Mr. Green was our science teacher. On the first day of our 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 3 to me, I was surprised and sad. There was a big red "X" through each of my answers. I failed. But how come? Anyway on the test paper, I had written down 4 Mr. Green said in class.

"The zeros on your papers will be 10 in your grade books, " he said. And he did it.

Through this 11 , Mr. Green hoped that we would learn something. Teachers and books are not always12 . 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 are 13 in 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!
