W：Yes.It’s Pink and Say by Patricia Polacco.I read it last year and I read it with tears.It’s really worth reading. M：Is it a touching love story? W：No.It’s about two young Union soldiers.They become unlikely friends during the Civil War，experiencing physical wounds，heart-broken sacrifice，and the aching sadness of a beautiful friendship cruelly separated in a Confederate camp but never forgotten. M：I love reading such stories.So what else books did the author write? W：The Blessing Cup and Thank You，Mr Falker.Patricia Polacco writes from the heart，often drawing on family stories passed down through generations，such as in The Blessing Cup.She also tells her own moving story overcoming her difficulty in speaking in Thank You，Mr Falker. M：Do you have all the three books? W：Yes.I’ll go back and fetch them for you now.Oh，nice tea.Thank you for it. Text 10 W：What’s the attraction of coffee shops？It’s been said that J．K.Rowling wrote the Harry Potter books sitting in one in Edinburgh.But you’re spending all day buying one expensive coffee after another and haven’t sold your first novel yet；the cost can really add up.For those who work outside of a traditional office or just want to take time out，there’s a new alternative in London：a pay-per-minute cafe.You’ll be given a clock when you come in to keep time.When you leave，you return the item and pay the bill.The cost of hanging out，eating，working and meeting new people in the place is 3 pennies per minute or ￡1.80 an hour.Customers help themselves to coffee and cookies.They can also bring their own food to eat while accessing the Internet through Wi-Fi.The new coffee shop’s atmosphere is relaxing.The shop’s owner，Ivan Meetin，believes his coffee shop is a bit like “social media”，but with a face.Like-minded people go there to socialize.Some feel so much at home that they wash the dishes.The concept of coffee shops，where you pay for the time but not for the cup，has proved popular in Russia.Only time will tell if the British will warm to the idea. 第二部分　阅读(共两节，满分50分) 第一节　(共15 小题；每小题2.5分，满分 37.5分) 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 A The Best National Parks to Visit in Winter While most parks tend to draw families in the summer and fall，there are also ideal spots for adventurous winter trips. Yellowstone National Park，Wyoming The country’s oldest and best-known national park takes on an almost otherworldly atmosphere in winter：the air filled with rolling steam，the strong colors of hot springs，the surrounding white landscapes，let alone the impressive wildlife during this time，like bison，wolves，and playful red foxes.Just book a guided hiking tour to get a ranger’s perspective on the park and local people. Joshua Tree National Park，California With its giant red rocks and unique trees，you’ll feel like stepping onto a foreign planet as you spend hours hiking the Panorama Loop or Maze Loop.The park is recognized as an International Dark Sky Park，featuring virtually zero light pollution and the country’s best views of a starry sky. Grand Canyon National Park，Arizona A significantly lower number of visitors in winter mean you can take in unblocked views of the South Rim，and get to see the rare beauty of the Grand Canyon dusted with snow.For those adventurous and daring，it is recommended to hike the Bright Angel Trail and take the chance to see the canyon’s wintertime wildlife，including mule deer，elk，and bald eagles. Virgin Islands National Park，St.John Surprise！Not all wintertime national park trips need to involve snow.Virgin Islands National Park is most famous for its white-sand beaches.You can also hike inland to visit old sugar plantations，or venture out to the water to swim along with sea turtles and manta rays.You will definitely enjoy a different winter here. 21．Which park will one choose if he/she is interested in stars?

A．Hiking. B．Skiing. C．Swimming. D．Hunting. 答案　A 解析　细节理解题。根据Yellowstone National Park，Wyoming部分最后一句、Joshua Tree National Park，California部分第一句、Grand Canyon National Park，Arizona部分第二句和Virgin Islands National Park，St.John部分倒数第二句可知，所有的公园都提到了徒步旅行。故选A。 B It began the moment I sat down：An immediate sense of strong kinship(亲切感) with the people who chose to spend one week of their summer vacation in the Creative Writing Workshop at the University of Mississippi.I had been looking forward to bonding with some like-minded people.I wasn’t disappointed.I immediately hit it off with two other students，and we spent the rest of our week focusing on what had brought us together：a love of writing. Our instructors were two graduate students in the university，and the writing camp was strongly aimed at seeing what we could create from locating ourselves in new places.On the first day of the camp，we each were asked to choose a spot in the town square where we could write about our surroundings.We were told to focus on all of the senses but to prioritize hearing，taste，smell，and touch over sight.Throughout the week，we did similar exercises，finding inspiration in nature and in our own direct experiences. In the writing camp，I received encouragement from our instructors to publish and to get involved in the writing community.Learning about our instructors’ writing processes with their current projects and about their experiences of publishing helped us catch sight of what our writing lives might look like in the future.In fact，because they encouraged us to start publishing something I started sending my work out.My first short story will go to press early next month. My experience with the writing workshop was a big success，and I cannot recommend it highly enough.You will make lasting friendships there，be inspired by a green southern town with a literary history，and gain valuable writing experience.I hope this review will be helpful to those who are looking for a great writing workshop. 语篇解读　这是一篇记叙文。文章讲述了作者在Creative Writing Workshop的经历、收获和感受，作者对之极力推荐。 24．How did the author probably feel when she first met other students in the workshop? A．Nervous. B．Pleased. C．Proud. D．Disappointed. 答案　B 解析　推理判断题。根据第一段的“An immediate sense of strong kinship(亲切感) with the people who chose to spend one week of their summer vacation...”可推知，作者首次在工作坊里见到其他学生时感到很亲切、很高兴。故选B。 25．What is special about the writing camp? A．It has famous writers as instructors. B．It focuses on developing students’ imagination. C．It attaches more importance to the sense of sight. D．It asks students to write about surroundings using different senses. 答案　D 解析　细节理解题。根据第二段第二和第三句可知，写作营的特别之处是要求学生用不同的感官描写周围的环境。故选D。 26．What contributes most to the publication of the author’s short story? A．The pressure of her writing projects. B．The help from the writing community. C．The experiences as a graduate student. D．The encouragement from her instructors. 答案　D 解析　细节理解题。根据第三段最后两句可知，作者的短篇小说的发表要归功于导师的鼓励。故选D。 27．What is the main purpose of the passage? A．To give us tips on writing. B．To show her love for writing. C．To recommend the Creative Writing Workshop. D．To share her experiences at the University of Mississippi. 答案　C 解析　写作意图题。根据最后一段中“...I cannot recommend it highly enough.You will...I hope this review will be helpful to those who are looking for a great writing workshop.”可推知，文章的主要目的是推荐这家写作工作坊。故选C。 C The low percentage of women in science，technology，engineering，and mathematics(STEM) careers is often attributed(归因于) to men being believed to be better at the sort of thinking those fields require.Though studies have debunked the view，they have largely been based on results acquired from various several standardized tests.Now，researchers from Pennsylvania’s Carnegie Mellon University have found evidence that is hard to overlook：MRI(磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems. The groundbreaking study to evaluate the biological gender differences in the math talent of young children was led by the university’s professor of neuroscience，Jessica Cantlon.For their study，the team selected 104 young children，between 3 and 10 years old，divided almost equally by gender.The scientists used a functional MRI to observe their brain activity as they engaged in math tasks.These included watching age-appropriate educational videos and doing math exercises such as counting and addition，as well as reading for comparison. “We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks，compared to non-math content like reading or the alphabet，” Cantlon said.“When we do that in girls，we see a particular network of the brain respond，and when we do that same analysis in boys，we see the exact same regions.” So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions.Previous studies have indicated that parents tend to spend more time with young boys in play that inspires spatial cognition(空间认知) such as toys that involve learning number skills and shapes and solving puzzles.Educators were also observed to spend more time with boys during math class. 语篇解读　这是一篇说明文。研究表明，年轻男孩和女孩大脑中使用相同的机制和网络来解决数学问题，即解决数学问题的能力没有性别之分。 28．What does the underlined word “debunked” in paragraph 1 mean? A．Disproved. B．Supported. C．Confirmed. D．Overlooked. 答案　A 解析　词义猜测题。根据第一段第一句和最后一句以及画线词前的Though表示转折，可以推断出前后观点不一致，所以，研究结果驳斥了前面的观点。由此可知“debunked”的意思是“反驳”，与A项“证明……虚假”意义相近。故选A。 29．What does paragraph 2 mainly focus on? A．The purpose of the research. B．The process of the research. C．The participants of the research. D．The findings of the research. 答案　B 解析　段落大意题。根据第二段的内容可知，本段讲述了研究对象、研究方法、研究的内容等，所以第二段主要关注研究的过程。故选B。 30．What contributes to the lack of women in STEM careers? A．Mental capacity. B．Gender difference. C．Traditional prejudice. D．Family background. 答案　C 解析　细节理解题。根据第一段第一句和最后一段前两句可知，传统的偏见导致了STEM职业中缺少女性。故选C。 31．What can be a suitable title for the text? A．MRI—A Great Helper in Research B．Toys—Boosters for STEM Potential C．Boys and Girls：Equally Talented in Math D．STEM Careers：Calling for More Women 答案　C 解析　标题归纳题。文章第一段中的“young girls and boys use the same mechanisms and networks in the brain to solve math problems”是全文的主题句，后文解释了证明这一结论的研究过程以及对此结论的进一步分析。故选C。 D Electric cars are supposed to help the world go green and stop hurting the planet.Engineers at Brown University and the University of Maryland are taking that goal to another level，with a new idea for batteries made from trees，according to new findings published in Nature. Lithium-ion batteries(锂电池) have become the new form of rechargeable batteries thanks to their extraordinarily long charge.You’re probably reading this story from a device powered by such a battery.Most electric cars like ones made by Tesla use lithium-ion batteries. These batteries use a liquid solution that conducts lithium ions from the battery’s cathode and anode(阴极和阳极)，but the liquid is not what helps ensure electrical power goes from the battery to the device it’s powering.The problem is that this liquid is made of harmful materials that are sometimes unstable.They sometimes have explosive results.A solid conducting structure would prevent this from happening，but it could be likely to crack and break，making the battery useless. An ideal material for solid state lithium-ion batteries would be thin and flexible to resist structural stresses，and it is wood from a tree.The team in charge of the new research developed a mixed material made of copper(铜) and fibers coming from wood.They tested it out as a model for conducting ions back and forth in a lithium-ion battery，and found it works 10 to 100 times better than other solid-state conductors—a record high. The new findings are just based on basic model tests，and a rechargeable battery made of trees is still quite a way off.But if it passes test as a practical form of energy，it can very well replace current rechargeable batteries.It is not hard to imagine electric cars having better sales for their real green，but saying that their batteries are just made from trees is beyond our imagination. 32．How are engineers making electric cars greener according to the text? A．By improving the materials of batteries. B．By reducing lithium ions in the batteries. C．By using liquid to conduct electric power. D．By producing more lithium-ion batteries. 答案　A 解析　细节理解题。根据第一段可知，工程师们通过用树木来制造新电池(即改进电池材料)的方式来使得电动汽车更环保，故选A。 33．What is the advantage of lithium-ion batteries? A．They contain eco-friendly liquid. B．They offer electrical power stably. C．Their charge lasts for a long time. D．They are safe and unlikely to explode. 答案　C 解析　细节理解题。根据第二段第一句可知，锂电池成为一种新型的充电电池的优势在于它的供电时间长，故选C。 34．Why is wood chosen as the solid-state conductor? A．It is resistant to structural pressures. B．It is much thicker and less changeable. C．Its copper and fibers conduct ions well. D．It proves to be a practical form of energy. 答案　A 解析　细节理解题。根据倒数第二段第一句可知，树木被选作固态导体是因为它能对抗结构应力，故选A。 35．What can we infer about batteries made of trees from the last paragraph? A．They have taken effect for a long time. B．They are still being tested at present. C．They will never replace current batteries. D．They will make electric cars hard to sell. 答案　B 解析　推理判断题。根据最后一段第一句可知，以树为材料的电池目前还只是在其模型测试阶段，故选B。 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。 Think back to the last time you shopped for fruits and vegetables.You may have noticed some items labelled with the word “organic”． 36 “Organic” refers to the way food is grown.To be labelled as organic，food production must meet strict guidelines.These can be different depending on where you live.In the United States，organic food must be grown or raised without using pesticides or chemical fertilizers. 37 That changed after the Industrial Revolution.During the 20th century，many ideas that were used by factories and big businesses were put into action on farms.This helped some farms grow larger and produce more. The organic movement was started to get back to the old traditional ways of farming.Why? Many believe the chemicals and pesticides used in modern farming can be harmful to your health. 38 And those who support the organic movement also point to its benefits for the environment. Have you ever compared organic and non-organic foods at the grocery store? If so，you know that organic food tends to cost more.This happens for many reasons.Organic farming produces fewer crops. 39 Additionally，organic farms spend more money taking care of the animals they raise.These and other factors drive the cost of organic food up. Is organic food worth the extra cost? Some people believe it is.They may think it tastes better or just prefer to eat food that has not been grown using chemicals. 40 They are still trying to find a major difference between organic and non-organic foods in terms of safety，nutrition，or taste.Still，others argue that the environmental benefits of organic food make it worth the price. A．Have you ever wondered what that means? B．The cost of production is also usually higher. C．For most of history，almost all food was organic. D．Are you wondering if organic food is right for you? E．Many people are willing to pay more for organic food. F．Some also think organic food is naturally more nutritious. G．Scientists have studied organic and non-organic foods for many years now. 36．答案　A 解析　空前一句提到了“organic”一词，下一句解释其含义，由此可知，空处应该是提出“有机”是什么意思，所以A项承上启下。故选A。 37．答案　C 解析　空后说到工业革命之后情况变了，农业也开始用工业理念，由此可知，空处应是说明工业革命前的情况。所以C项“历史上大多数时期，所有食物都是有机的”符合语境。故选C。 38．答案　F 解析　前后内容都是采用传统农业模式的有机运动又重新启动的原因，空处也是说明原因并强调有机农业的好处。故选F。 39．答案　B 解析　根据上下文可知，此处在分析有机食品往往价格更高的原因，B项承接上文，也是有机食品价格高的一个原因。故选B。 40．答案　G 解析　根据空后一句可知，G选项“科学家们已经研究有机和非有机食品很多年了”能够引起下文，G项的“Scientists”就对应后文中的“They”。故选G。 第三部分　语言运用(共两节，满分30分) 第一节　(共15 小题；每小题1分，满分 15 分) 阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Rene Compean was no stranger to Angeles National Forest.But after challenging a(n) 41 path last April，the 45-year-old mechanic was lost.

All Compean could do then was wait and 46 .The temperature was dropping fast.After 47 two mountain lions and a bear，he kept a big stick and some 48 rocks beside him in case an animal came close. Kuo，then 47，works in the tech industry，and always loves 49 where photos are taken.When he saw the 50 of Compean’s legs released on the Twitter，he pulled up a satellite map.He 51 his search to the surrounding area after knowing Compean’s car was parked near Buckhorn Campground.After comparing it to the satellite map，Kuo 52 something：“He’s got to be on the south side because there’s not really any 53 valleys on the north side.” That finding tightened his search，and finally the 54 matched！Soon，Compean was saved. Compean’s story probably would have ended very differently，if a 55 with strong satellite skills and a sharp eye for detail had not taken action. 语篇解读　本文是一篇记叙文。本文讲述Rene Compean在洛杉矶国家森林公园迷路后得到好心陌生人的帮助最后得救的故事。 41．A.attractive B．new C．smooth D．natural 答案　B 解析　根据上文“Rene Compean was no stranger to Angeles National Forest.”可知，Rene Compean对洛杉矶国家森林公园并不陌生，但是他还是迷路了，可以推测他是挑战了新的线路。故选B。 42．A.shock B．confusion C．fear D．excitement 答案　C 解析　根据第三段中“After two mountain lions and a bear...in case an animal came close.”可知，晚上丛林中很危险，所以Compean开始害怕起来。故选C。 43．A.signal B．chocolate C．light D．iron 答案　A 解析　根据下文中“he texted the police”可推测，他是爬到了一处有信号的地点，此处“one bar of”是指“一格”，常用于指手机信号。故选A。 44．A.function B．rest C．break D．die 答案　D 解析　die死机，电量耗尽。前文提到信号只有一格，而且徒步了一天，手机很有可能是快没电了，下一段的“All Compean could do then was wait”也印证了这一点。故选D。 45．A.text B．video C．shot D．record 答案　C 解析　根据上文“attaching a photo showing where he was”中的photo可知，此处也表示“照片”，shot作名词时有该意义。故选C。 46．A.sleep B．hope C．stare D．reflect 答案　B 解析　根据上文可知，Compean在向警察求助后手机没电了，自己又迷路了，所以只能默默等待，希望警察尽快找到自己。故选B。 47．A.catching B．fighting C．hunting D．spotting 答案　D 解析　根据后文“he kept a big stick and some rocks beside him in case an animal came close”可知，Compean是远远地看见了这些野兽，想要尽量保护自己。故选D。 48．A.sharp B．shiny C．clean D．flat 答案　A 解析　根据上文可知，Compean看到了狮子和熊这类凶猛的野兽，为了防止它们接近自己肯定会将锋利的石头放在身边，sharp意为“锋利的”，符合常识。故选A。 49．A.going about B．talking about C．leaving for D．looking for 答案　D 解析　go about着手做；talk about谈论；leave for去往；look for寻找。根据后文“he pulled up a satellite map”可知，Kuo喜欢寻找照片的拍摄地。故选D。 50．A.image B．injury C．cut D．number 答案　A 解析　根据前文可知，Compean趁着手机还有信号给警察发了一张图片，图片上显示他的腿被石头和植物包围，所以Kuo看到的是他的腿的图片。上文的photo和shot与image是同义词复现。故选A。 51．A.changed B．counted C．narrowed D．added 答案　C 解析　根据下文“after knowing Compean’s car was parked near Buckhorn Campground”可知，Kuo在这之后把搜索范围缩小到附近区域。故选C。 52．A.realized B．admitted C．recalled D．imagined 答案　A 解析　根据后文“He’s got to be on the south side because there’s not really any valleys on the north side.”可知，Kuo在对比地图后，得出了合理的结论，所以是“意识到”这件事。故选A。 53．A.bare B．green C．deep D．dangerous 答案　B 解析　根据第二段的“The showed his legs surrounded by an endless landscape of rocks and plants.”可知，Compean的位置旁边是无尽的绿植，Kuo是据此排查的。故选B。 54．A.figures B．actions C．locations D．measures 答案　C 解析　结合文意可知，Kuo一直在缩小搜索范围，想要找到Compean的位置，由句中finally可知是匹配到了迷路的地点。故选C。 55．A.detective B．policeman C．hiker D．stranger 答案　D 解析　根据全文可知，Kuo只是一个喜欢寻找照片拍摄地点的科技工作人员，对于Compean来说是一个陌生人。故选D。 第二节　(共10 小题；每小题1.5 分，满分 15 分) 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 A recommendation to drink eight glasses of water a day has become accepted wisdom and often appears in health guidance.A latest study，however，reveals that people have 56.____________wide range of water intakes.Many people only require about 1.5 to 1.8 litres a day,57. (low) than the two litres typically recommended. “The current recommendation is not supported 58.

Some people argue that cloning should be encouraged because it can speed up the development of science and bring us into a new age of progress.However，some people hold that cloning technology has many problems at present，and that the misuse of it may lead to unimaginable consequences.Therefore，we must be careful to make appropriate use of it.In this case it could bring us a lot of benefits；otherwise，we may end up suffering because of it. 第二节　(满分25分) 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 I was in my room，unwilling to head to the community theatre with “my brother” Henry.He was just adopted by my parents recently.I was not in the mood for being onstage with him. “Kristie，come here，” my mom called.Following her voice，I found her outside the bathroom，holding a wet book.She gave the book a shake.“Henry’s book was in the bathtub.Did you put it there？” She glared at me—something she never did before Henry came to our home.I didn’t wet his book on purpose.Tears of hurt clouded my eyes.Worse still，she promised to buy him a new copy.My heart ached.Henry was stealing my mother’s love.He was ruining my life. Meanwhile，Henry was just nearby，absorbed in working on a complicated rope knot(绳结) as usual.Why did a boy like him do the girly work? Far from manly! Soon，it was time to have to set off for the community theatre.As Henry walked ahead of us to the car，my mom took me aside and said in a low voice，“It’s the first time for Henry to be onstage.Be kind to him，Honey.” I nodded but sighed.Being kind didn’t use to be hard.But after Henry moved in，everything felt different.The theatre used to be a special place for my parents and me.With Henry involved，it didn’t seem so special any more. Finally，it was our stage time.My heart beat wildly.I forgot my annoyance at Henry for a while.As we kids lined up，ready to act out our short play，I realized how loosely I had tied the drawstring(束带) on my skirt.Sure enough，my skirt began to drop.Laughter from the audience could be heard，and even though I was wearing shorts under my skirt，I could feel my face burst into flames.However，my hands were full.If only someone could help me out! 注意：续写词数应为 150 左右。 Right then，Henry sensed my embarrassment. After the performance，I found Henry and tapped him on the arm gratefully. 参考范文 Right then，Henry sensed my embarrassment.He immediately came to my aid.He pulled up my skirt and skillfully tied the drawstring with a beautiful knot.When I saw what Henry did for me，something deep in my mind began to change.It seemed as if my cold heart began to melt slowly and my annoyance at him gradually gave way to guilt.I regretted having treated him as a stranger.While my mind was wandering，our performance time came.It turned out a great success，thunderous applause filling the whole theatre. After the performance，I found Henry and tapped him on the arm gratefully.“Thanks，” I said with a grateful smile on my face.I had to admit that but for his timely help，I would have been extremely embarrassed.Without his knotting skill，the performance would have been quite different.“KNOT a problem.You are my sister，” he grinned innocently，saying humorously.Surrounded by the cheerful atmosphere，I felt a flood of warmth of a big family.Maybe it wouldn’t be so bad to have a new person in my corner of the world after all. 学科网（北京）股份有限公司 $$null
