Reading Comprehension Learning aims: Get the students to know the achievements by reading the materials

Pre-class work: Read the background knowledge before reading the text. 1.

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 scientist (Yuan Longping and Jia Sixie). Agriculture, however, forms a large part of China’s economy and a large proportion of China’s population still works the land. It should be useful and interesting to examine 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.

2.

The Food and Agriculture Organization of the United Nations(FAO) The FAO leads international effects to defeat hunger. Serving both developed and developing countries, the FAO acts as a neutral forum where all nations meet as equals to the negotiate agreements and debate policy. The FAO is also a source of knowledge and information, in addition to helping developing countries and countries in transition modernize and improve agriculture, forestry and fisheries practices and ensure good nutrition for all. Since its founding in 1945, the FAO has focused special attention on developing rural areas, home to 70 percent of the world’s poor and hungry people. The FAO’s activities comprise four main areas:

Putting information within reach

Sharing policy expertise Providing a meeting place for nations

Bringing knowledge to the field
