There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
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 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 with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped (压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
1、How many ways of dealing with the energy problem are discussed in the text? ()
A、Two.
B、Three.
C、Four.
D、Five.
2、From the text we learn that coal().
A、is quite easy to produce
B、is not used most efficiently
C、is the most common source of energy
D、could be renewed only by new technology
3、The writer tells about the "special houses" because they().
A、show the excellent skills of the builders
B、serve as an example of energy conservation
C、are heated by different sources of energy
D、are warmer than other types of houses
4、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
5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ? ()
A、One km.
B、 Two km.
C、 Three km.
D、 Four km

听力原文: An explosion in a Pennsylvania coal mine killed one worker Monday, but five other miners escaped. The blast went off 2,300 feet underground at the R&D coal mine in Schuylkill County. Some officials say it appears a blast went off in the anthracite mine when workers detonated the explosives, but that’s still under investigation.
The process right now is to continue the interviews and then get back down underground and complete the inspections and in that way we can complete the investigation as to what happened.
The brother-in-law of the miner killed says 43-year-old Dlae Reightler worked at the mine since he was a teenager and that he dreamed of moving his wife and four children, setting up an auto-repair business.
He did it all his life. He did that and worked on cars in his garage backyard. He enjoyed doing that stuff.
At the mine, the accident knocked out the ventilation system, making it too dangerous for investigators to go down into the mine shaft. Regulators ordered the facility closed until the investigation is complete. The area has the nation’s only deposits of anthracite, a type of hard, clean burning coal. A June inspection of the site turned up no violations and violations detected in August were fixed on site.
The investigation was dangerous because ______.
A.the mine was badly damaged
B.the ventilation system was broken
C.the mine was too deep
D.the safety facility was destroyed
