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（可再生的）.
Another way is energy conservation（节能）,which means using energy more efficiently.In some very cold countries,people build special houses to save energy.They place materials between the inside and outside of the walls of the house to keep the cold out and the warmth in.
Finally,renewable energy sources are used even though they are often expensive to develop.One form of these is geothermal energy（地热）.In certain parts of the world,the temperature of the earth increases thirty degrees centigrade（摄氏）with each kilometer down.At six kilometers,therefore,it rises to nearly two hundred degrees.Heat from the earth is already used in some countries.
6.Four different ways of dealing with energy problems are talked about in the passage.
7.We can learn from the passage that coal is the most common source of energy.
8.Special houses are built because they can save energy.
9.According to the passage,geothermal energy is heat inside the earth.
10.At four km deep,the temperature of the earth rises to nearly 200°C.
One day a bookseller（书商）let a big box of books fall on his foot.“Go to see the doctor,”said his wife.“No,“he said.“I’ll wait until the doctor comes into the shop next time.Then I’ll ask him about my foot.If I go to see him,I’ll have to pay him.”
On the next day the doctor came into the shop for some books.When the bookseller was getting them ready,he told the doctor about his bad foot.The doctor looked at it.
“You must put that foot in hot water every night.Then you must put something on it,”said the doctor.
He took out a piece of paper and wrote on it.“Buy this and put it on the foot before you go to bed every night,”he said.
“Thank you,”said the bookseller.“And now,sir,here are your books.”
“How much?”said the doctor.
“Good,”said the doctor.“I shall not have to pay you anything.”
“Why?”asked the bookseller.
“I told you about your foot.I want two pounds for that.If people come to my house,I ask them to pay one pound for a small thing like that.But when I go to their houses,I want two pounds.And I came here,didn’t I?”
