An experiment was once done by Karl von Frish, in which he studied bee activities when they returned to their home called a hive (蜂房). The experiment showed that there was a means by which a bee communicated to other bees that it had found food. That was dance!
In fact, bees do two kinds of dances to tell other bees of their food discovery. First, there is a circle dance, in which the bee moves in a circle inside the hive. The circle dance is used when the food is not more than ten meters away. A second kind of dance done by the bee is a waggling (摇摆) dance. That is to say, the bee wiggles (摆动) the end of its body as it moves in a straight line, then it turns in a semicircle (半圆), runs straight again. The waggling dance is used when the food is more than ten meters away. Meanwhile, in the two dances, the bees smell the dancing bee that has found the food. The smell tells them where to find the flower and also what kind of flower to look for.
For this really interesting work, Karl von Frisch won a Nobel Prize.

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.
(2)According to the passage, what portion of the park had originally been marked for use as a garbage dump?
[ ]
A．Less than half B．Exactly half
C．About one third D．Most of it
(3)As it is used in the passage, the phrase“for good”means ________.
[ ]
