We achieve it actively by direct experience, by testing and proving an idea, or by reasoning. We achieve knowledge passively by being told by someone else. Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive. Conditioned as we are to passive learning, it’s not surprising that we depend on it in our everyday munication with friends and coworkers. Unfortunately, passive learning has a serious problem. It makes us tend to accept what we are told even when it is little more than hearsay and rumor(謠言 ). Did you ever play the game Rumor? It begins when one person writes down a message but doesn’t show it to anyone. Then the person whispers it, word for word, to another person. That person, in turn, whispers it to still another, and so on, through all the people playing the game. The last person writes down the message word for word as he or she hears it. Then the two written statements are pared. Typically, the original message has changed. That’s what happens in daily life. The simple fact that people repeat a story in their own words changes the story. Then, too, most people listen imperfectly. And many enjoy adding their own creative touch to a story, trying to improve on it, stamping（打上標(biāo)記） it with their own personal style. Yet those who hear it think they know. This process is also found among scholars and authors: A statement of opinion by one writer may be restated as fact by another, who may in turn be quoted by yet another。 West Wind, appeared in was followed by The Good Earth (1931),Sons(1932),and A House Divided(1935),together forming a trilogy(三部曲 )on the stories of the family of Wang. The Good Earth stood on the American list of bestsellers for a long time and earned her several awards, including the Pulitzer Prize and the William Dean Howells Medal. She also published The first Wife and Other Stories(1933),All Men are Brothers(1933),The Mother(1934),and This Proud Heart(1938).The biographies(傳記 )of her mother and father, The Exile and Fighting Angel, were published in 1936 and later brought out together under the title of The Spirit and the Flesh(1944). Pearl Buck’s works after 1938 are too many to speak about. Her novels have continued to deal with the differences between East and West. Her interest has spread to such countries as India and Korea. Pearl Buck was active in many charity(慈善 )anizations。 A When I was growing up, I was ashamed to be seen with my father. He was severely disabled and very short, and when we would walk together, his hand on my arm for balance, people would stare. If he ever noticed or was bothered, he never let it on. It was difficult to coordinate(協(xié)調(diào) )our stepshis slow, mine impatientand because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace, I will try to adjust to you.” He never talked about himself as an object of pity, nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him. Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know accurately what a “good heart” is. But I know the times I don’t have one myself. Unable to engage in many activities, my father still tried to participate(參加 ) in some way. I now know he participated in some things indirectly through me, his only son. When I played ball(poorly),he “played” too. When I joined the navy ,he “joined” too. And when I came home on leave ,he saw to it that I visited his office. Introducing me, he was really saying, “This is my son, but it is also me, and I could have done this, too, if things had been different.”Those words were never said aloud. He has been gone many years now, but I think of him often. I wonder if he sensed my unwillingness to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I plain about small affairs, when I am envious of another’s good fortune, when I don’t ha ve a “good heart”. At such times I put my hand on his arm to regain my balance, and say, “You set the pace, I will try to adjust
