Step 1. Lead-in

1. What do you have for breakfast / lunch / supper?

2. What did your parents have in their childhood?

3. What are the differences between the foods you have now and your parents had in the past?

Step 2. Warming up

As you know, with the time passing by, people’s living standard is becoming higher and higher. As a result their eating habits have charged a lot. Now we are going to know some details about it by watching the graphs.

1. Teach the students how to read statistical graphs:

1) What is the graph about?

(Look at the words above or below the graph.

e.g. Growth of major farm products 1991-95 compared with 1986-90percentages)

2) See what is shown on the x-axis.

（the major farm products. Such as grain, cotton, oil, sugar, meat, fish and fruit)

3) See what is shown on the y-axis.

(the percentages of growth. 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%)

4) Which farm product grew most during the first five years of the 1990s?

(Fruit.)

5) How much did it grow compared with that during the last five years of the 1980s?

(90 percent)

6) Which farm product grew least?

(Grain.)

7) If three million pigs, sheep and cattle were raised during the years from 1986 to 1990, how many were raised from 1991 to 1995?

(4.9 million.)

Step3：Discuss:

1）How are people’s eating habits changing over the years?

Why do you think this happens?

Notes:

A. over the years: 在這幾年里

B. do you think: 插入語,經常位于疑問詞（組）后，有時也可以放在句尾。

e.g.1) Where do you think our English teacher comes from?

你認為我們英語教師來自哪里？

2)Who do you think the old lady is? 你認為那老太太是誰？

3)What is it, do you think? 你認為這是什么？

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

Note:

have an effect on: 對……產生影響

Step 4. speaking

Now let’s do speaking. This part says that a group of farmers in your area have been given a large piece of land. The villagers together with the village leader have to decide how to use the land. Work in groups of five students. Each group member will play one of the roles. Prepare role cards, discuss the problem and try to make a decision. Before discussion, who can give us some useful expressions about giving advice and making decisions?

Giving advice:

S1: My advice would be … . I advise you to do …

S2: I think you ought to …. You’d better ….

S3: If I were you, I would … I would advise you .

S4: I don’t think you ought to … .

Making a decision:

S1: In my opinion, we should … I think \ believe you should …

S2: I don’t think it is necessary to do sth. … . We must decide …

S3: I hope we can make a decision.

Now let’s have a discussion, using the expressions above.

Step 4. Post-reading

1. Finish the following passage according to what we learned today.

With the development of modern agriculture, farmers are realizing more and more the importance of protecting nature. Since the early 1990s, scientists have been trying to develop new techniques to increase agricultural production and protect the environment at the same time. Some chemicals can help to produce better crops but are very harmful to our environment. Some have a very good effect on removing weeds but they damage crops at the same time. So new techniques should not only help increase production but also be friendly to the environment. We should depend on high technology and traditional methods as well to develop our agriculture because food production and taking care of the environment are of the same importance.
