    This bear family lives in a park in Mexico. There are three baby bears in this family. They are little and naughty. Mommy bear looks after them carefully.

    One day, it was very hot. The mom bear really wanted to take a bath (洗澡), but she couldn't leave the babies there. Why? Because nobody helped her look after her children. Mommy bear thought and thought, and then she had a good idea. She put the babies on her back and took them to the lake. Hold on, baby bears!
