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. It is not uncommon for shoppers in the developed world to throw away as much as half the food they buy. The tendency to indulge is driven by marketing schemes that offer “buy one, get one free,” even if we really do not need that second item. It is hard to say no to a bargain. 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. The study of shopping habits is extremely advanced and corporations live and die by their data. If consumers make a conscious effort to change their habits, (a)retailers will notice. 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. Again, it is all abont snding sianele Tt is unrealistic to expect to eimimate an waste in food. But the idea that one-half of food production is wasted-and that much of it is because of aesthetic reasons is intolerable. 1.What does phrase (a) imply? (4点) ア. retailers will notice the importance of consumers' shopping and eating habits イ. retailers will notice shoppers don't want so many items ウ. retailers will notice they should change their marketing schemes 2. Fill blank (b) with the most suitable word. (4 点) 3. Choose the best answer to fill each blank.

数学についてです。 写真の赤字の部分が分かりません。 x'=r cos(α+π/3)、y'=r sin(α+π/3) の部分です! αはOP'とx軸正の部分との角を表すんですよね…?図を見ると、x'=r cos(π/3−α)、y'=r sin(π/3−α) が正しいと思... Read More
