19.Three years ago,five parrots were set free in a world place of Arizona,thousands of miles from the Channel Islands in Jersey where they had been looked after by zookeepers.No evolutionary strategies informed them how to behave in this new landscape of mountainous pine forest unoccupied by their kind for 50years.To the researchers'surprise,they failed to make contact with a group of wild parrots imported from Mexico and set free at the same time.Within 24hours the reintroducing ended in failure,and the poor birds were back in cages,on their way to the safety of the Arizona reintroduction programme.
Ever since then,the programme has enjoyed great success,mainly because the birds now being set free are Mexican birds illegally caught in the wild,confiscated (沒收)on arrival north of the border,and raised by their parents in the safety of the programme.The experience shows how little we know about the behaviour and psychology (心理)of parrots,as Peter Bennett,a bird researcher,points out:"Reintroducing species of high intelligence like parrots is a lot more difficult.People like parrots,always treating them as nothing more than pets or valuable‘collectables'."
Now that many species of parrot are in immediate danger of dying out,biologists are working together to study the natural history and the behaviour of this family of birds.Last year was an important turning point:conservationists founded the World Parrot Trust,based at Hayle in Cornwall,to support research into both wild and caged birds.
Research on parrots is vital for two reasons.First,as the Arizona programme showed,when reintroducing parrots to the wild,we need to be aware of what the birds must know if they are to survive in their natural home.We also need to learn more about the needs of parrots kept as pets,particularly as the Trust's campaign does not attempt to discourage the practice,but rather urges people who buy parrots as pets to choose birds raised by humans.

分析 本文主要講述對被釋放的鸚鵡的研究,以及他們數(shù)量減少的原因.
解答 BCBC
5 B 細節(jié)推理題.根據(jù)第1段where they had been looked after by zookeepers及…unoccupied by their kind for 50 years可知放生地是原先這些鸚鵡曾生活的但已有50年沒有同類鸚鵡生存的地方,應選擇B.
6 C 推理判斷題.根據(jù)第1段的描述,將這些鸚鵡放生到它們原先生活的地方,但它們卻不能適應這些環(huán)境了,應選擇C.A"能找到返回澤西的路",B"不能認出自己的父母",D"能生產新的品種"都不合文章本意.
7 B 細節(jié)理解題.根據(jù)第4段Research on parrots is vital for two reasons.…we need to be aware of what the birds must know if they are to survive in their natural home.可知對鸚鵡研究的重要性首先體現(xiàn)在需要了解更多怎樣讓鸚鵡在野生地生活的常識.選項B符合所提問題.其它選項都不符合文意.故選B.
8 C 推理判斷題.根據(jù)最后一段not attempt to discourage the practice,but rather urges…可知不提倡將鸚鵡作為寵物飼養(yǎng).故選C.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
