  There are different ways in which people try to deal with(处理) the problem of energy.One way is the greater production of common energy sources (能源), such as coal, oil and gas.The trouble with these sources, however, is that they are not renewable(可再生的).

  Another way is energy conservation(节能), which means using energy more efficiently(有效地).In some very cold countries people build special houses to save energy.They place materials(材料)between the inside and the outside of the walls of the house to keep the cold out and the warmth in.The house is heated by the lights, the body heat of the people and the other equipment in it.

  Finally,renewable energy sources are used even though they are often expensive to develop.One form of these is geothermal energy.In certain parts of the world the temperature of the earth increases thirty degrees centigrade(摄氏) with each kilometer down.As a result, at six kilometers, it rises to nearly two hundred degrees.To get the heat, water is pumped (压) down into the rocks and back up to the surface(表面).Heat from the earth is already used in certain countries.

1.From the text we learn that coal________.

A.is quite easy to produce

B.is not used most

C.is the most common source of energy

D.could be renewed only by new technology(技术)

2.The underlined words “geothermal energy”in the third paragraph mean “________”

A.renewable source

B.underground source

C.heat inside the earth

D.temperature of the earth

3.Which of the following drawings shows the right way to get geothermal energy?

4.At a place where the surface temperature is 15℃, how deep do you have to dig so as to get a temperature of 75℃?

A.One km.

B.Two km.

C.Three km.

D.Four km.

Disposing (处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

During the eighteenth century, it was usual for several neighboring towns to get together to select faraway spot as a dump site. Residents or trash haulers (垃圾拖运者) would transport house hold rubbish, rotted wood, and old possessions to the site. Periodically (定期的) some of the trash was buried and the rest was buried .Me unpleasant sights and smells caused no problem because nobody lived close by.

Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential (住宅区的) neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

Awareness (意识) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

The most suitable title for this passage would be

A.Places for Disposing Waste      B.Waste Pollution Dangers

C.Ways of Getting Rid of Waste     D.Waste Disposal Problem

During the 18th century, people disposed their waste in many ways EXCEPT for__________.

A.burying it              B.recycling it.

C.burning it              D.throwing it into rivers

What can be inferred from the fourth paragraph?

A.Farm areas accept waste from the city in modern society.

B.There is cheap land to bury waste in modern society.

C.It is difficult to find space to bury waste in modem society.

D.Ways to deal with waste in modem society stay the same.

The main purpose of writing this article is to________.

A.draw people's attention to waste management

B.warn people of the pollution dangers we are facing

C.call on people to take part in recycling programs

D.tell people a better way to get rid of the waste
