17、lose interspecies bond that exists between humans and dogs may extend 27000 or even 40000 years back. That“s a 1 jump from 11000 to 16000 years ago, when dogs were 2 thought to have split from their wolf ancestors. Led by Harvard research fellow Pontus Skoglun, the authors of the study 3 DNA belongi

18、ng to a 35000-year-old Siberian wolf specimen. Their genomic analysis led them to 4 that the wolf was part of a population “that diverged from the common ancestor of present-day wolves and dogs very close in time to the 5 of the domestic dog lineage,“ according to an abstract. That means domesticate

19、d dogs may have been hanging out with humans during that same era, more than 20000 years ago. The 6 for this finding was the discovery of the ancient bone, the abstract notes: The researchers made these 7 based on a small piece of bone picked up during an expedition to the Taimyr Peninsula in Siberi

20、a. Initially, they didn“t realize the bone fragment came from a wolf at all; this was only 8 using a genetic test back in the laboratory. But wolves are common on the Taimyr Peninsula, and the bone could have easily 9 to a modern-day wolf. On a hunch, the researchers decided to radiocarbon date the

21、bone anyway. It was only then that they realized what they had: a 35000-year-old bone from an 10 Taimyr wolf.

22、：35.50）八、Section B(总题数：1，分数：71.00)Why You Shouldn“t Freak Out About Swarming Honeybeesand How to Save Bees From Those Who DoA. 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 you“re a beekeeper, the

23、changing seasons may have an extra significance: It“s the start of honeybee swarm season. B. To many, a swarm of honeybeeswhich can number well above 10000 bees and take the form of a living, buzzing, basketball-sized clump of insectsis the stuff of nightmares. But both scientists and beekeepers (wh

24、o manage hives of honeybees either for fun or to sell honey commercially) encourage citizens not to kill or attack the bees 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 t

25、he beekeeperit can help save struggling bees, too. C. And that“s critical: Concern over protecting honeybees has never been 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 th

26、eir hives. The US Department of Agriculture estimates that honeybee populations are less than half what they were in the 1940s. D. Most scientists believe the honeybee“s plight has been caused by a complex set of factors, including negative effects from pesticides, various diseases and parasites, an

27、d habitat degradation. One of the most recent honeybee studies found that beekeepers lost about 40 percent of their commercial 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

28、 could have a major impact on human food supplies. E. Policy-makers are taking the problem seriously. Last week, the Obama administration 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 restri

29、ctions on certain pesticides and restoring land for use by pollinators. Still, honeybees are not protected under the Endangered 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, whi

30、ch tend to appear more menacing than they actually are. F. Swarming is a particular behavior that honeybees exhibit in the late spring or early summer as a way of propagating (繁殖) the species, says Andrew Cot, a New York-based beekeeper and founder of the New York City Beekeepers Association. When a

31、 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 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 they“re looking for a suitable new home, the

32、se swarms sometimes make brief stopovers on tree branches, walls, road signs or other objects. Their appearancea dripping ball of stinging insectscan be menacing, but neurobiologist and bee expert Thomas Seeley says honeybees are at their safest when exhibiting swarming behavior. H. “The reality is

33、that a swarm of bees is not defensive,“ says Seeley, a professor of neurobiology and behavior at Cornell University, where he specializes 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

34、 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 bees 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 it“s not,“ he says. “It“s just a

35、temporary assemblage.“ But some businesses or homeowners might get antsy (坐立不安的) about having a huge blob of bees hanging around, particularly 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,

36、 to come and safely remove the swarm, rather than attempting to spray it with insecticide or hire an exterminator. J. Beekeeper Toni Burnham, founder of the D.C. Beekeepers Alliance and president of the Maryland State Beekeepers Association, Inc., says some exterminators will refuse to destroy honey

37、bees. But even in these cases, some citizens may take matters into their own hands by spraying the swarm with insecticide or other chemicals. K. Seeley says it would be hard to put a number on the population-level effects of destroying honeybee swarms. “I don“t know if it“s contributing much to the

38、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 thing is there“s really no need to destroy them.“ L. And even swarms that are left alone by humans are homeless and vulnerable to environmental disturbances. M

39、any don“t make it to their next hive, says Burnham. But she adds that allowing beekeepers to collect swarms can have other benefits besides just saving the bees. M. Burnham says collecting swarms can help beekeepers by bolstering (改善) the genetic pool on their bee farms. A swarm that“s found in an u

40、rban setting, where there aren“t too many bee farms around, likely came from a feral (野生的) colonya colony that isn“t being managed by beekeepers and essentially 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

41、. N. “We“re in a day and age where we“re trying to find bees that know how to cope with pests and disease, that know how to cope with profound changes in climate. 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

42、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 advantage for beekeepers. “If you“re not in a suburban area or something like that, chances are that the swarm is coming out of a wild colony,“ he

43、says. “They“ve been tested. They“ve had to be living somewhere on their own.“（分数：71.00）(1).Beekeepers have lost many honeybees, which may finally result in the decline of human food supplies.（分数：7.10）(2).Capturing the swarm alive not only benefits beekeepers but also the decreasing bees.（分数：7.10）(3)

You“ve spent the last several hours on your phone, scrolling through your Facebook news feed, refreshing Twitter and watching YouTube videos. A smartphone mi

Data from a recent study conducted by researchers at Northwestern University“s Feinberg School of Medicine found that the scenario described abovehigh volume of phone use and a static (静止的) geographic locationc

49、ould be linked to depression. The study, published in The Journal of Medical Internet Research , also found that depressed people, on average, spend more time on the phone than non-depressed people. “People are likely, when on their phones, to avoid thinking about things that are troubling, painful feelings or difficult relationships,“ said David Mohr, one of the study“s senior authors and a professor of behavioral psychology at Northwestern, in a statement. “It“s an avoidance behavior we
