Mr. Jackson
was our science teacher. On the first day of class, he gave us a talk about an
animal called wampus. He told us that the wampus lived on earth millions of
years ago during the Ice Age and died out because of the change of climate(气候). We all listened
carefully and took 1 of everything he said. Later we had a 2.
When the
exam paper was 3to me, I was surprised and sad, there
was a big red "×" through each of my answers, I
failed. But how come? 4, on the test paper, I had written down
5 Mr. . Jackson said in
class.
Then I
realized that no one 6 the exam at all. What had happened?
"Very
simple," Mr. Jackson explained. "I had 7 all that story about the wampus. There had
never been any such animal, so the information in your notes was not correct. Do
you expect to get 8 marks for incorrect answers？"
There was
no need to say we were 9. What kind of test was this? What kind
of teacher was he?
How could
we believe he gave us so much information about an animal that had not been
there at all? How was it possible 10 us students to doubt what the teacher taught
us?
"The
zeroes on your papers will be 11 in your grade books,"
he said. And he did it.
Through this experience, Mr. Jackson
hoped that we would learn something. Teachers and books are not always 12. In fact, no one is. He told us not to
let our mind go to sleep. Instead, we should keep thinking all the time and
speak up if we think there are13in our teachers' words or in books.
We should
14 the habit of doubting, and the ability to
decide by ourselves. What a special 15 he gave us.
