Questin Time
Why des Yuan Lngping cnsider himself a farmer?2. What des Paragraph 1 tell us abut Yuan Lngping as a “pineer fr all peple” directly and indirectly ?
Because he cntinually wrks the land in his research.
Pssible answers: 1.Yuan is knwn as “father f hybrid rice”. Father means the first persn t d smething, r a pineer. 2. His methd f ding the pineering wrk is mainly field research. 3. Yuan has devted all his life t pineering agricultural research.
Yuan Lngping was brn in 1930 in Beijing. His parents wanted him t pursue a career in science r medicine.

T tackle this crisis, he chse t study agriculture and received an educatin at Suthwest Agricultural Cllege in Chngqing.
3. Why did Yuan decide t study agriculture?
What cncerned him mst was that farmers ften had pr harvests and smetimes even had a serius shrtage f fd t eat. T tackle this crisis, he chse t study agriculture.
After graduating in 1953, he wrked as a researcher. Yuan Lngping realised that larger fields were nt the slutin. Instead, farmers needed t bst yields in the fields they had. Hw this, culd be dne was a challenging questin at the time. Yuan was cnvinced that the answer culd be fund in the creatin f hybrid rice. A hybrid is a crss between tw r mre varieties f a species.
One characteristic f hybrids is that they usually attain a higher yield than cnventinal crps. Hwever, whether it was pssible t develp a hybrid f self-pllinating plants such as rice was a matter f great debate. The cmmn assumptin then was that it culd nt be dne. Thrugh intense effrt, Yuan vercame enrmus technical difficulties t develp the first hybrid rice that culd be used fr farming in 1974. This hybrid enabled farmers t expand their utput greatly.
4.What is the main advantage f hybrid crps?
This hybrid enabled farmers t expand their utput greatly.
5.The tw challenges that Yuan faced.
1） Hw t bst yields in the fields Slutin: the creatin f hybrid rice2）Whether it was pssible t develp a hybrid f self-pllinating plants. The cmmn assumptin then was that it culd nt be dne. Slutin: Thrugh intense effrt, Yuan vercame enrmus technical difficulties t develp the first hybrid rice.
Tday, it is estimated that abut 60 percent f dmestic rice cnsumptin in China is cmprised f crps generated frm Yuan’s hybrid strains, and his strains have allwed China’s farmers t prduce arund 200 millin tns f rice per year. Yuan’s innvatin has helped feed nt just China, but many ther cuntries that depend n rice as well, such as India and Vietnam. Because f his invaluable cntributins, Yuan Lngping has received numerus awards bth in China and abrad.
6. Hw has Yuan’s wrk helped China and ther cuntries?（pay attentin t the data）
It is estimated that abut 60 percent f dmestic rice cnsumptin in China is cmprised f crps generated frm Yuan’s hybrid strains, and his strains have allwed China’s farmers t prduce arund 200 millin tns f rice per year. Yuan’s innvatin has helped feed many ther cuntries that depend n rice as well, such as India and Vietnam.
Given that Yuan’s hybrids have made him quite wealthy, ne might think he wuld retire t a life f leisure. Hwever, this is far frm the case. Deep dwn, Yuan is still very much a farmer at heart. As a man f the sil, he cares little fr celebrity r mney. Instead, he makes large dnatins t supprt agricultural research.
What impresses peple mst abut Yuan Lngping is his nging ability t fulfill his dreams. Lng ag, he envisined rice plants as tall as srghum, with each ear f rice as big as a brm, and each grain f rice as huge as a peanut. He succeeded in prducing a kind f rice that culd feed mre peple at hme and abrad. His latest visin fr “seawater rice” has als becme a reality, and ptentially pened up nearly ne millin square kilmetres f salty land in China fr rice prductin. Despite his advanced years, Yuan Lngping is still yung at heart and full f visin, and everyne is waiting t see what he will dream up next.
7. What is Yuan’s latest visin? 8. Read Paragraphs 5 & 6 clsely t find ut what Yuan Lngping did after his great success.
