Previous writing.BCraig Foster, bare-chested, was diving in bitterly cold waters off the southern-most tip of Africa when he saw heran octopus hiding under a coat of shells and stones.Deeply attracted, he began following this incre
20、dibly shy creature. He kept coming back every day to the same place where he first met her, trying to stay very still in her presence. For weeks she refused him: hiding in her home, or pushing her liquid body into the nearest crack to escape. And then, after Fosters dogged persistence for 26 days, s
21、he reached out and touched him.In the documentary “My octopus Teacher”, this tender moment moves you in a way you never thought an octopus tentacle (触手) wrapped around a human hand could. The nature documentary won Best Feature at the EarthxFilm Festival 2020.“If you gain the trust of that animal ov
22、er a period of months, it will actually ignore you to a certain degree and carry on with its normal life, and allow you to step inside its secret world,” Foster says in his documentary.We see her outsmarting a shark by riding on its back, growing a new tentacle after surviving a shark attack, and fi

Over the years other animals have reached out to make contact, including dolphins, whales and even sharks. “But nothing has compared to this once-in-a-lifetime
25、 bond with the octopus,” Foster says.The octopus changed Fosters life forever.

28、do is wait until a buyer trucks through. The system works fairly well for beans and corn, but mangoesthe areas other main cropspoil (腐烂) more quickly. If the trader is late, they rot.Obadiah Kisaingu, a farmer in Masii, estimates 40% of the villages mango crop is lost to spoilage. But a simple coati
29、ng could change that. A company, SmartTech, has created a product that doubles the shelf life of fresh produce, enabling farmers like Kisaingu to access far-off, larger markets. More time for fresh produce on grocers shelves also means less food wastea $2.6 trillion problem, according to the United
30、Nations food and Agriculture Organization (FAO).James Rogers, CEO of SmartTech, who has a Ph. D in materials science, wanted to solve the problem for food much in the same way that oxide barriers preventing rust (锈) have achieved for steel. Fortunately, researchers have found when plants made the ju
31、mp from water to land hundreds of millions of years ago, they developed cutin, a barrier which is made of fatty adds that link together to form a seal around the plant, helping keep water in.The cutin was such a grand strategy that today youll still find it across the plant kingdom. Not that its exa
32、ctly the same solution across the board: An orange can last longer than a strawberry not so much because of the thickness of its skin, but because of the difference in the arrangement of those cutin molecules (分子) on the surface. SmartTechs challenge was first identifying the key components of cutin
33、. After extensive trials, Rogers and his team developed a natural and tasteless protective coating from plant materialstems, leaves and skins. The product extends the sweet spot between ripening and rot. And best of all, the treated produce doesnt require refrigeration.SmartTech traveled a long road
34、 to get here. It was six years from launch before products applied with the substance were in stores. SmartTech-treated fruits and vegetables are already in large grocery chains in Europe and the U. S. and the company recently gained regulatory approval in several less developed countries in South A
35、merica.“SmartTech has huge potential to turn poor farmers in Africa into commercial farmers,” says Rogers. “That means more money in pockets, and more food in stomachs.” But whether the company can cost-effectively reach small farmers in far-off areas still remains a challenge.27. The author mention

What can we learn about SmartTechs product?A. It is financially supported by F
37、AO.B. It is intended to replace refrigeration.C. It is designed to thicken produces skin.D. It is based on plants own defence system.29. What does James Rogers expect?A. To profit farmers.B. To earn more money.C. To produce more food.D. To expand grocery chains.30. The main purpose of the passage is
38、 to _.A. prove a theoryB. promote a productC. introduce a companyD. present a technologyDElizabeth Spelke, a cognitive (认知的) psychologist at Harvard, has spent her career testing the worlds most complex learning systemthe mind of a baby. Babies might seem like no match for artificial intelligence (A
39、I). They are terrible at labeling images, hopeless at raining text, and awful at-video games. Then again, babies can do things beyond the reach of any AI. By just a few months old, theyve begun to grasp the foundations of language, such as grammar. Theyve started to understand how to adapt to unfami
40、liar situations.Yet even experts like Spelke dont understand precisely how babiesor adults, for that matterlearn. That gap points to a puzzle at the heart of modern artificial intelligence: Were not sure what to aim for.Consider one of the most impressive examples of AI, Alpha Zero, a programme that
41、 plays board games with superhuman skill. After playing thousands of games against itself at a super speed, and learning from winning positions. Alpha Zero independently discovered several famous chess strategies and even invented new ones. It certainly seems like a machine eclipsing human cognitive
42、 abilities. But Alpha Zero needs to play millions more games than a person during practice to learn a game. Most importantly, it cannot take what it has learned from the game and apply it to another area.To some AI experts, that calls for a new approach. In a November research paper, Francois Cholle
43、t, a well-known AI engineer, argued that its misguided to measure machine intelligence just according to its skills at specific tasks. “Humans dont start out with skills: they start out with a broad ability to acquire new skills,” he says. “What a strong human chess player is demonstrating is not on
44、ly the ability to play chess, but the potential to fulfill any task of a similar difficulty.” Chollet posed a set of problems, each of which requires an AI programme to arrange colored squares on a grid (格栅) based on just a few prior examples. Its not bard for a person. But modernmachine learning pr
45、ogrammestrained on huge amounts of datacannot learn from so few examples.Josh Tenenbaum, a professor in MITs Center for Brains, Minds & Machines, works closely with Spelke and uses insights from cognitive science as inspiration for his programmes. He says much of modern AI misses the bigger picture,
46、 comparing it to a cartoon about a twodimensional world populated by simple geometrical (几何形的) people. AI programmes will need to learn in new waysfor example, by drawing causal inferences rather than simply finding patterns. “At some pointyou know, if youre intelligentyou realize maybe theres somet
47、hing else out there,” he says.31. Compared to an advanced AI programme, a baby might be better at _.A. labeling imagesB. identifying locationsC. playing gamesD. making adjustments32. What does the underlined word “eclipsing” in Paragraph 3 probably mean?A. Stimulating.B. Measuring.C. Beating.D. Limi
48、ting.33. Both Francois Chollet and Josh Tenenbaum may agree that _.A. AI is good at finding similar patternsB. AI should gain abilities with less trainingC. AI lacks the ability of generalizing a skillD. AI will match humans in cognitive ability34. Which would be the best title for this passage?A. What is exactly intelligence?B. Why is mo
