Professor Yuan's breakthrough scientific achievement led to the world's first successful and widely grown hybrid rice varieties, revolutionizing rice cultivation in China and tripling production over a generation. His approach to rice breeding then spread internationally throughout Asia and to Africa and the Americas, providing food for tens of millions and leading to his becoming known as the "Father of Hybrid Rice."Step 4. ReadingReading aloud to the recordingComprehension—understanding what you are reading—is important. To read in thought groups is an easy, yet effective, way of improving reading comprehension. Now turn to page 9 and read aloud to the recording of the text A PIONEER FOR ALL PEOPLE. Pay attention to the thought groups in the sentences while listening and reading aloud.A brief introduction:Yuan Longping is known as China’s “father of hybrid rice”. It’s said that in China, we eat depending on “Two Ping” ---- Deng Xiaoping, who made the policy of System of Production Responsibility, & Yuan Longping, who invented hybrid rice.Yuan Longping, who was born in September, 1930, graduated from Agriculture Department in Southwest Agricultural Institute. 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.. Listen to the tape carefully then answer these questions.1)When and who did become the first agricultural pioneer in the world to grow rice that has a high output?2)What did Yuan Longping invent?Step2. Read the passage once again,then find out these sentences true or false.1)Dr Yuan is more a farmer than a scientist.2 )Dr Yuan’s kind of rice is the most suitable for China’s farmland.3)Dr Yuan would rather work than relax.4 )Dr Yuan has dreams when he is asleep and also when he is awake.5 )Dr Yuan enjoys a simpler life than most rich and famous people.Step3. Find out the topic sentences of each paragraphPara. 1: He became the first agricultural pioneer in the world to grow rice that has a high output.Para.2:He has devoted his life to finding ways to grow more and more rice..Para.3:He cares little about spending the money on himself and would rather keep time for his hobbies.Para.4 Dr. Yuan’s dreams.Step4. Write down Yuan Longping’s personal informationIn pairs, read the text, find information to complete the following form.Step 5 Language points:1. Struggle for…为争取……而斗争Struggle against…为反对……而斗争Struggle with… 与……争斗1)The swimmer struggled against the tide.2)We had to struggle with/against all kinds of difficulties.3)The slaves struggled for the freedom2. 使做…成为… make +it +adj./n. +to do好天气使游泳成为可能The fine weather makes it possible( for us )to swim.他将每早跑步做为一个规则He makes it a rule to run every morning.其他可用这种结构的词:feel, find, think, consider…3.搜查,搜索search (sb. / sth.) for …He searched all the rooms for the missing person.They searched the man all over for money.4.由于,多亏thanks to 相当于because of5.是从前两倍那么多twice as large as before相当于once larger than before6.对……感到满意be satisfied with…相当于be pleased withadj. satisfactory/satisfyingn. satisfaction7.在乎,在意care about比较care forMy aunt cared for me when my parents were away last week.Dr Yuan never cares about money and fame.8. Indeed, his sunburn face and arms and his slim, strong body are like those of millions of other Chinese farmers.e.g: The streets in Beijing are wider than those in my hometown.The number of students in our school is larger than that in their school.9. Dr Yuan grows what is called super hybrid rice.e.g: He came to what is called America.10. This special strain of rice makes it possible to produce one -third more of the crop in the same fields.e.g: That made it possible for life to begin to develop.The development of science makes it possible for us to know more about the universe.11. 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 peri od you will take a dictation. 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 themost 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.
