An Unusual Airplane Powered by Microwaves (微波动力飞机)
Canadian scientists have successfully tested an unusual airplane. The airplane is not powered by fuels. It is powered by microwaves. Microwaves can be produced by equipment on earth. When the microwaves hit the bottom of the plane's wings, instruments change them into a more usable form of energy - electricity powers the plane's engine.
The plane was developed by the Canadian government and the University of Toronto. The plane is called the sharpfire. The sharpfire is much too small to carry people or equipment. It was built only to see if the technology would work. Sharpfire is made of light weight wood. Its wings are about three and one half meters across. In its first public. A future microwave plane will be much larger than the sharpfire. The main reason for using microwave energy to power an airplane is to end the plane's need to carry fuel. An american researcher says this technology will be very common in the next century.

In the 1940s, Pinehaven Park was one of Crafton City's loveliest recreation(娱乐)areas. Over 40 acres of woods and fields were open to the public. In the 1950s, part of the park was taken over by Crafton City's garbage. Fifteen acres were to be used for landfill disposal(理置). As time went on, more and more of the park was used for garage disposal and less for recreation. Two years ago, the park was closed to the public for good. Along with household garbage, industrial chemicals had for years been dumped (倾倒)in the Pinehaven landfill. These poisonous chemicals had begun to seep(渗)back up through the soil. All of Pinehaven Park had become dangerously polluted.
Last year, the fish in the Crafton River began to die. After a series of investigations(研究), it became clear that the people of Crafton City were not to blame. 100～150 miles upstream, big paper mills were dumping industrial wastes into the river. Little by little, the level of poison in the river began to rise. Finally, it became so polluted that the fish themselves could no longer survive.
Downtown Crafton used to be a quiet area. Ten years of remarkable growth changed that in a big hurry. But with Crafton City's new prosperity(繁荣)came a new problem: air pollution. And it is a serious problem. Air pollution levels in Crafton are regularly reaching those of the nation's large industrial cities.

D．Industrial growth and progress have resulted in the pollution of Crafton City's water, air, and soil.

C．About one third D．Most of it
(3)As it is used in the passage, the phrase“for good”means ________.
