Exercise 1. Read the text about organic food and write the letters of the paragraphs (A-D) which describe the given statements. 1. The benefits of organic food. _________ 2. Organic food is expensive. _________ 3. Ensuring the originality of organic food. _________
4. Professional views on organic food. _________
A. Organic food is very popular these days. It can also be very costly. Some organic food costs twice as much as non-organic food. Parents of young children, and even some pet owners, will pay high prices for organic food if they think it's healthier.
B. There is one main difference between organic and non-organic food. Organic farms do not use agricultural chemicals such as pesticides that stop insects from damaging crops. In many countries foods that claim to be organic must have special labels that guarantee that they are organic. C. Is organic food safer and more nutritious? This is an important part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals can cause serious illnesses like cancer, but there isn't much evidence proving this is true.
D. Many doctors think it's more important to stop dangerous bacteria from contaminating foods. These bacteria can contaminate both organic and non-organic fruit and vegetables, and doctors recommend washing carefully before eating it. Meat, fish and chicken can also become contaminated, so washing them is also very important. Many doctors also believe we should reduce the amount of sugar in our diets, and there is a lot of evidence to support this idea.
