What is intelligence anyway? When I was in the army I    21  an intelligence test that all soldiers took, and, against   22  of 100, scored 160．No one at the base had ever seen a figure like that, and for two hours they made a big fuss over me.
All my life I've been registering scores like that,    23  I have the complacent(洋洋自得的) feeling that I'm highly intelligent, and I expect other people to think so too. Actually, though, don't such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by people who    24     the intelligence tests - people with intellectual bents(天分) similar to mine?
For instance, I once had an auto-repair man, who, on these intelligence tests, could not   25  have scored more than 80,by my estimate. Yet, when anything went wrong with my car I hurried to him—and he always fixed it.
Well，then，suppose my auto—repair man   26  questions for some intelligence tests．By doing every one of them I'd prove myself a   27  ．In a world where I have to work with my    28   ，I'd do poorly．
Consider my auto—repair man   29   ．He had a habit of telling  30   ．One time he said. “Doc, a deaf and dumb man   31  some nails．Having entered a store，he put two fingers together on the counter and made  32    movements with the other hand．The clerk brought him a hammer．He   33   his head and pointed to the two fingers he was hammering．The clerk   34  him some nails．He picked out the right size and left．Well，Doc，the   35  man who came in was blind．He wanted scissors．   36  do you suppose he asked for them?" I lifted my right hand and made scissoring movements with my first two fingers．He burst out laughing and said，“Why, you fool，he used his    37   and asked for them.” Then he said smugly, "I've been    38    that on all my customers today." "Did you catch many?" I asked. "Quite a few," he said, "but I knew     39    I'd catch you." "Why is that?" I asked. "Because you're so goddamned educated, Doc, I knew you couldn't be very     40   ." And I have an uneasy feeling that he had something there．
