8.The Scottish countryside will soon be home to creatures which are strange to Britain.This spring,17beavers will be released into a remote area of rivers and forests.Hunted to die out throughout Europe,beavers haven't roamedin Britain's wilderness for almost 500years.Ecologists would like to invite back other long-lost animals to help recover the natural balance.To save the country's plants from deer,which have doubled to 2million since the start of this decade,an Oxford University biologist late last year called for introducing the lynx(猞猁) that died out in Britain 1,300years ago.
Nature has long been a popular cause in Europe.British people love their countryside of fences and fields,and the Germans love their hiking forests.But in recent years people have set their sights on the more distant past,when Europe's forests were filled with elephants,rhinoceroses and big cats.Some people are even now advocating a return to the way of wilderness that dates back to the Pleistocene era,more than 11,000years ago.
Nobody is advocating allowing elephants and lions to run crazily in big cities.But supporters would give free control to a long list of small mammals,including the beaver and lynx,which some people fear could be dangerous.Some landowners are worried at the thought of beavers cutting down trees and possible floods; the Scottish parliament refused several earlier efforts to introduce the mammal.Proposals to set wolves and bears free in Britain have also met with opposition.
Although the beavers and the lynxes were popular in Europe thousands of years ago,no one is sure what effect they would have on ecosystems now."The idea of bringing back big animals is interesting,but when you take it seriously,there are a lot of questions,"say some biologists.For example,elephants could destroy what little forest and grassland Europe has left.
The beavers of Tierra del Fuego provide a lesson.When a failed commercial fur farm released its few remaining beavers into the wild 60years ago,the population exploded,and are still harming the local people.Is this Britain's future?Supporters say no,the beaver will fit right in.Destroying nature is not a job for the wild.

解答 41.A.詞義猜測(cè)題.根據(jù)文章第一段"Hunted to die out throughout Europe,beavers haven't roamedin Britain's wilderness for almost 500years"可知由于整個(gè)歐洲的捕殺,海貍已經(jīng)15年沒(méi)有進(jìn)入歐洲了;故選A.
42.B.細(xì)節(jié)理解題.根據(jù)文章第一段"To save the country's plants from deer"可知呼吁引進(jìn)猞猁的目的是可以阻止植物被鹿破壞,故選B.
43.C.細(xì)節(jié)理解題.根據(jù)文章第二段Some people are even now advocating a return to the way of wilderness that dates back to the Pleistocene era,more than 11,000years ago;可知有些人不喜歡海貍由于可能的災(zāi)難;故選C.
44.B.細(xì)節(jié)理解題,根據(jù)文章倒數(shù)第二段"The idea of bringing back big animals is interesting,but when you take it seriously,there are a lot of questions"可知生物學(xué)家們認(rèn)為把他們帶回來(lái)不是一件容易的事;故選B.
45.B.推理判斷題,根據(jù)文章最后一段"But supporters would give free control to a long list of small mammals,including the beaver and lynx",可知海貍在英國(guó)比老虎更自由;故選B.
