The Chinese have used a method called acupuncture (针灸) to perform operations for about4,000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them. To learn how to use the needles takes about one month of training. But to be skillful requires greater time. The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.
Today, the Chinese doctors are trying to learn more about acupuncture. They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, would prevent the pain in the area of the mouth.
A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation but the chemical may make the patient sick for a few hours or a day.

How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs?
These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.
For a long time, people buried garbage or dumped (倾倒) it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil (化石）fuels. As we use up our fossil fuel supplies, we might be able to use garbage as an energy source.
Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants bum almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil. Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.
What two problems can man solve by burning garbage?
A．The shortage of energy and air pollution.
B．The shortage of energy and the land to hold garbage.
C．Air pollution and the shortage of fossil fuel.
D．Air pollution and the shortage of land to hold garbage.


17、 Which of the following is not the result of burning garbage?
A．The garbage burned is turned into fossil fuels.
B．The heat produced is used to boil water.
C．The steam produced is used to make electricity.
D．The steam produced is used to heat buildings.


18、 According to the passage which of the following is NOT true?
A．About 2 million rnetfic tons of garbage is burned in some power plants in Paris, France each year.
B．In a modem society, more and more garbage is produced each year.
C．Using garbage is a good way to solve the problem of energy shortage.
D．It will be too expensive to use garbage as an energy source.


19、 What is the author’s attitude?
A．Delighted.
B．Sad.
C．Agreeing.
D．Disagreeing.


20、 The best title for the passage may be__________.
A．Garbage and the Earth
