听力原文： Good morning and welcome to American studies 101. I would like to begin this semester by discussing the region of the United States known as the Northeast. This region includes twelve states and a small area called the District of Columbia that is the home of the national government.
The Northeast is a very important part of the United States, for although it covers only about six percent of the nation's geographical area, it contains approximately one-fourth of the country's population. New York, the most popular city in the United States, and several other large cities are located in this region.
Why are these twelve states so important？ In the first place, the Northeast was one of the first sections of the country to be settled by Europeans. Busy cities developed there when most of America was still a sparsely settled wilderness. Many crucial events in the nation's early history took place there. I'll be describing some of those events Wednesday in my second lecture.
Today the Northeast is a great manufacturing and trading region. Thousands of factories produce a wide variety of goods and provide other regions of the country with items they need. Many large manufacturing firms have their central headquarters here. Some of the country's largest banks, investment agencies, and publishing houses are found in the Northeast. Several of its cities are noted for their fine museums. Some of the country's best known colleges and universities are also located in this region.
Finally the Northeast is the principal location for much of the country's international trade. In the heart of this region New York city is the home of the United Nations.
(33)
A．On the first day of class.
B．At the end of the first week of classes.
C．Halfway through the semester.
D．Just before the final examination.

Organic Food
Organic farming was among the fastest growing segments of U.S. agriculture during the 1990s. The value of retail. sales of organic food was estimated to be $16 billion in 2004. According to the Food Marketing Institute, more than half of Americans now buy organic food at least once a month. Why is organic food becoming so popular？
What is Organic Food？
In December 2000, the National Organic Standards Board of the U.S. Department of Agriculture (USDA) established a national standard for the term "organic". Organic food, defined by how it cannot be made rather than how it can be made, must be produced without the use of sewer-sludge fertilizers, most synthetic fertilizers and pesticides, genetic engineering (biotechnology), growth hormones, irradiation and antibiotics. A variety of agricultural products can be produced organically, including produce, grains, meat, dairy, eggs, and processed food products.
"Organic" does not mean "natural". There is no legal definition as to what constitutes a "natural" food. However, the food industry uses the term "natural" to indicate that a food has been minimally processed and is preservative-free. Natural foods can include organic foods, but not all natural foods are organic. Only foods labeled "organic" have been certified as meeting USDA organic standards.
Organic Farming
The phrase 'organic farming' — first appeared in Lord Northbourne's book Look to the Land, published in 1940. But the truth is, organic farming is the oldest form. of agriculture. Before the end of World War Ⅱ, farming without the use of petroleum-based chemicals (synthetic fertilizers and pesticides) was the only option for farmers. Technologies developed during the war were found to be useful for agricultural production. For example, the chemical ammonium nitrate (硝酸铵), which was used as munitions (军需品), became useful as fertilizer, and organophosphates (有机磷酸盐) used for nerve gas were later used as insecticide.
These days, farmers are switching to organic agriculture once again, but now with an ecologically based, systematic approach that includes long-term planning, detailed record keeping and major investment in equipment and supplies. Although it is still only a small industry, the number of organic farmers is growing by about 12 percent per year and now stands at more than 12,000 nationwide.
Organic Farming in the U.S. Today
The USDA's Economic Research Service reports that in 1997, the latest year for which data are available, farmers in 49 states used organic production methods and thirdVparty organic certification services on 1.35 million acres out of a total of 828 million acres of farmland. Approximately two-thirds of the certified U.S. organic farmland was used for crops, and one-third was used as pasture.
Large farms, mostly located in the Midwest and West, produced processed tomatoes, organic wine grapes and other high-value crops on a commercial scale, whereas numerous small farms, concentrated in the Northeast, specialized in mixed vegetable production for direct marketing to consumers and restaurants.
While organic food can be found throughout the country, California was the leader in production of organic fruits and vegetables in 1997, followed closely by Arizona, Florida, Texas, and Washington in decreasing order of total yield. Farmers and ranchers in 23 states raised a small number of certified organic cows, hogs and sheep. New York, Wisconsin and Minnesota were the top producers of organic dairy cows.
Production: Organic vs. Conventional
As you can imagine, organic agricultural practices are quite distinct from those of "conventional" fanning.
Organic farmers:
feed soil and build soil matter with natural fertilizer to grow their crops use insect predators, mating disruption, traps and barriers to protect crops from
