Teaching Procedures:Step 1: Lead in- Introduction Brainstorm: Question: What great scientists do you know? ( free speaking )Make students say something about those four great scientists- Qian Xuesen, Marie Curie, Archimedes, Albert Einstein.Name Nationality Major Invention/Discovery Time of the discoveryQian XuesenChina Physics, MathematicsChinese atom bombIn 1964Marie Curie Poland PhysicsRadioactivityIn 1898ArchimedesSicily in Italy Physics, mathematicsbuoyancyAbout 240 BCAlbert EinsteinGermany / AmericaMathematical PhysicsrelativityIn 1905Make students learn some words of different fields in science.SubjectsChinese meaning The person who research the subjectsBiochemistry生化学Biochemist Biology生物学Biologist Botany植物学BotanistChemistry化学ChemistGenetics遗传学GeneticistPhysics物理学PhysicistZoology动物学Zoologist Make students finish exercise 2 on page 31 individually.The answers:1. zoology 2. botany 3. biology 4. physics 5. biochemistry 6. chemistry 7. genetics Step 2: Reading and Vocabulary1. From the title “The Student Who Asked Questions”, guess what the passage is about?Who is the student?Question: What do you know about Yuan Longping?Name Nationality Major Invention/Discovery Time of the discoveryYuan LongpingChina Agriculture Hybrid rice In 19702. Make students find the topic sentence of each paragraph.Para1: Yuan Longping is a leading figure in the rice-growing world.Para2: As a boy, he was called “the student who asked questions”.Para3: As a young teacher, he began experiments in crop breeding.Para4: He discovered a special type of rice plant.Para5：His discoveries increased Chinese rice production.Para6：The yield of the new hybrid rice is much greater than that of other types grown in Pakistan.3. Make students skim the passage and find the answers to the following questions.1） What kind of student was Yuan Longping when he was young?2） What way did he think to produce rice more quickly?3） What did he discover?4） How important was the discovery？The possible answers：1） He was a student with lots of questions and he was interested in plants.2） By crossing different species of rice plant, then he could produce a new plant which could give a higher yield than either of the original plants.3） He discovered a naturally sterile male rice plant.4） Chinese rice production rose by 47.5% in the 1990s. There were other advantages.l 50,000 square kilometers of rice fields were converted to growing vegetables and other cash crops. l Yuans rice was exported to other countries.l His rices yield is much greater than the yield of other types of rice grown in Pakistan.4Make students read the passage carefully and decide whether the statement are true or false. 1). China produces more rice than any other country.2). Yuan Longping asked a lot of questions at school.3). He developed a new kind of fast-growing rice.4). The government helped him in his research.5). The new rice replaced vegetables in 50 thousand square kilometers.6). The new rice is now grown n other countries, such as Pakistan.The answers: TTTTFT5. Make students finish exercises in activity 3 and 4 on page 33 individually, then check the answers.Step 3: Language points1. He thought that (the key to feeding people was to have more rice and to produce it more quickly.) 宾语从句2. He though there was only one way to do this-by crossing different species of rice plant, and then he could produce a new plant which could give a higher yield than either of the original plants.3.First Yuan Longping experimented with different types of rice.experiment: (V.)做实验4. This was the breakthrough.5. 50 kilometres of rice fields were converted to growing vegetables and other cash crops.6. Following this, Yuan Longpings rice was exported to other countries, such as .Step 4: Function 1. Make a revisi
