Fossi( Nhiên liệu hóa thạc)
Lý thuyết cho rằng nhiên liệu hóa thạch hình thành từ tàn tích hóa thạch của thực vật đã chết do tiếp xúc với nhiệt độ và áp suất trong lớp vỏ Trái đất trong hàng triệu năm được Andreas Libavius đưa ra lần đầu tiên "trong tác phẩm Alchemia [Alchymia] năm 1597" của ông và sau đó là bởi Mikhail Lomonosov "sớm nhất 1757 và chắc chắn là 1763". Thuật ngữ "nhiên liệu hóa thạch" lần đầu tiên được sử dụng trong công trình của nhà hóa học người Đức Caspar Neumann , trong bản dịch tiếng Anh năm 1759.
Coal ( than )
Than là một dạng nhiên liệu hóa thạch, được hình thành từ thực vật bị chôn vùi trải qua các giai đoạn từ than bùn, và dần chuyển hóa thành than nâu hay còn gọi là than non (lignit), và thành than bán bitum, sau đó thành than bitum hoàn chỉnh (bituminous coal), và cuối cùng là biến đổi thành than đá (anthracit). Quá trình biến đổi này là quá trình phức tạp của cả sự biến đổi về sinh học và cả quá trình biến đổi của địa chất. Đặc biệt, quá trình biến đổi về địa chất là cả một quãng thời gian được tính bằng hàng triệu năm.

XX. Read the text then circle the best answer.
Many people still believe that natural resources will never be used up.Actually,the worlds energy resources are limited.Nobody knows exactly how much fuel is left. However, we should use them economically and try to find alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative.
However, many people don't approve of using nuclear power because it is very dangerous. What would happen if there were a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economically as possible.
1. According to the passage, using nuclear power is...............
A. dangerous B. interesting C. safe D. cheap
2. Radioactivity from nuclear power.................
A. is harmless
B. alters a new kind of energy
C. is necessary to cure diseases
D. causes cances and may badly affect the future generations
3. How much fuel is left?
A. No one knows exactly B. Let' s use it as much as we would like
C. There is a lot of fuel D. It will never be used up
4. We should use coal, oil and gas...............
A. carelessly B. as economically as possible
C. as much as possible D. all are incorrect
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)
Put the word in the box in correct and fill in the sentences.
| renew - limit - danger - alternation |
1. .....renew ..... Powers include coal, petrol, natural gas and so on.
2. The amount of fossil fuels in the Earth is ....limit ....... so we should find .......alternation..... sources.
3. Nuclear energy is thought to be danger so if we use it, we will have to be very carefully.
| society - electricity - power - invest |
4. Driverless car may be solar-.....power...... so it will be very friendly with environment.
5. .......society...... problems and issues include hunger, poverty, bullying and so on.
6. I think ..electricity..... cars will be very popular because they will not harm to the environment. However, we will need to ...invest..... money in building charging station instead of petrol ones.
