课时作业(10) Unit 3 Period 2（Word练习）-【金榜题名】2025-2026学年高二英语选择性必修第四册高中同步学案（人教版）

课时作业(十)　Unit 3　Period 2 Ⅰ.阅读理解 A I don't think I can recall a time when I wasn't aware of the beauty of the ocean. Growing up in Australia, I had the good fortune to have the sea at my side. The first time I went to Half Moon Bay, I_suddenly_had_the_feeling_of_not_being_able_to_feel_the_ground_with_my_feet_anymore. For my 10th birthday, my sister and I were taken out to the Great Barrier Reef. There were fish in different colors，caves and layers of coral. They made such an impression on me. When I learned that only 1 percent of Australia's Coral Sea was protected，I was shocked. Australian marine life is particularly important because the reefs have more marine species than any other place on earth. But sadly, only 45% of the world's reefs are considered healthy. This statistic is depressing, so it's important for us to do everything to protect them. The hope that the Coral Sea remains a complete ecosystem has led me to take action. I've become involved with the Protect Our Coral Sea activity，which aims to create the largest marine park in the world. It will serve as a place where the ocean's species will all have a safe place forever. Together，Angus and I created a little video and we hoped it would inspire people to be part of the movement. Angus also shared many beautiful childhood memories of the ocean as a young boy，who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of underwater marine species. 【语篇解读】　本文是一篇记叙文。本文中作者借自己的个人经历来呼吁人们保护海洋生物。 1．What can be learned about the author from the underlined sentence in Paragraph 1?

A lot of oceans have witnessed a variety of disappearances and other mysteries, most of which have not been and cannot be explained by modern science. Here are some interesting unsolved sea mysteries of the world. USS Scorpion In 1968, the USS Scorpion, an American submarine, departed from the Mediterranean, for Norfolk. The crew had almost a decade of experience, and yet the sub disappeared and broke into pieces on the seafloor. There were 99 people aboard the sub, all of whom lost their lives. Baltic Sea Sub In the later half of 2014，a mysterious sub was spotted by Swedish citizens, many of whom described it as a Russian submarine, in the Baltic Sea. The military spent much time in investigating, but found no sign of the mysterious sub. Bermeja Island During the 1970s, the Bermeja Island served as a bit of a marker for Mexico and its economic zone. Around 20 years later, the island disappeared without any sign. Along with the island, numerous important documents about major oil reserves also went missing. Gulf of Mexico Shipwreck In 2001, ExxonMobil was laying the pipelines in the Gulf of Mexico when it ran into a shipwreck around 2，600 feet under the water surface. Upon exploring the shipwreck, archaeologists believed it to be under a terrible spell(咒语), as something would constantly go wrong when they went down to explore. SS Edmund Fitzgerald Lake Superior is so large that it is like an inland ocean with terrific storms. In November 1975，one such storm struck the SS Edmund Fitzgerald，which was headed to Detroit. The Edmund Fitzgerald disappeared after communications were lost. A week later，a sonar(声呐) ship found the vessel 500 feet under the water. No body was found, though. 【语篇解读】　本文是一篇说明文。海洋是整个地球上最有趣和最令人惊叹的地方之一。世界上的海洋有很多已经见证了各种各样的失踪和其他神秘事件，其中大多数还没有科学的解释。文章主要介绍了世界上一些有趣的海洋未解之谜。 5．Why does the author think of the USS Scorpion as a mystery? A．Because 99 people died aboard the sub. B．Because it lost its way towards Norfolk. C．Because the sub still sank even with the experienced crew. D．Because there is no information about the unknown sub. 解析：选C　细节理解题。根据第二段中的“The crew had almost a decade of experience, and yet the sub disappeared and broke into pieces on the seafloor.”可知船员们几乎有10年的经验，但这艘潜艇还是消失了，在海底成了碎片。由此可知，作者认为美国“天蝎号”是一个谜是因为即使有经验丰富的船员，潜艇还是沉没了。 6．What do the Baltic Sea Sub and the Gulf of Mexico Shipwreck have in common? A．A bad spell was put on both. B．Both the names of them were unknown. C．Both were found on the beaches. D．Both were said to be Russian. 解析：选B　细节理解题。根据第三段第一句可知，2014年下半年，一艘神秘的潜艇在波罗的海被瑞典公民发现，其中许多人将其描述为一艘俄罗斯潜艇。根据第五段可知，2001年，埃克森美孚公司在墨西哥湾铺设输油管道时，在海面下2，600英尺处撞见了一艘沉船。在探索沉船时，考古学家认为它中了一个可怕的咒语，因为当他们下去探索时，总会有东西出错。由此可知，波罗的海潜艇和墨西哥湾沉船的共同之处是它们的名字是未知的。 7．Which mystery is different from the others? A．SS Edmund Fitzgerald. B．Bermeja Island. C．Gulf of Mexico Shipwreck. D．USS Scorpion. 解析：选B　细节理解题。根据第四段可知大约20年后，这个岛消失得无影无踪。连同这座岛屿，大量关于主要石油储量的重要文件也消失了。而其他的谜团都是关于船只或潜艇的，由此可知，Bermeja Island的谜团与其他的不同。 Ⅱ.七选五 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 All living things in the ocean are endangered by humans polluting the water. __1__. One way is the dumping(倾倒) of certain waste materials, such as garbage and used water, into the ocean. The harmful bacteria that feed on the garbage use up much of the oxygen in the surrounding water, so other creatures in the area often don't get enough. Other substances(物质), such as radioactive waste materials, can also cause pollution. __2__. But after years of being exposed to the ocean water, the containers may begin to leak(漏). __3__. Oil is spilled into the ocean when oil ships sink or when oil wells in the ocean cannot be capped. The oil covers the gills(腮) of fish and prevents them from breathing. Diving birds get the oil on their wings and are then unable to fly. When they clean themselves, they are often poisoned by the oil. Rivers can also contribute to the pollution of oceans. __4__. Fertilizers used on the farmlands may be carried to the ocean, where they cause a great increase in the number of certain plants. Too many of some plants can actually be poisonous to fish. Worse are the pesticides(杀虫剂) carried to the ocean. These chemicals slowly build up in fish and other small animals. __5__. The build­up of these chemicals in the animals can make them ill or cause their babies to be born dead or sick. A．Fish and turtles suffer the most B．Pollution occurs in several ways C．Oil is another major source of concern D．Many rivers receive the water from farmlands E．Farmers use these artificial fertilizers to increase the crop harvest F．These substances are often placed in the water in safely sealed containers G．These animals then pass the pesticides on to the larger animals that feed on them 【语篇解读】　本文是一篇说明文。海洋面临着人类倾倒的废物、放射性物质、泄漏的石油和河流的污染，海洋中所有生物的生存都因海水被污染而受到了威胁。 1．解析：选B　根据前句“All living things in the ocean are endangered by humans polluting the water.”和后句“One way is the dumping(倾倒) of certain waste materials, such as garbage and used water, into the ocean.”可知，B项“污染以一些方式发生”承上启下，符合语境。故选B。 2．解析：选F　根据后句“But after years of being exposed to the ocean water, the containers may begin to leak(漏)．”可知，F项“这些物质经常被放到水中安全密封的容器里”符合语境。故选F。 3．解析：选C　下文多次出现了oil，由此可知此处指的是石油的泄漏对海洋造成的危害。故选C项[石油是另一个(引起人们)担心的主要原因]。 4．解析：选D　根据前句“Rivers can also contribute to the pollution of oceans.”和后句“Fertilizers used on the farmlands may be carried to the ocean...”可知D项“很多河流接收来自农田的水”承上启下。故选D。 5．解析：选G　根据前句“These chemicals slowly build up in fish and other small animals.”和后句“The build­up of these chemicals in the animals can make them ill or cause their babies to be born dead or sick.”可知G项“然后这些动物把杀虫剂传给以它们为食的更大型的动物”承上启下，故选G。 Ⅲ.完形填空 I live in a landscape surrounded by shopping malls. So it's quite __1__to feel connected to the land. I wanted __2__for my children: soil, Mother Earth and ecology. I'm a classic suburban mum. But I grew up __3__summers at my grandparents' farm. I used to pick wild blackberries, catch fishes, and run between the tows of tall corn plants. I knew what wild garlic looked like. I __4__ picked flowers from the honeysuckle and sucked the nectar (花蜜) out. I've __5__ my kids to do the same. “It's so sweet, mum，” they told me. __6__， instead of teaching my kids about the landscape, I decided to teach them a love of the land they live in. I was determined to __7__ PBL(Problem­Based Learning). So we went to the abandoned parking lot near the dead mall and __8__dandelion (蒲公英) greens, which make delicious spring salad. We dug with sticks in the wheel ruts (车辙) along the road __9__ going home. My ten­year­old kid found a special rock which __10__ him to start a rock collection. In the fall, I __11__my kids to stands of chestnut trees and showed them how to get the eatable nuts from the branches. I __12__ I had taught them some big lessons about the earth, the __13__of which they should have appreciation for. It has been revolutionary to be outside.
