When global warming finally came, it stuck with a vengeance（异乎寻常地）.In some regions, t

t century, but---regardless ofwhether it is or isnt--we wont do much about it. We will argue over it and may even, as a nation, make somefairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem,the less likely they are to be observed. AI Gore calls giobal warming an "inconvenient truth," as if merely recognizing it could put us on a path to asolution. But the real truth is that we dont know enough to relieve global warming, and--without majortechnological breakthroughs--we cant do much about it. From 2003 to 2050, the worlds population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase.If energy use per person and technology remain the same, total energy use and greenhouse gas emissions(mainly CO2) will be 42% higher in 2050. But thats too low, because societies that grow richer use more energy. We need economic growth unless we condemn the worlds poor to their present poverty and freeze everyone elsesliving standards. With modest growth, energy use and greenhouse emissions more than double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricityusage, driving and travel) that might cut back global warming. Still, politicians want to show theyre "doingsomething." Consider the Kyoto Protocol(《京都议定书》). It allowed countries that joined to punish those thatdidnt. But it hasnt reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didntadopt tough enough policies to hit their 2008-2012 targets. The practical conclusion is that if global warming is a potential disaster, the only solution is new technology.Only an aggressive research and development program might find ways of breaking our dependence on fossil fuelsor dealing with it. The trouble with the global warming debate is that it has become a moral problem when its really an engineering one. The inconvenient truth is that if we dont solve the engineering problem, were helpless. What is said about global warming in the first paragraph？

A.It may not prove an environmental crisis at all.

B.It is an issue requiring worldwide commitments.

C.Serious steps have been taken to avoid or stop it.

D.Very little will be done to bring it under control.

Questionsare based on the following passage.

When you think about the growth of human population over the last century or so， it is alltoo easy to imagine it merely as an increase in the number of humans. But as we（36）， so doall the things associated with us，（37）our livestock （家畜）. At present， there are about 1.5 bil-lion cattle and domestic buffalo and about 1.7 billion sheep and goats. With pigs and poultry，they form. a（38）part of our enormous biological footprint upon this planet.

Just how enormous was not really apparent until the（39）of a new report， called "Live-stock"s Long Shadow，" by the Food and Agriculture Organisation of the United Nations.

Consider these numbers. Global livestock grazing （放牧） and feed production use "30percent of the land surface of the planet." Livestock —— which consume more food thanthey（40）—— also compete directly with humans for water. And the drive to expand grazingland destroys more biologically sensitive terrain， rain forests（41）， than anything else.

But what is even more striking， and alarming， is that livestock are（42）for about 18 per-cent of the global warming effect， more than transportation"s（43）. The culprits （罪魁祸首）are methane —— the natural result of bovine digestion —— and the nitrogen emitted by manure.

Deforestation of grazing land adds to the effect.

There are no easy trade-offs when it comes to global warming —— such as cutting back oncattle to make room for cars. The human（44）for meat is certainly not about to end anytimesoon. As "Livestock"s Long Shadow" makes clear， our health and the health of the planet de-pend on pushing livestock production in more（45）directions.

Passage 2

When you think about the growth of human population over the last century or so, it is all too easy to imagine it merely as an increase in the number of humans. But as we _1_, so do all the things associated with us, including our livestock. At present, there are about 1.5 billion _2_ and domestic buffalo and about 1.7 billion sheep and goats. With pigs and poultry, they form. a _3_ part of our enormous biological footprint upon this planet. Just how enormous was not really _4_ until the publication of a new report, called “Livestock’s Long Shadow,” by the Food and Agriculture Organization of the United Nations. Consider these numbers. Global livestock grazing and feed production use “30 percent of the land surface of the planet.” Livestock—which consume more food than they _5_—also compete directly with humans for water. And the drive to expand grazing land destroys more biologically sensitive land, rain forests _6_, than anything else. But what is even more striking, and _7_, is that livestock are responsible for about 18 percent of the global warming effect, more than transportation’s _8_. Greenhouse gases, such as methane and nitrogen，are resulted from their digestion. Grazing land, which destroys forests, adds to the effect. There are no easy trade-offs when it comes to global warming—such as cutting back on livestock to make room for care. The human _9_ for meat is certainly not about to end anytime soon. As “Livestock’s Long Shadow” makes clear, our health and the health of the planet depend on pushing livestock production in more _10_ directions.

A)yield

B)contribution

C)stain

D)ideally

E)apparent

F)multiply

G)cattle

H)passion

I)scrape

J)critical

K)liable

L)sustainable

M)deposit

N)alarming

O)especially
