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 men might be able to solve both problems at the same time. They suggest using garbage as an energy source.

For a long time people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. But 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 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 US 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 burn almost 2 million metric tons of the city’s 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.

But there are problems in using garbage as a fuel. Garbage that burns easily, such as food scrapes and paper, must be separated from metals, glass, and other materials that do not burn easily. This separation process is normally costly. Another problem is that burning garbage can pollute the air.

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.

1. What two problems can be solved by burning garbage?

A. The shortage of energy; Air pollution.

B. The shortage of energy; The shortage of empty land for holding garbage.

C. Air pollution; The shortage of empty land for holding garbage.

D. Air pollution; The garbage of fossil fuel.

2. Which of the following is NOT a result of burning garbage?

A. The heat produced is used to boil water.

B. The steam produced is used to make electricity.

C. The garbage burned is turned into fossil fuels.

D. The steam produced is used to heat buildings.

3. According to the passage, which of the following four groups of garbage is ready for burning?

A. Food scraps and metals.                B. Paper and glass.

C. Metals and glass.                      D. Food scraps and paper.

4. Which of the following methods of exposition is not used in the passage?

A. Questions and answers.             B. Figures.

C. Examples.                      D. Analogy.

  Milk was one of the main foods of people long before history was written.It will probably keep on being one as long as there are animals that give milk.

  Even the word “milk”is very old.It comes from Sanskrit(梵文),one of the oldest languages known to man.A very old picture of milking has been found.It was drawn more than five thousand years ago.

  In the years long ago, people got their milk from their own animals.But later new inventions made the milk industry a big business.In 1851 Gail Borden found a way to take some of the water out of milk.This made it keep much longer.Four years later, Louis Pasteur introduced a way to kill the bacteria(细菌)in milk.Next, a special milk bottle was made.This was followed by the invention of machines that could fill bottles with milk.

  These discoveries had a great effect on the milk industry.They meant that milk could be stored longer.

  Some people believe that milk drinking will become less popular than it has been.But remember how long milk has been an important food and think of many ways in which it is useful.It seems safe to say that milk industry will always be important.
