Practice 2　　The destiny of wild places in the 21 century can be read in the numbers. The pressure to exploit the world’ s remaining wilderness for natural resources, food and human habitation will become overwhelming. But bulldozers and chain saws aren’t the only threats. A new menace has emerged from the least likely quarter; in many cases, the very people who care most passionately about empty places are hastening their demise.　　Backcountry activities have become extremely trendy in the U. S., a fad that has been eagerly abetted by Madison Avenue. These days it’s impossible to turn on a television or open a magazine without being assaulted by a barrage of ads that use skillfully packaged images of wilderness activities to rev the engine of consumerism. Disconcerting though this development may be, it happens to come with a substantial upside; because wilderness is now esteemed as something precious and/or fashionable, wild places are more often being rescued from commercial exploitation. But if the wilderness fad has made it easier to protect wild country from development, it has made it harder to protect wild country from the exploding ranks of wilderness enthusiasts. Increasingly, places once considered enduringly back of beyond are now crowded with solitude seekers. As wilderness dwindles and disappears, more is at stake than the fate of endangered species. Other, less tangible things stand to be lost as well. Empty places have long served as a repository for a host of complicated yearnings and desires. As an antidote to the alienation and pervasive softness that plague modern society, there is no substitute for a trip to an untrammeled patch of backcountry, with its attendant wonders, privation and physical trials.

lease（释放）poisons that make people sick.

When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly

Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the

Human and the Earth

In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?

in terms of the evolution of life on Earth,the history of human beings is_______.
A:very short
B:very long
C:as long as that of other animals
D:as long as that of the Earth

答案：A

解析：

文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。
