Rivers are on of the world's most important natural resources. Many cities are on the large rivers, and almost every country has a least one river that plays an important part in the lives of its people. Besides transportation, rivers provide water for crops, water to drink, and recreation for people who live along their banks And in order to get water for crops, engineers sometimes build a dam across a river and let water become a lake behind the dam. Then people can use their water not only to irrigate fields but also to make electricity for homes and industries. However the water often becomes polluted when cities on river bank grow in size and the number of industries increases. We are learning that it is necessary to keep rivers clean if we want to enjoy the benefits of the natural resources.

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

Đáp án: A

B. topsoil

Agricultural irrigation systems use topsoil as the source of water, providing essential nutrients and moisture to plants.

A water source may include rivers, underground aquifers, or man-made reservoirs, which are crucial for agricultural irrigation and maintaining healthy ecosystems.

The problem of soil erosion and its effects on water sources can arise when land-use practices do not consider the impact of such practices on soil health and water availability. This can be addressed through soil conservation measures and sustainable land-use planning.

Forest management can also play a role in addressing water conservation challenges, as well as providing valuable ecosystem services such as carbon sequestration and biodiversity preservation. The reforestation of degraded landscapes, as well as the promotion of sustainable forest management practices, can help mitigate the effects of water scarcity and promote water security for future generations.</s
