nto the ground，and lift up weeds，and other unwanted plants．However，plowing is blamed for causing severe damage to top soil by removing the plants that protect soil from being blown or washed away．Many farmers in South Asia are now trying a process called Low Till Farming．Low Till Farming limits the use of plows．In this method of farming，seeds and fertilizer are put into the soil through small cuts made in the surface of the ground．Low Till Agriculture leaves much or all the soil and remains of plants on the ground．They serve as a natural fertilizer and help support the roots of future crops．They take in rain and allow it to flow into the soil instead of running off．It has been proved that Low Till Farming increases harvests and reduces water use，and this method reduces the need for chemical products because there are fewer unwanted plants．Scientists say Low Till Fanning is becoming popular in South Asia，which is facing a severe water shortage．They say the area will become dependent on imported food unless water is saved through methods like Low Till Farming．Currently，more than 150 million people in South Asia depend on local rice and wheat crops．Farmers grow rice during wet weather．During the dry season they grow wheat in the same fields．Farmers are using the Low Till Farming method to plant wheat after harvesting rice．Scientists say Low Till Agriculture is one of the best examples in the world of technologies working for both people arid the environment．

听力原文：Prices continued to tumble across the board on local commodities today. The fall

in values has prompted a lot of anxiety in the farming community. The President of the Association of Cattle Farmers has warned that many farmers will face financial ruin if the prices do not recover. After three years of drought, farmers are at a breaking point. Farmers blame the fall in the value of their products on the government relaxing rules on primary commodity imports from developing countries, and a downturn in the economy as a whole. Farmers have warned that if this trend continues, the country will suffer in the long run.

听力原文： Experts say some fanning 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 70 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 30 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 discovered that plants themselves produce many poisonous chemical

听力原文： Scientists have discovered that plants themselves produce many poisonous chemicals for defense 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 insecticides at the same time.

The most surprising suggestion, perhaps, is that at certain times of the year, farmers should actually try to attract 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.

Scientist 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 poisons invade our farms and devour our crops.

What have scientists discovered about plants and insects？

A．Plants produce many poisonous chemicals for defense against insects.

B．Insects develop ways of dealing with natural poisonous chemicals but not man-made ones.

C．Farmers must spray plants all the time.

D．Farmers must use different brands of insecticides.

听力原文： The British government says it will decide within two days if it will start an animal treatment program to halt the spread of foot-and-mouth disease. Britain's National Farmers' Union has requested a quick decision.

Also in Moscow E. U. officials have protested Russia's ban on European meat imports. They say the 3-week ban is too strong because of measures the E. U. has now taken to control the disease.

听力原文：In many parts of the world, farmers and their families live in villages or towns.

听力原文： In many parts of the world, farmers and their families live in villages or towns. In the United States, however, each farm family lives on its own fields, often beyond the sight of any neighbors. Instead of traveling from a village to the fields every morning, American farmers stay on their land throughout the week. They travel to the nearest town on Saturdays for shopping or on Sundays for church. The children ride on buses to large schools which serve all of the farm families living in the area. In some areas, there are small schools serving a few farm families, and the children walk to school.

Of course life keeps changing for everyone, including farmers. Today there are cars, good roads, radios, and television sets. And of course there are modern machines for farming. All of these have changed farm life.

For many years, however, farming in America was often a lonely way of living. Farmers had to deal with their own problems, instead of getting help from others. They learned to try new methods, and to trust their own ideas instead of following older ways.

(30)

A．They live in bigger houses.

B．They live in villages or in towns.

C．Each family lives on its own fields.

D．They use modern machines in farming.

听力原文：Kenya was a beautiful country inhabited by different groups Of people, some farme

听力原文： Kenya was a beautiful country inhabited by different groups Of people, some farmers, some herds men, a few hunters, when the English arrived. The main motivations for. colonizing Kenya were economic—to take away resources; and strategic—to take control before the Germans or some other European "power" did. However, the English were a mixed group of people like everyone else. Manx English people were concerned about the welfare of Kenyans and worked under colonialism. These were civil servants, missionaries and some farmers, business and professional people who worked hard to develop Kenya both before and after independence.

Before Kenya was such a pleasant, easy place to live, another group of people came to live in Kenya, known generally as the settlers. The first settlers tended to be the social outcasts from wealthy families in England, though later they were joined by a wider group of English population. In particular, English soldiers who fought in the First World War were given farms in Kenya. This is a fantastic idea—to give a way land which does not belong to you in the first place. The people who actually owned the land tended either to be pushed off or to become servants and agricultural labors for the people who arrived from England.

(30)

A．English settlers.

B．Native farmers, herdsmen and hunters.

C．Missionaries, civil servants and professional people.

D．German settlers.

听力原文： European Commission President Jose Manvel Barroso and other top commissioners are heading to Washington D. C. to urge the Bush administration to make compromises that are necessary to successfully conclude the stalled Doha round of world trade talks.

It is not by chance that these top European diplomats are starting 2007 with a visit Monday to Washington D.C. They want a global trade agreement. They want it now and they believe the Bush administration is standing in the way. The five-year-long Doha round of world trade talks broke down last summer primarily over subsidies to American farmers which the U.S. refused to cut to levels agreeable to Europe. Private negotiating has nudged the issue forward. Peter Power, spokesman for Trade Commissioner Peter Mandelson, says the delegation will urge Mr. Bush to make the deal now.

European Commission President and other top commissioners are going to Washington to ask the American government to ______.

A．stick to their promises

听力原文：Some years ago I set up a small company to produce high quality food. I found org

anic farmers to supply all the ingredients, and used traditional recipes from around the world. We were producing small quantities so it was hard to keep prices competitive, but we managed it. My decision to sell through small, independent food stores was a mistake, though, because many of them were losing customers to the supermarkets, so sales were much lower than I expected.
