◆ 内容分析
本板块围绕单元话题，要求综合单元所学，在小组合作中用英语来制作一本关于环境问题的小册子。教学活动首先讨论现存的各种环境问题，然后以小组为单位，自主选择一个感兴趣的研究话题，再参照所给范例，从“原因”“后果” “控制方案”三个方面来完成小组的探究任务。
在制作过程中，从网站或其他渠道收集相关素材，丰富内容。制作完成后以小组为单位，分别展示成果，并用英语对其进行介绍。最后将各小组的内容页面合并，形成以“环境问题”为主题的一本完整小册子。
◆ 教学目标
By the end of this section, we will be able to:
1. use effective communication skills when interacting with others;
2. collect and sort the material needed when making the booklet;
3. present the outcome of group work;
4. evaluate and comment on each other’s works.
A. 准备
1. Review the words and expressions related to the topic of environmental problems in this unit.
polluted our soils and seas
cut down too many trees
Over the past 50 years, about 17 per cent of the rainforest has disappeared due to human activities such as agriculture and cattle farming.
When the water goes away, it takes
away the nutrients in the soil.
Global warming, for example, is a major problem caused by greenhouse gases. It may lead to extreme weather events: droughts, heatwaves and so on.
Human activities have brought many animals close to extinction.
Hunting and fishing have directly influenced the world’s animal populations.
When we build farms or factories, we destroy animal habitats and leave many animals with nowhere to live, or no food to eat.
Air, water, noise and light pollution can all have a deep and damaging influence quite far from their source.
The river is dirty and smelly. The smog in the air has coloured the sky a smoky grey.

2. Go through part A on page 13 and ask them to list more environmental problems they know of.
As a class, discuss different environmental problems. You can use the ideas below or think of other ideas. Then in groups, choose one problem to research.
air pollution noise pollution
habitat loss light pollution
water pollution global warming
soil pollution overfishing ...
3. Learn the tip of “Interacting with others” in part A, and use it to discuss in groups the topic they would like to choose.
Tip: Interacting with others
While discussing in a group, make eye contact with others to make sure that they can understand and are interested.
Listen to their feedback carefully and respond appropriately. You may also ask questions to show that you are interested.
B. 实施
1. Research your chosen topic, collect useful information and decide what information should be included in the booklet by answering the following questions.
(1) What topic will you choose to research
(2) Why do you choose this topic
We will choose global warming as our topic.
We choose to research the topic of endangered animals.
I was shocked when I was watching a TV programme about global warming since it has greatly affected our planet.
I read a news report and got to know that animals, especially wild animals, are at risk. I think animals are important to us and we should protect animals and their habitats.
(3) How will you research your chosen topic
2. As a group, research your chosen problem. Use the diagram below to help you.
We will surf the Internet and collect useful information. We will use the diagram in part B to help us.
What aspects of information should you cover
Causes
Consequences
Control
Let's take water pollution as an example.
3. Study the example below .
Water pollution
Causes
There are various causes of water pollution. Large amounts of industrial waste poison[破坏，污染(水、空气或土地)] the water after they enter water bodies. Moreover, animal and human waste pollutes the water. Water pollution is also caused by poisonous chemicals used in agriculture.
Consequences
Polluted water bodies not only do harm to animals and plants; they also have a long-lasting effect on humans. For example, in many parts of the world, the poor quality of the local drinking water gives rise to public health problems.

Control
To prevent further damage to water bodies, it is necessary to take some measures. First, we must draw public attention to the problem. Second, more strict laws should be passed to help reduce water pollution. Third, we can volunteer to take part in clean-up activities.
4. Study more about the sample in the textbook by answering the following questions.
(1) What is the sample booklet page about
It is about water pollution.

Draw public attention to the problem; Pass more strict laws; Take part in clean-up activities voluntarily.
6. Proofread(校阅；校对；勘校) the booklet page to make sure the language is correct and add related photos or illustrations if necessary.

Further study
“My Wish: Build the Encyclopedia of Life” 《我的愿望：打造生命的百科全书》 is a video talk(视频演讲) given by biologist Edward O. Wilson. In the talk, he comes up with the idea for collecting data about every species living on the Earth. He believes that we can understand and manage the Earth’s biodiversity better by exploring it properly. Watch the video talk to find out why this project is important to us all.
