Many animal and plant species have become extinct（滅絕的）and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve（保護）the natural world they inhabit（居�。﹊s 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（保護區(qū)）. Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers（偷獵者）.

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 made 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（保護區(qū)）, 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.

56. It implies that _______.

A．The Dodo lacked the ability to protect itself from other animals

B．Sailors to the Island of Mauritius lived mainly on the Dodo

C．The Dodo used to be a strong animal that liked fighting

D． The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius

57. Which group of the following animals has already ceased to exist according to the text?

A．The Dodo, Rhino and Giant Panda．

B．The Rhino, Whale and South China Tiger.

C．The Rhino, Panda, Whale and Tiger.

D．The Dodo and the Bali, Javan, and Caspian tigers.

58. ______ can serve as a cure for certain diseases.

A．The whale’s rich oil

B．The panda's black and white patched coat

C．The Rhino horn and tigers’ bones and organs

D． The Dodo’s delicious meat

59. Which of the following statements is NOT true?

A．The number of South China tigers has reached crisis point.

B．Many animals are threatened with extinction as a result of human activity.

C．People hunt for the endangered animals for high profit.

D． The Whale is the representing mark for the World Wildlife Fund．

60. What is the best title for the passage?

A. What caused the animals to go extinct?   B. Animal Conservation

C. Extinct Animals                     D. Endangered Animals

這是一篇生態(tài)類短文。文章介紹了五種比較典型的“已經(jīng)滅絕的和瀕臨滅絕的動物”并探究其原因。

56. A 推測題。從文章中的“flightless, lived off fruit fallen from the trees, easily controlled”等這些詞中可推測出Dodo鳥缺少保護自己的能力。

57. D 細節(jié)歸納題。根據(jù)文章第二段的“The population of Dodos rapidly decreased and last one was killed in 1681”一句可判斷Dodo是滅絕的動物之一，再根據(jù)最后一段中的“The Bali, Javan, and Caspian tigers are already extinct”一句可得出其他幾種。

58. C 細節(jié)理解題。文章的第三段和最后一段提到“犀牛角和虎骨及器官”有很高的藥用價值。

59. D判斷題。從第四段中的“The future of the World Wildlife Fund's symbol is far from certain. ”一句可得出“世界野生動物基金”的圖案標記是“大熊貓”，而不是“鯨”。

60. B
