Trang 1UNIT 11: SOURCES OF ENERGY
Listening text 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 nonrenewable When a resource is used, it takes some time to replace it If the resource can be replaced quickly, it
is called 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 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
Task 1: List and learn by heart important words or phrases.
Task 2: Translate the passage into Vietnamese.

Bỏ who, which, that và be (nếu có ), thêm ING vào động từ

MĐQH xác định, đóng vai trò làm từ bổ nghĩa, làm rõ nghĩa cho danh từ đứng trước nó

Trong phần to inf này chúng ta cần nhớ 2 điều sau:
- Nếu chủ từ 2 mệnh đề khác nhau thì thêm cụm for sb trước to inf
We have some picture books that children can read
We have some picture books for children to read
Tuy nhiên nếu chủ từ đó là đại từ có nghĩa chung chung như we,you,everyone thì có thể không cần ghi ra
Studying abroad is the wonderful thing that we must think about
Studying abroad is the wonderful thing (for us ) to think about
- Nếu trước ĐTQH có giới từ thì phải đưa xuống cuối câu ( đây là lỗi dễ sai nhất)
We have a peg on which we can hang our coat
We have a peg to hang our coat on
3 Dùng cụm danh từ (đồng cách danh từ )
Dùng khi mệnh đề tình từ có dạng:
S + BE + DANH TỪ /CỤM DANH TỪ/CỤM GIỚI TỪ
Cách làm: -bỏ who, which và be
