      Charlie studied in a famous college for four years. He studied hard and did well in all his subjects. He

hoped to become a good teacher. This year he left the college and began to work in a middle school. He likes

his students and is strict (严格的) with them. He does his best to make his classes lively and interesting. 

      One day he carefully explained a chemical reaction (反应) to the students of Grade 2 in the chemistry

lab. 

      "Be careful, everyone," he said loudly. "Before I make the experiment, there're twenty five atoms of

carbon (碳原子), but after I finish it, there're twenty four atoms of carbon left!" He stopped to watch the

classroom and hoped his students would go on explaining it. But the young men looked at each other and

nobody answered him. He had to ask, "What happens? What makes the atom lost?"

      The classroom was very quiet and none of the students looked at their teacher. "Who can tell us where

it has gone?" Suddenly a soft voice came from the back row, "We did not see anybody leave the lab!"
