Black bears scare tourists - level 1
Yellowstone National Park is a national park in the USA. The black bear is the park’s symbol.
An incident happens in the park. A group of bears chase tourists. One of the bears is a mother. The other bears are her cubs. Bear mothers protect their cubs. If the cubs are in danger, they can attack.
The tourists are scared. They get inside their cars. Others take photographs of the bears.
Difficult words: national park (a big area where animals live freely), chase (to get closer and closer to somebody), cub (a young bear).
