Newcomers
When a country is under-populated, newcomers are not competitors, hut assistants. If more come they may produce not only new quotas, but a surplus as well. In such a state of things land is (51) and cheap. The possession of it (52) no power or privilege. No one will work for another for wages (53) he can take up new land and be his own master. Hence it will pay no one to own more land than he can cultivate by his own labor, or with such aid as his own family (54) . Hence, again, land (55) little or no rent; there will be no landlords living on rent and no laborers living on (56) , but only a middle class of yeoman farmers(自耕农). All are (57) on an equality, and democracy becomes the political form, because this is the only state of society in which equality, on which democracy is based, is realized as a fact. The same effects are powerfully (58) by other facts. In a new and under-populated country the industries which are most profitable are the extractive industries. The (59) of these, with the exception of some kinds of mining, is that they call (60) only a low organization of labor and small amount of cap ital. Hence they allow the workman to become (61) his own master, and they educate him to freedom, independence, and self reliance. At the same time, the social groups being only (62) marked off from each other, it is easy to (63) from one class of occupations, and consequently from one social grade, to another. Finally, under the same circumstances, education, skill, and superior training have but inferior value compared with what they have in (64) populated countries. The (65) lie in an under-populated country, with the coarse, unskilled, manual occupations, and not with the highest developments of science, literature, and art.
(51)
A．scarce
B．sacred
C．abundant
D．extractive

听力原文： Forests are of great importance to our environment because they can absorb carbon dioxide and produce oxygen. They may also provide shelter and food for many different types of plants and animals. Trees are cut down for many reasons but the main reasons are to make space to build new houses and to clear land to grow grass for cows and sheep to eat, to produce dairy foods. The trees being cut down are sold and are made into paper and furniture.
Cutting down trees may have serious effects to the environment. (33)If animals' homes, which are built in and around the trees, are destroyed, many species in the world will become extinct. For example, many different types of animals in South America had disappeared before scientists could learn about them. Cutting down trees also affects the climate. When rain falls on a forest, new clouds will be created. If huge areas of trees are cut down, clouds can not form, rain does not fall and the land becomes drier and drier and finally becomes deserts. (34)And what's more, the carbon dioxide builds up and adds to the global warming which is making the earth become hotter and hotter.
(35)In recent years, to protect the forests, many European countries are planting trees faster than they are cutting them down. Many trees were planted a few years ago to replace woodland and to create forests in areas where there wasn't much wood. We can also help to save forests by reusing and recycling paper.
(34)
A．The loss of natural habitat for many species.
B．Less space for building new homes.
C．Less carbon dioxide and oxygen.
D．Reduced supply of paper and wood.

听力原文： Millions of years ago, whales lived on land and walked on four legs. Today, whales still have small bones that are the remains of their hind legs, but these bones can only be seen on the inside of the whale. No one knows why whales left the land to live in the water.
However, scientists can imagine that when the whales changed their environment, their bodies underwent a change—taking on a more fish-like appearance. This new form. offered less resistance to the water, enabling the whales to swim faster.
Despite their fish like form, whales are not fish. A whale will drown, just as a man will, if it stays under water too long. When a whale is under water, it closes its nostrils tightly and holds its breath. The air in its lungs becomes very hot and full of water vapor. When the whale rises to the surface and exhales, its hot breath produces a column of water vapor that rises high in the air. A man produces the same effect when he exhales warm air on a cold morning.
Whales are classified as mammals because they bear their young, rather than laying eggs, and because the mother whales give the babies milk. Like other mammals, whales have warm blood. Their blood stays at the same temperature, even when they move from hot to cold water. They keep warm in cold water because they have a thick layer of fat just under their skins. This fat is called blubber, and it is thicker on whales that spend their lives in cold water. Almost all land mammals, except man, have hair on their bodies to keep them warm, but whales, which have very few hairs, are kept warm by their fat.
How does a whale keep itself warm？
A．By its thick layer of fat under its skin.
B．By moving frequently in the water.
C．By adjusting its blood temperature.
D．By taking in hot air.
