　　托福阅读经典加试题Bees

　　Flowers provide food for bees. The bees collect tiny grains of pollen and a sweet liquid called nectar from the blossoms they visit. They make honey from the nectar, and use both honey and pollen as food.

　　During their food-gathering flights, bees spread pollen from one flower to another, thus pollinating (fertilizing) the plants they visit. This enables the plants to reproduce.

　　The honey bee colony

　　A typical honey bee colony is made up of one queen, tens of thousands of workers, and a few hundred drones雄峰.

　　Honey bees live in hives. The hive is a storage space, such as a hollow空的 tree or a box, which contains a honeycomb蜂窝. The honeycomb is a mass of six-sided compartments隔间 called cells.

　　Worker bees build the honeycomb of wax produced by their bodies. The wax oozes渗出 through small pores (holes) in the body and forms tiny white flakes on the outside of the abdomen.

　　They also collect a sticky substance bee glue, from certain kinds of trees.

　　The body of the honey bee

　　A bee has five eyes-three small ones that form a triangle on top of its head, and a large compound eye on each side of its head.

　　Honey bees were the first insects known to be able to distinguish colors. Bees have three kinds of color-sensitive cells in their eyes. These visual cells are especially sensitive to blue, yellow, and ultraviolet rays, which humans cannot see.

　　The sting of a worker bee is straight, with barbs (hooks) on it. When the bee thrusts the sting into flesh, the barbs hold tight, and the stinger蛰针 pulls out of the bee's body.
