1 Warm-up:
Game: Pictionary
* Dividing the class into four groups
* Preparing some pieces of paper on
which there is one word : ocean / sun /
land / grass / air / coal / oil / …
* Give a piece of paper to one person in
each group This person doesn’t show
it to the others in his or her group , then
explain the word by drawing When
the others in his group can recognize
what the word is, they will say it aloud
The groups that has more right words
will win the game
* Checking the students’ understanding
of the instruction
* Declaring the winning group
Lead-in:
* Having the students show the pictures
they have just drawn and ask : what do
these pictures refer to ?
Expected answer:
They are about natural resources
* Emphasizing the students’ answers
and introducing the lesson
* Writing the title of the lesson on B/B

Trang 4 Tape script (cơ bản)
The natural environment includes all natural resources that are necessary for life: the air, the ocean , the sun and the land Because they are vital for life These resources must be protected from pollution and conserved Ecologists study their importance and how to use them carefully
According to ecologists, resources are divided into two groups: renewable and non-renewable When a resource is used, it takes some time to replace it If the resource can be replaced quickly, it is called renewable If it can’t be replaced quickly and easily, it is non-renewable For example, grass for animals is a renewable resource When cows eat the grass, the resource is used If the soil is fertilized and protected , more grass will grow Coal, however, is nonrenewable because it takes millions of years to make coal All fossil fuels are nonrenewable resources
Solar energy , air, and water are renewable resources because there is an unlimited supply However, this definition may change if people are not careful with these resources The amount of solar energy that reaches the earth depends on the atmosphere If the atmosphere is polluted, the solar energy that reaches the earth may be dangerous if life is going to continue, the air must contain the correct amount of nitrogen (N), oxygen (O) , carbon dioxide (CO2) , and other gases If humans continue to pollute the air , it will not contain the correct amounts of these gases

B) Mr John Jackson is giving a lecture on energy sources Listen to the first part and check the ideas that are not mentioned in his lecture.
Today I am very pleased to talk about a topic that is so essential to our environment – energy sources The demand for energy, as I’m sure you all know, is increasing more rapidly than ever The non-renewable sources such as coal and oil have been used for cooking , lightning , heating , and generating electricity for centuries … um … to serve our life However, they are harmful to the environment , as they produce a lot of smoke when we burn them And what’s more , they are running out That’s why people are looking for sources that are almost limitless and clean – I mean the renewable sources.
2 , 3 , 4 , 6 ,7
C) Look at the pictures Listen to the second part and complete the diagram.
As I have just said, the renewable sources are limitless Most of them do not cause pollution, or at least less pollution than coal or oil Let me give you an example of biomass Biogas is a kind of biomass produced from animal matter It is safe and clean enough Corn
is the biomass from plants It is ground and then made into sugars These sugars are then made into ethanol , a kind of fuel used for cars Cars using ethanol may give out carbon dioxide, which pollutes the air But when you grow another new crop of corn, the corn takes
up the carbon dioxide in the air to reduce air pollution As you can see now, this source of energy never runs out and it causes less pollution.
