Câu 15 có sai gì không bạn

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