Human activities have brought many animals close to extinction.
Hunting and fishing have directly influenced the world’s animal populations.
Human activities that have indirect effects on animals can be just as harmful.
1.What are the three main reasons why people hunt animals
Reading part A--Questions
2.How do human activities have effects on animals indirectly
Step 2 Reading
1.What are the three main reasons why people hunt animals
Some people hunt animals for food; some people hunt animals for fashion; some hunt animals just for fun.
Reading part A--Questions
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.
Step 2 Reading
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 nohere 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. 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.
Reading part A--Questions
2.How do human activities have effects on animals indirectly
When farms and factories are built, human activities put animals in danger by destroying their habitats and their food sources. What’s more, the populations of some animals have dropped greatly because of the pollution caused by human activities.
Step 2 Reading
Step3 Retell the key points of the news report.
Human activities have brought many animals close to extinction.
Thesis statement:
Deduction:
Impacts on animals due to human activities
Direct
Due to building farms or factories, animals’ habitats or food sources are destroyed.
Air, water, noise and light pollution can all have an impact on animals.
Indirect
For food
For fashion
For fun

Read the questions in part B1 on page 9, and make some reasonable predictions about the answers.
Focus on key words
Do not try to catch every word. Instead, listen for key words and phrases. You should focus on getting the main idea, not on single words or grammar.

Video Part B 2
②
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!

Tips 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 words and phrases to make a strong impact on the reader.
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.
Help protect animals!
