题目内容
17．Running like the wind，roaring 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 30wild 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 4000tigers 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 2007when the reservations in Fujian are ready．
71．What is the main reason for the South China tiger becoming one of the world's top ten most endangered species？D
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．
72．How is the programme of sending several tigers to South Africa getting on？C
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．
73．By saying"but they are nothing like their wild cousins"，the writer means thatB．
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
74．What is the purpose of sending young tigers to South Africa？A
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．
75．Which one is not the reason for South Africa being chosen as the training place？A
A．Because the tigers can hunt wild animals by themselves at the African base．
B．Because South Africans are skilled at dealing with the tigers．
C．Because there is a complete eco-chain and enough space there．
D．Because the country has good natural conditions for the tigers to learn in．
分析 本文叙述的是华南虎濒临灭绝的主要原因是栖息地遭到破坏并且捕猎行为没有得到控制，并讨论了如何保护华南虎及已经采取的措施．
解答 71-75 DCBAA
71．D 细节题．由第三段第三句"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．"可知，栖息地遭到破坏并且捕猎行为没有得到控制，是华南虎濒临灭绝的主要原因．故正确答案为D．
72．C 细节题．由第六段第三句"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，两只大一点的老虎已经恢复了一些捕食野生动物的本能．故正确答案为C．
73．B 细节题．题干中的句子出现在第四段第二句，由其后一句"They have lost their natural skills such as hunting and killing"可知这些饲养在动物园中的老虎并不像那些野生的老虎一样拥有狩猎或者猎杀的技能．故正确答案为B．
74．A 细节题．由第六段第一句"To reintroduce the species into the wild，the country started a programme to send five to ten young tigers to South Africa．"可知，为让这些老虎重新学会野外生存的技能，中国启动了一个项目将老虎们送往南非．故正确答案为A．
75．A 细节题．B项，由倒数第二段第一句"South Africans are very experienced in reintroducing big animals to the wild．"可知，南非在帮助动物们恢复野性方面很有经验，所以B项是原因之一．C项，由倒数第二段最后一句"We tried in Fujian Province，but it was not successful as there was not a complete ecochain（生物链） and there was a lack of space．"可知，福建没有成为培训基地的原因是那里没有完整的生物链也没有足够的空间，由此可推测南非被选为培训基地自然是能满足这两项要求的，所以C项是原因之一．D项，由倒数第二段第二句"The country has very good natural conditions for the tigers to learn in"可知D项是原因之一．唯独A项在文中并未提及，故正确答案为A．
点评 做阅读时经常犯错的主要原因是，仅凭读过文章后残留在脑海中的一丝印象来勾选答案，这样便很容易掉入出题人故意设布下的题目陷阱．所谓阅读理解，对于题目的理解一定要忠实于原文，因此，每一道题都应该与原文作全面的对比与核查，再得出答案．也就是说，阅读理解的每一道题目，在原文都应该有明确的出处，我们把这一出处叫做原文相关句，（1）排除与原文相关句主题不一致的选项（2）排除与原文相关句态度相反的选项 （3）排除用于过于极端或负面的选项（4）注意结合文章主旨和主题去排除．
