阅读下列短文，从每小题所给的四个选项中，选出最佳选项。
At the Sydney Olympic in 2000 there were eight diving events for men and women. In these events, individual and synchronized (双人同步的) competitors performed a set number of compulsory and voluntary dives, each of which was given a point score.
Platform
The platform is a non - bending board 10m high - the same height as a three - story building.
Springboard
On the 3m springboard, divers need ability and timing. They use the flex of the board to attain maximum spring.
Judges
Seven judges give each dive a score out of ten. A dive is judged by the approach, take - off, elevation (高度), execution (实施、完成) of movements and entry into water.
Scoring
The highest and lowest scores are got rid of and the remaining five are totaled. The number is mulitiplied by the degree of difficulty rating assigned to each dive. This total is then mulitplied by 0.6 to give the final score.
Competition
When there are more than 16 competitors, a preliminary competition is held. The eight divers with the most points qualify (合格) for the final.
Types of Dives
There are six different groups of dives. Forward, backward, reverse (向后的) and inward dives involve rotating in different directions relative to the board and the starting position. Twisting (旋转) includes any dive with a twist. Armstand dives begin with a handstand position on the edge of the platform.
Body positons
Tuck - The body is bent at the waist and knees, the thighs are drawn to the chest while the heels are close to the buttocks (臀部).
Pike - The legs are straight with the body bent at the waist. The arm position is dictated by the particular dive.
Straight - No bending at the waist or knees is permitted.
Free - The free position is only used in dives that include twists.
Synchronized Diving
Pairs of dives perform a combination of dives at the same time. Nine judges award points with four judges rating the execution of the dives and other five assessing the synchronization (一致，同步) of the two divers.

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 ________.
