第1题：

The loss of biological diversity has become most spectacularly noticeable in extinction or decline of populations of large and well-known animals.Many animal species have become extinct since the 1700’s, among them the California grizzly bear, the dodo, and the passenger pigeon.Hundreds of other animal species are threatened.In North America, endangered species include the black-footed ferret, the California condor, the desert tortoise, and the whooping crane.

Most species in danger of extinction anywhere in the world are suffering from the intrusion (侵入) of human beings.The Asian elephant, for example, has become an endangered species due to the expansion of the human population throughout its range in southern Asia.In Africa, the African elephants are being killed off for their tusks.Monkeys and other primates throughout the world are threatened by hunting, capture for medical use, and the destruction of their habitats.And the rhinoceroses, lions, and other large mammals of the African savanna (grassy plains with scattered trees) compete for land and life with some of the most rapidly growing human populations in the world.

The loss of biological diversity is most severe, however, in the tropical rain forests.The forests of the tropics are particularly vulnerable to disturbance because the soils have a low capacity for retaining nutrients.Most of the forests’ nutrient elements are held in the tissues of plants.When loggers and farmers destroy existing plant cover, the nutrients are washed from the land into streams, and the land itself becomes less able to support life.Destruction of these forests destroys the habitat of hundreds, sometimes thousands, of species from such creatures as the howler monkey and indigo macaw, to less visible species of plants, insects, and microbes, many of which are not yet known to science.

1.The author points out that species extinction ().

A.is most noticeable in North America

B.is mainly taking place among large animals

C.quickened with industrialization of the society

D.never took place before the 1700’s

2.Which of the following is NOT mentioned with regard to human intrusion?

A.Elephants are killed off for their tusks

B.Some primates are hunted for medical use

C.Growing human population results in the competition for land and life among animals

D.Men live increasingly on animals as their source of food.

3.The chief cause of the gradual disappearance of biological diversity is ().

A.human cruelty

B.human interference

C.the increase of human population

D.the disappearance of the forests

4.In tropical forests，().

A.animals live a hard life due to competition

B.a lot of species die out for lack of food

C.rains constitute the major threat to species

D.a greater number of animals are yet to be known

5.It can be inferred that species extinction ().

A.proceeds of a faster rate than noticeable

B.is the worst among well-known animals

C.is the most severe in Africa

D.is chiefly due to competition among species

Text 4

The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where government is spending a great deal of money and is working hard to help discover the answer to these two questions:

1. Can we predict earthquakes?

2. Can we control earthquakes?

To answer the first question, scientists are looking very closely at the most active fault systems in the country, such as the San Andreas fault in California. A fault is a break between two sections of the earth's surface. These breaks between sections are the places where earthquakes occur.

Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately and the control of earthquakes is even farther away.

Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was pat into a layer of rocks 4,000 metres below the surface of the ground. Shortly after this injection of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. When the water" oiled" the fault, the fault became slippery and the energy of an earthquake was released.

Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this knowledge to prevent very big, destructive earthquakes, that is, scientists Could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes.

36. Earthquake belts are ______.

A) maps that show where earthquakes are likely to occur

B) zones with a high probability of earthquakes

C) breaks between two sections of the earth's surface

D) the two layers of earth along a fault

To Survive or to Vanish

1.Over 3.6 billion years ago,the first creature was born in the world.Since then,the earth started its era with life.The history of life on earth has been a history of interaction between living things and their surroundings.To a large extent,the physical form and the habits of the earth's vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time,the opposite effect,in which life actually modifies its surroundings,has been relatively slight. Only in the present century has one species一man acquired significant power to alter the nature of his world.
2.During the past 25 years,this power has not only become increasingly great but it has changed in character. The most alarming of all man's assaults upon the environment is the contamination of air,earth,rivers,and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable.In this now universal contamination of the environment,chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil,entering into living organisms, passing from one to another in a chain of poisoning and death.Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation,sicken cattle,and work unknown harm on those who drink from once pure wells."Man can hardly even recognize the devils of his own creation,"as a scientist has said.
3.Hundreds of millions of years have passed before the globe produced the life that now inhabits the earth.Given time not in years but in millennia life adjusts,and a balance has been reached.But in the modern world there is no time.
4.The quick steps of change follows the impetuous pace of man rather than the deliberate pace of nature.Radiation is now the unnatural creation of man's tampering with the atom.The chemicals are the synthetic creations of man's inventive mind,having no counterparts in nature.
5.To survive these chemicals would require not merely the years of one man's life but the life of generations.And even this,were it by some miracle possible,would be futile,for the new chemicals come from our laboratories in an endless stream;almost five hundred annually find their way into actual use in the United States alone.Among them are many that are used in man's war against nature.Since the mid l940's over 200 basic chemicals have been created for use in killing insects,weeds,and other organisms described as"pests".
6.It is not my contention that chemical insecticides must never he used.I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons,without their consent and often without their knowledge.I contend,furthermore,that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil,water,wildlife,and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.

The effect of life modifying its surroundings has been_______.
A:man's tampering with the atom
B:enormous numbers of people to contact with these poisons
C:the integrity of the natural world that supports all life
D:inventive
E:irrecoverable
F:relatively slight

答案：F
解析：
