我快要演讲了，谁能给我提供一些题材

Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old swimming hole behind his house.

In a hurry to dive into the cool water， he ran out the back door， leaving behind shoes， socks， and shirt as he went. He flew into the water， not realizing that as he swam toward the middle of the lake， an alligator was swimming toward the shore. His mother - in the house was looking out the window - saw the two as they got closer and closer together. In utter fear， she ran toward the water， yelling to her son as loudly as she could.

Hearing her voice， the little boy became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her， the alligator reached him.

From the dock， the mother grabbed her little boy by the arms just as the alligator snatched his legs. That began an incredible tug-of-war between the two. The alligator was much stronger than the mother， but the mother was much too pass
