
Checking your writing
Remember to check your writing after you finish and exchange drafts between you and your partner. Pay attention to the following aspects:
3. Share your article in class and evaluate which one is most reasonable and appealing.
Possible answer
Help protect animals!
Animals are very important to our world, and we must work together to protect them. Some of them bring us joy. Some provide us with food and clothes.
Still others have led us to key advances in science and technology. Last but not least, animals help maintain the balance of our ecosystem. Unfortunately, many species are endangered because of us.
Human activities have done much harm to animals. Some human activities, such as hunting and fishing, directly cause populations of many animals to fall. Other human activities
have an indirect impact on animals. For example, the destruction of the Amazon rainforest has led to the loss of animal habitats.
We must try to do whatever we can to protect animals. By reducing our use of wood and paper, we can save not only trees, but animals living in the forests. Likewise, we should try to reduce the amount of beef that we eat, because
many trees in the Amazon are cut down to make room for cattle farming. But above all, we should spread awareness about the importance of animals and their need for protection我们应该宣传动物的重要性和保护动物的必要性.
