    Yesterday a school boy is daydreaming in class. Not knowing that he was doing, he put

a pen cap into his mouth. A few minutes late, he was terrified to find that he had swallowed

it! The teacher was shocking when the boy stood up and said, "I've just swallowed a pen

cap." He was quickly sent the nearest hospital. There a doctor examined him and said the best

treatment was to take some medicines so that the pen cap could pass natural. Three hours later

the boy successfully made it. "She is really lucky," said the doctor. "It's not rare that small

children put things into their mouths for a fun. It's very danger."
