We shall read about man who works the land today. Have you ever grown any plants? If not, what kind of plant would you like to grow? How will you grow it?(For reference: Mr. Li, I worked with my father in the rice field last year. We grow hybrid rice and use animal wastes to make the soil rich.)Has anyone of you ever been to the countryside? What did you do there?(For reference: I went to Chuankou the day before yesterday.

Would anyone of you tell the class something about him?(For reference: Professor Y uan Longping is a Chinese agricultural scientist. 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.

As for the learning methods, they are poor in cooperative learning skills. Some students are not active in the class .Therefore , I ’ll have students study in a relaxed atmosphere.According to the analysis of the teaching material and the students’ learning background , I will use the following methods .Teaching Methods:In my opinion, the main instructional aims of learning English in the Middle School is to develop the students’ abilities of listening, speaking, re ading, writing and their good sense of the English language. So in this lesson I’ll mainly use “Communicative” Approac h,“Situational teaching”and “Task-based” language teaching .

(2)能力目标：让学生进一步使用恰当地阅读方式与技能，如略读(skimming)，快速阅读(fast reading)，细读(close reading)等(3)情感目标：让学生不但学习袁隆平的科研精神，更要学习他不计较名利，踏踏实实的生活态度。
教学重难点1.阅读课文更多地了解我国著名的农业科学家袁隆平的科研成果及其影响。
教学过程1. 话题的引导。
(Pre-reading)1).开头通过设计了一首熟悉的诗歌，让学生知道话题---farming.2).涉及到提高产量从而解决世界饥荒问题，从而引出本节课的中心话题--伟大人物袁隆平。
2. 跟读与限时阅读完成导学案练习贯彻目的与困难策略，指导学生根据不同的阅读目的，在阅读的不同阶段，灵活使用各种阅读策略，捕捉文章主要信息，理解作者的写作意图，突破本文的教学重点与难点。
采用整体语言教学法和任务型语言教学法。
1)、通过限时阅读训练，引导学生如何利用略读(skimming)的方法把握文章的大意，侧重培养快速阅读理解能力和文章中心把握能力。
2)、精读各个段落语段，侧重培养快速捕捉文章重要细节的能力和猜测生词的能力，学会欣赏文章中的优美句子。

人教版必修四Unit 2(Reading：A Pioneer For All People)教案(1)
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。

必修4Unit2教案：阅读策略指导
必修4 Unit 2教案：阅读策略指导英语阅读是学习英语的重要组成部分，而阅读能力的提高又需要阅读策略的指导。
Unit 2的教学内容涵盖许多丰富的阅读材料，不仅可以帮助学生丰富知识，提高英语水平，还可以帮助学生学习和理解不同类型文本的阅读策略，从而提高自己的阅读能力。
本文将从教师和学生两方面探讨必修4 Unit 2教案的阅读策略指导。
一、教师角度作为学生的引领者，英语教师要善于运用各种阅读策略指导学生进行英语阅读，培养学生的阅读能力。
在Unit 2的教学中，教师应关注以下几个方面：1.了解不同类型阅读材料的阅读策略在Unit 2的教学中，有包括新闻报道、科技文章、历史文章、文学作品等多种类型的阅读材料。
教师需要了解并熟悉不同类型阅读材料的特点，从而针对性地指导学生选择和运用不同的阅读策略。
2.深入分析文章，传授阅读技巧教师在引导学生进行阅读时，可以有意识地帮助学生深入分析文章，全面了解其中的内容和结构，并传授相关的阅读技巧，如预测、扫读、略读、细读等，让学生在阅读过程中更加得心应手。
3.培养不同阅读策略的组合使用英语阅读策略的运用并不是孤立的，教师需要引导学生掌握并合理运用不同的阅读策略。
例如，学生在进行细读时，可以结合预测和扫读等技巧，更好地把握文章的重点。
二、学生角度英语阅读能力的提高关键在于阅读策略的运用，因此学生需要认真学习和掌握各种阅读策略，课堂时间内的指导是为学生后续的阅读打下基础。
学生在进行英语阅读时，可以从以下几个方面入手：1.明确阅读目的，合理安排时间在进行阅读时，学生首先需要明确阅读目的，从而合理安排时间。
如果目的是快速浏览整篇文章，那么可以运用扫读技巧；如果目的是查找某一特定信息，那么可以运用略读技巧；如果目的是全面理解和掌握文章，那么可以进行细读。
2.发现关键词和主旨句在阅读文章时，学生需要及时发现关键词和主旨句，并根据关键词和主旨句来理解文章中的内容。
这样能帮助学生更好地理解文本，把握文章的核心内容。
