Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s
fossil fuels are running out. What would happen if there were no oil, coal and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy
from the sun, the wind and the water.
Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for
rain, and to maintain the temperature of the planet. All are necessary for human life. If we’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.
11. We are asking the question “What would happen if there were no oil, coal and gas on earth?” because ___.
A. we are now depending so much on fossil fuels.
B. we are looking forward to seeing great changes.
C. we are looking for other alternative sources of energy.
D. other sources of energy can come from the sun, the wind and the water.
12. Which of the following can NOT be used as alternative sources of energy?
A. coal/gas B. the sun/the water
C. the sun/the wind D. solar energy/nuclear power
13. Centuries ago, people used wind power to ___.
A. maintain the earth’s temperature B. get water from underground
C. grow plants D. generate electricity
14. Up till now, water energy has been used for ___.
A. similar purposes C. the textile industry
B. moving ships D. different purposes

4
15. The word “plentiful” in line 8 mostly means ___.
A. fresh B. natural C. available D. limited

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. 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, nonrenewable 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 nonrenewable 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 nonrenewable fuels has created a dependency on a finite resource that will have to be replaced

According to the passage, the sources of fossil fuels will have to be replaced because

A. they need to be transported

B. they are not efficient

C. their use is centralized

D. their supply is limited

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. 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, nonrenewable 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 nonrenewable 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 nonrenewable fuels has created a dependency on a finite resource that will have to be replaced
