2017-2018学年高一英语(北师大版) 必修三全册教学案Killer whales have the second­heaviest brains among marine mammals (after Sperm whales, which have the largest brain of any animal). They can be trained in captivity (囚禁；关押) and are often described as intelligent, although defining and measuring “intelligence” is difficult in a species whose environment and behavioral strategies are very different from those of humans.Killer whales imitate others, and seem to deliberately teach skills to their kin. Off the Crozet Islands, mothers push their calves onto the beach, waiting to pull the youngster back if needed.People who have interacted closely with killer whales offer numerous anecdotes demonstrating (证明) the whales' curiosity, playfulness, and ability to solve problems. Alaskan killer whales have not only learned how to steal fish from Iong lines, but also have overcome avariety of techniques designed to stop them, such as the use of unrated (未分级的；未征税的) lines as decoys. Once, fishermen placed their boats several miles apart, taking turns retrieving (恢复；取回) small amounts of their catch, in the hope that the whales would not have enough time to move between boats to steal the catch as it was being retrieved. A researcher described what happened next: The killer whale's use of dialects and the passing of other learned behaviours from generation to generation have been described as a form of animal culture.Section_ⅠWarm­up__&_Lesson_1_—_Pre­reading[原文呈现]VIKING VOYAGES①TO AMERICAThe Vikings②were the first Europeans to reach America③.

Known for his jumping ability, Oxygen, a Czech, who jumped a nearly 10­foot ­wide abyss (深渊). Today, Petr Kops, 21, is wearing Oxygen's pants. “I did not know Oxygen personally, but my sister did，” Kops said. “I wear his trousers for good luck.”Minutes later, Kops was standing at th e edge of a 70­foot abyss called Broken Bones.While it may seem suicidal (自杀的), jumping across a gap is actually an extreme sport that is gaining in popularity. Called rock jumping, or simply jumping, this activity is taking place in the Adrspach­Teplice Rocks, a remote nature preserve in the northeast part of the Czech Republic. Known for its 11 square miles of sandstone, the region has been loved by lifelong rock climbers. “The aim is to get to the top of as many towers as you can.” said Vladimir Prochazka, known as June Bug, a 59­year­old climber and a collector of Czech rock climbing histories.Jumping is often the most possible way to get to the tower. In most cases, climbers jump with a rope tied around their waist. If they miss the landing —which is not uncommon —they will fall into the wall of the base tower. “Jumping requires fearlessness，” Prochazka said. “Broken or damaged bones are fairly common.” Still, there are those who prefer to experience by jumping without a rope. Among the most well­known of these adventurers are Petr Prachtel and his wife, Zorka, who helped create the sport in the 1960s. They pioneered countless jumps, sometimes without the safetyof a rope.1．What does “pants” probably mean in the first paragraph?A．Shoes. B．Trousers.C．Jackets. D．Shirts.2．Why did Petr Kops wear Oxygen's trousers?A．Because he knew Oxygen very well.B．Because Oxygen was good at wearing.C．Because he wanted to be lucky.D．Because Oxygen had poor jumping ability.3．Rock jumping is ________．A．becoming less and less popular for it is so far awayB．too dangerous to attract any peopleC．appeared in the southeast part of the Czech RepublicD．loved by people who can face the danger答案：Ⅰ.1.adventure 2.presenters 3.horizon 4．organisations 5.extra 6.desert 7.luggage 8.altitude 9.footprint 10．maximumⅡ.1.took off 2.went down 3.right now 4.differs from 5.thinking aboutⅢ.1.not only; but also 2.Although in poor health 3.Once a worker 4．When very young 5.While at collegeⅣ.1.walking 2.down 3.for 4．experienced 5.but 6.including fortable 8.from 9.into 10．tryingⅤ.语篇解读：小男孩被送去寄宿学校，他认为没人爱他，所以成绩下降。

携手推进“一带一路”建设——在“一带一路”国际合作高峰论坛开幕式上的演讲(节选)（2017年5月14日，北京）中华人民共和国主席习近平Ladies and Gentlemen,Dear Friends,Over 2,000 years ago, our ancestors, trekking across vast steppes and deserts, opened the transcontinental passage connecting Asia, Europe and Africa, known today as the Silk Road. Our ancestors, navigating rough seas, created sea routes linking the East with the West, namely, the maritime Silk Road. These ancient silk routes opened windows of friendly engagement among nations, adding a splendid chapter to the history of human progress. The thousand-year-old "gilt bronze silkworm" displayed at China's Shaanxi History Museum and the Belitung shipwreck discovered in Indonesia bear witness to this exciting period of history.女士们、先生们、朋友们！2000多年前，我们的先辈筚路蓝缕，穿越草原沙漠，开辟出联通亚欧非的陆上丝绸之路；我们的先辈扬帆远航，穿越惊涛骇浪，闯荡出连接东西方的海上丝绸之路。

That can cause waste water systems to overflow and send pollutants into rivers and other waterways. To fight the problem, several cities in the United States are starting programs like rooftop gardens.A team at the University of the District of Columbia in the nation’s capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five “green roofs” for the university. He says he is excited about the project because “it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren’t doing anything really became something that was about urban agriculture.” Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects.In cities, “you don’t have that many spaces to choose from and so rooftops are just (unused) space,” says Caitlin Arlotta. She is a student in the school’s Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. “We also have our own farm experiments,” Arlotta said. “Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best.”Sandy Farber Bandier helps run UDC’s Master Gardener program. It seeks to improve cities and make them beautiful by training people to become Master Gardeners. She says she’s been surprised by the garden’s output. “My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need.” She also likes being able to show people who live in D. C. and others beyond the nation’s capital what and how food can be grown on a rooftop. “This is the future for food. You grow it here, you prepare it in a commercial kitchen, you distribute through farmers markets, food trucks, and then you recycle.”1. What do we know about the rooftop gardens?A. Rooftop gardens are very common in average neighborhoods.B. There are many sorts of plants there which help take in rainwater.C. They’re playing an important role in the city’s food supply.D. Rooftop gardens are no more than containers to collect rainwater.2. What can we infer from Paragraph 3?A. Rooftops can offer enough space to plant crops.B. Many plants like strawberries can grow well on rooftops.C. Some university students are participating in the Urban Agriculture program.D. The plants in rooftop gardens are attractive to many insects.3. How does Sandy Farber Bandier feel about the future of rooftop gardens?A. Confident.B. Doubtful.C. Worried.D. Ambiguous.4. What is the best title for the text?A. Rainwater Necessity for Plant LifeB. Green Roofs-The Future of Urban AgricultureC. The United States’ Agriculture ProgramD. Rooftop Gardens-Food ParadiseBSteven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein’s jobs is defending an industry behind the plastic shopping bags.Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts (收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.Among the bag makers’ argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.Environmentalists don’t dispute (质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.5. What has Steven Stein been hired to do?A. Help increase grocery sales.B. Recycle the waste material.C. Stop things falling off trucks.D. Argue for the use of plastic bags.6. What does the word “headwinds” in paragraph 2 refer to?A. Bans on plastic bags.B. Effects of city development.C. Headaches caused by garbage.D. Plastic bags hung in trees.7. What is a disadvantage of reusable bags according to plastic-bag makers?A. They are quite expensive.B. Replacing them can be difficult.C. They are less strong than plastic bags.D. Producing them requires more energy.8. What is the best title for the text?A. Plastic, Paper or NeitherB. Industry, Pollution and EnvironmentC. Recycle or Throw AwayD. Garbage Collection and Waste Control三、应用文写作(共1小题)假设你是中学生李华，你的美国笔友Chris得知你校正在积极开展“绿色校园行”活动他非常感兴趣，便写信给你，希望你介绍相关情况。
