    It was often the most exciting for the children when the teacher gave every child a job in the class. The children would be responsible for the rest of that school year. Rita was a kind and quiet girl. Last year she did the best. She was the favorite to be given the best job---to look after the class dog. But this year there was a big surprise. Each child received one of the normal jobs, like preparing the books for the lessons, cleaning the blackboard or looking after one of the pets. But Rita's job was very different. She was given a little box with some sand and one ant. Although the teacher said that this ant was very special, Rita still felt disappointed.                                                    

"I will turn this little task into something great," Rita said to herself. She started to study everything about the little ant, gave it the best food and made the box perfect. The ant ended up growing quite a little bigger.

One day, the teacher announced(宣布）that Rita’s class was chosen to the tropical rainforest to study all kinds of insects in summer, because the class looked after the little ant well.                                                     

The class was filled with joy. Everyone thanked Rita for having been so patient and responsible. And children learned that you have to know how to be responsible for the given tasks even the smallest ones.
