4、ists chose the area because it is within a natural migration (迁徙)path for some animals.The 90 bridge is part of a growing number of wildlife crossings across the United States.Some are fences, some are overland bridges, and some are underpasses.They all aim to keep drivers and animals away from each

17、oneybees and ants have similar roles within the colony, both have communication systems, and both have the capacity for learning.Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source.For example, when worker ants find a promising source, they let
18、 the rest of the colony know how to find it by leaving a trail of pheromones on the way back to the colony.The other ants pick up the message using their sense of smell.Bees, on the other hand, use movement to communicate with each other.Worker bees send messages to each other by means of a “dance”D
19、ifferent speeds and movements send different messages.For example, when worker bees called the scouts go out to find a new home for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is.The faster the scouts dance, the bet
20、ter the new location is.Honeybees and ants are both capable of learning.One Chinese study found that bees can be trained to learn and remember a route to a food source.The researchers also found that bees can be taught to recognize hidden objects and use the concepts of “sameness” and “difference” t

22、 how to avoid obstacles.As we can see, the social behaviour of honeybees and ants is quite similar.Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals.Unintelligent as they may be as individuals, as groups they often show amaz
