No evolutionary strategies informed them how to behave in this new landscape of mountainous pine forest unoccupied by their kind for 50 years. 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 24 hours 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 (没收)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 Trusts campaign does not attempt to discourage the practice, but rather urges people who buy parrots as pets to choose birds raised by humans.【文章大意概括】本文通过在亚利桑那州五只鹦鹉被释放的故事，说明了鹦鹉引入计划的重要性以及对鹦鹉生活习性等各方面进行研究的重要性和对鹦鹉进行研究的重要原因。1What do we know about the area where the five parrots were reintroduced?A. Its landscape is new to parrots of their kind.B. It used to be home to parrots of their kind.C. It is close to where they had been kept.D. Pine trees were planted to attract birds.【详解剖析】事实细节题。根据第一段第二句：这五只鹦鹉未被教过如何在这个新地方生活；这片松林山区50年来未被这种鹦鹉占据过(50年前有过)。可知，五只鹦鹉被引入的地方曾经是鹦鹉的家园或繁衍之地。【最佳选项】B2The reintroducing experience three years ago shows that manraised parrots_.A. can find their way back home in JerseyB. are unable to recognize their parentsC. are unable to adapt to the wildD. can produce a new species【详解剖析】推理判断题。根据第一、二段，特别是信息句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.可以推测出，人工喂养的鹦鹉不能适应野外的生存环境。【最佳选项】C3Why are researches on parrots important according to the passage?A. The Trust shows great concern for the programme.B. We need to know more about how to preserve parrots.C. Many people are interested in collecting parrots.D. Parrots intelligence may some day benefit people.【详解剖析】推理判断题。最后一段就是信息提示。主要表达了对鹦鹉进行研究的重要性，主要表现在两个方面：我们必须了解鹦鹉在自然条件下如何生存；其次，我们需要更多地了解宠物鹦鹉的需要，督促那些买鹦鹉当宠物的人选择人工培育的鹦鹉。从而判断，本题主要表达我们如何保护鹦鹉的问题。【最佳选项】B4According to the passage, people are advised_.A. to treat wild and caged parrots equallyB. to set up comfortable homes for parrotsC. not to keep wild parrots as petsD. not to let more parrots go to the wild【详解剖析】推理判断题。由最后一段特别
