Mr. Whitson taught sixth-grade science．In his first class，he gave us a __1__ about an animal called “cattywampus”，which died out during the Ice Age．He passed __2__ a skull （头盖骨）as he talked．We felt proud for feeling it，took __3__ and later had a quiz．
When my paper returned，I was shocked at the big red cross through __4__ of my answers．Why? I had written down exactly what he said．
Very simple．Mr. Whitson __5__．He had made up the story about the cattywampus．Needless to say，we were extremely __6__．
We could have _7__ him out，he said．__8_，he told us _9__ remains of the animal had ever been found at the very moment he was showing us the skull，_10__ a cat's．So，why didn't we __11__ his description（描述）about its color and other facts，especially the ridiculous（荒唐的）__12 _ he gave it? The zeros would be recorded in his __13__ book．He hoped we would learn something from this __14__．Teachers and textbooks were not always correct and we shouldn't let our mind sleep，but speak up what we thought _15__．
We _16__ our skepticism（怀疑主义）into other classed，but it caused __17__ for the teachers who weren't used to being challenged．I've kept in mind what Mr. Whitson gave me-the __18__ to look people in the eye and tell them they were wrong．
Not everyone sees the __19_ in this．I once told a teacher about it and she was surprised，saying "He shouldn't have tricked（欺骗）you like that．" I looked at her right in the __20__ and told her she was wrong．
