Organic farming to crops growing with natural rather than chemical fertilizers. 题目和参考答案——青夏教育精英家教网—

Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics（抗生素）or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible.
Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food.
They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets.
However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic.
Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus（共同看法）is that, in the short term, organic farming is less damaging for the following reasons:
● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife.
● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals.
● Organic farms are more energy efficient and produce less waste.
Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food.
However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive.
1. Early consumers knew what food was “organic” by _______.
A. firsthand experience                                     B. the “certified organic” label tag
C. its packaging                                                      D. examining its organic certification
2. We can infer that _______.
A. in America, organic food can only be bought in small stores or farmers’ markets
B. organic food is also available in large supermarkets at present
C. organic food is produced by large-scale farms
D. organic food is often beautifully packaged
3. According to the passage, organic food is considered as _______.
A. junk food              B. delicious snacks               C. green food      D. conventional food
4. What is the main idea of the last paragraph?
A. The benefits of organic food.                               B. The cost of organic food.
C. The disadvantages of organic food.                   D. Organic food and conventional food.
5. Which of the following statements does NOT support the view that organic farming is more environment-friendly?
A. Organic food is generally thought to be more nutritious.
B. Organic farms are more energy efficient and produce less waste.
C. Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals.
D. Organic farms do not release synthetic pesticides into the environment.

Farmers and gardeners have long used greenhouses to extend the growing season in cold weather. Now, hoop houses are gaining popularity. Some hoop houses are rounded; others are shaped more like a traditional house.

A hoop house is basically a metal frame covered with plastic or other all-weather material. A common design looks like a high tunnel. Unlike a greenhouse, which uses a heating system, a hoop house is heated by the warmth of the sun.

Now, the United States Department of Agriculture has announced a program to help farmers who want to build hoop houses. The department has been supporting a project in Michigan. That state has a short growing season. As part of the research project, nine farmers were given materials and trained how to build and use a hoop house. The results showed that well-managed hoop houses can grow high-quality crops.

However, crops are not the only things that grow well. The research found that weeds grow faster in a hoop house. Weeding (除草), seeding and watering requires at least as much work as crops grown in the open air. The researchers also advise growers to add compost（堆肥） material to the soil in hoop houses to build nutrients.

Eliot Coleman is an organic farmer and a writer in Maine who has helped popularize the idea of four-season farming. His ideas about hoop houses sounded good to John Biernbaum in the Horticulture（园艺）Department at Michigan State University.

Professor Biernbaum tried hoop houses on the Student Organic Farm at Michigan State and had success. Project director David Conner says it was a "test drive（试车）" for the research on private farms. The agricultural economist points to the demand for locally grown crops. "People are hungry for good, fresh vegetables," he says.
