本文从以下几个角度介绍。

To know how large whales fed,the scientists running the study developed sensors thatcan deteet fish and krill as the whale eats them.These sensors,which are stuck on the whales,were used to track 321 baleen whales from seven different species in the Southern Ocean.which surrounds Antarctica.Using this technology,the scientists found the whales eat threeor more times than previously thought.This means that pre-whaling populations in the Southern Ocean alone would have eatenabout 400 million metric tons of krill per year,far more than had been assumed.It meanswhales produce a lot more of their iron-rich poop(),the fact which explains the severityof environmental damage when they were killed.As the whales feed and poop,theyredistribute the iron towards the surface of the ocean.That makes the iron available forphytoplankton(浮游植物)which can't grow without the nutrient.These in turn are eaten bykrill,which are eaten by the whales.Because the whales seem to be such a key factor in the ecosystem,reestablishing thewhale population in the Southern Ocean and in other oceans would be beneficial to the marineenvironments,said Savoca.28.What was the concern of scientists in the 1970s?A.Large whales might go extinct in the following 50 years.B.The loss of whales might result in a huge increase of their foodC.Industrial whaling might reduce the population of krill and fish.D.Animals feeding on krill might be removed from the food chain.29.What are the sensors used to do?A.Help whales to hunt for food.B.Warn whales of possible dangers.C.Know whales'food consumption.D.Compare different whale species.30.What is the significance of whales'existence according to the text?A.To ensure the proper functioning of ecosystems.B.To limit the growth of phytoplankton on the surface.C.To prevent ocean water from being seriously polluted.D.To help other sea animals produce more iron-rich poop.31.What can be the most suitable title for the text?A.A New Study Finds the Best Way to Protect WhalesB.A New Study Offers an Answer to the "Krill Paradox"C.A New Study Reveals the Damage of Industrial WhalingD.A New Study Explains Why Whale Populations Are DecliningDWhen it comes to games such as chess or Go,artificial intelligence(AI)programs have farsurpassed the best players in the world.These "superhuman"AIs are unmatched competitors,but perhaps harder than competing against humans is collaborating with them.Can the sametechnology get along with people?In a new study,researchers sought to find out how well humans could play thecooperative card game Hanabi with an advanced AI model.In single-blind experiments,participants played two series of the game:one with the Al agent as their teammate,and theother with a rule-based agent,a bot manually programmed to play in a predefined way.The results surprised the researchers.Not only were the scores no better with the Alteammate than with the rule-based agent,but humans consistently hated playing with their AIteammate.They found it to be unpredictable,unreliable,and untrustworthy,and feltnegative even when the team scored well."It really highlights the nuanced distinction between creating AI that performs objectivelywell and creating AI that is subjectively trusted or preferred,"says Ross Allen,a researcherin the Artificial Intelligence Technology Group."It may seem those things are so close thatthere's not really daylight between them,but this study showed that those are actually twoseparate problems.We need to work on disentangling those.【2022冲刺押题卷·英语（四）第5页（共8页）G-N】
