4.Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions,sometimes deliberately,sometimes unconsciously.He is covering huge areas with new kinds of plants,or with houses,factories,slag-heaps and other products of his civilization.He exterminates some species on a large scale,but favors the multiplication of others.In brief,he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million.Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade,or that the provision of pot cacti for lonely settlers'wives would have led to Eastern Australian being overrun with forests of Prickly Pear?Who would have prophesied that the cutting down of forests on the Adriatic coasts,or in parts of Central Africa,could have reduced the land to a semi desert,with the very soil washed away from the bare rock?Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa,measles into Oceania,very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds,prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see,owing to some little change brought about by civilization,the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock.

A.man is covering huge areas with new kinds of plants
B.man is facilitating the spread of animals into new regions.
C.man is killing some species on a large scale

解答 26.C.细节理解题.根据第一段He is covering huge areas with new kinds of plants,or with houses,factories,slag-heaps and other products of his civilization.He exterminates some species on a large scale,but favors the multiplication of others可知反映人类改变自然平衡的例子包括用新的植物覆盖其他种类,促进动物传播到新的地区和大规模杀伤某些物种;故选C.
27.B.细节理解题.根据第二段Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade可知加拿大的一片水草导致英国的一半水道被封锁了十年;故选B.
28.C.细节理解题.根据文章Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa,measles into Oceania,very possibly malaria into ancient Greece可知改进的通信导致了疾病的传播;故选C.
29.A.细节理解题.根据文章We make a nature sanctuary for rare birds,prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested可知我们建造了一个稀有鸟类的自然保护区却导致一些普通而又易生存的鸟类大量繁殖;故选A.
30.D.推理判断题.根据文章Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions,sometimes deliberately,sometimes unconsciously可知这篇文章的主旨是人类到处都在改变着自然界的平衡;故选D.
