In Western countries, electricity, gas, and water are not luxuries but necessities. Companies now realize that consumers want products that will not only work effectively, but also save money.

For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eieht times longer. Therefore consumers can save about US$7 to US$21 per bulb.

In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared with other appliances in the same category.

Ultimately, these innovations will save money as well as conserve the Earth's resources.

Answer the questions: Mrs. Jones uses only two ordinary bulbs and she pays US$8 for lighting. How much will she pay if she uses two energy-saving bulbs instead? (Giải thích rõ lí do nhá mn)

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.

Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.

In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.

As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

What does the passage mainly discuss?

A. Humans and endangered species

B. The importance of living organisms

C. Measures to protect endangered species

D. Causes of animal extinction

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

Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.
