year. The gases released include carbon dioxide, a major cause of global warming.
Twenty-one nations around the world recently joined forces to better understand and prevent
greenhouse gas emissions from farms. The Global Research Alliance on Agricultural Greenhouse Gases
was launched at the United Nations conference on climate change. The meeting took place in
Copenhagen, Denmark last month.
Agricultural experts blame a number of farm activities for producing greenhouse gases. For
example, animal waste and cattle digestive systems release methane(甲烷, 沼气)gas. Fertilized soil
and the burning of crop waste also release harmful gases into the air. Experts say some methods of
farming-turning the soil to prepare for planting-also release harmful carbon dioxide.
An official of the European Commission"s Directorate General for Research says agricultural
greenhouse gas emissions can be cut. Maive Rute suggests feeding animals a diet designed to reduce
emissions.
The new agricultural research group says protecting against global warming is only part of its
purpose. It says the world also needs to develop better farming methods to feed growing populations
in poor countries.
United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural
greenhouse gas emissions and increase food production at the same time. This is why the alliance is
important for combining resources and finding new ones.
The United States Department of Agriculture will increase spending on farm emissions research by
ninety million dollars over the next four years. The total will reach one hundred and thirty million dollars.
The U. S. D. A. will share the research with other countries in the Global Research Alliance on
Agricultural Greenhouse Gases and support researchers from developing countries that belong to the
alliance. Money from the Borlaug Fellowship Program will let the researchers study agricultural climate
change with American scientists.
Mister Vilsack said that just as climate change has no borders, there should be no borders for
research.
B. changing cattle digestive systems
C. developing better farming methods
D. giving animals the food meant to produce fewer emissions
B. an agreement signed between countries
C. a program or project set up for a research
D. an organization formed for different goals
B. 220 million dollars.
C. 40 million dollars.
D. 90 million dollars.
B. introduce the Copenhagen conference held last month
C. appeal to more countries to cut agricultural emissions
D. inform readers of the major cause of global warming
a smallest output of greenhouse gas (GHG) release into the atmosphere, but specifically refers to the
greenhouse gas CO2. Recently, most of scientific and public opinion has come to the conclusion that
there is such an accumulation of GHG (especially CO2) in the atmosphere due to human-related
activities that the climate is changing. The over-concentration of these gases is producing global
warming that affects long-term climate, with negative impacts on humanity in the foreseeable future.
Globally performed LCEs therefore, are proposed as a means to avoid catastrophic climate change,
and as a forerunner to the more advanced, zero-carbon society and renewable-energy economy.
Some nations are low-carbon societies which are not heavily industrialized or populated. In order
to avoid climate change at any point in the future, all nations considered carbon-thick societies and
societies which are heavily populated, should become zero-carbon societies and economies. Several
of these countries have promised to become "low carbon" but not entirely zero carbon, and claim that
release will be cut by 100% by offsetting release rather than stopping all release. In other words, some
release will continue which will be offset, so they are not low-release.
Nations seek to become low-carbon economies as part of a national global warming
reductionstrategy. A comprehensive strategy to manage global warming is carbon neutrality,
geoengineering andadaptation to global warming.
Nuclear power, or, the proposed strategies of carbon collection and storage (CCS) have been
proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources;
there is concern, however, with the matter of spent-nuclear-fuel storage, security and the uncertainty of
costs and time needed to successfully carry out CCS worldwide and with guarantees that the stored
release will not leak into the atmosphere. Alternatively, many have proposed renewable energy should
be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this
is changing, however, since investment and production have been growing significantly in recent times.
Furthermore, regardless of the effect to the atmosphere by GHG releases, the growing issue of peak
oil may also be reason enough for a change to a LCE.
B. the over-concentration of greenhouse gases is producing global warming
C. it can avoid catastrophic climate change
D. low carbon and zero carbon nations and societies claim for it
B. pioneer
C. symbol
D. guide
B. There"s worry about spent-nuclear-fuel storage, security and the uncertainty of costs.
C. The stored release will be likely to leak into the atmosphere.
D. Renewable energy tends to become the only means to achieve a LCE.

The Millennium Seed Bank Project, run by Kew Gardens-one of the oldest botanical gardens-will
officially deposit the 24,200th species on Thursday, a pink, wild banana from China.
More than 50 countries are now on board with Kew"s giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds.Its
goal is to help protect the planet"s biodiversity during a time of climate change.
The wild banana seed is under threat of extinction (灭绝) in southwest China from agricultural
development.It is a vital food source for Asian elephants and important for growing bananas for human
consumption.
Stored at minus20 degrees centigrade, so they can last for thousands of years, the seeds await the day
that scientists hope never comes-when the species no longer exist in the wild.
It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have
already been wiped out in the wild.He estimates that between a third and a quarter will become extinct this century.
"It is urgent and it is happening now.An area, the size of England, is cleared of primary vegetation
(植被) every year." Smith said.
Because most of the world"s food and medicines come from nature, protecting wild plant species is
quite important, scientists say.There are already many other seed banks safeguarding food crops, which
only account for 0.6 percent of plant diversity.
For Kew"s next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.
B. To safeguard food crops.
C. To protect wild plants from extinction.
D. To help scientists study wild plants.
B. the climate change in this area
C. the large number of Asian elephants
D. human"s large consumption
B. India and Brazil haven"t joined in the Seed Bank Project at present
C. there is only one seed bank in the world at present
D. the wild plants in places like India and China will never die out
B. The Millennium Seed Bank Project.
C. Britain"s seed bank.
D. Kew Gardens"next goal.
B. The temperature condition of the conservative wild plant species.
C. The government"s financial support for the seed bank project.
D. Scientists"concern on the extinct wild plant species.
1981.And freezing weather is hitting the Deep South,including Florida"s orange groves and beaches.
Whatever happened to global warming?
Such weather doesn"t seem to fit with warnings from scientists that the Earth is warming because of
greenhouse gases. But experts say the cold snap doesn"t contradict global warming at all-it"s just a
temporary phenomenon in the longterm heating trend."It"s part of natural variability," said Gerald Meehl,
a senior scientist.With global warming,he said,"we"ll still have record cold temperatures.We"ll just have
fewer of them."
Scientists say manmade climate change does have the potential to cause more frequent and more
severe weather extremes.But experts did not connect the current cold snap to climate change.
So what is going on?
" We basically have seen just a big outbreak of Arctic air over populated areas of the Northern
Hemisphere",Arndt said.
In the atmosphere,large rivers of air travel roughly west to east around the globe between the Arctic
and the tropics.This air flow acts like a fence to keep Arctic air restricted.But recently,this air flow has
become bent into a zigzag (之字形) pattern,wandering north and south.If you live in a place where it
brings air up from the south,you get warm weather. In fact, record highs were reported this week in
Washington state and Alaska.
But in the eastern United States,like some other unlucky parts of the globe,Arctic air is coming from the north. And that"s how you get a temperature of 3 degrees in Beijing, a reading of minus 42 in mainland
Norway,and 18 inches of snow in parts of Britain.The zigzag pattern arises naturally from time to time,but
it is not clear why it"s so strong right now.
B．We"ll still have record cold temperatures
C．The air flow has become a zigzag pattern
D．Cold snap doesn"t contradict global warming
B．have more hot temperatures forever
C．never experience cold temperatures
D．have more cold temperatures
B．is not related to the climate change
C．shows that the climate will turn cold
D．is affected by global warming
B．a cooling trend in climate
C．a big outbreak of Arctic air
D．its large population
B．the zigzag pattern arises naturally accidentally
C．Beijing will get cold weather next year
D．Washington state and Alaska will not face cold weather next year
