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（敌意） 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（给人印象深刻的） smile covered his face. I gave way immediately. The magnetic（磁力的） power of that smile dissolved （溶解）all bitterness within me，and I found the muscles in my own face happily responding（回应）.
“Beautiful day，isn't it？”I remarked，in passing. Then，I turned back.“I really owe you a debt of gratitude（感谢），”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（改变）．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．

(答案→)A 解析：本文讲述的是在一次购物中，作者和一位个性与自己冲突的店员发生了冲突，使作者特别的不快，在生气的离开了店子之后，作者遇到了一位年轻男人，这个年轻男人的微笑瞬间化解了作者所有的不快，从那之后，作者学会了无论在任何地方，对待任何人都应该充满微笑。【小题1】细节题。由第一段二、三句He seemed most unfriendly and not at all concerned about my intended purchase. I bought nothing，and marched angrily out of the store.店员看起来非常不友好，根本不搭理作者要买的东西，由此，作者没有买任何东西，生气地离开了店子。故选A【小题2】推断题。由第二段最后一句The magnetic（磁力的） power of that smile dissolved （溶解）all bitterness within me，and I found the muscles in my own face happily responding（回应）.在店子外面，一个年轻男士的微笑溶解了作者所有的不快，并且作者发现自己也露出了笑脸。故这句话的意思是作者微笑地回应这个年轻的男人。故选D【小题3】推断题。由第四段最后两句In that moment I felt transformed（改变）．The young man's smile had made a big person of me．My friendliness and good will toward all mankind stood ten feet tall．在那一时刻，作者发生了改变，这个年轻男人的微笑使作者变得大度、宽容，作者将对所有人都充满友谊和善意。可知，作者之所以向这个年轻的男士说谢谢，是因为作者从这个男士身上学到了重要的一课。故选D【小题4】主旨题。由文章最后一句From that day on, I became smile-conscious, and I practice the art anywhere and everywhere, with everybody．从那天起，作者开始有意识地微笑，并且无论在任何地方都在练习这种行为，故可知，这篇文章的主旨是我们应该对他人充满微笑。故选C。
