Mrs Wen had1 two children, Janmes and William. The boys were always fighting2, both at home and at school.

　　One day, they fought3 again at school. Their teacher called Mrs Wen and told her about the fighting.

　　"Oh, I have had enough!" said4 Mrs Wen after she put down the phone. "Why can't they help each other and stop fighting?"

　　When the boys came5 home that day, Mrs Wen took6 some chopsticks from the kitchen.

　　"Try and break these," she told them. Neither7 of them could8 break the chopsticks. Then she gave9 them one chopstick each.

　　"Now try and break it, "she said. They both broke10 the chopstick easily11.

　　"You see," said Mrs Wen, "We are like the chopsticks. We are only strong when we help each other. "

　　After that, they never fought again.
