Unit 19 Modern Agriculture(人教版高一英語下冊教案教學設計)

單元標題解讀

本單元圍繞“modern agriculture” 這一主題展開聽、説、讀、寫等一系列教學活動。農業是人類生存和發展的基礎，農業的發展也是人類文明發展的一大體現。教材涉及到農業技術的發展和進步，發展和環境問題的矛盾，現代生態農業以及農作物培植的基因工程,中國古代的農業著作等多方面的內容，有着比較強的可挖掘性；同時，在學習本單元的過程中，可以促進英語學科與其他學科之間的相互滲透與聯繫，使學生的思維能力、想象力、協作和創新能力等綜合素質得到發展,同時培育學生的科技人文精神。

熱身（warming up）

以數據統計圖的形式導入本單元的話題。膳食結構的變化引起農業生產的變化---農業產業結構和比例的調整，從而引起生態和自然環境的變化。

聽力（listening）

本部分是一篇短文，從正反兩方面論述了農業生產與自然環境的關係，體現出人在從事農業生產的過程中的對自然環境的影響和作用。在設計上採用了聽選有關信息、判斷正誤和填充的形式，注重訓練對有效信息的捕捉和處理的能力。

讀(reading)

讀前(pre-reading)

結合幾幅極具代表意義的照片設計了兩個問題，激活學生已有知識和經驗，誘發學生觀察、思考、比較傳統農業和現代農業，現代農業的利與弊討論等，使學生進一步熟悉本單元的主要話題，為“讀”作好充分的準備；

閲讀中(while-reading)

“讀”部分以時間的先後為序簡要介紹了農業發展的歷程，側重介紹了現代農業的發展和新的成就，其中滲透着人在農業發展中和的作用和影響, 激活學生的科技人文意識。

讀後(post-reading）

本部分設計了三種練習，第一題以選擇題的形式檢測學生對課文的淺層次理解；第二題以問答題的形式檢查學生對文章一些句子的深層次理解；第三題是一個開放性的題目，鼓勵學生結合想象和其他學科知識，做出決定並解釋原因。通過這一任務的完成，不僅切實鍛鍊和提高學生的語言運用能力，而且加強了學科間的滲透，提高了學生的思維能力和創新能力。

説(speaking)

通過開村民大會的方式，使學生進入到十分接近真實生活的活動之中，模擬各種實際生活中的角色，暢所欲言，甚至激烈辯論，從各自的立場去尋求解決的途徑。這種活動促使學生進一步鞏固所學語言知識，活化所學語言技能，達到真實交流的目的。

語言學習 (language study)

包括兩個部分，詞彙部分設計了幾組通過後綴的添加而互相轉化詞性的練習，旨在培養學生對構詞法的意識，瞭解構詞規律；語法部分是有關強調句型的示例和練習，從易到難，有利於學生的掌握和實際運用。

綜合能力(integrating skills)

本部分是一篇介紹中國古代的農學家賈思勰和他的著作《齊民要術》的文章，主要涉及了他對農作物的種植的一些指導和看法，直到今天對農業生產都是適用的。文後的讀寫訓練中，首先，要學生根據需要完成對信息捕捉和加工的任務；第二個是開放性的任務，要學生為自己的菜園做種植計劃。這一任務的設計給學生充分的空間去創造性的運用所學知識，發展語言綜合運用的能力，從而達到了在做中學的目的。

小建議(tips)

給出了一些與農時、天氣有關的諺語，學生通過對這些諺語的理解和思考，並同中國的類似諺語比較，增強了學習的趣味性，也使他們的文化意識得到的潛移默化的培養和影響。

課時安排

Period 1 warming up & listening

Period 2 reading

Period 3 speaking

Period 4 grammar & integrating skills 2(WB)

Period 5 integrating skills 1 & writing(SB)

Period 1 warming up & listening

Task:

The students are to read the statistic graph & discuss the changes that the graph shows.

Goals:

1) To cultivate the students’ ability to read & analyze the graph.

2) To cultivate the students’ ability of listening for information.

Teaching procedure

Task 1 Brainstorming

What will you think of when you see the word “agriculture”? Ask the Ss to give as many words about agriculture as possible.

Task 2: Discussion

Ask the Ss: “How many meals do you have every day? Which meal do you think is the most important? Why?”

Now let’s have a discussion. (Divide the whole class into 2 groups.)

1 Group 1 & 2: What kind of food did we eat at breakfast, lunch & supper in the past? Group 3 & 4: What kind of food do we eat at breakfast, lunch & supper at present time?

breakfast lunch supper

In the past Porridge & salted

vegetables Noodles Rice & delicious dishes

At present Milk, bread, fried

bread, etc. Fast food Fast food

2 Why do you think people always prefer fast food? (fast; busy) What can we learn from the differences between the food in the past & at present time? (Now people live a better life; people are busier than before, etc.)

Task 3: Now open your books. Look at the graph on page 43 & answer the following questions.

Compared with the farm products from 1986-1990, we produced more grains, cottons … than before.

Why do we produce more farm products than before? (we live a better life; make more money; can afford more expensive food than before )

1 How are people’s eating habits changing over the years? Why do you think this happens?

2 How has agricultural product changed during these years? What do you think caused these changes?

3 What effects do you think the changes in eating habits will have on agriculture or nature?

Task 4: Listening

Pre listening

Ask the Ss: “What does agriculture depend on?” The Ss will give many different answers. After that, show the answer & the pictures on the screen.

(weather, places, water & other natural sources)

Question: If we changed the structure of agriculture, what do you think will happen to the nature?(We will produce less or maybe we can’t get any food at all.)

2) While listening

1 Listen to the tape. The passage you hear talks about

( T ) history of farming ( ) farmers in America ( ) fishing

( T ) protection of nature ( T ) farmers in China ( ) pigs

( T ) environmental problems ( T ) trees ( T ) dikes

2 Which of the following sentences are true & which are false?

1) In early times farmers in China moved around & burnt forests. ( T )

2) All farmers in South America burn forests to create farmland. ( F )

3) Flood & droughts are disasters that farmers cannot stop. ( F )

4) Some of the land in China is too wet to grow crops. ( T )

5) Fish farmers damage nature. ( F )

3 Listen to the tape & complete the sentences by using your own words.

When farming goes against nature, all kinds of environmental problems are the result. The earliest farmers destroyed nature. Their way of agriculture led to floods & droughts. It is an old truth that farming should not go against nature. The land that Tan & Xiao Zao bought was too wet & could not be used for farming. Instead they changed the fields into fishponds. On their farm they kept fish/ducks/chickens & grew fruit trees.

3) Post listening

Suppose you are Tan & Xiao Zao. Because of your successful farming on the field, you are invited to a big meeting that many local farmers will attend. You are asked to give a lecture about your experience telling how you have worked on the nearly deserted field & become a successful farmer.

5 Writing

袁隆平人物簡歷

袁隆平被譽為中國的“雜交水稻之父”. 中國農民説，吃飯靠“兩平”，一靠鄧小平----制定了生產承包責任制的政策，二靠袁隆平----發明了雜交水稻。

袁隆平，男，１９３０年９月出生於北京，１９５３年畢業於西南農學院農學系。畢業後，一直從事農業教育及雜交水稻研究。

在中國人民正鬧饑荒的20世紀60年代，袁隆平提出了雜交水稻的概念，這種新型水稻具有高產量的特點。10年後，他研製成功了一種產量比一般水稻高出20%的新型水稻。

袁隆平一生獻身於農業研究，先後受到聯合國教科文組織、糧農組織的稱譽。袁隆平雖已年屆70歲，仍然一如既往地從事農業研究。

New words: 雜交水稻hybrid rice; 生產承包責任制System of Production Responsibility; 學院institute; 鬧饑荒suffer the famine; 產量yield; 聯合國教科文組織UNESCO,糧農組織 FAO.

Possible version:

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 serious famine, he came up with the idea of hybrid rice, which has a high yield. 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. Although he is 70 years old, he is still working on the research into agriculture.

Homework:

Write a passage introducing Yuan Longping.
