[解析]
(1)细节理解题。根据文章第一段中Although 25% of land is countryside,new methods of farming mean that there are fewer birds and small animals than ever before.(虽然25%的土地是农村,但新的耕作方法意味着鸟类和小动物比以往任何时候都少。)可知,新的耕作方法破坏了野生动物的生存条件,导致英国野生动物较少,故选A。
(2)词义猜测题。根据前面Some say that Britain needs to become more natural again and suggest trees and plants that once grew in Britain should be allowed to grow again.They even say that large wild animals which have not lived in Britain should be helped to return and live wild.(有人说,英国需要重新变得更加自然,并建议应该允许曾经在英国生长的树木和植物再次生长。他们甚至说,应该帮助那些没有在英国生活过的大型野生动物回归并在野外生活。)可知,有人提出要让英国再次变得更加自然,让以前在英国生活过的大型野生动物回到英国,由此推断,划线词表达的意思是"让野生动物回到英国"。A.Protecting wild animals.保护野生动物;B.Returning wild animals to Britain.让野生动物回到英国;C.Planting more green plants.种植更多的绿色植物;D.Helping wild animals live better.帮助野生动物生活得更好。B项与划线词意思接近,故选B。
(3)段落大意题。根据最后一段第一句Not everyone agrees.(不是每个人都同意),以及Some people ask if wolves will attack sheep or even humans.They are also angry that rewilding might mean an end to walking in the hills many people enjoy.(有些人问狼是否会袭击绵羊甚至人类。他们还很愤怒,认为"再野化"意味着喜爱在山坡散步的人们再也不能这么做了)可知,本段主要介绍了有些人反对"让野生动物回归英国"的提议。故选A。
(4)标题概括题。阅读全文,并根据文章第一句Britain was once covered by thick forests,home to many animals which no longer live here.(英国曾经被茂密的森林覆盖,曾是许多不再生活在这里的动物的家园),第二段第一句Some people want to change this.(有些人想改变这一点)和最后一句They call this "rewilding."(他们称之为"再野生化"),以及最后一段第一句Not everyone agrees.(不是每个人都同意)可知,本文主要介绍了英国的野生动物数量正在减少,有人提出了"让野生动物回归英国"的想法,但也有人提出异议。由此判断,选项D"让英国重新野化"可作为文章标题,故选D。
