     We can achieve knowledge either actively or passivelr(被动地). We achieve it actively by

direct experience,by testing and piroving an idea,or by reasoning.

    We achieve knowledge passively by being told by someoneelse. Most of the learning that

takes place in the classroom and thekind that happens when we watch TV or read newspapers

ormagazines is passive. Conditioned as we are to passive leaning,it'snot surprising that we

depend on it in our everyday communication with friends and co-workers.

    Unfortunately,passive learning has a serious problem. It makes us tend to accept what we

are told even when it is little more than hear say and rumor(谣言).

    Did you ever play the game Rumor? It begins when one personwrites down a message but

doesn' t show it to anyone. Then the person whispers it,word for word, to another person.That

person,inturn,whispers it to still another, and so on, through all the peopleplaying the game. The

last person writes down the message word forword as he or she hears it. Then the two written

statements arec ompared. Typically, the original message has changed.

    That' s what happens in daily life. The simple fact that peoplerepeat a story in their own words

changes the story.Then,too,most people listen imperfectly. And many enjoy adding their own

creativetouch to a story,trying to improve on it,stamping(打上标记)it with their own personal

style. Yet those who hear it think they know.

    This process is also found among scholars and authors:Astatement of opinion by one writer

may be re-stated as fact by another,who may in turn be quoted by yet another；and this process

may continue,unless it occurs to someone to question the facts onwhich the origihal writer based

his opinion or to challenge the interpretation he placed upon those facts.
