The Disappearing Honeybee

Do you run away when you hear a bee buzzing?Many people do. A bee sting hurts and some people are allergic to bee venom (蜂毒) . But did you know that bees are very important to humans?Honeybees do more than just make honey. They fly around and pollinate (傳授花粉) flowers,  plants, and trees.   26   One third of America's food supply is pollinated by the honeybee.

Have you seen or heard a honeybee lately?Bees are mysteriously disappearing in many parts of the world. Most people don't know about this problem. It is called Colony Collapse Disorder (CCD) . Some North American beekeepers lost 80%of their hives (蜂巢) from 2006—2008. ___27___
