Two careful and brave children--Benjamin,12, and his sister Emily, 11, found a stolen(被偷的) car in the woods（树丛） yesterday morning. The happy owner, Mrs Judy Roberts,said she would thank them by taking then out to dinner.
Both Benjamin and Emily like hiking. They were walking along a path through the woods near their home. And they noticed a car. They were surprised because very few people parked their cars there. They looked inside the car and there was nobody in it. The children thought something went wrong. They made a note of the type of the car and its colour. Benjamin also wrote down its number. When they went back to their school, they told their teacher about the car. The teacher reported （报告）it to the police.
Soon the police found the owner, Mrs Judy Roberts. “I really have to thank Benjamin and Emily. I’m going to write to the local newspaper and their headmaster（校长） to thank them” she said. Benjamin and Emily’s teachers felt proud(自豪的). “Benjamin and Emily are not only students but also good members of the community” they all said.
