Ⅰ.阅读理解 语篇解读　本文是一篇说明文。文章主要介绍受全球变暖的影响，咖啡种植受到了挑战，咖啡种植者不得不与变化的气候作斗争。 But no longer.Jeremiah Letting and other coffee farmers are suffering from rising temperatures. Some of the world’s best Coffea arabica is grown on Mount Kenya.The plant produces tastier beans than its poor cousin robusta，which often ends up in instant coffee granules(颗粒).Global warming may reduce the total area that is most suited to growing arabica beans by about half by 2050，according to a recently published paper. Although coffee is only Kenya’s fourth-largest export，it directly or indirectly provides an income for about 6 million people，which accounts for over a tenth of the entire population，according to the Kenyan government.“People are not even able to have three meals a day without a secure income，” Mr Letting says. Some farmers are trying to adapt to warming by moving uphill.Yet this pushes them into areas long used for growing tea，threatening tea growth.Kenya’s government-funded Coffee Research Institute is trying to find other solutions，such as encouraging farmers to plant trees to shade their coffee bushes.It also suggests growing a hybrid(杂交植物)，Arabusta，to combine the hardiness(耐寒性) of robusta with the flavour of arabica.People who are particular about coffee may turn up their noses at it，but they may have little choice but to swallow it. Another option may be entirely new varieties.Researchers at the Royal Botanic Gardens in London，are investigating a wild type of coffee，Coffea stenophylla.It is delicious and can also take the heat.But it produces less coffee beans than existing varieties and it may be years before it is widely grown.Without a breakthrough of some sort，Vern Long of World Coffee Research warns，“We’re just going to be drinking instant coffee.” 1.What’s the effect of global warming on coffee farming? A.More export of coffee for farmers. B.Less revenue for the government. C.Moving downhill for suitable farmlands. D.Reduced production of tasty coffee beans. √ 细节理解题。根据第三段中的“Global warming may reduce the total area that is most suited to growing arabica beans by about half by 2050，according to a recently published paper.”可知，全球变暖使得美味的咖啡豆产量减少。故选D。 解析 2.What does the underlined part “turn up their noses at it” probably mean? A.Pay high attention to the coffee. B.Sing high praise for the coffee. C.Become interested in the coffee. D.Feel unsatisfied with the coffee. √ 词义猜测题。根据画线部分前一句可知，建议种植一种杂交品种Arabusta，将robusta的耐寒性与arabica的味道结合起来。画线部分所在句中的“are particular about”意思是“对……挑剔”；再结合后半句“but they may have little choice but to swallow it”可知，对咖啡特别挑剔的人对这种杂交品种咖啡的味道很不满意，但是别无选择。所以turn up their noses at it为“对这种咖啡不满意”之意。故选D。 解析 3.How does Vern Long feel about the future of coffee production? A.Cautious. B.Uncertain. C.Concerned. D.Optimistic. √ 观点态度题。根据最后一段中的“Without a breakthrough of some sort，Vern Long of World Coffee Research warns，‘We’re just going to be drinking instant coffee.’”可推断，Vern Long对未来的咖啡生产很担忧。故选C。 解析 4.What can be the best title for the text? A.Arabica Coffee Beans Are Dying Out in Kenya B.Coffee Farmers Struggle Against Climate Killer C.Short Supplies Are Letting Tea Lovers Down D.Kenyan Tea Exports Decline in World Trade √ 标题归纳题。根据第二段中的“Jeremiah Letting and other coffee farmers are suffering from rising temperatures”及全文可知，文章主要介绍受全球变暖的影响，咖啡种植受到了挑战，咖啡种植者不得不与变化的气候作斗争。所以“咖啡种植者与气候杀手斗争”作为文章标题最为合适。故选B。 解析 B In order to help discover spoilage(变质)and reduce food waste for supermarkets and consumers，researchers have developed new low-cost，smartphone-linked，eco-friendly spoilage sensors for meat and fish packaging. 语篇解读　本文为科普类说明文。为了测定食物的新鲜度和减少食物浪费，研究人员开发了一种新的低成本智能和环保的肉类和鱼类包装变质传感器，希望它能很快地投入使用，并且应用于更广泛的领域。 One in three UK consumers throw away food just because it reaches the use-by date(保存期)，but 60%(4.2 million tonnes)of the ￡12.5 billion-worth of food we throw away each year is safe to eat. The researchers，whose findings were published in ACS Sensors，say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable. The sensors cost two US cents each to make.Known as “paper-based electrical gas sensors (PEGS)”，they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products.The information provided by the electronic nose is received by a smartphone，and then you can know whether the food is fresh and safe to eat. The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes(电极)onto a special type of paper.The materials are eco-friendly and harmless，so they don’t damage the environment and are safe to use in food packaging.The sensors，combined with a tiny electronic system，then inform nearby mobile devices，which identify and understand the data about spoilage gases. Lead author Dr Firat Guder，of Imperial’s Department of Bioengineering，said，“Although they’re designed to keep us safe，use-by dates can lead to eatable food being thrown away.They don’t always reflect its actual freshness.In fact，people often get sick from foodborne diseases due to poor storage，even when an item is within its use-by date.” “These sensors are cheap enough so we hope to see supermarkets using them within three years.Our goal is to use PEGS in food packaging to reduce unnecessary food waste.” The authors hope that PEGS could have applications beyond food processing，like sensing chemicals in agriculture，air quality，and detecting disease markers in breath like those involved in kidney disease. 5.What is the function of PEGS according to the text? A.To improve the service of stores. B.To help supermarkets store foods. C.To improve the taste of food products. D.To help people test food freshness. √ 细节理解题。根据第一段内容可知，PEGS是用来帮助人们测试食物的新鲜度以减少食物浪费的，故选D。 解析 6.What role does the smartphone play while PEGS are functioning? A.It acts as an electronic nose. B.It reads the data collected by PEGS. C.It discovers the spoilage gases from foods. D.It helps print the gas sensors onto paper. √ 细节理解题。根据第四段中的“The information provided by the electronic nose is received by a smartphone，and then you can know whether the food is fresh and safe to eat.”可知，智能手机会在PEGS运行时读取由它收集的数据，故选B。 解析 7.What does Dr Firat Guder say about use-by dates? A.They are not completely reliable. B.They can help reduce food waste. C.They are not accepted by consumers. D.They are based on scientific research. √ 推理判断题。根据倒数第三段中的“Although they’re designed to keep us safe，use-by dates can lead to eatable food being thrown away.They don’t always reflect its actual freshness.”可知，Firat Guder博士认为，保质期并不完全可靠，故选A。 解析 8.What does the author mainly talk about in the text? A.The process of researching spoilage sensors. B.Use-by dates’ influence on supermarkets and consumers. C.A new technology in packaging to reduce food waste. D.The application of spoilage sensors beyond food processing. √ 主旨大意题。通读全文，尤其根据第一段可知，本文介绍了一种新型的可以减少食物浪费的变质传感器，该技术有望在食品包装中应用，并取代靠使用日期来断定食物新鲜度的老方法，故选C。 解析 You might say I found marathon，step by step.Or perhaps it found me.I was 1 an athlete growing up.In fact，I have a hard time 2 that term to myself even today. 1.A.always B.rarely C.never D.nearly 2.A.pointing B.applying C.turning D.spreading Ⅱ.完形填空 语篇解读　本文是一篇记叙文。文章讲述了作者喜欢上马拉松的过程和这项运动对作者的影响。 √ √ 1.根据上文“You might say I found marathon，step by step.”和下文“I really didn’t believe I could .Rick locked eyes with me and said，‘Trish，you’ve done enough training.You’ll finish！’ ...He gave me the I needed.”可推知，作者并不擅长运动，在之前的成长过程中从来没当过运动员。故选C。 2.根据下文“that term to myself”可推知，作者觉得很难把“运动员”这一专有名词用在自己身上，apply sth to sb是固定短语，意为“把……应用于……”。故选B。 解析 It started when I joined a group of women in my neighborhood for a daily three-mile walk.At first it was 3 .But soon，my body adjusted and I wanted 4 . 3.A.hard B.relaxing C.unfamiliar D.exciting 4.A.some B.both C.more D.none √ √ 3.根据下文“But soon，my body adjusted”可知，一开始作者的身体没有适应，所以会觉得很难。故选A。 4.根据上文“a daily three-mile walk”和下文“Before long，I was running 5 miles.”可知，作者由一开始的步行3英里转变到跑步5英里，说明在身体适应后，作者想要进行更多运动。故选C。 解析 Before long，I was running 5 miles.Then I set a goal to run a half marathon.And I did complete the Covered Bridges Half Marathon.I thought，“Now what？” I started to 5 a marathon. 5.A.report B.record C.recall D.consider √ 根据上文“Now what？”可推知，作者在完成了半程马拉松后开始寻找下一个目标，开始考虑全程的马拉松比赛。故选D。 解析 It so happened that I 6 a meeting one night and listened to the speaker and coach，Rick Muhr，and was so 7 by his words. 6.A.held B.missed C.attended D.mentioned 7.A.inspired B.disturbed C.embarrassed D.amused √ √ 6.根据下文“a meeting one night and listened to the speaker and coach”可知，作者参加了一个会议，听了演讲。故选C。 7.根据下文“I told him that I had signed up for the Ocean State Marathon，just a week away，and that I really didn’t believe I could .”可推知，作者深受教练Rick Muhr的话的鼓舞，所以才和他分享自己的担忧，希望得到鼓励。故选A。 解析 I told him that I had signed up for the Ocean State Marathon，just a week away，and that I really didn’t believe I could 8 .Rick locked eyes with me and said，“Trish，you’ve done enough training.You’ll finish！” 8.A.participate B.finish C.win D.run √ 根据下文教练Rick Muhr鼓舞的话“Trish，you’ve done enough training.You’ll finish！”可推知，作者怕自己无法完成马拉松比赛。故选B。 解析 I never had someone 9 me like that，let alone a real，live coach.He gave me the 10 I needed. 9.A.agree with B.rely on C.care for D.believe in 10.A.confidence B.pleasure C.satisfaction D.motivation √ √ 9.根据上文教练Rick Muhr的话“Trish，you’ve done enough training.You’ll finish！”可知，教练表达了对作者的信任。故选D。 10.根据上文“I told him that I had signed up for the Ocean State Marathon，just a week away，and that I really didn’t believe I could .”可知，作者对完成马拉松没有信心，所以教练Rick Muhr的鼓励给了她信心。故选A。 解析 I set out to run my 11 marathon and completed it in 4：25：00.Little did I know that this would be the beginning of nearly a decade of marathon and distance running. 11.A.last B.first C.only D.second √ 根据上文“And I did complete the Covered Bridges Half Marathon.I thought，‘Now what？’ I started to a marathon.”可知，这是作者第一次跑全程马拉松。故选B。 解析 Running a marathon isn’t for everybody.But it is for anybody，anybody who wants to 12 the unreachable and to take that 13 into the rest of their life. 12.A.test B.identify C.imagine D.reach 13.A.knowledge B.request C.principle D.experience √ √ 12.根据上文作者的经历可知，参加马拉松不是件容易的事情，结合句中“the unreachable”可知，作者把完成马拉松比喻成到达不可企及的高点。故选D。 13.作者讲完成马拉松相当于到达不可企及的高点，这是一种经历，一种可以铭记余生的经历。故选D。 解析 When you cross the finish line you may never have a 14 picture of what you are made of and capable of accomplishing.Your 15 of the world and，more importantly，of yourself will forever be changed! 14.A.bigger B.brighter C.clearer D.nicer 15.A.view B.love C.description D.memory √ √ 14.根据上文“who wants to the unreachable”可知，作者把完成马拉松比喻成到达不可企及的高点，结合句中“picture of what you are made of and capable of accomplishing”可推知，当冲过终点线时，你就突破了自己，会对自己有更清晰的认识。故选C。 15.根据上文“When you cross the finish line you may never have a picture of what you are made of and capable of accomplishing.”可知，冲过马拉松的终点意味着突破极限，会对自己有更清晰的认识，所以对世界和自己的看法将永远改变。故选A。 解析 返 回 本课结束 $
