Reference for TeachingBackground Information1.Crops1)CucumbersCucumbers are grown for eating fresh or preserving as pickles.They must be grown in warm temperatures and full sunlight,and will not stand frost.Cucumbers mature quickly and are best suited to large gardens but can be grown in small areas if caged or trellised.Cucumbers do best in loose,sandy loam soil but can be grown in any well drained soil.Remove rocks,large sticks and trash before preparing the soil.Leave fine pieces of plant material such as dead grass and small weeds.They will help enrich the soil when turned under.Spade the soil to a depth of 8 to 12 inches.This is about the depth reached by most shovels or spading forks.Turn each shovel of soil completely over so all plant materials are covered with soil.2)TomatoesTomatoes are warm season plants requiring at least six hours per day.Temperatures are very important.Most varieties of tomatoes will not set fruit unless the average nighttime temperature stays above 55 degrees.If nighttime temperatures are expected to drop below 55 degrees,protect the plants using a polyethylene film.One of the most common problems with tomatoes is called blossom end rot which appears as a gray or dark leathery scar or rot on the blossom end of the fruit.It is usually caused by sudden or inconsistent moisture levels in the soil.It can also be caused by a lack of calcium in the soil.Another common problem of tomatoes is blossom drop.This can occur if nighttime temperatures drop below 55 degrees and plants are not protected.Germination and tube growth are so slow that the blossoms drop off before they can be fertilized.3)PeasPeas are a frost-hardy,cool-season vegetable that can be grown throughout most of the United States,wherever a cool season of sufficient duration exists.For gardening purposes,peas may be classified as garden peas (English peas),snap peas and snow peas (sugar peas).Garden pea varieties have smooth or wrinkled seeds.The smooth-seeded varieties tend to have more starch than the wrinkled-seeded varieties.The wrinkled-seeded varieties are generally sweeter and usually preferred for home use.The smooth-seeded types are used more often to produce ripe seeds that are used like dry beans and to make split-pea soup.Snap peas have been developed from garden peas to have low-fiber pods that can be snapped and eaten along with the immature peas inside.Snow peas are meant to be harvested as flat,tender pods before the peas inside develop at all.The Southern pea (cowpea) is an entirely different warm-season vegetable that is planted and grown in the same manner as beans.2.Is Organic Food Safe?anic food is as safe to consume as any other kind of food.Just as with any kind ofproduce,consumers should wash before consuming to ensure maximum cleanliness.As cited above,organic produce contains significantly lower levels of pesticide residues than conventional produce.It is a common misconception that organic food could be at greater risk of E.coli contamination because of raw manure application although conventional farmers commonly apply tons of raw manure as well with no regulation anic standards set strict guidelines on manure use in organic farming:Either it must be first composted,or it must be applied at least 90 days before harvest,which allows ample time for microbial breakdown of any pathogens.Why does organic cost more?The cost of organic food is higher than that of conventional food because the organic price tag more closely reflects the true cost of growing the food:substituting labor and intensive management for chemicals,the health and environmental costs of which are borne by society.These costs include cleanup of polluted water and remediation of pesticide contamination.Prices for organic foods include costs of growing,harvesting,transportation and storage.In the case of processed foods,processing andpackaging costs are also anically produced foods must meet stricter regulations governing all these steps than conventional foods.The intensive management and labor used in organic production are frequently (though not always) more expensive than the chemicals routinely used on conventional farms.There is mounting evidence that if all the indirect costs of conventional food production were factored into the price of food,organic foods would cost the same,or,more likely,be cheaper than conventional food.3.International Coalition Proposes World Hunger ReformsRome,Italy,May 28 \—An international coalition promoting plant-based solutions to world hunger proposed sweeping reforms to delegates to the Food and Agriculture Organization meeting on world food security in Rome.The purpose of the meeting was to repair a flawed process that was supposed to reduce the number of chronically hungry people in the world by half by the year 2015.The coalition’s position paper makes several creative points to clear the impasse:A key root cause of world hunger,aside from natural disasters,pests,and wars,has been the insistence first by colonial powers and now by corporate interests on production of cash crops for export,in place of sufficient nutritious,safe,and accessible food for the local population.International trade can not solve world hunger because it shifts limited agricultural resources to production of cash crops for export,and people who don’t have access to food and other basic necessities of life have nothing to trade.Western meat industries,facing public awareness of the health impacts and strict environmental regulations at home,seek to exploit the natural resources,cheap labor,and potential markets of low-income food-deficient nations (LIFDNs).The definition of food security as the sustainable availability of sufficient amounts of nutritious,safe,and accessible foodstuffs leads inevitably to the choice of plant-based solutions and the avoidance of animal-based solutions.Affluent nations should act upon their moral obligation to provide the resources necessary to transport and distribute western food surpluses to the world’s hungry people and to help set up sustainable production of sufficient nutritious,safe,and accessible locally grown plant-based foods.They should reduce their own dependence on animal-based diets to release foodstuffs for the hungry.LIFDNs should scrutinize carefully all offers of resources to make sure that these truly meet their needs,rather than those of western corporate interests.They should insist on building up sustainable production of sufficient nutritious,safe,and accessible locally grown plant-based foods.In addition to distributing the position paper to the delegates,coalition activists also handed out leaflets at the FAO Rome headquarters.Additional actions are planned in connection with the World Food Summit to be held in Rome in November.Members of the coalition include FARM,a U.S.non-profit organization which has promoted sustainable,humane farming practices since 1976,and two Italian groups,Societa Vegetariana (Milan) and Progetto Vivere Vegan (Florence).4.Hunger:Vegetarian Solutions Now—VegfamVegfam is a charitable organization with the mission to feed the hungry without exploit in animals.It was founded in 1963 in England by Chris and Janet ter Ruth and Friedenstern Howard became Trustees.Frieden and others continue its work today out of the office in Devon,England.(VEGFAM,The Sanctuary,Nr Lydford,Okehampton,Devon EX20 4AL,England) For over 30 years,Vegfam has been working with and influencing major charities around the world,by co-financing projects that do not exploit animals.Vegfam works through indigenous on-the-spot representatives,and works with existing charities to support immediate and long-term food and water-aid projects.In working with existing charities,Vegfam educates these groups about the need for relief efforts that do not feed the hungry at the expense of animals and the environment.Short-term aid for famine victims includes purchasing grains,legumes,fruits,nuts,and vegetables,and providing water supplies.Long-term aid includes providing seeds for planting,irrigation projects,digging water wells,providing fruit and nut trees,providing vegetable plots and/or training people to grow vegetables,and Leaf Concentrate projects.Some of the countries aided by Vegfam are India,Bangladesh,Vietnam,Sudan,Ethiopia,Nigeria/Biafra,Somalia,Syria,Lebanon,Zimbabwe,and many more.In 1994 help was sent to Angola,Rwanda,and Bosnia.Donations made in 1995 were,in sterling;(1 = about $1.60),and the amounts are small compared to need,to:MALAWI (Monkey Bay) 1000 to finance running a Fruit Tree Nursery.The project is done in conjunction with Concern Universal and the Wildlife Society of Malawi.INDIA (Madurai) 1265 for two wells in Karumbalai for poor villagers who would otherwise have to walk afar.1935 to feed orphans in the orphanage at Chathirpatti.(The orphans are taken in from various disasters in India:flood,earthquake,plague,etc.) Both of these efforts are in support of the work of Pastor Jesudoss.INDIA (Jaipur) 500 for the leaf concentrate child feeding programs run by Find Your Feet.INDIA (Himalayas Kumaon) 500 for a medicinal and culinary herb nursery which will helpsubsistence farmers earn a living and overcome a food shortage,and preserve

population,Chinese farmers must produce enough food.On the other hand,they should produce more and better products which can be exported to improve their living standard.But China only has 7% of the land which can be used for farming.Therefore,farmers in China have always been looking for better methods and techniques to produce more food.They have also had to find ways to work on more land with fewer hands.In the past 20 years,great achievements have been made in China and China’s farming.With the help of new techniques and the outstanding work of scientists,China has not only solved the problem of hunger but also taken a lead in agricultural research,especially in super hybrid rice,crop genome,fertilizer and so on,causing products to multiply.It is a kind of agriculture although there are differences between land agriculture and water agriculture.Fish farming involves human help and produces fish protein crops rather than vegetable or meat protein crops.It has been used for 2000 years in China,Egypt and Rome.Fish can either be kept in earthen ponds or in cages with flowing water passing over the fish.If fish are kept in earthen ponds they can be fed either with extra natural food or with specially produced fish food.If fish are kept in cages they have to be fed on the specially produced fish food.When the fishare ready to be harvested and sold for eating,the earthen ponds can be emptied (if all the fish are to be harvested) or the water reduced (if some of the fish are to remain).In the cages all the fish would be harvested together.There is the problem of disease with fish kept in cages.They are generally too close together so they get lice.These parasites can be killed by giving medicine to the fish.But as time goes by,the medicine is not able to kill all the lice.So if some of the lice get onto the wild fish they kill many of them as wild fish have no medicine to protect them.So fish farming can cause problems for wild populations of fish.6.Modern AgricultureFor thousands of years traditional agriculture in China did not change very much.Most farms were one-family businesses.Although China is a very big country,only 7% of the land can be used for farming.It is on this arable land that the farmers produce food for the whole population of China.It is from the early 1990s that scientists started to develop new techniques to increase agricultural production without harming the environment.Chemical fertilization,for example,helps to produce better crops,but is harmful to the environment.New techniques should increase agricultural production but also be friendly to environment.Future agriculture should depend on high technology as well as traditional methods.Not only food production is important but also taking care of the environment.The biggest problem of Chinese farmers is the shortage of arable ing the latest technologies,Chinese scientists grow vegetables in greenhouses.The roots of these vegetables are not planted in earth but hang in water that contains all the nutrients they need to grow.Today,many vegetables are not grown in gardens but in greenhouses.They are protected from the wind,rain and insects.The temperature is controlled with computers,or kept the same,no matter how the weather is outside.Language points1.Dr Yuan grows what is called super hybrid rice.袁博士种植了被人称作超级杂交水稻的稻谷。

work.The students are asked to study three or four crops that are grown on the land,including where it grows;the varieties;its ideal environment.This activity is important for the students as it encourages independent learning and developsresearch skills.1.Assign each group to find out the information of one kind of crop.2.Students can search some information on the Internet,they can also gain a lot of information from a good set ofencyclopedia.3.Encourage them to do the work out of school as homework or independent project work.4.Help the students organize their information under the three headings:geography,varieties and environment.5.When students present their work,praise their efforts in class and give them encouragement and suggestions toimprove the quality of their future projects.6.Teacher can also display the students’ projects for other classes and their parents to see.Reference for TeachingBackground Information1.Crops1)CucumbersCucumbers are grown for eating fresh or preserving as pickles.They must be grown in warm temperatures and full sunlight,and will not stand frost.Cucumbers mature quickly and are best suited to large gardens but can begrown in small areas if caged or trellised.Cucumbers do best in loose,sandy loam soil but can be grown in any well drained soil.Remove rocks,large sticks and trash before preparing the soil.Leave fine pieces of plant material such as dead grass and small weeds.They will help enrich the soil when turned under.Spade the soil to a depth of 8 to 12 inches.This is about the depth reached by most shovels or spading forks.Turn each shovel of soil completely over so all plant materials arecovered with soil.2)TomatoesTomatoes are warm season plants requiring at least six hours per day.Temperatures are very important.Most varieties of tomatoes will not set fruit unless the average nighttime temperature stays above 55 degrees.Ifnighttime temperatures are expected to drop below 55 degrees,protect the plants using a polyethylene film.One of the most common problems with tomatoes is called blossom end rot which appears as a gray or dark leathery scar or rot on the blossom end of the fruit.It is usually caused by sudden or inconsistent moisture levels in the soil.It can also be caused by a lack of calcium in the soil.Another common problem of tomatoes is blossom drop.This can occur if nighttime temperatures drop below 55 degrees and plants are not protected.Germinationand tube growth are so slow that the blossoms drop off before they can be fertilized.3)PeasPeas are a frost-hardy,cool-season vegetable that can be grown throughout most of the United States,wherever a cool season of sufficient duration exists.For gardening purposes,peas may be classified as garden peas (English peas),snap peas and snow peas (sugar peas).Garden pea varieties have smooth or wrinkled seeds.The smooth-seeded varieties tend to have more starch than the wrinkled-seeded varieties.The wrinkled-seeded varieties are generally sweeter and usually preferred for home use.The smooth-seeded types are used more often to produce ripe seeds that are used like dry beans and to make split-pea sou p.Snap peas have been developed from garden peas to have low-fiber pods that can be snapped and eaten along with the immature peas inside.Snow peas are meant to be harvested as flat,tender pods before the peas inside develop at all.The Southern pea (cowpea) is an entirely different warm-season vegetable that is planted and grown in the samemanner as beans.2.Is Organic Food Safe?anic food is as safe to consume as any other kind of food.Just as with any kind of produce,consumers should wash before consuming to ensure maximum cleanliness.As cited above,organic produce contains significantly lower levels of pesticide residues than conventional produce.It is a common misconception that organic food could be at greater risk of E.coli contamination because of raw manure application although conventional farmers commonly apply tons of raw manure as well with no regulation anic standards set strict guidelines on manure use in organic farming:Either it must be first composted,or it must beapplied at least 90 days before harvest,which allows ample time for microbial breakdown of any pathogens.Why does organic cost more?The cost of organic food is higher than that of conventional food because the organic price tag more closely reflects the true cost of growing the food:substituting labor and intensive management for chemicals,the health and environmental costs of which are borne by society.These costs include cleanup of polluted water and remediation of pesticide contamination.Prices for organic foods include co sts of growing,harvesting,transportation and storage.In the case of processed foods,processing andpackaging costs are also anically produced foods must meet stricter regulations governing all these steps than conventional foods.The intensive management and labor used in organic production are frequently (though not always) more expensive than the chemicals routinely used on conventional farms.There is mounting evidence that if all the indirect costs of conventional food production were factored into the price of food,organicfoods would cost the same,or,more likely,be cheaper than conventional food.3.International Coalition Proposes World Hunger ReformsRome,Italy,May 28 \—An international coalition promoting plant-based solutions to world hunger proposed sweeping reforms to delegates to the Food and Agriculture Organization meeting on world food security in Rome.The purpose of the meeting was to repair a flawed process that was supposed to reduce the number of chronically hungry people in the world by half by the year 2015.The coalition’s position paper makes several creative points to clear the impasse:A key root cause of world hunger,aside from natural disasters,pests,and wars,has been the insistence first by colonial powers and now by corporate interests on production of cash crops for export,in place of sufficient nutritious,safe,and accessible food for the local population.International trade can not solve world hunger because it shifts limited agricultural resources to production of cash crops for export,and people who don’t have access to food and other basic necessities of life have nothing to trade.Western meat industries,facing public awareness of the health impacts and strict environmental regulations at home,seek to exploit the natural resources,cheap labor,and potential markets of low-income food-deficient nations (LIFDNs).The definition of food security as the sustainable availability of sufficient amounts of nutritious,safe,and accessible foodstuffs leads inevitably to the choice of plant-based solutions and the avoidance of animal-based solutions.Affluent nations should act upon their moral obligation to provide the resources necessary to transport and distribute western food surpluses to the world’s hungry people and to help set up sustainable production of sufficient nutritious,safe,and accessible locally grown plant-based foods.They should reduce their owndependence on animal-based diets to release foodstuffs for the hungry.LIFDNs should scrutinize carefully all offers of resources to make sure that these truly meet their needs,rather than those of western corporate interests.They should insist on building up sustainable production of sufficient nutritious,safe,and accessible loca lly grown plant-based foods.In addition to distributing the position paper to the delegates,coalition activists also handed out leaflets at the FAO Rome headquarters.Additional actions are planned in connection with the World Food Summit to be held inRome in November.Members of the coalition include FARM,a U.S.non-profit organization which has promoted sustainable,humane farming practices since 1976,and two Italian groups,Societa Vegetariana (Milan) and Progetto Vivere Vegan (Florence).4.Hunger:Vegetarian Solutions Now—VegfamVegfam is a charitable organization with the mission to feed the hung ry without exploit in animals.It was founded in 1963 in England by Chris and Janet ter Ruth and Friedenstern Howard became Trustees.Frieden and others continue its work today out of the office in Devon,England.(VEGFAM,The Sanctuary,Nr Lydford,Okehampton,Devon EX20 4AL,England)For over 30 years,Vegfam has been working with and influencing major charities around the world,by co-financing projects that do not exploit animals.Vegfam works through indigenous on-the-spot representatives,and works with existing charities to support immediate and long-term food and water-aid projects.In working with existing charities,Vegfam educates these groups about the need for relief efforts that do not feed the hungry at the expense of animals and the environment.Short-term aid for famine victims includes purchasing grains,legumes,fruits,nuts,and vegetables,and providing water supplies.Long-term aid includes providing seeds for planting,irrigation projects,digging water wells,providing fruit and nut trees,providing vegetable plots and/or training people to grow vegetables,and Leaf Concentrate projects.Some of the countries aided by Vegfam are India,Bangladesh,Vietnam,Sudan,Ethiopia,Nigeria/Biafra,Somalia,Syria,Lebanon,Zimbabwe,and many more.In 1994 help was sent to Angola,Rwanda,and Bosnia.Donations made in 1995 were,in sterling;(1 = about $1.60),and the amounts are small compared to need,to:MALAWI (Monkey Bay) 1000 to finance running a Fruit Tree Nursery.The project is done in conjunctionwith Concern Universal and the Wildlife Society of Malawi.INDIA (Madurai) 1265 for two wells in Karumbalai for poor villagers who would otherwise have to walk afar.1935 to feed orphans in the orphanage at Chathirpatti.(The orphans are taken in from various disasters in India:flood,earthquake,plague,etc.) Both of these efforts are in support of the work of Pastor Jesudoss.INDIA (Jaipur) 500 for the leaf concentrate child feeding programs run by Find Your Feet.INDIA (Himalayas Kumaon) 500 for a medicinal and culinary herb nursery which will help subsistence farmers earn a living and overcome a food shortage,and preserve the wild-growing herbs that are beingexcessively harvested.EL SALV ADOR 2500 for growing and drying cowpea leaves to add to children’s snacks to alleviatemalnutrition,in cooperation with a local agency,and Find Your Feet.So far in 1996 donations have been made to:INDIA,through Pastor Jesudoss:500 to help feed refugees from Sri Lanka,and 1220 to the orphanage.ZAMBIA:3000 for a maize grinding mill,donated through the Zambian Society Of Vegetarians.MEXICO:2000 for a dried leaf project of FIND YOUR FEET with cooperation of a local agency.NIGERIA,and awaiting funding,is a soy flour distribution project to be

Closing downClosing down by doing exercisesIn the last five minutes let’s do the comprehension exercises on page 10. Check your answers against your neighbour’s when you have finished.Closing down by having a dictationTo end the period you will take a dictation. It is about Yuan Longping, “Father of Super hybrid rice”.Yuan Longping, China's Most Famous "Farmer"Yuan came up with the idea of hybridizing rice for the first time in the world in 1960s.Since then, 50 percent of China's total rice cultivation fields have grown such rice,which added some 300 billion kilograms to the country's grain output. Furrows grown on his sunburnt face, a slim figure and coiled-up trousers legs would confuse foreign reporters who came to interview the most famousscientist in China, who would rather be called "a farmer." Indeed, like many Chinese farmers, Yuan in his 70s and has devoted most of his life growing rice in paddyfields,but unlike those farmers, he reaps the seed from experimental fields onlyfor hybridizing rice.。
