LESSON 3 Paragraph 3 An Appalling Waste of Food (教科書 pp. 18~19) クラス 番号 名前 130 Read the passage and answer the questions below. Obviously, we need to pay more attention to shopping and eating habits.

We need to learn to say “no" more effectively. Indeed, consumers need to be more discerning throughout their shopping experience and be vocal in words and deeds.

Consumers can also make better use of food banks and other resources that help the hungry and (b )fortunate. On the individual level, they need to be conscious of the ( b ) fortunate before they throw good food out. And, they too should be encouraging the organizations they work for and the places they shop to be equally solicitons of the noody Education should emphasize the neea w avoid wasting food.
