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 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.
56. It implies that _______.
A．The Dodo lacked the ability to protect itself from other animals
B．Sailors to the
C．The Dodo used to be a strong animal that liked fighting
D． The Dodo, pigs, monkeys and rats were the natives to the

查看习题详情和答案>>A few weeks ago a group of scientists produced a report about global warming and the natural world．They wanted to find out if global warming was dangerous for plants and animals．The scientists were surprised by what they found．They say that during the next 50 years about 25% of land animals and plants will become extinct(灭绝的)．More than 1 million plant and animal species will become extinct by 2050．
The head of the research team, Christ Thomas, who is professor of conservation biology at Leeds University, said the results of their research were frightening．More than 10% of all plants and animals will become extinct．It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere．But the scientists say if we control greenhouse gases now, we could save many more plants and animals from extinction．
The scientists studied some areas of the world with a very rich biology．These areas were Europe, Australia, Central and South America, and South Africa．Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler．In flat areas, such as deserts, plants and animals would have to move very long distances to get cooler, so they are in greater danger of extinction．The scientists found many surprising things．For example, they found that half of the 24 species(物种) of butterfly they studied in Australia would soon become extinct．
64．According to this passage, global warming could be best described as ________ to many plants and animals．
A．deadly B．surprising C．disappointing D．frightening
65．What’s the purpose of the research led by Christ Thomas?
A．To protect animals and plants from global warming．
B．To call on people to control greenhouse gases．
C．To warn us of the extinction of many animals and plants．
D．To study the effects of global warming on animals and plants．
66．Why did species living in mountainous areas have a better chance of survival?
A．Mountains helped keep them out of more heating．
B．Global warming had no effect on mountainous areas．
C．There were no greenhouse gases in mountainous areas．
D．There were more water in mountains than in deserts．
67．Which of the following is NOT true?
A．It is certain that many plants and animals will die out．
B．Half of the Australian butterflies would die out．
C．Many more animals and plants still can be saved．
D．Europe is one area which has a very rich biology．
68．What can be the best title of this passage？
A．Greenhouse effect and global warming
B．Extinct animals in the world
C．A terrifying discovery concerning global warming
D．Disappearance of butterflies
