Questions are based on the following passage. New Stanford research reveals that farmers

Questions are based on the following passage.

New Stanford research reveals that farmers in Europe will see crop yields affected as global temperatures rise, but that adaptation can help slow the decline for some crops.

For corn, the anticipated loss is roughly 10 percent, the research shows.

Farmers of these crops have already seen yield growth slow down since 1980 as temperatures have risen, though other policy and economic factors have also played a role.

"The results clearly showed that modest amounts of climate change can have a big impact on yields of several crops in Europe," said Stanford doctoral student Frances Moore, who conducted the research with David Lobell, an associate professor of environmental Earth system science.

Moore described the results as somewhat surprising because Europe is fairly cool. "So you might think it would benefit from moderate amounts of warming,"she said. "Our next step was to actually measure the potential of European farmers to adapt to these impacts."

"By adaptation, we mean a range of options based on existing technologies,such as switching varieties of a crop, installing irrigation or growing a different crop, one better suited to wanner temperatures," said Lobell. "These things have been talked about for a long time, but the novelty (新奇) of this study was using past data to quantify (量化) the actual potential of adaptation to reduce climate change impacts. We find that in some cases adaptation could substantially reduce impacts, but in other cases the potential may be very limited with current technologies."

Moore pointed out that the biggest issues are often how quickly farmers in Europe will adapt to climate change (adaptation uncertainty) and how crop yields will respond to climate change (response uncertainty).

"This paper has shown that crops in Europe are sensitive to wanning and that adaptation can be important in reducing that impact," Moore said. "The next question is how quickly farmers will use the available options for adapting.

Europe has already seen a lot of warming, so we should expect to already see adaptation if farmers are quick to respond to climate signals,"

What does the new Stanford research show? 查看材料

A.People can do nothing about global wanning.

B.The influence of global temperature rise is increasing.

C.People can do something to slow the decline for some crops.

D.All crops" yields will decline as global temperatures rise.

听力原文:Experts say some farming activities are seriously damaging Earth's environment. B

听力原文: Experts say some farming activities are seriously damaging Earth's environment. Bad farming methods can damage soil, forests and water supplies. They also have caused some plants and animals to disappear.

Two groups now say that bad farming methods are threatening the ability of farmers to produce enough food to feed the world population in the future.

The groups used satellite images, maps and modern equipment to study the effect of agriculture on the environment. The study found that the destruction of soil is widespread. Important organic nutrients are being removed from farmland.

Agriculture uses seventy percent of the freshwater in the world each year. The study found that many farmers are wasting water supplies. In addition, chemicals designed to protect crops may pollute waterways.

The report also says as much as thirty percent of the world's forests have been cut down so the land could be used for agriculture. This has led to a severe loss of wildlife and their environments.

(30)

A.Soil.

B.Human population.

C.Forest.

D.Water.

听力原文:Scientists have observed that plants themselves produce many poisonous chemicals

听力原文: Scientists have observed that plants themselves produce many poisonous chemicals for defence against insects. But insects have developed ways of dealing with them and, in fact, have been eating plants for about 250 million years. Now insects are using these same mechanisms to deal with man-made poisons--insecticides. This is why resistance of insects to insecticides has developed so rapidly.

What should be done? Scientists studying the problem suggest that farmers use less insecticides. At the moment, farmers regularly spray crops as a precaution against problems that are caused by large numbers of pests. They should, instead, spray only where pests have actually been seen. Secondly, farmers could use a combination of two or three insecticides at once. To survive, the insects would need to become resistant to two or more poisons at the same time.

The most surprising suggestion, perhaps, is that, at certain times of the year, farmers should actually try to attract new insects onto the crops they are trying to protect. The new insects will mate with those which survived from a certain kind of insecticide and will lessen the latter's resistance to it.

Scientists hope that these and other measures will postpone the day when farmers and scientists will have to stand by while new super-bugs which may be resistant to all our poisons invade our farms and eat our crops.
