(全国统考)2021高考英语一轮复习第1编话题七Book7Unit3Underthesea课时作业(含解析)

Unit 3 Under the sea课时作业Ⅰ.阅读理解(2019·北京高考)By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz, a scientist in MIT's Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turngreener. “Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing.”And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It'll be a while before we can statistically show that the changes are happening because of climate change,”Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”篇章导读:本文是一篇说明文。

调查表明,由于气候变暖,全球的海洋将会变得更蓝、更绿。

1.What are the first two paragraphs mainly about?A.The various patterns at the ocean surface.B.The cause of the changes in ocean colour.C.The way light reflects off marine organisms.D.The efforts to fuel the growth of phytoplankton.答案:B 段落大意题。

文章第一段点题:由于气候变暖,全球的海洋将会变得更蓝、更绿。

第二段介绍由于光从生物体反射的方式,这些浮游植物在海洋表面形成了五颜六色的图案;气候变化又使得这些浮游植物在某些区域加速生长而在其他地方有所减少,导致海洋表面的颜色变化。

由此可知前两段讲了海洋颜色变化的原因,故B项正确。

2.What does the underlined word“vulnerable” in Paragraph 3 probably mean?A.Sensitive. B.Beneficial.C.Significant. D.Unnoticeable.答案:A 词义猜测题。

画线词后一句提到,气候变暖改变了海洋的主要特点并能影响浮游植物的生长,因为它们要生长不仅仅需要阳光和二氧化碳,也需要营养。

由此可知,这些浮游植物对海洋变暖很敏感,故A项正确。

3.What can we learn from the passage?A.Phytoplankton play a declining role in the marine ecosystem.B.Dutkiewicz's model aims to project phytoplankton changes.C.Phytoplankton have been used to control global climate.D.Oceans with more phytoplankton may appear greener.答案:D 推理判断题。

文章倒数第二段提到这些浮游植物是海洋食物链的基础,如果某些种类的浮游植物消失了,会影响能存活的鱼的类型,从而影响海洋食物链,并结合文章第四段倒数第二句可知浮游植物多的区域海水会变得更绿,故D项正确。

4.What is the main purpose of the passage?A.To assess the consequences of ocean colour changes.B.To analyse the composition of the ocean food chain.C.To explain the effects of climate change on oceans.D.To introduce a new method to study phytoplankton.答案:C 主旨大意题。

文章主要论述了随着气候变暖,全球的海洋将会变得更蓝、更绿,即气候变化对海洋有影响,故C项正确。

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 of having the sea at my side. The first time I went to Halfmoon 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 country 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 would serve as a place where the ocean'sspecies will all have a safe place forever.Together, Angus and I created a little video and we hope it will inspire people to be a part of the movement. Angus also shares 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 oceanspecies.篇章导读:本文是一篇记叙文。

After graduation, they decided to cycle along the Mekong River with their cousins. ②Wang Wei is determined. Although it is difficult to travel along the Mekong River by bike, she insisted that they find the source of the river and begin their journey there.③Their travel started from the atlas of the Mekong River, beginning in a glacier on a mountain in Qinghai Province. At first the river is small, and then it begins to move quickly. It becomes rapids as it passes through deep valleys, travelling across western Yunnan Province. Sometimes the river becomes a waterfall and enters wide valleys. Half of the river is in China. After it leaves China, the Mekong becomes wide, brown and warm. With slow pace, it winds its way to the South China Sea.图二:概要写作①②Li Daiyu and Liu Qian took the train in Canada from west to east. Canada isthe second biggest country in the world. It is 5,500 km from coast to coast. ③Their cousins' friend, Danny Lin, took them to the train station to catch “The True North”.④As they went eastward, they saw beautiful scenery as well as cities. Vancouver is surrounded by mountains, lakes, forests and rivers. When the cousins settled down in the seats, they looked out of the window. They saw mountain goats and even a grizzly bear.Calgary is famous for its Stampede. Many of the cowboys from all over North America have a gift for riding wild animals. After they went through a wheat­growing province, they came to a busy port, Thunder Bay, which is at the top of the Great Lakes. When they were sleeping, the train took them towards Toronto.图三:概要写作①The full name of England is the United Kingdom of Great Britain and Northern Ireland. ②It consists of four parts: England, Wales, Scotland and Northern Ireland. People always think Wales is a part of England. The flag of the UK is called the Union Jack.③The four countries have different educational and legal systems as well as different football teams. England is the largest of the four countries and it is divided into three parts. You find most of the people settled in the South, but most of the large industrial cities in the Midlands and the North. For historical architecture you have to go to older but smaller towns built by the Romans, where you will find out more about British history and culture. ④The capital of the UK is London, which has many great places of interest.图四:概要写作①When we arrived at the whaling station, I saw Old Tom throw itself out of the water and crash down again to show that there was a whale out there. Old Tom swam by the boat, showing us the way. As we got closer, I could see the whale being attacked by a pack of about six other killers, who were working as a team. The killers stopped it breathing, while others were stopping it fleeing. The whale was hit to death, then the killer whales dragged it into the depth of the sea and had a good feed on its tips and tongue.②One day, James was washed off the boat. The sea was rough. The waves were carrying him further and further. James was very terrified of being abandoned. It took over half an hour to get the boat back to James. And when we approached him, I saw him being held up in the water by Old Tom.图五:概要写作①Xie Lei boarded a plane for London six months ago to complete a business qualification. She is now halfway through the preparation year. At the beginning, she had to learn almost everything again. She lives with a host family, which gives her the opportunity to learn more about everyday life and customs in her new country.②Once she wrote her first essay to her tutor, but she only got an E because she used others' ideas. ③Later she created her own ideas using others' opinion to prove her own, which was thought highly of by her tutor. Now she has got used to the life and she feels much more at home and is going to join a few university clubs in order to have a balance between study and a social life. We wish Xie Lei all the best in her new enterprise.1.The first day of our trip saw us exposed to the Great Wild Goose Pagoda, famous for its long history and leaning shape.第一天我们游历了大雁塔,该塔以历史悠久和倾斜的外观而出名。

Unit 2 Robots课时作业Ⅰ.阅读理解(2020·全国新高三开学联考)A robot created by Washington State University (WSU) scientists could help elderly people with dementia and other limitations live independently in their own homes.The Robot Activity Support System, or RAS, uses sensors (传感器) equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owners to objects like their medication or a snack in the kitchen.“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.Currently, about 50 per cent adults over the age of 85 need assistance with everyday activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial pressure on the healthcare system by making it easier for older adults to live alone.RAS is the first robot researchers have tried to apply to their smart homeenvironment. They recently published a study in the journal Cognitive Systems Research that shows how RAS could make life easier for older adults struggling to live independently.“While we are still in an early stage of development, our initial results with RAS have been promising,”Minor said. “The next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what video reminders and other preferences they have regarding the robot.”篇章导读:本文是一篇说明文。

Starting in July, the world's first passenger drone (无人机), the EHANG 184, will be available to passengers.The shuttle, released in Las Vegas in January 2021, weighs 440 pounds and can fly at heights of up to 11,500 feet. The egg­shaped vehicle has room for a single passenger weighing up to 220 pounds and a small suitcase. Though the flying taxi can reach speeds of up to 100 mph, it will typically operate at about 62 mph.Passengers can ask for the flying taxi to pick them up from appointed zones using a smartphone app. Passengers strap into the seat, select a destination on the touch screen, and enjoy the flight. To ensure the passenger's safety, all flights are monitored remotely by a control room on the ground.In the unlikely event that any of the components malfunction or disconnect, the drone will make an emergency landing to ensure the customer's safety. It's also programmed to ensure its route won't affect that of another drone. While having no control over the remotely piloted vehicle may appear scary, the producer, China­based EHANG, says, “It is the safest, smartest and eco­friendly low altitude autonomous flying vehicle.” Any drawback? The EHANG 184 has a battery life of 30 minutes and a flight range of just 31 miles. Also unknown is the cost of each ride.Though the flying taxi seems advanced, it is not the first driverless transportation option available to Dubai's residents. As part of its goal to have 25% of the public transportation automated by 2030, the authorities have built the world's longest driverless metro and introduced serf­navigating shuttles. Offi cials recently also partnered a US company to build supersonic speed pods to carry passengers between Dubai and Abu Dhabi.篇章导读:本文是一篇科普说明文,介绍了一种迪拜正预备投入供公交出租使用的自动驾驶低空飞行器——EHANG 184。
