     Charlie was spending his summer holidays by the sea. One day he climbed over some rocks. He was

looking for some crabs (螃蟹) for supper. He took off his shorts and put them on a rock.

     The afternoon went quickly. Time was flying by. Look! The sea was coming in fast. It was over some

of the rocks now.

     Charlie looked up. "It's getting late. Oh dear! Look at the sea. Where are my shorts now?" he thought. He

saw them on a rock. Oh dear! The rock was an island! Now he must swim and got them.

     Charlie jumped into the sea and started swimming. He reached the rock and put his shorts on his head.

Then he started swimming back. Oh no! The sea was too strong for Charlie. It was pulling him away from

the beach. 

     "Help!" he called. "I can't get back."

      Luckily, a boat was coming by. The people in the boat saw Charlie and heard his call for help.

     "Are you all right?" asked the woman in the boat.

    "No! I can't swim back. The sea is too strong."

    The woman stopped the boat and she and a girl pulled Charlie into the boat. He threw his shorts into the

boat too. Then they turned the boat Bound and took Charlie back to the beach.

     "That was lucky," said the woman.

     "Thank you very much," said Charlie. 

     "Be careful next time," said the woman. "The sea is usually very strong near these rocks." 

     "Next time, I'm going to keep my shorts in my bag," said Charlie. "Better safe than sorry!"
