The review study,"Organic Agriculture in the 21st Century,”is featured as the cover story for theFebruary issue of the journal Nature Plants. It is the first to compare organic and conventional agricultureacross the main goals of sustainability identified by the National Academy of Sciences: productivity,economics，and environment.
Critics have long argued that organic agriculture is inefficient，requiring more land to yield the sameamount of food. It's true that organic farming produces lower yields，averaging 10 to 20 percent less thanconventional. Advocates contend that the environmental advantages of organic agriculture far outweighthe lower yields，and that increasing research and breeding resources for organic systems would reduce theyield gap.Sometimes excluded from these arguments is the fact that we already produce enough food tomore than feed the world's 7.4 billion people but do not provide adequate access to all individuals
In some cases，organic yields can be higher than conventional. For example，in severe droughtconditions，which are expected to increase with climate change in many areas，organic farms can produceas good，if not better，yields because of the higher water-holding capacity of organically farmed soils.
What science does tell us is that mainstream conventional farming systems have provided growingsupplies of food and other products but often at the expense of other sustainability goals.
Conventional agriculture may produce more food，but it often comes at a cost to the environment.Biodiversity loss，environmental degradation，and severe impacts on ecosystem services have not onlyaccompanied conventional farming systems but have often extended well beyond their field boundaries.With organic agriculture，environmental costs tend to be lower and the benefits greater.
Overall，organic farms tend to store more soil carbon，have better soil quality， and reduce soil erosioncompared to their conventional counterparts. Organic agriculture also creates less soil and water pollutionand lower greenhouse gas emissions. And it's more energy-efficient because it doesn't rely on syntheticfertilizers or pesticides.
Organic agriculture is also associated with greater biodiversity of plants，animals，insects andmicroorganisms as well as genetic diversity. Biodiversity increases the services that nature provides andimproves the ability of farming systems to adapt to changing conditions.
Despite lower yields，organic agriculture is more profitable for farmers because consumers are willingto pay more.Higher prices，called price premiums，can be justified as a way to compensate farmers forproviding ecosystem services and avoiding environmental damage or external costs.
51. What do we learn from the conclusion of the author's review study？
A)More resources should be tapped for feeding the world's population.
B)Organic farming may be exploited to solve the global food problem.
C)The long-term prospects of organic farming are yet to be explored.
D) Organic farming is at least as promising as conventional farming.
52. What is the critics' argument against organic farming？
A)It cannot meet the need for food.
B) It cannot increase farm yields.
C )It is not really practical.
D) It is not that productive.
53. What does the author think should be taken into account in arguing about organic farming？
A)Growth in world population.
B)Deterioration in soil fertility.
C) Inequality in food distribution.
D)Advance in farming technology.
54. What does science tell us about conventional farming？
A) It will not be able to meet global food demand.
B)It is not conducive to sustainable development.
C) It will eventually give way to organic farming.
D) It is going mainstream throughout the world.
55. Why does the author think higher prices of organic farm produce are justifiable？
A)They give farmers going organic a big competitive edge.
B)They motivate farmers to upgrade farming technology.
C) Organic farming costs more than conventional farming.
D)Organic farming does long-term good to the ecosystem.

In the early decades of the United States. the agrarian movement promoted the farmer
as society's hero. In the minds of agrarian thinkers and writers. the farmer was a person on whose
well-being the health of the new country depended. The period between the
Revolution, which ended in 1783,and the Civil War. which ended in 1865.was the age of
(5) the farmer in the United States. Agrarian philosophers. represented most eloquently by
Thomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a good
society, their political virtue. and their Superior morality. And visually all policy makers, whether
they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as
the key component of the American economy. Consequently, government at
(10)all levels worked to encourage farmers as a social group and agriculture as economic
enterprise.
Both the national and state governments developed transportation infrastructure, building
canals, roads, bridges, and railroads, deepening harbors, and removing obstructions from navigable
streams. The national government imported plant and animal varieties and
(15)launched exploring expeditions into prospective farmlands in the West. In addition,
government trade policies facilitated the exporting of agricultural products.
For their part. farmers seemed to meet the social expectations agrarian philosophers
had for them. as their broader horizons and greater self-respect, both products of the
Revolution were reflected to some degree in their behavior. Farmers seemed to become
(20)more scientific.joining agricultural societies and reading the farm newspapers that sprang
up throughout the country. They began using improved implements, tried new crops and
pure animal breeds, and became more receptive to modern theories of soil improvement.
They also responded to inducements by national and state governments. Farmers
streamed to the West. filling frontier lands with stunning rapidity. But farmers responded
(25)less to the expectations of agrarians and government inducements than to growing market
opportunities. European demand for food from the United States seemed insatiable. War,
industrialization, and urbanization all kept demand high in Europe. United States cities
and industries grew as well; even industries not directly related to farming thrived because
of the market, money. and labor that agriculture provided.
What does the passage mainly discuss？
A．The agrarian philosophy of Thomas Jefferson
B．The role of the national government in the development of agriculture
C．Improvements in farming techniques
D．The impact of the increased importance of the farmer

In agriculture, the transformation was marked by the emergence of the grain elevators, the cotton presses, the warehouses, and the commodity exchanges that seemed to so many of the nation's farmers the visible sign of a vast conspiracy against them. In manufacturing, the transformation was marked by the emergence of a "new factory system" in which plants became larger, more complex, and more systematically organized and managed. And in distribution, the transformation was marked by the emergence of the jobber(中间商), the wholesaler, and 'the mass retailer(零售商). These changes radically altered the nature of work during the half century between 1870 and 1920.
To be sure, there were still small workshops, where skilled craftspeople manufactured products ranging from newspapers to cabinets to plumbing fixtures. There were the sweatshops in city tenements, where groups of men and women in household settings manufactured clothing or cigars on a piecework basis. And there were factories in occupations such as metalwork where individual contractors presided over what were essentially handicraft proprietorships that coexisted within a single building. But as the number of wage earners in manufacturing rose from 2.7 million in 1888 to 4.5 million in 1900 to 8.4 million in 1920, the number of huge plants like the Baldwin Locomotive Works in Philadelphia burgeoned (迅速成长), as did the size of average plant. (The Baldwin Works had 600 employees in 1855, 3,000 in 1875, and 8,000 in 1900.) By 1920, at least in the northeastern United States where most of the nation's manufacturing wage earners were concentrated, three-quarters of those worked in factories with more than 100 employees and 30 percent worked in factories with more than 100 employees.
What can be inferred from the passage about the agricultural sector of the economy after the Civil War？______
A．New technological developments had little effect on farmers
B．The percentage of the total population working in agriculture declined
C．Many farms destroyed in the war were rebuilt after the war
D．Farmers achieved new, prosperity because of better rural transportation
