Have you ever seen a honeybee in the winter? Most people in temperate（温和的） climates （probable） have not. When temperatures in the winter drop below 10℃, honeybees, without blankets, fires, adjustable thermostats （恒温器）, return to （they）hives, forming a winter cluster for warmth —— sort of like a giant three-month slumber party in the winter.
The fate of the hive （depend） on how sufficiently the winter population has prepared for the cold. （keep） warm and survive, the honeybee swarm（蜂群） must have a strong population of winter-ready bees, plentiful stores of honey to eat, and a secure hive. A successful winter cluster is made up of a generation of bees, have a longer lifespan（寿命） to last the whole winter.
The social world of honeybees is normally divided into three（variety）: workers, drones, and queens. , the male drones die off in the winter, （leave） only the female workers and the queen. To maintain a survivable heat, the all-female swarm of bees crowds together tightly to form the winter cluster, with the queen at the warmest place, the （centre） section of the group, and the workers shaking around.
