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 write the letter A, B, C or D on the top of the first page to indicate the correct answer to each of the questions.

In the course of its history, human inventions have dramatically increased the average amount of energy available for use per person. Primitive peoples in cold regions burned wood and animal dung to heat their caves, cook food, and drive off animals by fire. The first step toward the developing of more efficient fuels was taken when people discovered that they could use vegetable oils and animal fats in lieu of gathered or cut wood. Charcoal gave off more intensive heat than wood and was more easily obtainable than organic fats. The Greeks first began to use coal for metal smelting in the 4th century, but it did not come into extensive use until the Industrial Revolution.

In the 1700s, at the beginning of the Industrial Revolution, most energy used in the United States and other nations undergoing industrialization was obtained from perpetual and renewable sources, such as wood, water streams, domesticated animal labor, and wind. These were predominantly locally available supplies. By mid-1800s, 91 percent of all commercial energy consumed in the United States and European countries was obtained from wood. However, at he beginning of the 20th century, coal became a major energy source and replaced wood in industrializing countries. Although in most regions and climate zones wood was more readily accessible than coal, the latter represents a more concentrated source of energy. In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less. Unlike coal, oil could be refined to manufacture liquid fuels for vehicles, a very important consideration in the early 1900s, when the automobile arrived on the scene.

By 1984, non-renewable fossil fuels, such as oil, coal, and natural gas, provided over 82 percent of the commercial and industrial energy used in the world. Small amounts of energy were derived from nuclear fission, and the remaining 16 percent came from burning direct perpetual and renewable fuels, such as biomass. Between 1700 and 1986, a large number of countries shifted from the use of energy from local sources to a centralized generation of hydropower and solar energy converted to electricity. The energy derived from non-renewable fossil fuels has been increasingly produced in one location and transported to another, as is the case with most automobile fuels. In countries with private, rather than public transportation, the age of non-renewable fuels has created a dependency on a finite resource that will have to be replaced.

Alternative fuel sources are numerous, and shale oil and hydrocarbons are just two examples. The extraction of shale oil from large deposits in Asian and European regions has proven to be labor consuming and costly. The resulting product is sulfur-and nitrogen-rich, and large scale extractions are presently prohibitive. Similarly, the extraction of hydrocarbons from tar sands in Alberta and Utah is complex. Semi-solid hydrocarbons cannot be easily separated from the sandstone and limestone that carry them, and modern technology is not sufficiently versatile for a large-scale removal of the material. However, both sources of fuel may eventually be needed as petroleum prices continue to rise and limitations in fossil fuel availability make alternative deposits more attractive.
Question:According to the passage, what was the greatest advantage of oil as fuel?

A. it was a concentrated source of energy.

B. it was lighter and cheaper than coal.

C. it replaced wood and coal and reduced pollution.

D. it could be converted to automobile fuel.

B. Tài nguyên thiên nhiên và nhiên liệu hoá thạch

C. Lịch sử của việc sử dụng năng lượng

D. Một đánh giá mang tính lịch sử về mức năng lượng

Dịch bài đọc

Trong quá trình lịch sử, các phát minh của con người đã làm tăng đáng kể lượng năng lượng có sẵn mỗi người sử dụng. Người nguyên thủy ở vùng lạnh đốt gỗ và phân động vật để sưởi ấm các hang động của chúng, nấu thức ăn và thịt thú bằng lửa. Bước đầu tiên để phát triển các nhiên liệu hiệu quả hơn đã được thực hiện khi người ta phát hiện ra rằng họ có thể sử dụng dầu thực vật và chất béo động vật thay vì nhặt hoặc chặt gỗ. Than củi cho nhiệt độ cao hơn gỗ và dễ dàng hơn chất béo hữu cơ. Người Hy Lạp lần đầu tiên bắt đầu sử dụng than đá để luyện kim vào thế kỷ thứ 4, nhưng nó đã không được sử dụng rộng rãi cho tới Cách mạng Công nghiệp.

Vào những năm 1700, khi bắt đầu Cuộc Cách mạng Công nghiệp, hầu hết năng lượng được sử dụng ở Hoa Kỳ và các quốc gia khác trải qua quá trình công nghiệp hóa đều lấy từ các nguồn năng lượng lâu dài và có thể tái tạo như gỗ, suối nước, động vật đã thuần hóa và gió. Đây là nguồn cung cấp chủ yếu ở địa phương. Vào giữa những năm 1800, 91% lượng năng lượng thương mại tiêu thụ ở Hoa Kỳ và các nước Châu Âu được lấy từ gỗ. Tuy nhiên, vào đầu thế kỷ 20, than trở thành nguồn năng lượng chính và thay thế gỗ trong các nước công nghiệp hóa. Mặc dù ở hầu hết các vùng và khu vực khí hậu, gỗ có thể tiếp cận dễ dàng hơn than, loại nhiên liệu này đại diện cho một nguồn năng lượng tập trung hơn. Năm 1910, khí đốt tự nhiên và dầu thay thế than đá như là nguồn nhiên liệu chính vì chúng nhẹ hơn, và do đó rẻ hơn để vận chuyển. Chúng đốt sạch hơn than đá và ô nhiễm ít hơn. Không giống như than đá, dầu có thể tinh chế để sản xuất nhiên liệu lỏng cho xe cộ, một cân nhắc rất quan trọng vào đầu những năm 1900 khi ô tô xuất hiện.

Đến năm 1984, nhiên liệu hóa thạch không tái tạo được, như dầu, than và khí tự nhiên, cung cấp trên 82 phần trăm năng lượng thương mại và công nghiệp được sử dụng trên thế giới. Một lượng nhỏ năng lượng xuất phát từ sự phân hạch hạt nhân, và 16% còn lại là do đốt nhiên liệu vĩnh viễn và tái tạo trực tiếp như khí ga. Từ năm 1700 đến năm 1986, một số lượng lớn nước chuyển từ việc sử dụng năng lượng địa phương sang một thế hệ thủy điện và năng lượng mặt trời được chuyển đổi thành điện. Năng lượng có nguồn gốc từ nhiên liệu hóa thạch không tái tạo được ngày càng phổ biến, được sản xuất tại một địa điểm và được vận chuyển tới một nơi khác, như trường hợp của hầu hết các nhiên liệu ô tô. Ở các nước sử dụng phương tiện giao thông tư nhân thay vì phương tiện giao thông công cộng, tuổi của các nhiên liệu không tái tạo đã tạo ra sự phụ thuộc vào nguồn tài nguyên hữu hạn mà sẽ phải được thay thế.

Nguồn nhiên liệu thay thế là rất nhiều, và dầu đá phiến sét và hydrocarbon chỉ là hai ví dụ. Việc khai thác dầu đá phiến từ các mỏ lớn ở khu vực châu Á và châu Âu thì tiêu tốn nhiều lao động và tốn kém. Sản phẩm thu được giàu sulfur và giàu nitơ, và việc chiết suất quy mô lớn hiện đang bị cấm. Tương tự, việc khai thác các hydrocarbon từ cát nhựa ở Alberta và Utah lại phức tạp. Hydro cacbon rắn không thể dễ dàng tách ra khỏi đá sa thạch và đá vôi mà mang chúng, và công nghệ hiện đại không đủ linh hoạt cho việc loại bỏ tạp chất. Tuy nhiên, cả hai nguồn nhiên liệu có thể sẽ là cần thiết vì giá xăng dầu tiếp tục gia tăng và những hạn chế trong việc cung cấp nhiên liệu hoá thạch làm cho nguồn thay thế trở nên hấp dẫn hơn.

In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less. Unlike coal, oil could be refined to manufacture liquid fuels for vehicles, a very important consideration in the early 1900s, when the automobile arrived on the scene.

By 1984, non-renewable fossil fuels, such as oil, coal, and natural gas, provided over 82 percent of the commercial and industrial energy used in the world. Small amounts of energy were derived from nuclear fission, and the remaining 16 percent came from burning direct perpetual and renewable fuels, such as biomass. Between 1700 and 1986, a large number of countries shifted from the use of energy from local sources to a centralized generation of hydropower and solar energy converted to electricity. The energy derived from non-renewable fossil fuels has been increasingly produced in one location and transported to another, as is the case with most automobile fuels. In countries with private, rather than public transportation, the age of non-renewable fuels has created a dependency on a finite resource that will have to be replaced.

Alternative fuel sources are numerous, and shale oil and hydrocarbons are just two examples. The extraction of shale oil from large deposits in Asian and European regions has proven to be labor consuming and costly. The resulting product is sulfur-and nitrogen-rich, and large scale extractions are presently prohibitive. Similarly, the extraction of hydrocarbons from tar sands in Alberta and Utah is complex. Semi-solid hydrocarbons cannot be easily separated from the sandstone and limestone that carry them, and modern technology is not sufficiently versatile for a large-scale removal of the material. However, both sources of fuel may eventually be needed as petroleum prices continue to rise and limitations in fossil fuel availability make alternative deposits more attractive.

The author of the passage implies that alternative sources of fuel are curently

A. being used for consumption

B. available in few locations

C. being explored

D. examined on a large scale

Read the following passage and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each for the questions.

In the course of history, human inventions have dramatically increased the average amount of energy available for use per person. Primitive people in cold regions burned wood and animal dung to heat their caves, cook food, and drive off animals by fire. The first step toward the developing of more efficient fuels was taken when people discovered that they could use vegetable oils and animal fats in lieu of gathered or cut wood. Charcoal gave off a more intensive heat than wood and was more easily obtainable than organic fats. The Greeks first began to use coal for metal smelting in the 4^th century, but it did not come into extensive use until the Industrial Revolution.

In the 1700s, at the beginning of the Industrial Revolution, most energy used in the United States and other nations undergoing industrialization was obtained from perpetual and renewable sources, such as wood, water streams, domesticated animal labor, and wind. These were predominantly locally available supplies. By mid-1800s, 91 percent of all commercial energy consumed in the United States and European countries was obtained from wood. However, at the beginning of the 20^th century, coal became a major energy source and replaced wood in industrializing countries. Although in most regions and climate zones wood was more readily accessible than coal, the latter represents a more concentrated source of energy. In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less.
