Uni t 2 A pi oneer for al l peopl e Al though he i s one of Chi na?s m ost fam ous sci enti sts, Yuan Longpi ng consi ders hi m sel f a farm er, for he works the l and to do hi s research. Indeed, hi s sunburnt face and arm s and hi s slim , strong body are just l i ke those of m il li ons of Chi nese farm ers, for whom he has struggl ed for the past fi ce decades. Dr Yuan Longpi ng grows what i s cal l ed super hybri d rice. In 1974, he becam e the first agri cultural pi oneer in the worl d to grow Ri ck that has a hi gh output. This speci al strai n of Ri ck m akes i t possi bl e to produce onethi rd m ore of the crop i n the sam e fi el ds. N ow m ore than 60% of the ri ce produced i n Chi na each year i s from thi s hybri d strain. Born i nto a poor farm er?s fam il y i n 1930, Dr Yuan graduated from Southwest Agri cul tural Col ege i n 1953. Si nce then, fi ndi ng ways to grow m ore ri ce has been hi s li fe goal. As a young man, he saw the great need for i ncresi ng the ri ce output. At that tim e, hunger was a di sturbi ng probl em i n m any parts of the countrysi de. Dr Yuan searched for a way to i ncrease ri ce harvests wi thout expandi ng the area of the fi el ds. In 1950, Chinese farm ers coul d produce onl y fi fty mi l i on tons of ri ce. In a recent harvest, however, nearl y two hundred m il i on tons of ri ce was produced. These i ncreased harvests m ean that 22% of thwart worl d?s peopl e are fed from just 7% of the farm l and i n Chi na. Dr Yuan i s now ci rcul ati ng hi s knowl edge i n India, Vi etnam and many other l es devel oped countri es to increase thei r ri ce harvests. Thanks to hi s research, farm ers are produci ng harvests twi ce as l arge as before. Dr Yuan i s qui te sati sfi ed wi th his l i fe. H owever, he doesn39。t care about bei ng fam ous. H e feels i t gi ves him l ess freedom to do hi s research. H e woul d rather keep ti m e for his hobbi es. H e enjoys l i steni ng to vol i n m usic, pl ayi ng m ahjong, swimm i ng and readi ng. Spendi ng m oney on hi msel f or l eadi ng a fortabl e l ife al so means very li ttl e to hi m. Indeed, he beli eves that a person with to m uch m oney has m ore rather than fewer troubl s. H e therefore gi ves m il li ons of Yuan to equi p others for thei r research i n agri cul ture. Just dreami ng for things, however, costs nothi ng. Long ago Dr Yuan had a dream about rice pl ants as tal l as shum. Each ear of ri ce was as bi g as an ear of corn and each grai n of ri ce was as huge as a peanut. Dr Yuan awoke from his dream wi th the hope of produci ng a ki nd of ri ce that coul d feed m ore peopl e. N ow, m any years l ater, Dr Yuan has another dream : to export his ri ce so that i t can be grown around the gl boe. O ne dream i s not al ways enough, especi al l y for a person who l oves and cares for hi s peopl e. Chem i cal or ani c farmi ng? O ver the past hal f century, using chemi cal fertil i zers has ve e very m on i n farmi ng. Many farm ers wel ed them as great way to stop crop di sease and i ncrease producti on. Recentl y, however, sci enti sts have ben fi ndi ng that l ongterm use of these fertil izers can cause dam age to the l and and, even m ore dangerous, to people?s heal th. What are som e of the probl ems caused by chem ical fertil i zers? Fi rst, they damage the l and by ki l i ng the hel pful bacteria and pests as wel l as the harmful ones. Chemi cal s al so stay i n the ground and underground water for a l onog tim e. Thi s affects crops and, therefore, anim al s and hum ans, si nce chemi cal s get i nsi de the crops and cannot just be washed off. These chem i cal s i n the food suppl y buil d up i n peopl e?s bodi es over tim e. Many of these chemi cal s can l ead to cancer or other il lnesses. In addi ti on, frui t, vegetabl es and other food grown wi th chemi cal ferti li zers usual ly grow too fast to be ful of m uch nutri ti on. They may l ook beauti ful , but i nsi de there i s usual y m ore water than vi tam i ns and m i neral s. With these di scoveri es, som e farmers and m any custom ers are begi nni ng to turn to ani c farm i ng. O rgani c farmi ng i s sim pl y farm i ng without using any chemi cal s. They focus on keeping thei r soi l rich and free of di sease. A heal thy soi l reduces di sease and That39。s why it?s cal l ed ?The Land of the Mi dnight Sun?. ” There were peopl e on the streets and snowm obil es everywhere. There were even a few dog team s. 必修四 Unit 1 A STUDEN T O F AFRICAN WILDLIFE It i s 5: 45 am and the sun i s just ri si ng over Gom be N ati onal park in east Africa.
