These chemi cal s i n the food suppl y bui ld up i n peopl e’s bodies over time. Many of these chemi cals can lead to cancer or other il nesses. In addition, frui t, vegetables and other food grown with chemical ferti lizers usual ly grow too fast to be ful of much nutrition. They may look beauti ful, but insi de there is usualy more water than vitamins and mi neral s. With these di scoveries, some farmers and many customers are beginning to turn to anic farmi ng.

There was story after story of how Lin Qiaozhi, tired after a day’s work,went late at night to deliver a baby for a pool family who coul d not pay her. By now I coul d not wait to find out m ore about her . I discovered that Li n Qi aozhi had devoted her whol e li fe to herpati ens and had chosen not to have a fami l y of her own. Instead she made sure that about 50, 000 babies were safel y deli vered.

She saw many por people li vi ng near her and she wanted to hel p them. O ne day she was asked to vi si t a pri son . At first the pri son offi cers di d not want to l et her visit the wom en prisoners because they feared the prisoners would attack her, but El i zabeth was not afraid. She reali zed that the pri soners behave badl ly because they were treated l ike anim al s. They had no beds,clean cl othes, food or heati ng. Any chil d born in pri son had to stay there and had no chance of an educati on. This m eant they woul d probably have to beg or steal when they grew up and then woul d return to pri son. So the fi rst thi ng Eli zabeth di d was to provi de food, cl ean clothes and straw for she began a prison school for the chil ldren and taught the wom en to sew, kni t and make gods to sel.

Unit 2 A pi oneer for al people Al though he i s one of Chi na’s m ost fam ous sci entists, Yuan Longpi ng consi ders himsel f a farmer, for he works the l and to do hi s research. Inded, hi s sunburnt face and arm s and his slim , strong body are just li 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 led super hybrid ri ce. In 1974, he becam e the fi rst agri cultural pi oneer i n the world to grow Ri ck that has a high output. Thi s special strai n of Ri ck m akes i t posible to produce onethi rd m ore of the crop in the same fiel ds. N ow m ore than 60% of the ri ce produced i n Chi na each year i s from thi s hybrid strain. Born i nto a por farmer’s fam il y in 1930, Dr Yuan graduated from Southwest Agri cul tural Col l ege in 1953. Since then, fi nding ways to grow m ore ri ce has been hi s l ife 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 sturbing problem i n m any parts of the countrysi de. Dr Yuan searched for a way to i ncrease ri ce harvests wi thout expanding the area of the fi el ds. In 1950, Chi nese farm ers coul d produce onl y fi fty mil li on tons of rice. In a recent harvest, however, nearly two hundred mil li on tons of rice was produced. These i ncreased harvests m ean that 22% of thwart worl d’s people are fed from just 7% of the farml and i n Chi na. Dr Yuan is now ci rculati ng hi s knowledge i n Indi a, Vietnam and m any other l ess developed countri es to i ncrease their ri ce harvests. Thanks to hi s research, farmers are produci ng harvests twi ce as l arge as before. Dr Yuan is quite satisfi ed wi th hi s li fe. H owever, he doesn39。t care about bei ng fam ous. H e fels i t gi ves him less freedom to do hi s research. He would rather kep ti me for hi s hobies. H e enjoy
