At
the end of the term, our ethics(伦理学) professor gave us a
test. He had told us {#blank#}1{#/blank#} (expect) one and had warned us it would be included
in the final grade.
The
test began. Sure enough, I was {#blank#}2{#/blank#} confident that I finished all the
questions after forty{#blank#}3{#/blank#} (minute) except the very last one: What is the name
of the woman who cleans the lecture hall?
I
thought it was {#blank#}4{#/blank#} joke. I'd seen the woman many times. She'd been working
in the building for at least a year. She is short {#blank#}5{#/blank#} dark hair, in her fifties,
and we'd even smiled at each other once or twice. But I didn't know {#blank#}6{#/blank#} (she)
name because I'd never thought of asking her. I handed in my test paper and the
last question {#blank#}7{#/blank#} (leave) unanswered-hoping the final result wouldn't be
influenced too {#blank#}8{#/blank#} (bad) because of it. But then one student put up his hand.
He hadn't finished the test, {#blank#}9{#/blank#} "I'm just wondering," he said,
"will it really change my grade if I don't complete the last
question?" "Certainly," our professor {#blank#}10{#/blank#} (smile).
"In
your future jobs ..."
I've
never forgotten that lesson, I also learned that the cleaner's name was Sherry.
