He has been working on agriculture education & the research into hybrid rice since he left the institute.In the 1960s, when China was suffering from serious famine, he came up with the idea of hybrid rice, which has a high yield ( or output). Ten years later, he succeeded in inventing a new species that produced a 20 percent higher yield than common types of rice.Yuan devoted himself to the research into agriculture, & was honored by UNESCO & FAO(联合国教科文组织）. Although he is 74 years old, he is still working on the research into agriculture.Period 2 ReadingStep 1 Lead-in。

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 scientist 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.Unit2 Working the landListening, Speaking and WritingLearning AimsTo help students read the passage Organic Farming.To help students to use the language by reading, listening, speaking and writing.ProceduresI．Warming up by listening and reading aloudLanguage is created to be listened to and spoken first.
