One day in class,the teacher held up an apple,stood at the front of the class and said, "Please smell the smell in the air !What can you smell?"
One student put up his hand and said, "I can smell it. It is the smell of an apple. "
The teacher passed by each of the students with the apple in hand and said, "Smell again to see if the smell of the apple is still in the air. " Half of the students raised their hands to show that they could smell it. The teacher went back to the front of the classroom and asked again if the students could smell the apple.
Everyone put up their hand but one little girl didn't. The teacher came to the girl and asked, "You really can't smell the apple?"
The girl answered, "No,I can't smell it. I don't think it's a real apple. "
The teacher smiled at the girl and said to the class, "She is right!This is not a real apple. "
All of the other students' eyes were wide open. They also might have thought that the apple was not real,but they didn't have the self-confidence(自信) to speak up. They just followed the first student.
