非谓语动词的恰当形式填空:
Don’t drink the ________(pollute)water.
Global warming is when the earth heats up,the temperature rises.It happens when greenhouse gases—carbon dioxide,water vapor,nitrous oxide(二氧化氮),and methane(沼气) trap heat and light from the sun in the earth’s atmosphere,which increases the temperature.This is like when heat is trapped in a car.On a very hot day,the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car,by going through the windows,but it can’t get back out.Once the light is inside the car,it is trapped and the heat builds up,just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere,but it can’t get out.As a result,the temperature rises.
Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it,the earth would be freezing,or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day,especially during the summer,it would be burning because the sun would be up with no atmosphere to filter(过滤) it,so people,plants,and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it,if there gets to be too many gases,the earth can get unusually warmer,and many plants,animals,and people will die.They would die because there would be less food (plants like corn,wheat,and other vegetables and fruits).This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat,but it would also limit the food that animals have.Gradually,people,plants,and animals would all die of hunger.
People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.
Another thing that people are doing is being more careful about leaving things turned on like the television,computer,and the lights.A lot of people are taking time away from the television,and instead,they are spending more time outdoors.This helps our planet out a lot.Now,more people are even riding buses,walking to school,and riding their bikes to lower the amount of greenhouse gases in the air.
Planting trees and recycling also help.If you recycle,less trash goes to the dump,and less trash gets burned.As a result,there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming,kids can do just as much.
1.By the example given in Paragraph 1,the author wants to ________.
A.explain how greenhouse gases work
B.show his feeling in a car in hot summer
C.tell us cars are causes of greenhouse gases
D.say that there are greenhouse gases in every car
2.The underlined word “it” in Paragraph 2 refers to “________”.
A.light? B.heat
C.temperature? D.greenhouse effect
3.What is the main idea of Paragraph 3?
A.If there is greenhouse effect,all the plants will die.
B.Human beings are likely to disappear from the earth.
C.Crops can’t take the heat if there is greenhouse effect.
D.Although greenhouse effect is necessary,too much of it causes us to die.
4.What will the author most probably discuss in the paragraph that follows?
A.Why cars and buses pollute the air a lot.
B.What kids can do to help stop global warming.
C.What global warming is doing to the environment.
D.Who should be responsible for the environmental problems.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. 1
Most Americans would find it hard to imagine what life would look like without cars. 2 . The polluted air becomes poisonous and dangerous to health.
3 . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of the car engine by something else. 4 . Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. 5 .
Although cars have led us to a better life, they have also brought us new problems.
A.Thus the problem of air pollution would become less important than that of unemployment. |
B.Americans know cars very well. |
C.However, some have realized the serious problems of the air pollution that is caused by cars. |
D.One way to get rid of the polluted air is to build a car that does not pollute. |
Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor. The type of home you have is another. Things like insulation(绝缘) present energy costs and the type of system you buy are added factors.
Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that’s all, the only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun.
We won’t have to worry about the sun’s running out of energy for another several billion years or so. Besides begin an endless source of energy, the use of the sun has other advantages as well. The sun doesn’t offer as many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With sola energy, we will still need sources of energy, but we won’t need as much. That means we can cut down on our pollution problems.
With all these good points, why don’t we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All this is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed. Solar energy is now in its infancy. It could soon grow to become a major part of our nation’s energy supply.
57. Which statement best expresses the main idea?
A. Something about Solar Energy and Pollution. B. Solar Energy.
C. Energy and Pollution D. Energy and Money
58. Solar energy can help us save ____.
A. the earth and nature resources B. mother nature
C. the sun D. our precious fuel
59. Which of the following statements is correct?
A. Energy from coal would not pollute our living environment.
B. Energy from natural gas would not pollute our living environment.
C. Energy from the sun would not pollute our living environment.
D. Energy from oil would not pollute our living environment.
60. Solar energy is in its infancy, ____.
A. but it will be considered as an important part of our nation’s energy supply
B. yet we will build more power plants
C. and the supply of electricity will be rationed
D. but we don’t need practice energy rationing now
