10、the previows we learnt some great women.Today well learn something about a famous man.At first lets look at the following pictures and tell me what the people are doing?Ss:They are farming.T:Are you from a farmers family?What do you know about farming?(Show the following chart word by word on the sc
11、reen,and ask them to tell more.)soilcropsploughingweather and climateirrigating.T:Maybe everyone knows something about the modern agriculture,but do you know anything about the agriculture in the past?Then show the students the following pictures:Agriculture in the pastThe modern agricultureStep 2 P
12、re-reading The purpose of this step is to let the students know the importance of rice.By answering the two questions,the students can easily understand why we call Dr Yuan Longping a pioneer for all people,and why he devotes all his life to the rice research.T:What is the main food in all East Asia
13、n and Southeast Asian countries?Ss:Rice.It is said that there are 2.4 billion people to eat rice every day throughout the world.T:What do you think would happen if there was suddenly no rice to eat?Ss:If that happened,people there would suffer from starvation.People would be panic(惊慌) and the whole
14、country would get into trouble.T:But today it will not happen because Dr Yuan Longping helps us.So today well learn a passage about Dr Yuan,the Father of hybrid rice.Lets come to the text.Step 3 Fast readingThe reading material is about an agricultural pioneer named Yuan Longping who worked hard at
15、a new strain of rice.It has proved so successful that his technology spread into other countries.The purpose of the fast reading is to let the students find some useful information，and get familiar with the text.So in this step,the teacher can design some questions the for the students,so that they
16、can easily find the answers and finish the reading task.T:Read the text fast and find out the answers to the questions on the screen.Then Id like to ask you to answer them.Show the questions on the screen and give the students three minutes to read the text quickly.1.What is Dr Yuans appearance?2.Wh
17、ats his achievement?3.Do you think he is a great man?Why?Three minutes later.T:Now who would like to answer the first question?S:1.He has a sunburnt face and arms and a slim,strong body.He is more like a farmer than a scientist.T:You are right,very good!What about the second one?S:2.He grows what is
18、 called super hybrid rice,which makes it possible to produce one-third more of the crop in the same fields.Thanks to his research,the UN is trying to rid the world of hunger.Using his hybrid rice farmers producing harvests twice as large as before.T:Do you think he is a great man?Why?(Ss give their
19、own answers.)Step 4 Detailed readingT:Please read the text again,and try to find the answers for the following questions: Ill give you four minutes.1.Why did Dr Yuan want to increase the rice output when he was young?2.How does he help rid the world of hunger?3.What kind of life is Dr Yuan leading?4
20、.Use a few words to describe Dr Yuans personality.Four minutes later.T:Who have found the answer for the first question?Suggested answers:1.Dr Yuan wanted to increase the rice output because he saw many people go hungry when he was young.2.He helps the world get rid of hunger by producing a hybrid s
21、train of rice which increase the harvest.3.Dr Yuan is leading a simple life,doing his research,listening to his music and riding his motor-bike.4.Dr Yuan is a simple,academic man who is more interested in helping others than being famous.Step 5 Extensive reading T:Now please read the text for the th

28、e 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 develops research skills.1.Assign each group to find out the information of one kind of crop.2.Students can search some information o
29、n the Internet,they can also gain a lot of information from a good set of encyclopedia.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 pre
30、sent their work,praise their efforts in class and give them encouragement and suggestions to improve 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)CucumbersCucumber
31、s 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
32、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 m
33、ost 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
34、 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 frui
35、t.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 grow
36、th 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
37、 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 us
38、ed 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
39、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?Yes.Organic food is as safe to consume as any other kind of food.Just as with any kind of produce,consumers should wash before c
40、onsuming 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 convent
41、ional farmers commonly apply tons of raw manure as well with no regulation whatsoever.Organic 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 an
42、y 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 bor
43、ne 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 and packaging costs are also included.Organically produced foods mu
44、st 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 c
45、osts 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 hu
46、nger 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 coalitio
47、ns 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,s
48、afe,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 dont have access to food and other basic necessities of life have nothing to trade.Western meat indus
49、tries,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
50、 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
51、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
52、 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 act
53、ivists 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，a
54、nd two Italian groups,Societa Vegetariana (Milan) and Progetto Vivere Vegan (Florence).4.Hunger:Vegetarian Solutions NowVegfamVegfam 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 Aldous.Later Ruth and
55、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 project
56、s 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 fee
57、d 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
58、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.Dona

64、Chinese AgricultureChina is a country whose population ranks the first in the world.In order to feed the whole 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
65、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 Chinas far
66、ming.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 althou
67、gh 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 flowi
68、ng 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 fish are ready to be harvested and sold for eating,the earth
69、en 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
70、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 A
71、gricultureFor 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.
72、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 b
73、ut 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 land.Using the latest technologies,Chin
74、ese 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
75、 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。what=the thing(s) thatThis special strain of rice makes it possible to produce one-third more of the crop in the same fields.这种特殊的稻种
76、使得同样的田地多收获三分之一的产量。it 在句中作形式宾语,真正的宾语为to produce.,结构为:动词（make,feel,think,regard.）+it +adj.+ to do。e.g.We think it important to learn English well.2.Since then,he has devoted his life to finding ways to grow more and more rice.从那以后,他就把毕生精力投入到水稻高产的研究中。devote oneself to+n./doing 献身于,致力于注意:to 为介词,后面接v.-in
77、g。类似的短语还有look forward to,listen to,get to,reply to,apologize to,belong to,agree to等等。3.Dr Yuan searched for a way to increase rice harvest without expanding the area of fields.袁博士寻求一种在不扩大种植面积的情况下提高水稻产量的方法。注意:search强调搜查,一般表示目标明确范围较小。search sb.搜身;search some place 搜查某地search for 强调寻找,一般表示范围较大。search f
78、or sb.寻找某人e.g.The police searched the woods for the lost child.警察在树林里寻找失踪的小孩。Scientists are still searching for a cure to the common cold.科学家们仍然在寻找普通感冒的治疗方法。4.Thanks to his research,the UN is trying to rid the world of hunger.由于他的研究,联合国正在努力清除世界饥饿。thanks to=because of;owing to e.g.Thanks to your supp
79、ort,we won the game.由于你的支持,我们赢得了比赛。5.Using his hybrid rice farmers are producing harvests twice as large as before.用他的杂交水稻种子,农民们种出比以前多一倍的粮食。倍数词（twice/half/three times/a quarter,etc.）+as + 形容词原级 +as.表示“是的多少倍”。e.g.The number of the students in our school is twice as large as that in their school.我们学校学
80、生的数量是他们学校的两倍。6.However,he cares little about spending the money on himself or leading a comfortable life.但是他很少想到要把钱花在自己的身上,或享受舒适的生活。lead a.life 过生活。英语中少数动词,包括一些不及物动词的宾语可能是与它同源的名词类似的短语动词有:die a.death,smile a.smile,dream a.dream,live a.life,sigh a.sigh,etc.。care (little/much) about:be concerned about“
81、关心,介意”,后面跟从句时,about常省略。care for:look after 照料;like or want 想要,喜欢e.g.Albert Einstein didnt care much about what to wear.Would you help to care for my pet while I am away?7.Dr Yuan is more a farmer than a scientist.与其说袁博士是一个科学家不如说他是一个农民。be more than=not only 不仅仅,超过e.g.Learning is more than reading.be more +A +than +B与其说是B还倒不如说是Ae.g.He is more an ordinary person than a leader.
