Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.
Sixty?six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.
“Breeding has damaged the quality of the species”, said Pei Enle, deputy director of the Shanghai Zoo.
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.
“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”, said Lu Jun, office director of the National Wildlife Research and Development Center. “We tried in Fujian Province, but it was not successful as there was not a complete eco?chain(生物链) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.
1.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
A. Because it has lost its natural instincts.
B. Because there is not a complete eco?chain.
C. Because there is no space for it.
D .Because uncontrolled hunting has destroyed its natural living conditions.
2.How is the programme of sending several tigers to South Africa getting on?
A. Its effect still remains to be seen.
B. Two tigers can already compete with their wild cousins.
C. Some of the tigers are already on the road to recovering their natural skills.
D. The tigers should be able to recover their instincts completely by 2007.
3.By saying “but they are nothing like their wild cousins”, the writer means that________.
A. they are no longer feared by other wild animals
B. they don't know how to hunt or kill
C. a complete change has resulted in the species because of breeding
D. to reintroduce them into the wild has become an urgent task
4.What is the purpose of sending young tigers to South Africa?
A. To help the tigers recover their ability to live in the wild.
B. To provide them with a better environment.
C. To get the tigers to go on a tour.
D. To find a complete eco?chain for them.

试题分析: 本文是一篇说明文，介绍了华南虎濒临灭绝的状况以及对此政府采取的措施。由于栖息环境遭到破坏，加上捕杀泛滥，华南虎数量急剧减少，已不足30头。中国政府已经启动了一项计划，把五至十头老虎放到南非的自然环境中，增加野生老虎的数量。
1.细节理解题。根据第三段“But due to the destruction of their natural habitat and uncontrolled hunting,”可知，自然生活环境的破坏和滥杀，导致华南虎数量急剧下降，选D。
2.细节理解题。根据倒数第三段“Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.”可知，有两只较年长的老虎已经恢复了一些本能，并且能独立捕捉猎物，故选C。
3.推理判断题。根据第四段“They have lost their natural skills such as hunting and killing.”可知，关在动物园笼子里的老虎已经失去了猎杀的能力，如果放回大自然，它们将不会自己捕食猎物，故选B
4.细节理解题。根据倒数第二段“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”,可知，南非有着让大型动物重获本能的自然环境，适合老虎在那里练习捕食技能，选A。

应用题作业本系列答案By the mid?nineteenth century, the term “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in places like hotels and hospitals, and by some forward?looking city businessmen in fresh meat, fresh fish, and butter. After the Civil War (1861～1865 ), it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one?third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, early form of the modern refrigerator，had been invented.
Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, people only had some simple and basic knowledge of the physics of heat. The common idea that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Early efforts to save ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance needed for an efficient icebox.
But as early as 1803, a Maryland farmer, Thomas Moore, had been in the correct direction. He owned a farm and used an icebox of his own design for the transportation of his butter to a market in the village of Georgetown. And there he found that customers would pass up the rapidly melting goods of his competitors to pay a higher price for his butter, still fresh and hard in neat, one?pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.As a result，Moore managed to earn a large sum of money.
