完形填空。

     In the clinic, I asked if Michael could be retested, so the specialist tested him again. To my   1   , it was
the same score.
     Later that evening, I   2 told Frank what I had learned that day. After talking it over, we agree that we
knew our   3 much better than an IQ (智商) test. We   4 that Michael's score must have been a   5   and
we should treat him   6   as usual.
     We moved to Indiana in 1962, and Michael studied at Concordia High School in the same year. He got   7
grades in the school, especially   8 biology and chemistry, which was a great comfort.
     Michael   9 Indiana University in 1965 as a pre-medical student, soon afterwards, his teachers permitted
him to take more courses than 10 . In 1968, he was accepted by the School of Medicine, Yale University.
     On graduation day in 1972, Frank and I 11 the ceremony (典礼) at Yale. After the ceremony, we told
Michael about the   12 IQ score he got when he was six. Since that day, Michael sometimes would look at
us and say 13 , "My dear mom and dad never told me that I couldn't be a doctor, not until after I graduated
rom medical school!" It is his special way of thanking us for the   14 we had in him.
     Interestingly, Michael then   15 another IQ test. We went to the same clinic where he had   16 the test
eighteen years before. This time Michael scored 126, an increase of 36 points. A result like that was supposed
to be 17 .
     Children often do as   18   as what adults, particularly parents and teachers,   19 of them. That is, tell a
child he is "  20 ", and he may play the role of a foolish child.
