    The day when the jobs were handed out was one of the most exciting for all the children in the class. Some jobs were more interesting than others. When giving them out, the teacher took account of(考虑) which pupils had been most responsible before. Among them Rita stood out. All the children knew Rita was the favorite to be given the best job of all: to look after the class dog.

But this year there was a big surprise. Each child received one of the normal jobs, like telling the time, cleaning the blackboard, looking after pets and so on. But Rita was given a little box with some sand and one ant （蚂蚁）. Most of her classmates felt sorry for her. Even her father became very angry with the teacher. However, Rita preferred to show the teacher by doing something special with such a boring job.

So Rita started studying all about her little ant. She gave the ant the very best food, and as a result it grew quite a bit bigger than anyone had expected.

One day a man came into the classroom. The teacher said with great joy, “This is Doctor Martinez. He has come to tell us a wonderful piece of news. Isn’t that right?”

“Exactly! "said the Doctor. “This class has best cared for the little ant given to you. You have been chosen to go with me, this summer, on a journey to the rainforest. Congratulations!”

That day everyone thanked Rita for having been so patient and responsible.
