[填空题]
It was the ambition of an eleven-year old boy in Kansas City to be an engine-driver. Born without arms, he had been to special schools where he learned to use his feet as "hands". He spent all his spare time watching trains and one day his dreams came true. Seeing a deserted engine, the boy climbed in. He had no difficulty in starting it up with his feet. Soon he was traveling along at forty miles an hour. Signalmen could not see the young driver. So they set out to stop the train. Meanwhile the boy reached Missouri, stopped the engine himself, and then made it go backwards. When he was near home, a railway-man caught up with the engine and stopped it. At first he was very angry, but he smiled when the boy said simply, "I like trains. "
"Well, I’ m glad you don’ t like planes !" answered the railway-man.
Why did the railway man smile （）

Where Have All the Frogs Gone?
In the 1980s,scientists around the world began to notice something strange:Frogs
were disappearing. More recent research has shown that many kinds of amphibians（两栖
动物）are declining or have become extinct. They have been around for a long time一over
350 million years.Why are they dying out now?
Scientists are seriously concerned about this question.First of all,amphibians are an
important source of scientific and medical knowledge.By studying amphibians,scientists
have learned about new substances that could be very useful for treating human diseases.
Further research could lead to many more discoveries,but that will be impossible if the
amphibians disappear.
The most serious aspect of amphibian loss,however,goes beyond the amphibians
themselves.Scientists are beginning to think about what amphibian decline means for the
planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming
unlivable for other kinds of animals and human beings as well?
Scientists now believe that amphibian decline is due to several environmental factors.
One of these factors is the destruction of habitat,the natural area where an animal lives.
Amphibians are very sensitive to changes in their habitat.If they cannot find the right
conditions,they will not lay their eggs一These days,as wild areas are covered with
houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs.
For example,the arroyo toad（蟾蜍）of southern California will only lay its eggs on the
sandy bottom of a slow-moving stream.There are very few streams left in southern
California,and those streams are often muddy because of building projects. Not
surprisingily,the arrovo toad is now in danaer of extinction.
There are a number of other factors in amphibian decline.Pollution is one of them.In
many industrial areas,air pollution has poisoned the rain,which then falls on ponds and
kills the frogs and toads that live there,In farming areas,the heavy use of chemicals on
crops has also killed off arrtphibians.Another factor is that air pollution has led to increased
levels of ultraviolet (UV) light. This endangers amphibians, which seem to be especially
sensitive to UV light. And finally, scientists have discovered a new disease that seems to
be killing many species of arnpttibians in different parts of the world.
All these reasons for the disappearance of amphibians are also good reasons for more
general concern. The destrriction of land, the pollcition of the air and the water, the
changes in our atmosphere, the spread of diseases-these factors affect human beings,
too. Amphibians are especially sensitive to environmental change. Perhaps they are like
the canary （金丝雀）bird that coal miners once used to take down into the mines to detect
poisonous gases. When the canary became ill or died,the miners knew that dangerous
gases were near and their own lives were in danger.
Coal miners once used the canary bird to detect
A.poisonous gases.
B.air pollution.

Once again the skeptics are murmuring that the successful Ricci has headed for a big fall. And once again Ricci intends to prove them wrong.
Ricci is so confident that he has christened. his quest "Operation Columbus" and has set his sights on discovering an American readership of 300,000.’That goal may not be too far-fetched.
