In F

15、rance, newly built commercial rooftops must have either greenery or solar panels, according to a recent law. The logic is obvious: Green roofs can reduce the retention(滞留)of 1in urban areas, help to cool down buildings and thereby lower their energy use, and even pull some carbon dioxide from the ai

21、 Who Do A)For many people, the late-spring onset of warm weather conjures up images of barbecues, beach trips and long afternoons spent out in the sun. But if youre a beekeeper, the changing seasons may have an extra significance: Its the start of honeybee swarm season. B)To many, a swarm of honeybe

22、eswhich can number well above 10 000 bees and take the form of a living, buzzing, basketball-sized clump of insectsis the stuff of nightmares. But both scientists and beekeepers(who manage hives of honeybees either for fun or to sell honey commercially)encourage citizens not to kill or attack the be

23、es if they happen upon a swarm. In fact, as the nation continues to experience widespread honeybee declines, allowing a beekeeper to capture the swarm alive is not only good for the beekeeperit can help save struggling bees, too. C)And thats critical: Concern over protecting honeybees has never been

24、 higher. Honeybees have been declining for several decades, largely thanks to a mysterious phenomenon known as colony collapse disorder, which causes bees to suddenly abandon their hives. The US Department of Agriculture estimates that honeybee populations are less than half what they were in the 19

25、40s. D)Most scientists believe the honeybees plight has been caused by a complex set of factors, including negative effects from pesticides, various diseases and parasites, and habitat degradation. One of the most recent honeybee studies found that beekeepers lost about 40 percent of their commercia

26、l colonies in the past yeara worrisome statistic because honeybees play a crucial role in pollinating(授粉)crops. In fact, many experts are afraid that their continued decline could have a major impact on human food supplies. E)Policy-makers are taking the problem seriously. Last week, the Obama admin

27、istration released its National Strategy to Promote the Health of Honeybees and Other Pollinators, which aims to put honeybees on the upturn by reviewing and placing restrictions on certain pesticides and restoring land for use by pollinators. Still, honeybees are not protected under the Endangered

28、Species Act, and there are no federal laws to prohibit people from killing them, although state-level regulations may vary. This can be unfortunate for honeybee swarms, which tend to appear more menacing than they actually are. F)Swarming is a particular behavior that honeybees exhibit in the late s

29、pring or early summer as a way of propagating(繁殖)the species, says Andrew Cote, a New York-based beekeeper and founder of the New York City Beekeepers Association. When a colony gets big enough, it splits in two and the queen bee flies off, usually taking a third to a half of the colony with her, in

30、 search of a new home.(Back at the home base, a new queen will take her place and continue on with the old colony.) G)While theyre looking for a suitable new home, these swarms sometimes make brief stopovers on tree branches, walls, road signs or other objects. Their appearancea dripping ball of sti

31、nging insectscan be menacing, but neurobiologist and bee expert Thomas Seeley says honeybees are at their safest when exhibiting swarming behavior. H)“The reality is that a swarm of bees is not defensive,“ says Seeley, a professor of neurobiology and behavior at Cornell University, where he speciali

32、zes in the behavior and social life of honeybees. Swarming bees are still en route to a new home, meaning they have no nest and no stores of honey to defend, and they tend to be at their most docile(温顺的). I)Swarms rarely stay in one place for more than a day or so, says Seeley, so chances are the be

33、es will take off on their own if left alone. “A lot of people think that a cluster of bees is a bunch of bees building a nest, and its not,“ he says. “Its just a temporary assemblage.“ But some businesses or homeowners might get antsy(坐立不安的)about having a huge blob of bees hanging around, particular

34、ly if there are children in the area. In these cases, experts encourage citizens to call a local beekeeper, a person who has experience managing honeybee hives, to come and safely remove the swarm, rather than attempting to spray it with insecticide or hire an exterminator. J)Beekeeper Toni Burnham,

35、 founder of the D. C. Beekeepers Alliance and president of the Maryland State Beekeepers Association, Inc., says some exterminators will refuse to destroy honeybees. But even in these cases, some citizens may take matters into their own hands by spraying the swarm with insecticide or other chemicals

36、. K)Seeley says it would be hard to put a number on the population-level effects of destroying honeybee swarms. “ I dont know if its contributing much to the pressure on the population of honeybee colonies, but every time one is killed it does have some effect for sure,“ he says. “I guess the main t

37、hing is theres really no need to destroy them.“ L)And even swarms that are left alone by humans are homeless and vulnerable to environmental disturbances. Many dont make it to their next hive, says Burnham. But she adds that allowing beekeepers to collect swarms can have other benefits besides just

38、saving the bees. M)Burnham says collecting swarms can help beekeepers by bolstering(改善)the genetic pool on their bee farms. A swarm thats found in an urban setting, where there arent too many bee farms around, likely came from a feral(野生的)colonya colony that isnt being managed by beekeepers and esse

39、ntially lives in the wild. In order to survive long enough to produce a swarm in the first place, a feral bee colony must be pretty hardy, she says. N)“Were in a day and age where were trying to find bees that know how to cope with pests and disease, that know how to cope with profound changes in cl

40、imate. The genes really, really matter,“ Burnham says. “When you have a swarm, you have bees of an unknown background. One thing you do know is that they came from a strong colony, a colony that had existed for a long time.“ O)Seeley, the neurobiologist, agrees that collecting swarms can be an advan

41、tage for beekeepers. “If youre not in a suburban area or something like that, chances are that the swarm is coming out of a wild colony,“ he says. “Theyve been tested. Theyve had to be living somewhere on their own.“（分数：20.00）(1).Beekeepers have lost many honeybees, which may finally result in the d
