II. Discuss the following questions in the text book.
1. How are people’s eating habits changing over the years?
The most significant changes are from a diet mainly based on rice and vegetables to a diet that still includes rice, with a greater variety in vegetables and a considerable quantity of meat.
Why do you think this happens?
(1). People are earning more money, so they want to buy and eat more meat.
(2). People learn more about healthy food, so they want to eat more fruit.
(3). Fruit juices are healthier than soft drinks such as cola, so people want to drink more juices.
(4). Fish is good to health, and it is said that it can make people become clever. And eating fish won’t make people fat.
(5). In order to taste good, people like to fry food. And it needs more oil.
2. How has agricultural produce changed during these years?
China now produces almost 80% more fish and fruit than twenty years ago. The produce of meat over the same period has increased by 60%. Oil and sugar are up about 30% each. Grain and cotton are up 10 and 15% respectively.
What do you think caused these changes?
(1). People want to buy different produces, so farmers need to grow different things.
(2). Farmers can make more money by growing fruits or fish farming than growing grain.
3. What effects do you think the changes in eating habits will have on agriculture or nature?
It may have both good and bad effects on nature.
(1). First, Chinese people are eating more meat. Next, farmers have to raise more pigs, sheep and cattle. So, more grass is needed to feed more sheep and cattle. So, farmers need more grassland. Then, people may cut down trees to take more land on which to grow grass.
(2). They also may destroy nature to get more land to grow grain and grass to feed animals.
(3). If farmers want to grow different crops, they would plant them together. This can be very good for the soil.
(4). Farmers can make full use of land to grow fruits in the places where other crops can’t be planted.
