I have a friend named Tina, one day, she took her dog to take a walk along the river bank, there are a lot of people by the river, she went to the other side of the river to go for a walk. She is a child splashing in the river, suddenly see there, a child fell into the river! She is very anxious, shouted at the shore, but it is far away from here, not to hear. She jumped into the river to save the child, but she can't swim, can be dangerous. At this time, the dog ran to the people there, to attract people to come over, saving the child and she.
