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(生物鏈) 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(chǎn) 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 本文敘述的是華南虎瀕臨滅絕的主要原因是棲息地遭到破壞并且捕獵行為沒有得到控制,并討論了如何保護(hù)華南虎及已經(jīng)采取的措施.
解答 71-75 DCBAA
71.D 細(xì)節(jié)題.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,棲息地遭到破壞并且捕獵行為沒有得到控制,是華南虎瀕臨滅絕的主要原因.故正確答案為D.
72.C 細(xì)節(jié)題.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,兩只大一點的老虎已經(jīng)恢復(fù)了一些捕食野生動物的本能.故正確答案為C.
73.B 細(xì)節(jié)題.題干中的句子出現(xiàn)在第四段第二句,由其后一句"They have lost their natural skills such as hunting and killing"可知這些飼養(yǎng)在動物園中的老虎并不像那些野生的老虎一樣擁有狩獵或者獵殺的技能.故正確答案為B.
74.A 細(xì)節(jié)題.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,為讓這些老虎重新學(xué)會野外生存的技能,中國啟動了一個項目將老虎們送往南非.故正確答案為A.
75.A 細(xì)節(jié)題.B項,由倒數(shù)第二段第一句"South Africans are very experienced in reintroducing big animals to the wild."可知,南非在幫助動物們恢復(fù)野性方面很有經(jīng)驗,所以B項是原因之一.C項,由倒數(shù)第二段最后一句"We tried in Fujian Province,but it was not successful as there was not a complete ecochain(生物鏈) and there was a lack of space."可知,福建沒有成為培訓(xùn)基地的原因是那里沒有完整的生物鏈也沒有足夠的空間,由此可推測南非被選為培訓(xùn)基地自然是能滿足這兩項要求的,所以C項是原因之一.D項,由倒數(shù)第二段第二句"The country has very good natural conditions for the tigers to learn in"可知D項是原因之一.唯獨A項在文中并未提及,故正確答案為A.
點評 做閱讀時經(jīng)常犯錯的主要原因是,僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案,這樣便很容易掉入出題人故意設(shè)布下的題目陷阱.所謂閱讀理解,對于題目的理解一定要忠實于原文,因此,每一道題都應(yīng)該與原文作全面的對比與核查,再得出答案.也就是說,閱讀理解的每一道題目,在原文都應(yīng)該有明確的出處,我們把這一出處叫做原文相關(guān)句,(1)排除與原文相關(guān)句主題不一致的選項(2)排除與原文相關(guān)句態(tài)度相反的選項 (3)排除用于過于極端或負(fù)面的選項(4)注意結(jié)合文章主旨和主題去排除.
