Can fish adapt?Most studies have habituated fish to lifted acidic conditions over a few days ormonths-an extremely short length of time.The animals are not given a realistic opportunity toadapt.Yet some scientists thought that fish might escape the anger of ocean acidification,in partbecause early research done in the 1980s showed that certain animals had an astonishing ability toregulate their internal chemistry to survive acidified water.But maintaining normal functions suchas avoiding danger is a different challenge.At a minimum,confusion could place yet another stressor on fish already challenged by risingwater temperatures,overfishing,etc.Further,if many ocean creatures start to behave strangely,entire food webs and ecosystems could come crashing down.Although the science is still new,theresults appear to be lining up:ocean acidification is messing with fish's minds.27.What does the underlined word "treacherous"in Paragraph 1 probably mean?A.Risky.B.Hurried.C.Mysterious.D.Helpless.28.What can we learn about the fish in the acidic water?A.They lost their senses to chemical signals.B.They were less likely to respond to threats.C.Their behavior in the lab disappeared in the wild.D.They tended to seek the protection from their home.29.What can be inferred from the passage?A.The author's study confirms previous findings.B.Fish's adaptation to acidic water is a matter of time.C.Different fishes behave differently to acidity change.D.The chances of restoring fish's minds are yet to be seen.30.Which of the following would be the best title for the passage?A.What Do Different Stressors Do to Ocean Creatures?B.What Does Ocean Acidity Mean to Ocean Creatures?C.How Does Ocean Acidification Destroy the Ecosystem?D.How Do Ocean Creatures Adapt to Ocean Acidification?DA snake-robot designer,a technologist,an extradimensional physicist and a journalist walkinto a room.The journalist turns to the crowd and asks:Should we build houses on the ocean?Like a think-tank panel,members of the team dream up far-out answers to the crucial problem,such as self-driving housing units that could park on top of one another in the coastal city center.The setting is X,the enterprise which considers more than 100 ideas each year,in areasranging from clean energy to artificial intelligence.Although only a tiny percentage become"projects"with far-reaching creativity,these projects exist,ultimately,to chang the world,likeWaymo,the biggest self-driving-car company.高三英语第6页（共10页）
