Giải bài 16 từ câu số 15 đến 45 giùm mik nha mọi ng

Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative. However, many people don't approve of using nuclear power because it is very dangerous. What would happen if there were a serious nuclear accident ? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economically as possible.

1. According to the passage, using nuclear power is ________

A. dangerous B. interesting C. safe D. cheap

2. Radioactivity from nuclear power ________

A. the future generations do nothing with it

B. alters a new kind of energy

C. are necessary to cure diseases

D. causes cancer and has bad effect on the future generations

3. How much fuel is left ?

A. No one know exactly

B. Let's use it as much as we would like

C. It will never be used up

D. There is a lot of fuel

4. We should use coal, oil and gas ________

A. as economically as possible B. carelessly C. as much as possible D. all are incorrect

5. According to Professor Marvin Burnham, ________

A. Nuclear power is the only alternative coal, oil and gas and we have to conserve are incorrect

B. Nuclear power is the only alternative coal, oil and gas

IV. Read the passage, and choose the correct answer A, B, C or D for each question

. 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 will happen when there is no oil, coal and gas on the 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. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperate of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source od power.

1. From which do plants on the earth get energy?

A. stars B. the Mars C. the moon D. the sun

2. What are the other words or phrase for fossil fuels?

A. natural gas B. oil C. coal D. oil, gas, natural gas

3. Natural sources of energy are energy from .

A. wind B. the sun C. water D. the sun, wind, water

4. The word “abundant” in the passage is closet in meaning with .

A. plentiful B. limited C. natural D. necessary

5. We are asking the question, “What will happen when there is no oil, coal, and gas on the earth?” because . A. we are now depending so much on oil, coal, and natural gas

B. other sources of energy can come from the sun, wind, and water

C. we are looking forward to seeing great changes

D. we are looking for other alternative sources of energy

SOLAR ENERGY

Sunlight carries huge amounts of energy. You can feel the Sun’s energy when sunlight warms your skin on a summer day. To capture the Sun’s energy, scientists have developed solar cells, called photovoltaic cells. These cells convert sunlight into electricity.

When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the particles in the solar cell to move faster, and the movement of these particles creates electricity.

In some places, large panels of solar cells harvest sunshine to make electricity for homes and businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their energy costs.

Experts say that the huge installation of solar panels in sunny regions could generate enough electricity to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. New ways to capture this energy are being developed all the time to maximize efficiency.

1. What is the source of solar energy?

  a. sunlight                            b. photovoltaic cells c. solar panels                       d. electricity

 2.  Solar cells are used

a. to collect energy from the sun b. to provide sunlight to houses

c. to convert sunlight into electricity              d. both a and c are correct 

3. Which of the following statements is true?

a. Solar cells absorb all of the light energy from the sun.

b. The light energy causes the particles to move faster to make electricity.

c. Solar energy can be used to power homes and businesses only.

d. Large solar panels have been placed on cars and appliances.

4. As used in line 9, ‘abundant’ most nearly means .

     a. unlimited                b. dangerous              c. plentiful              d. clean

5. Where have people fixed solar panels?

a. In the sunniest places b. Anywhere outside their houses

c. Inside their houses d. On the roofs of their houses

6. As used in line 14, ‘diminishing’ most nearly means .

    a. decreasing b. increasing c. unending d. restoring

7. According to the passage, all of the following statements are true EXCEPT

a. the Sun produces a large amount of energy.

b. solar energy could provide enough electricity for the whole world

c. scientists are constantly developing new ways to capture the Sun’s energy

d. people use solar energy to reduce their energy costs.
