Organic food is now a huge market segment, driven by consumer demand for food that’s hea

lthier.

The biggest misconception held by many organic lovers is that organic produce is not grown with fertilizers (肥料) or pesticides (杀虫剂). That’s simply wrong. Organic fertilizers and pesticides are manufactured by all the major producers. Pests attack crops whether they’re certified organic or not; and all plants take nutrients (营养物) out of the soil that have to be replaced.

Many think organic farms handle that through soil management. And so they do, but so do all farms. Every farm rotates crops as much as possible to keep the soil healthy and reduce the spread of pest; by no means is this unique to organics. It’s been a farming fundamental for centuries.

Chemicals are one of a farm’s biggest expenses, and both organic and conventional farms strive to reduce that expense. Modern agriculture depends on efficient fertilizers that deliver the needed nutr

1What is a traditional method used to keep the soil healthy？

A、Avoiding too much use of chemicals.

B、Replacing soil nutrients with fertilizers.

C、Using the soil for organic produce only.

D、Rotating crops as much as possible.

2What is one characteristic of organic practices？

A、They use no fertilizers or pesticides.

B、They use more efficient fertilizers.

C、They ban the use of new seed strains.

D、They adopt the latest farming techniques.

3From Paragraph 6 (the paragraph beginning with “at the end of the day, …”), we can infer that ______________.

A、organic food is no different from conventional produce

B、the quality of organic produce can be highly unstable

C、the results of the tests in the videos are not fair enough

D、volunteers participating in these tests are not qualified

4At the end of the passage, the writer tends to suggest that _____________.

A、the benefits of organic food are overstated by marketing

B、organic practice involves no scientific knowledge at all

C、people should be practical and consume less organic food

D、it is easy for people to be fooled by bad science today

5What is the main purpose of the passage？

A、To compare organic food with conventional produce.

B、To correct people’s wrong beliefs about organic food.

C、To explain why organic food is so popular with people.

D、To convince that conventional produce is better for health.

Organic food: Why？ 1. Europeis now the biggest market for organic food in the world, expan

Organic food: Why？

1. Europeis now the biggest market for organic food in the world, expanding by 25percent a year over the past 10 years. So what is the attraction of organicfood for some people？ The really important. thing is that organic sounds more"natural". Eating organic is a way of defining oneself as natural,good, caring, different from the junk-food-eating masses.

2. Unlike conventionalfarming, the organic approach means farming with natural, rather than man-made,fertilisers and pesticides. Techniques such as crop rotation(轮种)improve soil qualityand help organic farmers compensate for the absence of man-made chemicals. As amethod of food produc- tion, organic is, however, inefficient in its use oflabour and land; there are severe limits to how much food can be produced.Also, the environmental benefits of not using artificial fertilisers are tinycom- pared with the amount of carbon dioxide emitted(排放)by transportingfood.

3. Organic farming is oftenclaimed to be safer than conventional farming. Yet studies into organic farmingworldwide continue to reject this claim. An extensive review by the UK FoodStandards Agen- cy found that there was no statistically significant differencebetween organic and conventional crops. Even where results indicated there wasevidence of a difference, the reviewers found no sign that these differenceswould have any noticeable effect on health.

4. The simplistic claimthat organic food is more nutritious than conventional food was always likelyto be misleading. Food is a natural product, and the health value of differentfoods will vary for a number of reasons, including freshness, the way the foodis cooked, the type of soil it is grown in, the amount of sunlight and raincrops have received, and so on. Likewise, the flavour of a carrot has less todo with whether it was fertilised with manure(粪便) or something out of a plastic sack than with thevariety of carrot and how long ago it was dug up. 5. The notion that organic food is saferthan "normal" food is also contradicted by the fact that many of ourmost common food are full of natural toxins(毒素). As one research expert says : "People thinkthat the more natural something is, the better it is for them. That is simplynot the case. In fact, it is the opposite that is true: the closer a plant isto its&39;natural state, the more likely it is that will poison you. Naturally,many plants do not want to be eaten, so we have spent 10,000 years developingagriculture and breeding out harmful traits from, crops. "

Organic FoodOrganic farming was among the fastest growing segments of U.S. agriculture dur

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. Be fore 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, which was used as munitions, became useful as fertilizer, and organophosphates used for nerve gas were later used as insecticide.

These days, farmers are switching to organic agriculture once again, but now with an eco logically 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 third-party 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" farming.

Conventional farmers:

apply chemical fertilizers to the soil to grow their crops

spray with insecticides to protect crops from pests a

A．Y

B．N

C．NG

Are organically grown foods the best food choices？ The advantages claimed for such foods o
ver conventionally grown and marketed food products are now being debated. Advocates of organic foods frequently proclaim that such products are safer and more nutritious than others.

The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the greater number of written material advancing such claims make it difficult for the general public to sep arate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form. the basis for folklore.

Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that crops grown with organic fertilizers are nutritionally superior to chose with chemical fertilizers, that untreated grains are better than fumigated grains, and the like.

One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern ff consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.

The author implies that there is cause for concern if consumers with limit ed incomes buy organic foods instead of conventionally grown foods be cause ______ .

A．organic goods can be more expensive but are often no better than conventionally grown foods

B．many organic foods are actually less nutritious than similar conventionally grown foods

C．conventionally grown foods are more readily available than organic foods

D．too many farmers will stop using conventional methods to grow food crops

Part A

Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.

Health food is a general term applied to all . kinds of foods that are considered much healthful than the types of foods widely sold in supermarkets. For example, whole grains, dried beans and corn oil are health foods. A narrower classification of health food is natural food. This term is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas refined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health foods is organic food, used to describe food that has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens that are treated only with organic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically grown feed and that are not injected with hormones are organic foods.

In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the allegations that processed foods contain chemicals, some of which are proven to be toxic, and that vitamin content is greatly reduced in processed foods.

Bread is typically used by health food advocates as an example of a processed food. First, the seeds from which the grain is grown are treated with bichloride of mercury, an extremely toxic poison. Later, the grain is sprayed with a number of very toxic insecticides and pesticides. After the grain has been made into flour, it is bleached with nitrogen trichloride or chlorine dioxide, both toxic. Next, a dough conditioner, usually ammonium chloride, is added along with a softener, polyoxymethylene. The conditioner and softener ate poisons, and in fact, the softener has sickened and killed experimental animals.

A very toxic antioxidant is now added along with coal tar, a butter-like yellow dye. Finally calcium propionate, an anti-fungal compound, is added to keep the bread from getting moldy.

Other foods from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want--even if it is poisonous. The alternative？ Eat health foods, preferably the organic variety.

What was the main idea of this passage？

A．Health foods.

B．The processing of bread.

C．Organic gardens.

D．Poisons.

Are organically grown foods the best food choices？ The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods — a term whose meaning varies greatly — frequently proclaim that such products are safer and more nutritious than others.

The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development.

第10题
Genetically-modified (GM) foodstuffs are here to stay.That’s not to say that food prod
uced by conventional agriculture will disappear, but simply that food-buying patterns will polarize: there will be a niche market for conventional foodstuffs just as there is for organic food.It may even be that GM food will become the food of preference because consumers come to appreciate the health benefits of reduced pesticide use.

Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.

The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.

The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.

It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.

6. According to the passage, food supplies have been increased by all the following except_____________.

A.pesticides

B.artificial fertilizers

C.improved varieties

D.transportation

7.How many chemicals are still less familiar to the scientists？()

A.20,000.

B.1,000

C.19,000

D.21,000.

8.Why will people prefer GM food in the future？()

A.Because it uses less pesticides.

B.Because it is much cheaper.

C.Because the production is increased.

D.Because it is organic food.

9.Which of the following is NOT true？()

A.By 2050, the world population will grow to ten or eleven billion.

B.In the 21st century, GM food will take the place of conventional food.

C.More and more people will reduce the overall land available for farming.

D.More and more people will consume more food and occupy more space.

10.The author’s attitude towards GM food is _______.

A.negative

B.positive

C.critical

D.uncertain
