module4 unit 2 working the land全单元教案[下学期]

TEACHING PLAN FOR UNIT 2(Book 4)
Working the land
I. Brief statements Based on the Unit
This unit is concerned with introducing students to the study of agriculture. Growing food is connected with healthy food so part of the unit deals with “organic farming” or green food (food grown without chemical fertilizers). It is hoped that the students will become more aware of the quality of the food they are eating and buy more green food. The unit also introduces modern agricultural problems (desertification) and agricultural scientists (Yuan Longping and Jia Sixie). Agriculture, however, forms a large part of China’s population still work on the land. So it is useful and interesting to examining different aspects of agriculture so that students can see that a prosperous future can be made in agriculture. It is, also, important that everybody recognizes and values the agricultural contribution to China’s wealth and prosperity.
II. Teaching Goals
1. The students can talk about agriculture in their own way.
2. Practise making suggestions and advice.
3. The students are albe to use the V-ing form as the subject & object.
4. The students are able to write a poster.
5.

Playing tricks on others is something we should never do．
2)学习新单词对我来说非常重要。
Learning new words is very important for me．
3)说比做容易。
Talking is easier than doing.

Seeing is believing.
②用形式主语it，把真正的主语——动名词结构移置句尾。但这种句子形式有一定的限制，作表语的只能是某些形容词或少数名词，如useful，useless，good，fun；no use，worth等。如：
和夏洛克争辩是没有什么用的。
It is useless trying to argue with Shylock．
这事值得去做。
It’s worth making the effort．
想再解释一次有好处吗
Is it any good trying to explain
跟你在一起工作是令人愉快的。

⊙ 动名词与不定式做主语时的比较：
动名词表示的动作通常是一个泛指的动作，
不定式则通常表示具体的动作。如：

It is/was hardly/scarcely worth doing 做…不值得
There is no sense in doing 做…没有道理
There is/was no use doing 做…无意义
There is/was no point doing 做…无意义

注意：There is no need to do sth 做…没必要，在此句式中to do 不可换为doing.
没有必要告诉她。
There is no need to tell her.
⊙ 提示：当动名词用作主语时，其逻辑主语由形容词性物主代词和名词所有格构成。
我姐姐病了，使我很担心。
My sister's being ill made me worried.
你正确未必就意味着我错了。
Your being right doesn't necessarily mean my being wrong.
2、用作动词的宾语
动名词作宾语有两种情况。一是有些动词只能后接动名词作宾语；二是有些动词既可后接动名词也可后接不定式作宾语。

Period 4 Using language-----Organic farming
GOALS:
1. To learn what is organic food.
2. To express freely with the language the students have learned.
3. The students will become more aware of the quality of the food they are eating & buy more green food..
TEACHING PROCEDURES:
Step 1 First reading
Read the passage, then find out the topic sentence of each paragraph
Para 1: What is organic farming
Para 2: The fertilizer that organic farmers prefer is natural waste from animals.
Para 3: Organic farmers insist on changing crops every two or three years.
Step 2 Second reading
Read the text again and answer the following questions:
1. What is organic farming
2. What problems are caused by using chemical fertilizers
3. Why do organic farmers grow peas or soybeans after corn or wheat
Possible answers:
Organic farming means growing crops without chemical fertilizers.----green food
There are three problems.
Firstly, chemical fertilizers affect the soil and the water supply badly.
Secondly, they allow farmers to grow the same crop year after year and exhaust the soil.
Thirdly, they kill both helpful and harmful pests.
Farmers grow peas or soybeans after corn or wheat so that peas and beans can put minerals back into the soil, making it rich and healthy and ready to grow more wheat or corn.
Step 3 Third reading
Read the text again, and fill in the following forms.
Advantages of organic farming Reasons
1.Farmers use natural waste from animals. 1.This makes the soil richer in minerals and so more fertile.
2.The soil is not exhausted. 2.Peas and soybeans renew the minerals in the soil becomes rich and healthy.
3.They use the soil to best advantage. 3.They plant crops that need surface soil and next crops that grow at a deeper level. So the wind and water doesn’t carry away the soil. All the richness of the soil is used.
What are the disadvantages of using chemical fertilizers
1. Leaving chemicals in the ground for a long time is not good for the soil or the water supply.
2. Farmer often grow the same crop year after year. As a result, the soil gets exhausted.
3. Chemical fertilizers kill both helpful and harmful bacteria and pests.
Step 4 Retelling
Retell the text according to the chart: Organic farming
I. Organic farming…natural / chemical fertilizers
II. Farmers prefer natural waste from animals.
Natural fertilizer
1. make…richer and more fertile
2. reduce…and help…grow…
3. air, soil, water, food supply…free from chemicals
Chemical fertilizer
1. leaving…is not good
2. grow…year after year
3. kill … bacteria & pests
III. Farmers change crops every two or three years.
…to make sure what is left …
Step 5 Discussion
What is “Genetically Modified Food”
GM Food is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular(分子的) biology techniques. These plants have been modified in the laboratory to enhance desired traits(特点) such as increased resistance to herbicides(除草剂) or improved nutritional content.
Through GM it is possible to change fruits, vegetables & even animals. We can change the way they grow, where they can grow, how they will taste, what color & what shape they will have.
For example:
watermelon onion wheel
Discussion：Do you think it is good or not to eat GM Food
Benefits
Crops
Enhanced taste and quality
Reduced maturation(成熟) time
Increased nutrients, and stress tolerance(抗药力)
Improved resistance(抵抗) to disease, pests, and herbicides
New products and growing techniques
Animals
Increased resistance, productivity, hardiness, and feed efficiency
Better yields of meat, eggs, and milk
Improved animal health and diagnostic methods
Environment
