20. They are known that colds can be avoided by eating the right kind of food and taking exercise regularly. A B C DV. Read the passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.In the world today, particular in the two most industrialized areas, North America and Europe, recycling is the bignews. People are talking about it, practicing it, and discovering new ways to be sensitive to the environment. Recyclingmeans finding ways to use products a second time. The motto of the recycling movement is “Reduce, Reuse, Recycle”.The first step is to reduce garbage. In stores, a shopper has to buy products in blister packs, boxes and expensiveplastic wrappings. A hamburger from a fast food restaurant comes in lots of packaging: usually paper, a box and a bag.All that packaging is wasted resources. People should try to buy things that are wrapped simply, and to reuse cups andutensils. Another way to reduce waste is to buy high-quality products. When low-quality appliances break, manycustomers throw them away and buy new ones - a loss of more resources and more energy. For example, if a customerbuys a high-quality appliance that can be easily repaired, the manufacturer receives an important message. In the sameway, if a customer chooses a product with less packaging, that customer sends an important message to themanufacturers. To reduce garbage, the throw-away must stop.The second step is to reuse. It is better to buy juices and soft drinks in returnable bottles. After customers empty thebottles, they return them to the stores. The manufacturers of the drinks collect bottles, wash them, and then fill themagain. The energy that is necessary to make new bottles is saved. In some parts of the world, returning bottles formoney is a common practice. In those places, the garbage dumps have relatively little glass and plastic from throw-away bottles.The third step being environmentally sensitive is to recycle. Spent motor oil can be cleaned and used again.Aluminum cans are expensive to make. It takes the same amount of energy to make one aluminum can as it does to runa color TV set for three hours. When people collect and recycle aluminum (for new cans), they help save one of the world’sprecious resources.
