Ocean noise has been increasing over the years， and an international research team recently reported in Global Change Biology that when the water got too noisy， whales spent more time looking for food but caught fewer fish.The study tracked every move and sound that individual killer whales made， as well as the sound reaching those whales.This is the first time scientists have linked noise reaching a given killer whale to their foraging (觅食) success， says lead author Jennifer Tennessen. The noise problem is one that Tennessen views as chronic， yet possibly more straightforward to fix than declining fish populations or pollution—ships could simply slow down to make less noise.Fortunately， with the guidance of both governmental and nongovernmental groups， some ship operators are slowing down. The Vancouver Fraser Port Authority in Canada reported in 2023 that 87 percent of ships slowed or moved over for southern resident whales in critical habitat， which led to a decrease of 4.2 decibels (分贝) compared to 2019， before slowdowns began.Washington ports and other local authorities join in a program of voluntary slowdowns in Washington waters called Quiet Sound， which offers information on killer whale locations.About 70 percent of ships follow Quiet Sound’s guidelines and voluntarily slow down in killer whale critical habitat. The talk about innovations in propeller (螺旋桨) technology is also positive.A propeller， for example， is based on a design for a quieter drone propeller.If claims of a more efficient and quieter boat propeller are true， that’s good news for both reducing fuel use and quieting traffic. Tennessen says increasing ship noise is a problem in oceans around the world.“We’re finally able to measure the impacts that it’s having on wildlife，” she says， “and we’re finding that the impacts are numerous.” 　　【语篇解读】　本文是一篇说明文。文章主要介绍了越来越多的海洋噪音污染问题给鲸鱼的捕猎带来了困扰，为此，各方从多个角度投入力量改变这一现状。 1.Why does the author mention a salmon’s invisible cloak？ A.To introduce the feature of sound waves. B.To describe the environment in whales’ hunting. C.To emphasize the invisibility of salmons’ cloak. D.To demonstrate the characteristic of whales’ hunting. √ 推理判断题。根据第一段中的“But a common feature of modern ocean life may be like a salmon’s invisible cloak (隐形斗篷)， making the whales’ favorite meal harder to find.What is to blame？ Boat traffic noise.”可知，这里使用鲑鱼的隐形斗篷作为一个比喻，描述了船只交通噪音如何使得鲸鱼更难找到它们的食物，就像给鲑鱼穿上了一件隐形斗篷一样，由此可知，文中提到鲑鱼的隐形斗篷是为了表明鲸鱼捕食困难的境况。故 选B。 2.What do the statistics indicate in Paragraph 4？ A.Noise reduction is ineffective. B.Ship operators ignore guidelines. C.Quiet Sound prioritizes noise monitoring. D.Voluntary slowdowns lead to noise reduction. √ 推理判断题。根据第四段中的“The Vancouver Fraser Port ... before slowdowns began.”可知，大多数船只遵循指导原则并自愿在关键栖息地减速，从而实现了噪音水平的有效降低，由此可知，第四段中的数据表明了自愿减速导致噪音减少。故选D。 3.What is the significance of propeller technology innovations？ A.To address noise issues. B.To reduce fuel efficiency. C.To follow Quiet Sound’s guidelines. D.To help measure influences on wildlife. √ 推理判断题。根据倒数第二段中的“A propeller， for example， is based on a design for a quieter drone propeller.If claims of a more efficient and quieter boat propeller are true， that’s good news for both reducing fuel use and quieting traffic.”可知，螺旋桨技术的创新旨在制造更加安静和高效的船用螺旋桨，有助于解决噪音问题，由此可知，螺旋桨技术创新的意义是解决噪音问题。故选A。 4.Which of the following is the best title for the text？ A.Ships Slow Down for Whales B.Boat Noise Clouds Whale Foraging C.Killer Whales Battle Noise Pollution D.Technology Innovations Silence Propellers √ 标题归纳题。根据第一段中的“But a common feature of modern ocean life may be like a salmon’s invisible cloak (隐形斗篷)， making the whales’ favorite meal harder to find.What is to blame？ Boat traffic noise.”可知，噪音污染像鲑鱼的隐形斗篷一样，使得虎鲸难以捕捉到它们的主要食物来源，引出下文介绍的通过船只减速和其他技术手段来减轻这种影响的努力，由此可知，本文主要讲述了船只噪音污染问题给鲸鱼的捕猎带来的困扰以及解决这一问题的方法和技术进步。故选B。 B (2026·安徽六校高三联考) 　　Facing intense competition for foods， sea otters (海獭) survive with the help of tools—like rocks and even glass bottles—that let them break open tougher prey (猎物) that they wouldn’t otherwise be able to eat. That’s according to a new study of sea otters in Monterey Bay， California， which took a look at the tool use of individual otters.The findings reveal how this may increase their chances of survival in an uncertain world.Sea otters spend their days looking around for food in kelp (海藻) forests.They dive to the bottom to grab tasty food， plus sometimes rocks that they plan to use as tools. They bring these to the surface and float on their backs as they get to work on opening and eating their snacks.“Their preferred food is urchins (海胆)，” says biologist Chris Law， who notes that urchins are relatively easy for otters to break apart.But there are areas over-abundance of urchins， where urchins have eaten all the kelp.Since the kelp is gone， however， these urchins no longer have a good food supply and provide little nutritional value for otters.That’s a matter of life-and-death to otters， so they aren’t interested in consuming them. “So that means otters have to eat alternative foods，” says Law.“Many of them are those super hard prey items that really require some kind of external force to break into.” Law and some co-workers analyzed data on 196 otters in California.It turns out that frequent tool users were able to eat harder and larger prey.This was particularly important for female otters， since they’re smaller than males and aren’t able to bite down with as much force. “They typically wouldn’t be able to break into harder prey，” says Law.“But they use tools more than males， so they’re able to gain access to these novel sources of food items.” Besides， using tools protected the otters’ teeth.The researchers found that tool users had less dental damage from biting hard food items. 　　【语篇解读】　本文是一篇说明文。文章介绍了海獭在食物竞争中借工具生存及相关生存策略。 5.What can we infer about kelp and urchins？ A.Urchins survive kelp. B.Urchins destroy kelp forests. C.Kelp and urchins coexist. D.Kelp restricts urchins’ growth. √ 推理判断题。根据第二段“But there are areas over-abundance of urchins， where urchins have eaten all the kelp.”可知，海胆会破坏海藻森林。故选B。 6.Why are urchins abandoned by sea otters？ A.Urchins offer little nutrition. B.Otters find novel food items. C.Urchins are hard to break apart. D.Otters are tired of eating urchins. √ 细节理解题。根据第二段“Since the kelp is gone， however， these urchins no longer have a good food supply and provide little nutritional value for otters.That’s a matter of life-and-death to otters， so they aren’t interested in consuming them.”可知，海獭之所以会抛弃海胆，是因为海胆提供的营养很少。故选A。 7.What can we know about male otters？ A.They prefer to consume soft food.
