 a. Read the text and underline the correct title.

(Đọc văn bản và gạch chân chủ đề đúng.)

1. The Advantages of Clean Energy Sources (Lợi ích của năng lượng sạch)

2. Comparing Different Energy Sources (So sánh các nguồn năng lượng khác nhau)

Choosing the best option for energy can be difficult. Coal power is the most popular form of energy today because coal plants aren't expensive to build. However, they can produce a lot of pollution. Other non-renewable energy sources, like natural gas, are cleaner than coal, but they still aren't good for the environment.

Countries are now moving to renewable sources of energy like wind, solar, and hydroelectric power.

Wind and solar power plants are clean and cheap to run, but they aren't cheap to build. Also, wind turbines are noisy and need windy weather to work well, and solar power doesn't work at night. Hydroelectric plants also don't cause pollution, but they can be expensive to build and affect the environment by stopping fish from moving freely. For these reasons, countries and cities usually choose a mix of energy types.

Tạm dịch:

Lựa chọn tốt nhất cho năng lượng có thể khó khăn. Năng lượng từ than đá là dạng năng lượng phổ biến nhất hiện nay vì các nhà máy than không tốn kém để xây dựng. Các nguồn năng lượng không tái tạo khác như khí đốt tự nhiên, sạch hơn than đá, nhưng chúng vẫn không tốt cho môi trường. Các quốc gia hiện đang chuyển sang các nguồn năng lượng tái tạo như gió, mặt trời và thủy điện. Các nhà máy điện gió và năng lượng mặt trời sạch sẽ và rẻ để chạy, nhưng chúng không rẻ để xây dựng. Các nhà máy thủy điện cũng không gây ô nhiễm, nhưng chúng có thể tốn kém để xây dựng và ảnh hưởng đến môi trường bằng cách ngăn cá di chuyển tự do. Vì những lý do này, các quốc gia và thành phố thường chọn kết hợp các loại năng lượng.

Ex1. Use the correct form of words:

1. Nuclear energy can provide enough ..electrity.... for the word's need, but it is ..dangerous.. (electric/ danger)

2. Coal is ..limitative.. and it will be ..replaced.. by another .renewable.. sources. (limit/ replace/ renew)

3. Wind power is ..convenient.. and .abundant.. (conveniene/ abundance)

4. Renewable source won't cause .pollution.. or waste ..natural. resources. (pollute/ nature)

5. By using solar energy the prolem of the energy ..shortage. will be solved. (short)

2. Natural gas is cheap, but it is excellent for cooking.

(Khí ga tự nhiên rẻ, nhưng nó rất tuyệt khi nấu ăn.) 

3. The power plant is big and it provides enough power for the whole town.

(Nhà máy điện lớn và nó cung cấp đủ năng lượng cho cả thị trấn.)

4. The solar panels are expensive to buy, but they save money in electricity bills later.

(Các tấm pin mặt trời rất tốn kém để mua, nhưng chúng tiết kiệm tiền trong hóa đơn tiền điện sau này.)

5. My father loves a coal fire, but I hate it.

(Bố tôi thích lửa than nhưng tôi ghét nó.)

6. I don't think we should use nuclear power, but my brother thinks using it is a good idea.

(Tôi không nghĩ chúng ta nên sử dụng năng lượng hạt nhân, nhưng anh trai tôi nghĩ rằng sử dụng nó là một ý tưởng tốt.)

Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun

At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population

Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too

Questions

1. Is the solar energy an effective source os power?

=>Yes,it is

2.Where are the solar panels placed?

=>They are placed on the roof of a house.

3.Is the solar energy used in Vietnam now?

=>Yes,it is
