Passage Two
The earliest immigrants to North America found Indians already living there. The Indians numbered about 500,000 at that time. Their society was a primitive society, but they lived peacefully and welcomed the white strangers to the land. However, these early immigrants from Europe didn't want to share the land with the natives. They killed off many of the Indians, seized their land or pushed them off to lands farther away. Today the Indians, not more than halfa million, live in poverty and misery on the land on which they were once masters.
The earliest immigrants were the Spanish, who settled in the southern part of what is now the US The next large group were the English, after the English came the French, Dutch, Irish, Germans, and other nationality groups, mostly European.
Another early group to arrive were the Negroes. But they were brought in as slaves from Africa. They didn't win freedom till generations later.
40. Who were the earliest people living in North America?
A. The Spanish.
B. The English.
C. The Negroes.
D. The Indians.

(27) When the Europeans came to the New World, the Indians, at first, taught the settlers how to plant corn, bake fish, make canoes and smoke tobacco. In return, the whites introduced horses, guns, gun-powder and alcohol. But at last, there were struggles for land, and the struggles could have only one result-war. When the wars were over, all Indians were moved to large tracts of land called reservations. Now, some of them, embittered by past mistreatment, are determined to preserve their tribal life; some wish to modernize the reservations. These alternatives, with many variations, are what most Indians have chosen-a future in modern technology and education, or the revival of ancient tradition and treaties.
The Indians entered North America______.
A.with Columbus
B.before Columbus did
C.after Columbus' arrival
D.in the 18th century

American Dreams
There is a common response to America among foreign writers:the US is a land of extremes where the best of things qre just as easily found as the worst.This is a cliche(陈词滥调).
In the land of black and white,people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world.But the American Dream offers a way out to everyone.(46) No class system or govemment stands in the way.
Sadly,this old argument is no longer true.Over the past few decades there has been a fundamental shift in the structure of the American economy.
The gap between the rich and the poor has widened and widened.(47)
Over the past 25 years the median US family income has gone up 18 per cent.For the top 1 per cent,however,it has gone up 200 per cent.Twenty-five years ago the top fifth of Americans had an average income 6.7 times that of the bottom fifth.(48)
Inequalities have grown worse in different regions.In California,incomes for lower class families have fallen by 4 per cent since 1969.(49) This has led to an economy hugely in favor of a small group of very rich Americans.The wealthiest 1 per cent of households now control a third of the national wealth.There are now 37 million Americans living in poverty.At 12.7 per cent of the population,it is the highest percentage in the developed world.
Yet the tax burden on America’s rich is falling,not growing.(50) There was an economic theory holding that the rich spending more would benefit everyone as a whole.But clearly that theory has not worked in reality.
A.Nobody is poor in the US.
B.The top 0.01 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.
C.For upper class families they have risen 41 per cent.
D.Now it is 9.8 times.
E.As it does so,the possibility to cross that gap gets smaller and smaller.
F.All one has to do is to work hard and climb the ladder towards the top.

Why Buy Shade-Grown Coffee?
When people argue about whether coffee is good for health, they&39;re usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.<br>
Traditionally, coffee bushes were planted under the canopy (树冠) of taller indigenous (土生土长的) trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren&39;t any trees. With increased production come increased profits.<br>
Unfortunately, deforesting for coffee production immediately decreases local wildlife habitat.<br>
Native birds nest and hide from predators (捕食者) in the tall trees and migrating birds rest there.<br>
Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.<br>
Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade grown" and "bird friendly". Sure, these varieties might cost a little more. But we&39;re paying for the health of the birds, the land, ourselves, and the planet. I think it&39;s worth it.
What is the main idea of this passage? 查看材料
A.Farmers are changing the way they grow coffee
B.Coffee is becoming more expensive to produce
C.Shade-grow coffee is more expensive than sun-grow coffee
D.People should buy shade-grown coffee

Questions 31 to 35 are based on the following passage.
A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.
When numbers rise the extra mouths must be fed. New lands must be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates: there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of great rivers to ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to protect the food of the world.

A) there are many rich valleys and fertile plains

D) the units of land were made much larger
33. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
A) producing new strains of crops
B) irrigation and dry-farming methods
C) providing fertilizers
D) destroying pests and disease
