Willamette Valley Scenic Bikeway It's exciting: riding past fields of world-class hops, rolling along hills dotted with rows of wine grapes, leaning your bike outside a small cafe at a rural crossroads for a strong cup of coffee.The bounty of Oregonis on full display as you cycle the nation's first scenic bikeway, 134 miles down a river valley snaking between the Coast Rangeand Cascade Range. Old West Scenic Bikeway The 174-mile Old West Scenic Bikeway weaves through rangeland, along rushing rivers and toward an unending desert.And around these parts, folks are known for their put-your-feet-up hospitality (热情)． Cascade Siskiyou Scenic Bikeway This 55-mile route starts and ends inAshlandand includes 5,000 feet of climbing.From town, you climb through tropical grassland into deep forests.Stay inAshland.Or turn the ride into an overnight ride and stay in a cabin in the woods. McKenzie Pass Scenic Bikeway This 38-mile route climbs through a forest to a 65-square-mile lava flow with 360-degree views of the Cascadian Volcanoes.The 25-mile, 4,000-foot descent (坡道) to the McKenzie River has brake-burning turns through the forest.Professional tip: The McKenzie Highway is closed during the winter, but for several weeks before it opens to cars in the spring, the road is only managed for non-motorized use. 【语篇解读】　本文是应用文。文章介绍了俄勒冈州的四条自行车骑行路线。 1．Which is the first scenic bikeway in the USA?

A．It is closed in winter. B．It is inaccessible by car. C．It is easy for bicyclists of all levels. D．It is famous for cabins in the woods. A　细节理解题。根据McKenzie Pass Scenic Bikeway部分中的The McKenzie Highway is closed during the winter可知，这条路线在冬季封闭。 B Your biology teacher may insist that science is not a laughing matter, but scientists would argue that laughter is a scientific matter.These scientists have found a basic difference in how men and women laugh. Jo-Anne Bachorowski and her research team recorded the laughter of 97 volunteers.The volunteers watched clips (电影片段) from funny movies.The scientists were surprised at the variety of sounds people made when they laughed.Rarely did they hear sounds that we stereotype as laughter such as“tee hee hee”or“ho ho ho.”More often they heard vowel (元音) sounds such as those heard in“car”(aah) or“glow”(ooh)．What's more, women tended to laugh in a more sing-song way, while men more often grunted (发出哼声)． The researchers caution that this work was limited to people in the United States, so the results may not be universal.Bachorowski predicts that cultural influences may affect what causes people to laugh, but it probably does not change how we laugh. Although we do laugh at jokes and funny movies, 80% of our laughter occurs during everyday comments in everyday social situations.Robert Provine, a neuroscientist who studies laughter, went to places such as shopping malls and collected more than 1,200 conversations.He found that the person speaking laughed 46% more than the listeners and that women laughed more often than men.Furthermore, the response to the speaker depended on the speaker's gender.People, whether male or female, laughed more readily in response to a male speaker.The researchers also observed that laughter rarely interrupted speech.Instead, laughter came at the end of a phrase, much like punctuation following a written sentence. Humans may be“tuned (使协调)”for laughter much in the same way that songbirds are“tuned”for song—especially their own specific family song.Certain nerve cells (神经细胞) in the songbird's brain“fire”in response to hearing his song.Perhaps humans have specialized nerve cells that respond to laughter.After all, laughter is a specialized vocalization, and we are“tuned”to respond to vocalizations in language. 【语篇解读】　本文是说明文。研究发现，男性和女性笑的方式不同。 4．How did Bachorowski's team do their research? A．By studying how people laugh globally. B．By analyzing cultural influences on humans' laughter. C．By observing everyday conversations in shopping malls. D．By studying sounds made by volunteers in response to funny movies. D　细节理解题。根据第二段中的Jo-Anne...recorded the laughter of 97 volunteers.The volunteers watched clips from funny movies可知，Bachorowski和她的团队让志愿者观看喜剧电影的片段，然后观察并研究他们的笑声。 5．What did Bachorowski's team find? A．Men and women laugh differently. B．Vowel sounds are rarely heard in laughter. C．Cultural influences determine how people laugh. D．People think jokes are funnier than comedy movies. A　细节理解题。根据第二段中的What's more, women tended to laugh in a more sing-song way, while men more often grunted可知，Bachorowski和她的团队发现男性和女性笑起来不同。 6．Which of the following agrees with Provine's finding? A．Men laugh more often than women. B．Listeners laugh more often than speakers. C．Laughter may easily interrupt a conversation. D．Male speakers make people laugh more easily. D　细节理解题。根据第四段中的People, whether male or female, laughed more readily in response to a male speaker可知，Provine发现人们更容易被男性说话者逗乐。 7．Why does the author mention songbirds in the last paragraph? A．To describe how birds laugh. B．To praise the beautiful songs they sing. C．To explain how humans' laughter works. D．To show that laughter also exists among animals. C　推理判断题。根据最后一段中的Humans may be“tuned”for laughter much in the same way that songbirds are“tuned”for song和Perhaps humans have specialized nerve cells that respond to laughter可知，作者提到鸣鸟是为了解释人类笑的机制。 C Greenhouse gas emissions would rise if all farms in England and Wales went organic.Though the emissions of each farm would go down, much more food would have to be imported, as the amount they would produce would decrease greatly. “The key message from my perspective is that you can't really have your cake and eat it，”says Laurence Smith, now at the Royal Agricultural University in the UK, who was part of the team that ran the numbers.Smith is a supporter of organic farming and says“there are a lot of merits of the organic approach”， but his analysis shows that organic farming has downsides too. Farming and changes in land use, such as cutting down forests, are responsible for a third of all greenhouse gas emissions.That means reducing farming emissions and the land needed for farming is required to limit further global warming. Smith and his colleagues found that emissions per unit of food are, on average, 20 per cent lower for organic crops and 4 per cent lower for organic animal products.However, organic harvests per hectare (公顷) are also lower on average.For wheat and barley, for instance, harvests are just half of those of conventional farms.This means 1.5 times as much land would be needed to grow the same amount of these foods. The estimated increase in emissions varies greatly, depending on where the extra farmland comes from.If only half comes from turning grassland into farms, the increase could be as low as 20 per cent.If grassland that would otherwise have been reforested is turned into farmland, emissions could nearly double. This doesn't necessarily mean people should stop eating organic produce, says Smith.People might choose organic food for other reasons, such as to reduce their pesticide exposure (though contrary to popular belief, organic farmers do use pesticides) or for the sake of wildlife. Going 100 per cent organic could also harm global biodiversity.The extra land used for farming would mean the land available for wildlife would be smaller and more fragmented (碎片化的)． Smith says the best option may be to use some organic and conventional farming methods at the same time. 【语篇解读】　本文是议论文。有机农作物能否从根本上减少温室气体的排放？ 8．Why may greenhouse gas emissions increase if a country goes organic? A．Organic farms take longer to build. B．The agricultural output will increase greatly. C．The emissions of each farm unit will increase. D．Greater demand for imported food will be created. D　细节理解题。根据第一段中的Though the emissions of each farm would go down, much more food would have to be imported, as the amount they would produce would decrease greatly可知，有机农场的产量不够，这就需要从国外进口食物，进口食物在运输过程中会产生更多的温室气体。 9．What does the underlined word“merits”in Paragraph 2 probably mean? A．Changes.　　　　 B．Challenges. C．Advantages. D．Differences. C　词义猜测题。根据划线词前的Smith is a supporter of organic farming和划线词后的but his analysis shows that organic farming has downsides too可知，Smith支持有机农业，认为它有诸多优势，但是他的分析显示有机农业也有缺点。 10．What did Smith and his colleagues find? A．Organic harvests per unit are greater than traditional harvests. B．Organic farming needs more farmland to feed a country. C．Global warming could be brought under control. D．Land was not used in a responsible way. B　细节理解题。根据第四段中的This means 1.5 times as much land would be needed to grow the same amount of these foods可知，有机农场的产量少，因此需要更多的土地投入种植才能够保证足量的食物供给。 11．What is Smith's proposal? A．Stopping using pesticides. B．Eating less organic produce. C．Going back to traditional farming. D．Adopting mixed farming methods. D　细节理解题。根据最后一段的Smith says the best option may be to use some organic and conventional farming methods at the same time可知，Smith建议有机农场和传统农场同时并存。 D Alaska's Arcticis experiencing surprising changes with the effects of climate change occurring at twice the rate of the rest of the world.Significant loss of sea ice from a warming climate is one example of this change.Polar bears rely on sea ice—their primary habitat—to hunt seals, which are their primary food source.In certain regions of the Arctic, loss of sea ice has sharply reduced the ability of polar bears to hunt for seals, and it has resulted in polar bears coming to shore to look for food and den (穴居) in greater numbers. There are 19 polar bear populations throughout the circumpolar Arctic, two of which include the Chukchi and Southern Beaufort Sea Populations.The Southern Beaufort Sea population is considered the most endangered on the planet, and Defenders has prioritized (按优先顺序排列) our polar bear work to focus on this population. Defenders has a multi-pronged (多管齐下的) approach to protecting the Southern Beaufort Sea population of polar bears.We are working to protect its critical habitat, minimize climate change effects and reduce human-polar bear conflicts.To reduce human-polar bear conflicts, we promote and support a variety of coexistence measures, including the use of polar bear-proof food storage lockers and polar bear patrols (巡逻队) in Arctic communities that use non-lethal hazing and deterrence measures as a first line of defense. The Southern Beaufort Sea population of polar bears has experienced such a dramatic rate of decline in the past few decades that it's possible that this population could be extinct within our lifetime.Clearly strong measures are needed to limit greenhouse gas emissions to lessen the effects of climate change and slow the loss of sea ice. In the case of the Southern Beaufort Sea population of polar bears, in addition to reducing climate impacts, we need to continue to work to reduce human-polar bear conflicts so that community residents remain safe and fewer of these polar bears are lost to“defense of life and property”kills.Defenders is grateful to be able to work with Arctic communities, families and residents to do what we can't to ensure community safety and preserve and ultimately recover this polar bear population. 【语篇解读】　本文是说明文。全球气候变暖威胁着北极熊的生存，如何让人类与北极熊共存呢？ 12．How has climate change influenced polar bears? A．It has threatened their freedom and security. B．It has created increasing conflicts among them. C．It has caused a dangerous population imbalance. D．It has destroyed their habitats and food source access. D　细节理解题。根据第一段中的Polar bears rely on sea ice—their primary habitat...loss of sea ice has sharply reduced the ability of polar bears to hunt for seals, and it has resulted in polar bears coming to shore to look for food and den in greater numbers可知，全球气候变暖使得北极的海冰大面积融化，而海冰是北极熊的主要栖息地，并且海冰的消失大大降低了北极熊捕猎海豹的能力，这使得越来越多的北极熊来到岸边寻找食物，并在此栖息。 13．What does Paragraph 3 mainly focus on? A．The effects of human activities on polar bears. B．The measures taken to preserve polar bears. C．The current living situations of polar bears. D．The favorable environment for polar bears. B　段落大意题。根据第三段中的a multipronged approach to protecting the Southern Beaufort Sea population of polar bears和protect its critical habitat, minimize climate change effects and reduce humanpolar bear conflicts以及we promote and support a variety of coexistence measures, including the use of polar bearproof food storage lockers...deterrence measures as a first line of defense可知，该段主要介绍了Defenders组织为保护北极熊所采取的措施。 14．What can be learned about the Southern Beaufort Sea population of polar bears? A．Their population has recovered. B．Their self-protection efforts have worked. C．Some have lost their lives to residents' defense kills. D．Some have adapted to changes in their surroundings. C　推理判断题。根据最后一段中的we need to continue to work to reduce humanpolar bear conflicts...fewer of these polar bears are lost to“defense of life and property”kills可推知，有的北极熊死于当地居民为了保护生命和财产安全的防卫性杀戮。 15．Which of the following can be the best title for the text? A．Encountering polar bears B．Coexisting with polar bears C．Polar bears are making a comeback D．Polar bears may survive the ice melt B　标题归纳题。通读全文可知，全球气候变暖使得北极的海冰大大减少，这不仅破坏了北极熊赖以生存的栖息地，也大大降低了它们捕猎海豹的能力，越来越多的北极熊来到岸边寻找食物和洞穴；当地的居民为了保护生命和财产安全而对北极熊采取了防卫性杀戮，这使得北极熊的数量急剧下降，Defenders组织采取一系列措施来保护北极熊，减少北极熊和人类之间的冲突，让人类与北极熊共存，B项作标题最能体现文章的主旨。 第二节(共5小题；每小题2.5分，满分12.5分) 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。 At Mia's“Reuse-a-Palooza”party, eight colored bins contained items of matching colors.Staff arranged them in rainbow order.Materials included pipe cleaners, buttons, rings, funnels and tubes (管子). __16__ Mia, for example, created a pair of glasses from wire, hoops, and orange paper.Mia's party is one of several themed parties at Pittsburgh Center for Creative Reuse.

When we'd written our sentences, Ms.Cook said，“It's time to get ready for art.”She passed out colored markers and crayons.“Everyone, draw a picture of Bob on your poster.We'll hang the posters in the hallway (走廊) on our way to lunch.” After lunch, we all rushed to the terrarium.Bob had not returned.“Back to your seats，”said Ms.Cook.“It's time for science.I suppose Mr.Henderson wouldn't mind if we made an unscheduled visit to the library.”Ms.Cook had turned our search into our art lesson.Now Bob was becoming our science lesson.Bob's disappearance was looking suspicious (可疑的)． “We need some books about snakes，”I explained to Mr.Henderson when we entered the library.Mr.Henderson disappeared between two shelves and returned with an armful of books.Ms.Cook divided the class into six groups of four.Each group read a book about snakes. 注意： 1．续写词数应为150左右；2.请按如下格式在相应位置作答。 When we returned to class, each group gave a book report._____________________________ ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ “Everyone take out a piece of paper and write Ms.Butler a thank-you note，”said Ms.Cook. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ One possible version： When we returned to class, each group gave a book report.I was explaining why some snakes don't make good pets when Ms.Butler, the principal, walked in with Bob around her arm.“Look what I found under my desk，”said Ms.Butler，“I knew it must be your snake because he looks just like the pictures on your posters.He is very gentle.”Ms.Cook put Bob back into the terrarium.She made sure the lid was securely in place.“It was very nice of Ms.Butler to return Bob, since she doesn't like snakes，”said Ms.Cook. “Everyone take out a piece of paper and write Ms.Butler a thank-you note，”said Ms.Cook，“Double-check your spelling and grammar，”she added.As Ms.Cook collected our notes, the bell rang.I was first in line behind Ms.Cook.“Ms.Cook, I think I know how Bob escaped，”I said，“I think he had help.But his disappearance made school very interesting.Thanks for the fun day.”Ms.Cook smiled. 学科网（北京）股份有限公司 $
