Many dolphins swam fast - level 1
Many dolphins swam near the Japanese coast. They wanted to swim away from killer whales. People saw the dolphins and they filmed them.
The dolphins had to be fast. If they were not fast, the killer whales would eat them. Killer whales live in groups like dolphins. You can see killer whales in cold seas and in warm waters too.
Interesting words: coast (land near the sea), killer whale (big black and white sea animal).
You can read the original story and watch the video in the Level 3 section.
