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.

VI. Read the passage and choose the correct answers.

Fossil fuel such as coal, oil and gas has been the world’s main energy source for the past few centuries. Humans began using fossil fuel in the 18th century during the industrial revolution. Its popularity increased in the mid1900s and became our primary source of energy. Nowadays fossil fuel accounts for more than 80% of the world’s energy consumption. However, fossil fuel is running out not only because it’s a non-renewable source of energy but also because of human population growth. Scientists believe that at current rate we will only have enough fossil energy to use until 2088. Many developed countries in the meantime have been investing in scientific programs trying to find the best replacement for fossil fuel.

1)1. What does the writer call fossil fuel in the passage?

A. Primary source of energy and non-renewable source of energy.

B. Primary source of energy, non-renewable source of energy and fossil energy.

C. Fossil energy and non-renewable source of energy.

D. None are correct.

2)How much fossil fuel do people in the world consume today?

A. All of fossil fuel in the world.

B. 80% of fossil fuel in the world.

C. 4/5 of the world’s energy consumption.

D. ½ the world’s energy consumption.

3. Why does fossil fuel run out?

A. Because it cannot be renewed.

B. Because more and more people use it and it cannot be renewed.

C. Because more and more people use it.

D. Because some scientists said so

4)What are many developed countries doing to solve the problem?

A. They are searching for new source of energy.

B. They are predicting the amount of fossil fuels.

C. They are studying some ways to renew fossil fuels.

D. They are advising people not to use fossil fuels.

5)5. Which of the following is NOT discussed in the passage?

A. Fossil energy has been mainly used since 18th century.

B. Fossil energy became popular in the mid-1900s.

C. Fossil fuel is believed to run out by 2088.

D. Fossil fuel can be replaced by another non-renewable source of energy.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations (which were set up at the end Of the nineteenth century by Edison himself). As more power plants were constructed throughout the country, the reliance on coal increased. Since the First World War, coal-fired power plants have accounted for about half of the electricity produced in the United States each year. In 1986 such plants had a combined generating capacity of 289,000 megawatts and consumed 33 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas, coal-fired power plants could well provide up to 70 percent of the electric power in the United States by the end of the century.

Yet, in spite of the fact that coal has long been a source of electricity and may remain one for many years (coal represents about 80 percent of United States fossil-fuel reserves), it has actually never been the most desirable fossil fuel for power plants. Coal contains less energy per unit of weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. Since the late 1960's problems of emission control and waste disposal have sharply reduced the appeal of coal-fired power plants. The cost of ameliorating these environmental problems, along with the rising cost of building a facility as large and complex as a coal-fired power plant, has also made such plants less attractive from a purely economic perspective.

Changes in the technological base of coal fired power plants could restore their attractiveness, however. Whereas some of these changes are evolutionary and are intended mainly to increase the productivity of existing plants, completely new technologies for burning coal cleanly are also being developed

According to the passage, which of the following is one of the goals of the new technology in coal-fired plants?

A. To adapt the plants to other kinds of fuel

B. To reduce the cost of building more plants

C. To lengthen the lives of plants already in use

D. To make the plants already in use more productive

B. The cost of changing to other fuels is too great.

C. The future availability of other fuels is uncertain.

D. Other fuels present too many environmental problems.
