Unit 5
Working the Land
Using Language
Language Competence

Learning Ability
Enhance the skill of extracting and analyzing key information from texts about farming methods.
Cultural Awareness
Cultivate an understanding of the cultural significance and global perspectives of organic and chemical farming.
Thinking Quality
Promote critical thinking to evaluate the advantages and disadvantages of different farming approaches.
Learning Objectives
Teaching Focus
Master the key vocabulary and sentence patterns related to organic and chemical farming, and be able to use them in communication.
Teaching Challenges
Help students think critically and form a comprehensive understanding of the complex relationship between farming methods, environment and human health.
Teaching Focus and Teaching Challenges
Part 1
Listening
The first photo represents the idea of
drought. Either a river or a lake bed
has been exposed by receding waters,
leaving behind cracked soil. A child is
pouring water onto the ground. When
there is drought, crops cannot grow and animals may die.
Activity 1
In pairs, discuss what you can see in the photos and how you think each photo relates to world hunger.
①
The second photo represents the idea
of war.Hunger often comes with war,
as often people cannot farm, or they
cannot work to earn money to buy
food. And, even if they had money to
buy food, the markets might be empty or closed.
Activity 1
In pairs, discuss what you can see in the photos and how you think each photo relates to world hunger.
②
The third photo represents famine. The
child in the photo is a victim of famine,
which is why his/her arm and hand are
so thin. Famine is when the crops do not
grow and there is not enough food for everyone to eat. While famine can be caused by drought, some of the worst famines in world history had other sources, such as insects or diseases that destroyed the crops, or weather that was either too hot or too cool for the crops to grow properly.

Writing
Write an argumentative essay giving your opinion on chemical or organic farming.
Sample
In my opinion, organic farming is preferable to chemical farming because of the benefits to the environment and to people, and because organic food is more nutritious.
To begin with, chemical farming harms the environment. Since chemical pesticides are not found in nature, normal natural processes cannot get rid of them. Instead, the chemicals tend to accumulate in the soil and water, and are absorbed in the food chain, where they poison wildlife and domestic animals.

This affects us directly, because we end up eating plants, dairy products, eggs, and meat that have high levels of pesticides. Think about it: The purpose of the pesticides is to kill “pests”, that is, to kill insects. Something that can kill an insect probably is not healthy for a person to eat. While it may be true that the food we eat does not have enough pesticide in it to kill us immediately, over the years this pesticide may cause us health problems or give us diseases such as cancer.

Sample
Finally, organic food is generally more nutritious than food grown with man - made chemicals. If you remember a few years ago, there was the case of watermelons literally exploding in the fields because they had been given chemicals to make them grow faster. The reason why they exploded was that they contained too much water, because the farmers had used too many chemicals and the weather was unusually wet. As it turns out, such chemicals are commonly used in farming to grow larger crops more quickly. Do you really want to eat watered - down fruit and vegetables which have been rushed to market They cannot possibly taste as good as organic vegetables, nor can they be as nutritious.
In closing, I would like to suggest buying organic food. Yes, the price is a little higher, but the small price we pay extra will bring us huge rewards in the end.
