Unit 2 Working the landPart I a Pioneer for all PeopleAlthough he is one of China’s most famous scientists, Yuan Longping consider s himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggle d for the past five decade s. Dr Yuan Longping grows what is called super hybrid rice. In 1974, he became the first agricultural pioneer in the world to grow rice that has a high output. This special strain of rice makesit possible to produce one-third more of the crop in the same field s. Now more than 60% of the rice produced in China each year is from this hybrid strain.Born in 1930, Dr Yuan graduate d from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in many parts of the countryside. Dr Yuan search ed for a way to increase rice harvest s without expand ing the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produce d. These increased harvests mean that 22% of the world’s people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his research, the UN has more tool s in the battle to rid the world of hunger. Usinghis hybrid rice, farmers are producing harvests twice as large as before.Dr Yuan is quite satisfied with his life. However, he doesn’t care about being famous. He feel s it gives him less freedom to do his research. He would much rather keep time for his hobbies. He enjoy s listening to violin music, playing mah-jong, swimming and reading. Spend ing money on himself or lead ing a comfortable life also means very little to him. Indeed, he believe s that a person with too much money has more rather than fewer trouble s. He therefore gives millions of yuan to equip others for their research in agriculture.Just dream ing for things, however, cost s nothing. Long ago Dr yuan had a dream about riceplants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice wasas huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice thatcould feed more people. Now, many years later, Dr Yuan has another dream: to export his rice so that it can be grown around the globe. One dream is not always enough, especially for a person who loves and cares for his people.Part II Chemical or Organic Farming?Over the past half century, using chemical fertilizers has become very common in farming. Many farmers welcome d them as a great way to stop crop disease and increase production. Recently, however, scientists have been finding that long-term use of these fertilizers can cause damage to the land and, even more dangerous, to people’s health.What are some of the problems caused by chemical fertilizers? First, they damage the land by kill ing the helpful bacteria and pests as well as the harmful ones. Chemicals also stay in the ground and underground water for a long time. This affect s crops and, therefore, animals and humans, since chemicals get inside the crops and cannot just be wash ed off. These chemicals in the food supply build up in people’s bodies over time. Many of these chemicals can lead to cancer or other illnesses. In addition, fruit, vegetable s and other food grown with chemical fertilizers usually grow toofast to be full of much nutrition. They may look beautiful, but inside there is usually more water than vitamin s and mineral s.With these discover ies, some farmers and many customer s are beginning to turn to organic farming. Organic farming is simply farming without using any chemicals. They focus on keeping their soil rich and free of disease. A healthy soil reduce s disease and helps crops grow strong and healthy. Organic farmers, therefore, often prefer using natural waste from animals as fertilizer. They feel thatthis makes the soil in their fields richer in minerals and so more fertile. This also keeps the air, soil,water and crops free from chemicals.Organic farmers also use many other method s to keep the soil fertile. They often change thekind of crop in each field every few years, for example, growing corn or wheat and then the next yearpeas or soybeans. Crops such as peas or soybeans put important mineral s back into the soil, making it ready for crops such as wheat or corn that need rich and fertile soil. Organic farmers alsoplant crops to use different level s of soil, for example, planting peanuts that use the ground’s surface followed by vegetables that put down deep root s. Some organic farmers prefer planting grass between crops to prevent wind or water from carry ing away the soil, and then leaving it in the groundto become a natural fertilizer for the next year’s crop. These many different organic farming methodshave the same goal: to grow good food and avoid damaging the environment or people’s health.。

Book4 Unit2 Working the landA Pioneer For All People（Reading）一．教材分析：本单元的中心话题是农业，内容涉及到我国著名的杂交水稻专家袁农平先生的贡献、化肥对土地耕种的影响以及开展有机生态耕种等等。

本单元的语言知识点和语言技能都是紧紧围绕这一主题设计展开。

学生通过阅读和讨论，了解有关农业、农村和农作物种植的知识，了解农业在整个人类生活中的重要性，了解农村生活，了解农民生活的现状，提高对农业的认知。

本课主要介绍的是袁农平的生平和他的杂交水稻。

第一段主要介绍袁农平的外表形象，以及农村就是他的科研的殿堂，而其科研就是杂交水稻。

第二段描述袁的个人传记。

第三段介绍他过着和普通人一样的生活却从事着伟大的事业，成名后依然淡泊名利，有着无私奉献的精神。

第四段主要描述了袁隆平先生的梦想，表现出他为人民着想的优良品格。

二．学情分析：优点：高一年级学生，智力发展趋于成熟，渐渐形成用英语获取信息、处理信息、分析问题和解决问题的能力。

通过任务型课堂活动和学习，学生的学习自主性得到加强，主动参与到活动中去，成为课堂的主体，同时也加强了与他人交流合作的能力。

他们会对课文内容提出自己的疑惑和勇于阐述见解，并且从课内知识拓展到课外，通过多种渠道获取学习资源。

不过，学生的水平参差不齐，有些差距还相当大。

因此在教学过程中，布置的任务要兼顾各个层次的学生，争取做到因材施教。

缺点：学习的对象是处于城乡结合部农村的高一学生，他们的英语基础较差，特别是由于词汇量缺乏，阅读习惯不好，导致阅读速度慢、阅读理解能力差。

并且学生在初中已习惯了教师的单向灌输，部分学生由于英语表达能力的欠缺对课堂的互动缺少积极性，学习不够主动自主。

因此，在组织教学活动中，注重学习策略的指导，灌输自主、合作、探究学习的思想，同时注意调整活动任务设置的梯度，使每个学生通过学习活动，都能学有所成，体验到成功。

三．依据标准：本课主要依据新课程标准三维教学观，具体到英语学科就是要整合发展学生语言技能、语言知识、情感态度、学习策略和文化意识五个方面的素养，培养学生综合运用语言的能力。
