Dr Yuan awoke from his dream with the hope of producing a kind of rice (that could feed more people).e.g: He went to the U.S with the hope of finding a better job there.Step 6Closing down by having a dictationTo end the period you will take a d ictation. 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 famous scie ntist 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 paddy fields, but unlike those farmers, he reaps the seed from experimental fields only for hybridizing rice.。
