The company says the vehicle, called Vision Urbanetic, will

3、 be able lo easily change bodies depending on its desired use.

7、o protect the environment.BScientists often compare coral reefs（珊瑚礁） to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color1 from algae（藻类） living inside them. When corals experience

8、stress from hot temperatures or pollution, theyhaltthe interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but theyre at risk and many eventually die, turning dark brown.Scientists around the world are looking for means to

9、 protect and maybe increase corals. One common option is to create more protected areas essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to ke

10、ep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.To keep the wild ecosystem alive, Erinn Muller, the centers director, and her team are harvesting

11、samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.

12、In The Bahamas, Ross Cunning, a research biologist at Chicagos Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didnt. We think their ab

13、ility to deal with these higher temperatures is built into their genes, says Cunning. Theres evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.4. What does the underlined w

14、ord halt in the first paragraph mean?A. End. B. Develop. C. Strengthen. D. Weaken.5. What do Muller and her team do to save corals?A. Restore the damaged reefs. B.

25、ed by a team of Swedish researchers on Friday in the journal Scientific Reports.The scientists followed 3.4 million people over the course of 12 years and found that adults who lived alone and owned a dog were 33 percent less likely to die during the study than adults who lived alone without dogs. I

26、n addition, the single adults with dogs were 36 percent less likely to die from heart disease.“Dog ownership was especiallyprominentas a protective factor in persons living alone, which is a group reported previously to be at higher risk of heart disease and death than those living in a multi-person

27、 household,” Mwenya Mubanga, a Ph.D. student at Uppsala University in Uppsala, Sweden, and the lead junior author of the study, said in a statement announcing its findings. The link between dog ownership and lower mortality（死亡率）was less pronounced in adults who lived either with family members or pa

28、rtners, but still present, according to the study. “Perhaps a dog may stand in as an important family member in the single households,” Mubanga added. “Another interesting findingwas that owners of dogs which were intended originally for hunting were most protected.”The study, which is the largest t

29、o date on the health relations of owning a dog, suggested that some of the reasons dog owners may have a lower risk of mortality and heart disease were because dog owners walk more. “These kind of epidemiological （流行病学的）studies look for associations in large populations but do not provide answers on

30、 whether and how dogs could protect their owners from heart disease,” Tove Fall, a senior author of the study and a professor at Uppsala University, said in a statement“We know that dog owners in general have a higher level of physical activity, which could be one explanation to the observed results

31、,” Fall added. “Other explanations include an increased well-being and social contacts or effects of the dog on the bacterial microbiome（微生物菌群） in the owner.” Fall added that because all participants of dog owners in Sweden or other “European populations with similar culture regarding dog ownership.”12.
