共用题干第一篇Preserving Nature for FutureDemands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe.Studies by the Council of Europe,of which 21 countries are members , have shown that 45 per cent of reptile（爬行动物）species and 24 per cent of butterflies（蝴蝶）are in danger of dying out.European concern for wildlife was outlined by Dr.Peter Baum,an expert in the environment and natural resources division of the council,when he spoke at a conferencearranged by the administrators of a British national park.The park is one of the few areas in Europe to hold the council's diploma（证书）for nature reserves (自然保护区) of the highestquality ,and Dr.Baum had come to present it to the park once again.He was afraid that public opinion was turning against national parks,and that those set up in the 1960s and1970s could not be set up today.But Dr.Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right."No area could be expected to survive both as a true nature reserve and as a touristattraction,"he went on.The short-sighted view that reserves had to serve immediate human demands for outdoor recreation（户外娱乐）should be replaced by full acceptanceof their importance as places to preserve nature for the future."We forget that they are the guarantee of life systems,on which any built-up area ultimately depends,"Dr.Baum went on."We could manage without most industrial products,but we could not manage without nature.However,our natural environment areas, which are the original parts of our countryside, have shrunk（缩小）to become mere islands in a spoiled and highly polluted land mass."Why did Dr.Baum come to a British national park?A:Because he needed to present it with a council's diploma.B:Because he was concerned about its management.C:Because it was the only national park of its kind in Europe.D:Because it had never before received a diploma from the Council.
