阅读下列短文,从每题所给的(A、B、C和D)四个选项中,选出最佳选项。

  There are new findings that not enough sleep may causepeople to gain weight.Researchers say a lack of sleep can produce hormonal(激素的)changes that increase feelings of hunger.

  In one study,researchers in the Unied States examinedinformation on more than 1000 people.The people had taken part in a long term study of sleep disorders.

  Some people slept less than five hours a night.They had15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less oFthe hormone leptin.Experts say ghrelin helps make peoplefeel hungry;leptin makes yon feel full.

  The scientists say these hormona changes may be a cause of obesity(肥胖症)in Western societies.They note the combination that ________ limitation is common ________ and is widely available(可得到的).

  The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researehers say loss of sleep may increase hunger especially for high-caloie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep.

  Researchers from Stanford University in California andthe University of Wisconsin did the study.They found thatthe best amount of sleep for weight control is 7.7 hours anight.

  The Public Library of Science published the findings inits journal Medicine.Internet users can read the full study,free of charge,at plos.org.

  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.
