What should we do if one of our classmates suddenly falls ill or gets injured? Here are some tips you should follow. But always remember to seek medical care after first aid if the injury is serious.

It was 3:21 a.m. when ten-year-old Glenn Creamer was woken up by the smell of burning. Except for the crack（爆裂声）of flames somewhere below, there was not a sound in the house.

As his father was away on business, Glenn was worried about his mother, his 14-year-old sister Karen and his 12-year-old brother Todd. He ran downstairs through the smoke-filled house to push and pull at Karen and Todd until they woke up. Then he helped them to the garden. There, his sister and brother took short and quick breaths and coughed.

Glenn raced back into his mother’s room. He found it impossible to wake her up and there was nobody to help Glenn carry her to the garden. But the boy kept calm.

Luckily the telephone in the bedroom was still working. Glenn called his father. After Glenn made sure his father would telephone the firemen and ambulance service, he went on saving his mother.

First he filled a bucket with water from the bathroom and threw water over his mother and her bed. In this way, she would be kept away from the fire before the firemen arrived. Then, he went back to the garden.

Later, he heard the fire engine coming up. But how would the firemen find his mother in the smoke-filled house where fire had almost covered the ground floor?

Fetching a ball of string（绳）from the garage Glenn raced back to his mother’s room. He tied one end of the string to her hand. Then he began to run back. He laid out the string as he went through the hall and back out into the garden.

Minutes later, he told the Fire Chief John Coughlan, “The string will lead you to my mother.” Mrs Creamer was saved finally.

James Dawson, a fifth grader at an American middle school, was eating his lunch one day, when he accidentally swallowed (吞咽) a piece of the plastic on his food. He choked (噎住) and felt hard to breath. Great fear quickly caught him. He thought he was going to die.

Thankfully, a boy James didn’t know at all happened to be walking by at just the right time. Luckily, the 11-year-old boy, Arad, knew exactly what to do. He saw James taking hold of his throat, and noticed that the his face had turned completely purple. So he ran behind James immediately and started doing the Heimlich maneuver (海姆立克腹部冲击法). In the end, James shouted, “It’s out! It’s out!”

Arad said he’d learned how to do the Heimlich from a book several years before. So he understood the physics behind it. “It is to push air through the airway (气道) to throw whatever is there out,” he explained.

That night, James went home and told his mother the whole story. She wanted so badly to find the child who’d saved her son that she posted what had happened on the Internet. Later, Arad’s mother saw it and wrote her back.

Arad and James became close friends. “He knew what to do and I’m glad he knew what to do,” James said, “or I probably wouldn’t be talking.”
