PROBLEM: Article: Deng Nannan, 15, used to hate drinking milk for breakfast. But she had to drink it because her mom, as well as many others, said that milk was good for her growing body. Besides, milk and bread made up a convenient diet that saved her parents a lot of time after Deng entered junior school and had to arrive at school early in the morning. After that, Mengniu and Yili became her favorite brands of morning milk and yoghurt after dinner. However, she has been forced to change her diet since the recent milk crisis. Many best-selling milk brands such as Mengniu, Yili and Bright were discovered to contain melamine , which is usually used to make plastic. The bad milk products have sickened more than 5,300 babies and killed four. "I shifted to rice porridge," she said. "My mom has to get up at 5:50 am to prepare my breakfast and make sure that it cools down when I get up." Deng has become addicted to milk, so she doesn't quite enjoy her morning meal these days although she knows that it's a tiring job for her working mom. "I'll turn back to Mengniu and Yili when they finally improve their products," she said. However, right now Deng's mom tries to adjust her eating habits by cooking different foods. Besides rice porridge, noodles, egg soup and soybean milk are prepared as her breakfast.
Answer: Because milk becomes more and more expensive.

PROBLEM: Article: One day while shopping in a small town in southern California,it was my misfortune to be approached by a clerk whose personality conflicted with mine. He seemed most unfriendly and not at all concerned about my intended purchase. I bought nothing,and marched angrily out of the store. My hostility toward that clerk increased with each step. On the outside,standing by the road,was a darkskinned young man in his early twenties. His expressive brown eyes met and held mine,and in the next instant a beautiful, dazzling smile covered his face. I gave way immediately. The magnetic power of that smile dissolved all bitterness within me,and I found the muscles in my own face happily responding . "Beautiful day,isn't it?"I remarked,in passing. Then,I turned back."I really owe you a debt of gratitude ,"I said softly. His smile deepened, but he made no attempt to answer.A Mexican woman and two men were standing nearby.The woman stepped forward and volunteered, "Sir, but he doesn't speak English.Do you want me to tell him something?" In that moment I felt transformed .The young man's smile had made a big person of me.My friendliness and good will toward all mankind stood ten feet tall. "Thank you?" The woman seemed slightly puzzled. I gave her arm a friendly pat as I turned to leave."Just tell him that," I insisted."He'll understand.I am sure !" Oh, what a smile can do! Although I have never seen that young man again, I shall never forget the lesson he taught me that morning.From that day on, I became smile-conscious, and I practice the art anywhere and everywhere, with everybody.
