     You're in a bit of a dilemma standing in front of the produce section of your local supermarket. In one
hand, you're holding a conventionally grown Granny Smith apple. In your other hand, you have one that's
been organically grown. Both apples are firm, shiny and green. Both provide vitamins and fiber, and both
are free of fat, sodium and cholesterol.
     The conventionally grown apple costs less and is a proven family favorite. But the organic apple has a
label that says "USDA Organic". Does that mean it's better? Safer? More nutritious? Several differences
between organic and non-organic foods exist. Become a better informed consumer for your next trip to the
supermarket.
     The word "organic" refers to the way farmers grow and process agricultural products, such as fruits,
vegetables, grains, dairy products and meat. Organic farming practices are designed to encourage soil and
water conservation and reduce pollution. Farmers who grow organic produce and meat don't use conventional
methods to fertilize, control weeds or prevent livestock disease.
      Here are other differences between conventional farming and organic farming:
Conventional farmersOrganic farmers
Apply chemical fertilizers to promote plant
growth.
Apply natural fertilizers to feed soil and
plants.
Apply insecticides to reduce pests and disease.Use beneficial insects and birds to reduce pests and
disease.
Give animals antibiotics (抗生素), growth
hormones
(激素) and medications to prevent disease
and promote growth, housing.
Give animals organic food and allow them
access to the outdoors. Use preventive
measures-such as a
balanced diet and clean housing-to help
minimize disease.
     * Organic or not? Check the label.
     The U.S. Department of Agriculture (USDA) has established an organic certification program that requires
all organic foods to meet strict government standards. These standards regulate how such foods are grown,
handled and processed. Any farmer or food manufacturer who labels and sells a product as organic must be
USDA certified as meeting these standards. Only producers who sell less than $5,000 a year in organic foods
are exempt (免除) from this certification.
     If a food bears a USDA Organic label, it means it's produced and processed according to the USDA
standards. The seal is voluntary, but many organic producers use it.
1. The main purpose of the passage is ______.
A. to promote the sales of organic food
B. to inform people organic food is better for their health
C. to persuade people to become informed consumers
D. to compare conventional and organic foods
2. According to the passage, the conventionally grown apple ______.
A. costs less but tastes worse than an organic one
B. doesn't look the same as an organic one
C. has proven itself acceptable by the family
D. contains more fat, sodium and cholesterol
3. Which of the following methods belongs to organic farming?
A. Using chemicals to kill insects and prevent disease.
B. Using rotted plants as fertilizer to promote plant growth.
C. Using growth hormones to speed up animals' growth.
D. Using insecticides to reduce insects and disease.
4. From the passage we know the organic certification program _______.
