He was wearing only his swimming glasses, cap and Speedos! [综合能力提升练] 课后巩固 多维提能 Pugh is an advocate for ocean protection, working to protect ocean ecosystems with their great diversity of marine life. When asked why he doesn't wear a wetsuit, Pugh says, “I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I'm asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message.” 课后巩固 多维提能 It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1.6 degrees Celsius. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal. 课后巩固 多维提能 Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim. This is not the first time that Pugh has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica's Ross Sea as part of his successful campaign to help set up a marine reserve there. 课后巩固 多维提能 【解题导语】　本文是一篇记叙文。文章讲述了刘易斯·戈登·皮尤为了呼吁人们保护海洋，在南极洲冰冷的水域不穿潜水衣游泳的事迹。 课后巩固 多维提能 √ 1．Why did Lewis Gordon Pugh swim without a wetsuit? A．To swim faster. B．To show his bravery. C．To build up his body. D．To have overnight fame. 解析：推理判断题。根据第二段中的“If I'm asking them to be courageous...send the right message.”可推知，皮尤不穿潜水衣游泳是为了表现出他的勇敢。 4 5 6 7 8 1 2 3 课后巩固 多维提能 9 10 12 11 √ 2．What does the underlined word “it” in paragraph 3 refer to?

D．The water temperature. 解析：代词指代题。根据第三段中的“He says that his body...before it starts shutting down.”可知，他的身体在冰冷的水域中只能忍受大约二十分钟，然后就会开始出现身体机能衰竭的情况，所以it指代的是his body。 4 5 6 7 8 2 3 1 课后巩固 多维提能 9 10 12 11 √ 3．What's Pugh's advice about swimming in freezing waters? A．One should be ready to take up challenges. B．One should be expert at swimming. C．One must be fully prepared.

They hunt in schools of up to 40 individuals and are famous for their group attack on sea creatures. But orcas seldom attack humans. 课后巩固 多维提能 However, since 2020, groups of orcas have struck about 700 boats off the coasts of Spain, Portugal, France and Morocco. They have damaged(损坏) at least seven boats. Experts now believe what the orcas did is the result of bored teenage orcas having fun. After observing fifteen young orcas, a research team, led by Alex Zerbini, found that the orcas approached the boats slowly. Once close, they appeared to simply want to nudge their noses or heads against the rudder (船舵). Given that these young orcas measure between 2.7 and 4.2 meters in length, just a gentle touch was enough to damage the rudders and even the boats. “As they play with the rudder, they don't understand that they can damage the rudder and will affect human beings. It's more playful than purposeful，” one researcher said. 课后巩固 多维提能 The researchers thought the teenage orcas' boredom results from the increase in the population of their primary food source—the bluefin tuna. With plenty of food, they have a lot more time on their hands. They guessed the action may have been started by a curious individual attracted to the moving boat and may have inspired the others to do the same. Zerbini and his team give some suggestions about being far away from orcas when possible. While people are in the areas where orcas often appear, try to reduce the speed of the boats. Making banging sounds around the boat may keep the whales away. They also suggest boat owners replace the smooth rudder surface with special materials. This will make the boats less fun to “play” with. 课后巩固 多维提能 “We don't want to see more boats being damaged, and we don't want to see people in trouble，” Zerbini said. “But we also don't want to see orcas and other animals being hurt. We have to remember that this is their home, and we're in the way.” 【解题导语】　本文是一篇说明文。文章介绍了西班牙、葡萄牙、法国和摩洛哥海岸附近发生的一系列虎鲸撞击船只的事件。 课后巩固 多维提能 √ 5．Why do orcas strike the boats according to the research? A．To search for food. B．To seek pleasure. C.To try to communicate. D．To practice hunting skills. 解析：细节理解题。根据第二段中的“Experts now believe...bored teenage orcas having fun.”和第三段中的“It's more playful than purposeful”可知，虎鲸袭击船只是为了寻求快乐。 4 5 6 7 8 2 3 1 课后巩固 多维提能 9 10 12 11 √ 6．What does paragraph 5 mainly tell us? A．How to find orcas' tracks. B．How to draw orcas to the rudder. C．How to tell the sounds from orcas. D．How to avoid encounters with orcas. 解析：段落大意题。根据第五段中泽尔比尼和他的团队给出了一些关于尽可能远离虎鲸的建议，如：尽量减速、制造声响、更换船舵材料等可知，第五段主要介绍如何避免遭遇虎鲸。 4 5 6 7 8 2 3 1 课后巩固 多维提能 9 10 12 11 √ 7．What do we know from Zerbini's words? A．We should live in peace with animals. B．We should build more high-quality boats. C．People face challenges in developing fisheries. D．People have perfected creatures' living environment. 解析：推理判断题。根据最后一段中的“But we also don't want to see...we're in the way.”可推知，我们应该与动物和平相处。 4 5 6 7 8 2 3 1 课后巩固 多维提能 9 10 12 11 √ 8．What aspect of orcas does the passage focus on? A．Their unusual behavior. B．Their feeding habit. C．Their high intelligence. D．Their quick reaction. 解析：主旨大意题。第一段提到虎鲸通常很少攻击人类；第二段介绍自 2020 年起虎鲸频繁撞击西班牙、葡萄牙、法国和摩洛哥沿海约700艘船只；后文围绕这一不寻常行为展开研究并分析，包括行为原因及应对措施。本文关注的重点是虎鲸的不寻常行为。 4 5 6 7 8 2 3 1 课后巩固 多维提能 9 10 12 11 C (2026·日照高一期中)Garvey-Darda is a wildlife biologist for the United States Forest Service. She wants to protect her beloved pikas and other creatures from a common threat: vehicles. The Federal Highway Administration says more than a million roadway accidents involving animals happen each year in the U．S. These collisions (碰撞) hurt wildlife and people. 课后巩固 多维提能 One solution to this problem? Wildlife crossings. In the U．S. and around the world, bridges and underpasses are being built to help animals safely cross roads. Banff National Park, in Alberta, Canada, is home to some of the most successful wildlife crossings. Completed in 2014, the crossings include 38 underpasses and six overpasses, or bridges. They prevent the park's animals, such as grizzly bears and cougars, from being struck while trying to cross the Trans-Canada Highway, which divides the park in half. According to Parks Canada, Banff's crossing system has reduced collisions with wildlife by more than 80%. 课后巩固 多维提能 Safe pathways for wildlife have been built in several U．S. states, including Arizona, Utah, and Wyoming. In Washington State, Garvey-Darda is part of a major project. She's helping to design a set of about 20 wildlife crossings. “Banff has been the best model for us，” she says. The Washington State crossings are being built along a 15-mile stretch of Interstate 90 (I-90), one of the country's longest highways. This section of the highway cuts across the Cascade Range. It has affected the migration patterns of animals in the area. 课后巩固 多维提能 Construction of the 20 crossings is expected to be completed by 2029. So far, six underpasses and one overpass have been built. Garvey-Darda says these crossings have already made a difference to migrating animals. “We now have close to 5，000 deer and elk(麋鹿) going through the underpasses，” she says. “All of these animals were potential accidents.” 课后巩固 多维提能 Washington locals can volunteer to plant vegetation on the I-90 overpass. Garvey-Darda says the plants will encourage animals, including her beloved pikas, to use the crossings. “It's important to be active，” she says. “Don't wait until a species is endangered.” 【解题导语】　本文是一篇说明文。文章介绍了野生生物学家加维·德拉达通过在华盛顿州建造野生动物通道来保护动物免受车辆碰撞。 课后巩固 多维提能 9．What is a threat to wild animals according to the passage? A．Failing to find enough food. B．Being hit when crossing roads. C．Having their habitats destroyed. D．Getting lost during their migration. 解析：细节理解题。根据第一段中的“The Federal Highway Administration says...These collisions hurt wildlife and people.”可知，野生动物面临的一个威胁是过马路时被车辆碰撞。 √ 课后巩固 多维提能 9 10 12 11 4 5 6 7 2 3 1 8 10．What do we know about Banff's crossing system? A.It is advanced. B．It is simple. C．It works well. D．It needs improvement. 解析：推理判断题。根据第三段中的“According to Parks Canada, Banff's crossing system has reduced collisions with wildlife by more than 80%.”可推知，班夫国家公园的过路系统在减少动物过马路被车辆碰撞方面起到了很好的作用。 √ 课后巩固 多维提能 9 10 12 11 4 5 6 7 2 3 1 8 11．What can we infer from Garvey-Darda's words in the last two paragraphs? A.Humans are too passive in protecting animals. B．More and more animals are using the crossings. C．More and more animals are becoming endangered. D.Humans are responsible for killing so many animals. 解析：推理判断题。根据第五段中的“We now have close to...through the underpasses” 和第六段中的“the plants will encourage animals...to use the crossings”可推知，正在有越来越多的动物使用这些通道。 √ 课后巩固 多维提能 9 10 12 11 4 5 6 7 2 3 1 8 12．Which of the following can be the best title for the passage?
