小兔子贝拉关心妈妈，自己煮汤给妈妈喝，多可爱呀。听了故事，小朋友还可以知道为什么汤会越煮越少。妈妈们可以给孩子做个小实验，看看一锅水是不是越煮越少了，再仔细给他们讲讲这是为什么。 Little bunny Bella cares for her mother and cooks soup for her to drink, which is so adorable. After listening to the story, children can also understand why the soup diminishes as it cooks. Mothers can conduct a little experiment with their children to see if a pot of water really decreases as it boils, and then explain to them carefully why this happens.
