1、One-Room SchoolsOne-room schools are part of the heritage of the United States, and the mention of them makes people feel a longing for "the way things were." One - room schools are an endangered species (種類), however. For more than a hundred years, one - room schools have been systematically shut down and their students were sent away to centralized schools. As recently as 1930 there were 149,000 one - room schools in the United States. By 1970 there were 1,800. Today, of the nearly 800 remaining one - room schools, more than 350 are in Nebraska. The rest are spread through a few other states that have on their road maps wide - open spaces between towns.Now that there are hardly any left, educators are beginning to think that maybe there is something yet to be learned from one - room schools, something that served the pioneers that might serve as well today. Progressive educators have come up with new names like "peer - group teaching" and "multi - age grouping" for educational procedures that occur naturally in the one - room schools. In a one - room school the children teach each other because the teacher is busy part of the time teaching someone else. The fourth grader can work at the fifth grade level in math and the third grade level in English without the bad name associated with being left back or the pressures of being skipped (超過) ahead. A youngster with a learning disability can find his or her own level without being separated from other pupils. A few hours in a small school that has only one classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is that their children have to go to a one - room school.One - room schools are in danger of disappearing because ____. 【單選題】

A.there has been a trend towards centralization

B.they cannot get top students

C.they exist only in one state

D.children have to teach themselves

正確答案:A

答案解析:本題有一定的難度，考生不太好定位，需要認(rèn)真讀第一段找答案。第一段第三句談到，一百多年來，大教室學(xué)校逐漸被關(guān)閉，學(xué)生被統(tǒng)一分到政府的集中化學(xué)校，回來看選項(xiàng)，A是近義解釋，是最佳答案。做本題時(shí)可以先看選項(xiàng)，得到信息提示。

2、An Early Form of Jazz MusicMusic comes in many forms; most countries have a style of their own. At the turn of the last century, ____ jazz was born, America had no prominent music 0f its own. No one knows exactly when was invented or by whom. But it began to be heard in the early 1890s. Jazz is America\'s contribution to popular music. In contrast to classical music, which follows formal European traditions, jazz is spontaneous and free in form. It bubbles with energy, expressing the moods, interests, and emotions of the people. In the 1920s\' jazz sounded like America. And so it does today. The origins 0f the music are as interesting as the music itself. American Negroes, or blacks, as they are called today, were the jazz pioneers. They were brought to the Southern states as slaves. They were sold to plantation owners and forced to work long hours. When a Negro died, his friends and relatives formed a procession to carry to body to the cemetery. In New Orleans, a band often accompanied the body . On the way to the cemetery the band played slow, solemn music, suited to the occasion. Furthermore 0n the way home the mood changed. Spirits lifted. Death had removed one of their numbers, but the living were glad to be alive . The band played happy music, improvising on both the harmony and the melody of the tunes played at the funeral. This music made everyone want to dance. It was an early form ofjazz. 【單選題】

A.while

B.when

C.since

D.as

正確答案:B

答案解析:when jazz was born是定語從句，修飾at the turn of the last century. 所以這里需要填入的是一個(gè)引導(dǎo)定語從句的關(guān)聯(lián)副詞，只有when具有這一功能。

3、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. _____. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. . Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. This allowed scientists to gauge the pace and progress of the ecological recovery. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【單選題】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正確答案:F

答案解析:第46題前面的句子有certain species，后面的句子有still others，這一定是英語中“some/certain. …. others. …still others”的固定結(jié)構(gòu)。僅從這一點(diǎn)判斷，F(xiàn)是答案。

4、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to ____ them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【單選題】

A.move

B.force

C.turn

D.push

正確答案:C

5、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Paragraph 5 ____【單選題】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane
