9B Module 1 Unit 1 “Saving the Earth” (Post-reading) The greenhouse effectWe are polluting the atmosphere with chemicals---in the form of gases.
These gases, mainly CO2 are produced by burning fuels such as petrol.
These gases keep in too much heat, which causes sea level to rise and flood cities and even whole countries.Damage to the ozone layerOzone forms an essential protective layers around
the Earth．
Without it, the Sun would burns us up.
We are making holes in it mainly by using chemicals called CFCS, Which we use in fridges and spray cans, and to make plastic items such as fast food boxes.Destruction of the forestsDestruction of the forests is the burning and cutting down of the forests.
It’s making the greenhouse effect worse because trees take in CO2.
It also causes soil erosion and flooding, as well as destroying the homes of people and animals.Bad habitsUsing things once and then throwing them away causes pollution.
This creates massive mountains of rubbish that pollutes our land and sea.
7,000,000,000 drink cans thrown away in Britain each year can reach from the Earth to the Moon.
1. Why is the world in danger?
Because there are various threats to the environment.
2. What is the main gas that pollutes our atmosphere?
CO2 (carbon dioxide)
3. Why is the ozone layer important?
Because it protects us from the Sun.
4. What makes holes in the ozone layer?
Chemicals called CFCs.
5. Why do we use CFCs?
Because they are useful in refrigerators, spray cans and to make plastics.
6. What makes the greenhouse effect worse?
Burning and cutting down trees.
7. What is our worst habit?
Using items once and throwing them away.
8. What is a “green consumer”?
Someone who buys and uses goods that don’t damage the environment. Objective Questions (While-reading) Inference Questions
1. What do the authors want us to imagine?
a) That the atmosphere is made out of glass
b) That the atmosphere is as cold as the moon
c) That the atmosphere is like a greenhouse.
2. What is the difference between the Earth and the moon?
The Earth is warm because it has an atmosphere, but the moon is cold and lifeless.
3. What are the different kinds of pollution discussed in the text?
Air pollution with chemicals like CFCs and gases like CO2, water and land pollution from rubbish.
4. Based on the article, give two specific examples of how you can be a green consumer who buys and uses environmentally safe products.
Don’t use plastic food boxes. Don’t use spray cans. Use regular paint instead of spray paint. Don’t use things only once. Reuse items as much as possible.
5. Does Tony Ma, the reviewer, agree with the book’s authors? Explain your answer.
Yes. In the last statement he says, “Let’s be green consumers and enjoy a better life on Earth”. The reviewer agrees that it is important to be a green consumer.
6. Do you agree with the reviewer’s opinion in the last sentence? Why or why not?
7. Based on the article, what habits do you have that you could change to be a greener consumer?
(While-reading) Green Consumer TipsFocus on ‘Paragraph form & Organization’We humans have done a lot of damage to the Earth!
Burning fuels. By burning fuels, we produce a lot of CO2 which is the main greenhouse gas.
With more CO2 in the atmosphere, the Earth keeps getting ... The Earth therefore is getting so warm that …Then the sea will rise and cause floods.
Using CFCs in daily life. …
Cutting down trees. …
Throwing away too much rubbish. …
I’m now considering being a careful green consumer.
Although my family prefer travelling by car, I will suggest driving less so that …. I hate / don’t like wearing masks all the time.

The pollution from burning fuels causes the greenhouse effect.
CO2 in the atmosphere stops heat from leaving the Earth. When people burn fuels, they produce a lot of CO2. This makes the Earth keep in much heat from the Sun.
2. Burning or cutting down trees makes the greenhouse effect worse.
Trees take in CO2 which leads to the greenhouse effect. Burning or cutting down trees, of course, lowers their chances of taking in CO2. What’s worse, trees themselves release CO2 in burning.
3. Global warming happens because of the greenhouse effect.
4. With too much CO2 in the atmosphere, our world may be flooded one day.
5. The atmosphere around the Earth acts like the glass of a greenhouse.
6. If we use fewer CFCs, the ozone layer will be protected.
7. More CO2 in the atmosphere will cause the sea level to rise.

6 The book is asking ______.
a young people to do something to help protect the environment
b more young people to become consumersWhile you readThis book says our world is in danger. It describes the various threats to the environment. The situation is so serious that we must do something to save the Earth.The green consumerThe greenhouse effect
The writers ask us to ‘imagine that the Earth is inside a kind of greenhouse with the atmosphere around it. The atmosphere acts like the glass: it lets sunlight in and keeps warmth from getting out. The atmosphere is essential for all living things. Without it, the Earth would be as cold and lifeless as the surface of the moon’.
‘The trouble is that our atmosphere is changing because we are polluting it with chemicals—in the form of gases—and it is keeping in too much heat!’
These gases, mainly carbon dioxide (CO2), are produced by burning fuels such as petrol. The greenhouse effect may cause the level of the sea to rise and flood cities and even whole countries.Damage to the ozone layer
The writers tell us that ‘ozone is a gas which occurs 20 to 50 km above the ground. It forms an essential protective layer around the Earth. Without it, the Sun would burn us up.
We are making holes in the ozone layer, mainly by using chemicals called CFCs. We use these in fridges and spray cans, and to make plastic items such as fast food boxes.Destruction of the forests
The burning and cutting down of the forests is making the greenhouse effect worse because trees take in CO2. It also causes soil erosion and flooding, as well as destroying the homes of people and animals that live in the forests.Bad habits
Many of our habits cause pollution, especially our habit of using things once and then throwing them away. This creates massive mountains of rubbish. We do not know what to do with the rubbish and it pollutes our land and sea. For example, people throw away as many as seven billion drink cans in Britain each year. That is enough to reach from the Earth to the moon.How can we save the Earth?
The book is asking us to become ‘green consumers’. That means we should only buy and use environmentally friendly goods so that we can save the Earth. These goods will not damage the environment.
Let’s be green consumers and enjoy living a better life on the Earth!ConsolidationWorkbook 9B, pages 1, 9 and 10.

The atmosphere is essential for all living things. Without it, the Earth would be as cold and lifeless as the surface of the moon’.

These gases, mainly carbon dioxide (CO2), are produced by burning fuels such as petrol. The greenhouse effect may cause the level of the sea to rise and flood cities and even whole countries.Damage to the ozone layer
The writers tell us that ‘ozone is a gas which occurs 20 to 50 km above the ground. It forms an essential protective layer around the Earth. Without it, the Sun would burn us up.
We are making holes in the ozone layer, mainly by using chemicals called CFCs. We use these in fridges and spray cans, and to make plastic items such as fast food boxes.Destruction of the forests
The burning and cutting down of the forests is making the greenhouse effect worse because trees take in CO2. It also causes soil erosion and flooding, as well as destroying the homes of people and animals that live in the forests.Bad habits
Many of our habits cause pollution, especially our habit of using things once and then throwing them away. This creates massive mountains of rubbish. We do not know what to do with the rubbish and it pollutes our land and sea. For example, people throw away as many as seven billion drink cans in Britain each year. That is enough to reach from the Earth to the moon.How can we save the Earth?
The book is asking us to become ‘green consumers’. That means we should only buy and use environmentally friendly goods so that we can save the Earth. These goods will not damage the environment.
Let’s be green consumers and enjoy living a better life on the Earth!ConsolidationWorkbook 9B, pages 1, 9 and 10.
