　　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 fossilfuel 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 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.

At the time my son was born in 1956, I shared a hospital room with a young woman who bore a boy on the same day. Partly because my parents  46 a shop selling flowers, the room was soon  47  with the lovely scent of roses.
　  As the seventh floral arrangement was   48  , I was beginning to feel  49 , for no flowers had arrived for my roommate, Ann. She sat on the edge of her bed and leaned forward to admire the  50  bouquet. She was a pretty young woman, yet there was something about her large, brown eyes that made me think she had known too much  51 , too much sadness for one so young. I had the feeling she had always had to admire someone else’  52  .
　 “I’m enjoying every  53 of this”, she said as though she had read my   54  and was trying to reassure me. “Wasn’t I the lucky one to get you for a   55 ？”
　  I still felt uncomfortable, however.  56   there were some magic button I could push to  57   the sadness in her eyes. Well, I thought, at least,I can see that she has some flowers. When my mother and father came to see me that day, I asked them to send  58 some.
　　The flowers arrived just   59  Ann and I were finishing supper.
　　“More flowers for you,” she said,   60  .
　　“No, not this time,” I said, looking at the     61   “These are for you.”
　　Ann stared at the blossoms a long time, not saying anything. She ran her 62  across the pale blue bouquets and  63 touched each of the sweet roses as though trying to engrave（刻画） them on her 64 .
　　“How can I ever thank you” she said softly.
I was almost embarrassed. It was such a little    65  on my part.
