Honeybees cannot live alone. Their body structure and instincts equip them for life in a colony(群居)or community, where they have a complex social organization and the various duties are divided among the individuals according to physical fitness and age. An individual worker bee cannot reproduce itself. While it may continue to live if forcibly isolated from its mates, it fails to care for itself adequately(足够), and soon dies. Most insects have the ability to hibernate(冬眠)in winter, but the honeybee seems to have lost this. Since at low temperatures the bee will die, it must have the ability to make its own environment, so far as temperature is concerned. This makes a colony necessary to the bees in winter, so that they may collectively warm each other. Efficiency, if not necessity, demands that the work of the colony be divided, and such a division of labor tends to increase the need to maintain the colony. The physical structure of the honeybee is further suited for the defense of the entire colony rather than for its own defense. The bee’s barbed(有刺的)sting is used only once and is made more effective by the fact that it is left behind in the victim. With the loss of the sting, however, the bee dies. This kind of defensive weapon is not of service to the individual, but to the community.
According to the passage, bees differ from most other communities of insects in their need to______.
选项
A、reproduce in large numbers
B、control the temperature where they live
C、divide the work of their colonies
D、have a complex defense system
答案
B
解析
由第五、第六句可知,因蜜蜂失去了其它昆虫具有的冬眠能力,就温度而论,它必须具有制造自己的环境的能力。所以答案为B。
