Researchers at Ben-Gurion University of the Negev in Be’er Sheva, Israel, taught six goldfish to drive a motorised water tank. Whenever the fish swam near one of the tank’s walls, facing outwards, the vehicle moved in that direction. That these fish could move on land gave the researchers the conclusion that fishes’ understanding of space and direction is not limited to their natural environment. The goldfish were educated on how to drive during about a dozen 30-minute sessions. The researchers trained each fish to drive from the centre of a small room to a pink board on one wall by giving the fish a treat whenever it reached the wall. The fish was equipped with a camera that continually tracked the fish driver’s position inside the tank. 刷阅读理解 22 In the experiment, during their first sessions, the fish averaged about 2.5 successful trips to the target. During their final sessions, they averaged about 17.5 successful trips. Finally, the animals also took faster, more direct routes to their goal. In further experiments, the goldfish were still able to reach the pink board when starting from random positions around the room, rather than the centre. This finding confirmed that the fish had not merely memorised a set of movements to reach their reward, but were planning routes towards their prize each time. When the researchers tried to hoax the goldfish by placing boards of different colours on the other walls or moving the pink board to the other side of the room, the fish were not fooled, and navigated to the pink board. Behavioural neuroscientist Kelly Lambert was “not completely surprised” by the driving abilities of the fish. In her research at the University of Richmond in Virginia, Lambert has taught rats to drive toy cars. “But teaching goldfish to navigate such unfamiliar land takes animal driving experiments to the next level,” Lambert said. “I love the fish-out-of-water idea. When it comes to testing the limits of animal navigation, it’s important to diversify and expand our tasks and our species.” 刷阅读理解 23 【语篇导读】本文是一篇说明文。文章主要介绍了一项新的实验表明，鱼实际上是很好的司机，它们的空间感和方向感不受环境的限制。文章主要介绍了研究开展的过程。 1.How did the researchers train the fish to drive?( ) A A.By offering rewards for the fish’s successful trips. B.By making use of the fish’s sense of colour. C.By setting examples to the fish beforehand. D.By playing training videos to the fish. 解析 细节理解题。根据第三段中的The researchers trained each fish to drive from the centre of a small room to a pink board on one wall by giving the fish a treat whenever it reached the wall.可知，研究人员通过对成功到达指定位置的鱼提供奖励，来训练这些鱼“驾驶”。故选A项。 刷阅读理解 24 2.How does Paragraph 4 mainly develop?( ) B A.By providing examples. B.By making comparisons. C.By analysing reasons. D.By drawing conclusions. 解析 推理判断题。根据第四段内容可知，该段介绍了不同实验阶段的结果，并将结果进行对比，故第四段的写作手法为对比。故选B项。 刷阅读理解 25 3.What does the underlined word “hoax” in Paragraph 5 mean?( ) D A.Treat. B.Amuse. C.Catch. D.Trick. 解析 词义猜测题。根据画线词后文the fish were not fooled, and navigated to the pink board 可知，当研究人员试图通过在其他墙壁上放置不同颜色的木板或将粉色木板移到房间的另一侧来欺骗金鱼时，金鱼并没有上当，而是开向了粉色木板，故画线词含义为“欺骗”。故选D项。 刷阅读理解 26 4.What does the text mainly talk about?( ) C A.Fishes are being studied. B.Fishes are smart animals. C.Fishes are good drivers. D.Fishes are popular pets. 解析 主旨大意题。根据第一段It might seem like a fish doesn’t need a car but fishes actually make pretty good drivers, according to a new experiment.并结合文章内容可知，本文主要介绍了一项新的研究，说明了鱼具有很好的方向感和空间感，且不受环境的限制，并介绍了研究开展的过程。由此可知，C项能够概括本文的主旨。故选C项。 刷阅读理解 27 B [辽宁重点高中沈阳市郊联体2023高二期中] The climate change in California has caused terrible damage to California’s marine ecosystems. Untold billions of sea stars, or starfish, from at least 20 species disappeared from the entire Pacific coast because of the marine heatwaves. In the absence of sunflower sea stars, a major predator of sea urchins（海胆）, the urchin population exploded. They laid waste to kelp（巨藻）forests already weakened by high ocean temperature. However, Central California’s kelp ecosystems have done somewhat better than those in Northern California. A new study led by Joshua Smith, an ecologist at the University of California, examines the role the sea otter（海獭）—a natural predator of urchins—plays in preserving existing kelp forests in the Monterey Bay. 刷阅读理解 28 The research project spanned three years, during which intensive underwater surveys produced some very interesting data about sea otters’ behaviour. Sea otters have very high metabolism（新陈代谢）that keeps them warm in icy waters and which also makes them greedy consumers of shellfish, urchins, and fish—sea otters can eat 25 percent of their body weight in food in a day. At the observed sites, as the urchin population grew, the otter’s diet shifted to becoming more heavily dependent on urchins. In fact, the otters were eating three times as many urchins as they had been before 2014. As a result, they provided crucial protection from urchins to the kelp forests. The fact that otters were able to contribute to the health of the surviving kelp forests by keeping the urchin population in check provides Smith with hope for the continued survival of kelp forests. “The important thing is that the urchins are ultimately reduced,” he says. “The sea otters have maintained patches of kelp forests that can then help refill the barren areas to enhance the recovery of forests.” 刷阅读理解 29 【语篇导读】本文是一篇说明文。文章介绍了加利福尼亚州气候变化造成海胆泛滥，从而影响到当地的巨藻林，研究发现海獭捕食海胆对巨藻林有一定的保护作用。 1.What influence does climate change have on California’s marine ecosystems?( ) D A.A greater diversity of marine species. B.The disappearance of urchins. C.An explosive growth of sea stars. D.The weakening of kelp forests. 解析 细节理解题。根据第一段中的They laid waste to kelp forests already weakened by high ocean temperature.可知，气候变化引起海水温度变高，海胆数量激增，进而影响到了巨藻林。故选D项。 刷阅读理解 30 2.What is the study led by Joshua Smith about?( ) C A.Urchins’ response to ocean warming. B.The reproduction of marine animals. C.Sea otters’ role in protecting kelp forests. D.The current condition of marine ecosystems. 解析 细节理解题。根据第二段中的examines the role the sea otter—a natural predator of urchins—plays in preserving existing kelp forests in the Monterey Bay 可知，该研究主要是调查海獭在保护现存巨藻林方面所起的作用。故选C项。 刷阅读理解 31 3.What is a direct result of the shift in sea otters’ diet?( ) C A.The sea otters are more likely to stay warm. B.The shellfish population has exploded. C.Sea urchins’ threat to kelp forests is relieved. D.The kelp forests have made a full recovery. 解析 细节理解题。根据第三段中的As a result, they provided crucial protection from urchins to the kelp forests.可知，大量的海胆被海獭捕食，海胆对巨藻林的威胁得到了缓解。故选C项。 刷阅读理解 32 4.Which of the following is a suitable title for the text?( ) A A.Sea Otters Rescue Kelp Forests B.Marine Species in Danger C.Sea Urchins Are Destroying Kelp Forests D.Sea Otters Increase Kelp Forests’ Carbon Storage 解析 主旨大意题。根据第二段中的A new study led by Joshua Smith, an ecologist at the University of California, examines the role the sea otter—a natural predator of urchins—plays in preserving existing kelp forests in the Monterey Bay.可知，本文主要介绍海獭捕食海胆在保护现存的巨藻林方面起到的作用。故A项最适合作为本文的标题。 刷阅读理解 33 核心词汇 1.intensive adj.密集的；十分细致的 2.crucial adj.至关重要的 3.ultimately adv.最终；根本上 4.enhance vt.增强；提高 构词法 eco- prefix 与环境相关的，生态（的） ecosystem n.生态系统 刷阅读理解 34 [河北保定部分高中2024高二开学考] My 5-year-old daughter Kai walked around a bus stop, picking up candy wrappers and plastic bottles and throwing them in the waste bin.
