It was a clear day. Lucas and his brother, Alex sat on the beach and watched the clouds drift across the sky."I'll race you to the water!" said Lucas.

The boys raced toward the water. Lucas sprinted ahead into the water, splashing Alex as he went.

The boys jogged along the beach for a while. Then, they waded in the shallow water.

Suddenly Lucas stopped and stared at the ocean. "Look! Something is splashing in the water. Sharks!"

"What?"

"I said there are sharks!"

"Those aren't sharks," replied Alex. "They're dolphins!".

The boys watched the dolphins leap and dive into the water. Then the doplhins came closer. Too close!

"They can't move on the sand!" Alex cried. The dophins started whistling as they splashed in the shallow water.

"They're calling for help!" cried Lucas. One dolphin moved its tail, trying to propel itself back into the water.

"Well, there's nothing we can do," said Alex. "We can't help. I don't want to stay. Let's go".

"We have to help!" shouted Lucas. "They'll die!"

He raced over to a group of people farther up the beach.

"Help!" cried Lucas. "There are dolphins stuck in the shallow water.
