四.阅读理解。(共15小题，每小题2分，满分30分)

A

Many animal and plant species have become extinct(灭绝的)and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve(保护)the natural world they inhabit(居住)is now more important than ever.

Dodo

The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.

Rhinos

The Rhino (犀牛) horn is a highly priced item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves(保护区). Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers(偷猎者) .

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain. As few as 1000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals and mad e poaching them punishable with 20 years in prison. However, The panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animals continued existence.

Whales

The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared whale sanctuaries(保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions(碰撞)with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

Tigers

The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and the Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.
