Passage1
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 with them. He does his best to make his classes lively and interesting.
One day he carefully explained chemical reaction 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, 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 it has gone?”
The classroom was 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!”
Passage10
One day Mr. Jackson took Paul to his favourite restaurant. It was a French restaurant. The waiter was from France, but he didn’t speak to them in French. “Would you like to see the menu?” he asked in a kind way. “Yes, please.” Mr. Jackson said.
The waiter gave them a menu each. They studied them. “You can spend only twenty-five dollars,” Mr. Jackson told his son. The waiter asked Paul, “What would you like, young man?”
“How much is the tomato soup?” Paul asked.
“Six dollars,” the waiter said. “It’s very good.”
“How much is the duck with orange?” Paul asked next.
“Fifteen dollars,” the waiter said.
“How much is the chocolate ice cream?”
“Six dollars,” the waiter said.
Paul added it up quickly. Six plus fifteen plus six is twenty-seven. He though he could have the duck and the soup, or the duck and the ice cream. “I’ll have the duck and the chocolate ice cream, please.” He said to the waiter.
Paul said to his father, “My meal will cost only twenty-one dollars. Can I keep other four dollars?” His father laughed, “No, Paul.” He said. “Leave it for the waiter.”
