AIt’s no secret that your personal characteristics directly a ffect how you interact with the world-but you might be surprised at just how deep it goes. Experts think that your personality can even affect how you exercise and influence what sports are suitable for you.Highly SensitiveHighly sensitive people may be more uncomfortable with group exercise classes or team sports where they feel their every move is being observed. Additionally, they may feel more upset over an ineffective or poor workout, says researcher Elaine Aron.For such people, individual or non- competitive activities like biking, running and hiking are ideal.Type A PersonalityType A individuals often have an “all or nothing approach”to exercise. This personality type is known for sticking closely to their plan, not to mention being super competitive. However, this can cause them to stick too closely to a fitness routine, which means they might try to push past an injury.To get better exercise results, Type A people need to be aware that following an exercise plan too strictly may limit their progress. They should be more flexible and listen to their body, especially when they are in pain.Type B PersonalityThis laid-back group may get too lazy about their exercise plan, which prevents them from seeing results. They are often less willing to devote enough time and energy to their fitness goals, especially if exercise is something that makes them anxiousType B individuals succeed in creative and co-operative environments, so team sports and group gym classes may be perfect.Remember, there are plenty of ways you can adapt a fitness plan to suit your needs, regardless of your characteristics. Just keep in mind what you like.21. Why might highly sensitive people be unwilling to take part in group sports?A. They will feel like they are being evaluated.B. They don't like socialising with other people.C. They don't consider themselves to be athletic.D. They fear they'll be let down by their teammates.22. Type A personalities can be best described asA. committed B flexible C independent D. sensitive23. What is the purpose of the text?A. To help people understand what personality type they areB. To explain how personal characteristics affect exercise habitsC. To identify the dangers of doing the wrong type of exerciseD. To describe different types of workouts that are available todayBAt first sight, Alma Deutscher, a twelve-year-old girl from England appears to be like any other typical pre-teen. She loves to skip rope, read and play with her younger sister. But this modest youngster, who composed her first musical work at age six, first short opera at age seven, and first full-length opera based on Cinderella at age ten, is anything but average. Though her parents downplay her extraordinary talent, young Alma is being described as “little Mozart” by the music worldAlma’s operatic take on the classic fairy tale, which she began writing at age eight, has a slight twist. Her Cinderella is a musician who meets her Prince Charming through a song. “In my Cinderella, she sings the beginning of a ballad --- but at midnight she flees. Eventually, the prince finds her after asking all the maidens of the land to sing the end of the bal lad.”The opera was first performed in Vienna, Australia on December 29, 2016, where the then eleven-year-old skillfully switched between the piano and the violin and receives enthusiastic reviews. The young genius has since performed two new piano works, once in Australia and the other in China.While this may appear to be a lot for someone so young, Alma is not worried. She says, “Of course I have to work hard. But all children have to work hard for exams, and at least when I work hard, I work hard for something incredibly exciting, like seeing my whole opera put on stage.Alma’s musical talent first came to light before she could even talk. Her parents recall that as an 18-month-old toddler, she was able to hum a pitch perfect version of the children’s rh yme Twinkle Twinkle Little Star.However, Alma’s abilities only gained international attention in 2012, after a family friend posted a video online comparing her to Mozart. The family was suddenly swamped with media requested and Alma became an overnight star, dubbed “little Mozart”. This nickname makes her parents unhappy because they believe itputs added pressure on the young girl. They would instead prefer her to be called “a composer and musician”.Alma does not want to be compared to the famous artist either, saying, “There was only one Mozart, and I prefer to be little Alma.” Regardless of what she calls herself, the twelve-year-old is changing the world of music forever!24. What do we know about Alma Deutscher?A. She comes from a famous musical family.B. She has shown great musical talent from a young age.C. She regularly performs the classical music of Mozart.D. She has adapted some famous works of classical music.25. How did Alma get to be widely known?A. Through an online videoB. By performing on televisionC. By putting on an operaD. Through her parents’ promotion26. What is Alma’s attitude towards her success?A. She is still unsatisfied with her performance.B. She is uncomfortable with so much pressure.C. She is modest about her musical achievementsD. She is proud to have become a professional musician.27. What can we infer about Alma’s parents?A. They are very well-educated people.B. They are protective of their daughter.C. They have pushed Alma to take up music.D. They have made a good life plan for Alma.CThe belief that new technologies are causing the death of work is the idea that never goes away. Despite evidence to the contrary, we still view technological change today as being more rapid and dramatic in its consequences for work than ever before.But this is nothing new. People have always viewed the technological changes that take place during their lives as the most dramatic and dangerous that ever happened in history.In the 1930s, the British economist(经济学家) John Maynard Keynes predicted the widespread use of electricity would produce a world where people spend most of their time doing nothing. In the United States during the 1960s, the government repeatedly investigates fears that automatic machines would permanently reduce the amount of work available. In 1988, one Australian historian claimed that at least a quarter of the workforce would be without jobs within 10 years because of computers.Of course, none of these disasters came to pass in the United Kingdom, the United States and Australia, or anywhere else.Yet today, we are seeing the return of these predictions, with some experts claiming the world of work is once more undergoing radical and unprecedented change. They argue that robots and other workplace technologies are causing a reduction in the total amount of work available, or are bringing a more rapid pace of substitution of machines for humans than has been seen previously.But there is a little evidence to support such beliefs. Statistics show that the percentage of people in work, the number of hours they work, and how frequently they change jobs have remained remarkably constant over the past 20 years.This stability should not come as a surprise. There are good reasons why we should not expect new technologies to cause the death of work. New technologies always cause job losses, but that is only part of the story. What also needs to be understood is how they increase the amount of work available.One way this happens is through the increases in incomes that accompany the use of new technologies. With the introduction of these technologies, good and services can be produced faster, which results in higher real incomes for workers. Higher incomes then increase demand for other products and consequently more workers are needed to make them. Additionally, while new technologies are likely to substitute for some types of workers, they will also increase demand for other types of workers, especially those with higher level skills and expertise.So, the end of work is no closer today than at any time in the past. But there is still a need to keep disproving the prediction, to reduce people's fears.28. What is the function of the second paragraph?A. To explain the importance of developing new technology.B. To show how technology affected employment in the past.C. To argue that technological dangers are becoming more serious.D. To give historical examples of unnecessary fear about new technology.29. How can employment statistics over the past 20 years best be described?A. ConfusingB. ReliableC. StableD. Variable30. According to paragraph 7, why does demand for products often increase after new technology is introduced?A. There are more goods for people to choose from.B. There is more demand for new skills in the economy.C. Productivity improvements help raise workers’ salaries.D. Higher quality goods at lower prices encourage consumption.31. What is the author’s opinion about the introduction of new technology?A. It does not have an effect on most people’s jobs.B. Its benefits are usually not worth the introduction.C. It usually leads to a significant increase in employment.D. Its danger to peoples employment possibilities is overstated.DSupermarket shelves are filled with plant-based alternatives to cow milk, including soy, nut, and coconut milk. These products are popular with consumers who cannot drink cows’ milk for health reasons, as well as with those concerned about animal welfare and environmental sustainability. While the dairy-free(非乳制的) options work well with cereal or in coffee, they fail miserably when it comes to making milk-based products like cheese or yogurt. However, these shortcomings may soon be a thing of the past, thanks to a new company in California, which has figured out how to create animal-free milk in a laboratory!Perumal Gandhi and Ryan Pandya founded the company in 2014 after becoming increasingly annoyed with the lack of cows’ milk-free alternatives, particularly for cheese. For Gandhi, who stopped consuming animal products five years earlier due to environmental and animal welfare concerns, the motivation to create a better alternative stemmed from his love of cheesy pizza. Pandya was spurred into taking action after being forced to eat some “really bad” dairy-free cream cheese on his sandwichThe two MIT biomedical engineering scientists decided to join forces to create a more realistic alternative to dairy-based products. In their university lab, the pair spent nine months first isolating cow DNA then inserting it into yeast(酵母). This genetic modification enabled the yeast to produce the necessary milk proteins. The final step of the process involved mixing the proteins with some plant nutrients and fats.The dairy-free milk not only tastes like the real thing but is also healthier, has a longer shelf life and, most important of all, is Earth friendly. According to the company’s website, when compared to conventional milk production, their process uses 65% less energy, creates 84%o less greenhouse gas emissions and requires 91% less land and an amazing 98% less water! Best of all, since it contains real milk proteins, the product behaves like the cow-produced version, which means vegetarian consumers will no longer have to deal with soggy cheese on their sandwiches and pizzas.The company plans to bring their creation to market later this year and their first product will most likely be cheese since there are already numerous good cows’ milk alternatives available to consumers.32. The underlined word "those" in paragraph 1 refers to_______.A. alternativesB. peopleC. productsD. reasons33. The company s founders were motivated to make the new product because of_______.A. their deep concern for the environmentB. their worry that farm animals were poorly treatedC the over-consumption of the dairy-based productsD. the poor taste of dairy-free cheese presently available34. What can be inferred from paragraph 4?A. The dairy-free products cannot be stored for a long time.B. The new products will taste better than dairy-based ones.C. Cow farming causes considerable environmental damage.D. The dairy-free milk will be more expensive than cow’s milk.35. Which of the following can be the best title for the text?A. Healthier CheeseB. New Milk Saves PlanetC. Fresher Milk, Better FutureD. Making Milk without Cows第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

(2)以食品研究为中心的大学和科研机构众多，科技力量雄厚；位于波罗的海航运要冲，地理位置优越；海陆空交通发达，利于产品销往世界；接近经济发达的西欧，市场广大；欧盟产业集聚等政策。
（每点2分，4点共8分）(3)食品谷以科技创新为驱动，引领世界食品潮流和发展，通过产研结合，使传统食品产业升级、转型，并走向集聚。
启示：科技创新驱动、产研结合、升级转型、集群发展（每点2分，3点共6分）。
37. (24分)(1)夜间强，白昼弱（2分）；子夜前后最强，正午前后最弱（2分）。
(2)正午前后，太阳辐射最强烈，城市中心地表和建筑物大量吸收太阳热量，大气对流、湍流作用增强，利于散热；城市与郊区热力环流加强，城区和郊区大气在水平和垂直方向上的混合作用增强，城郊温差减少；城市上空盛行上升气流利于散热；而郊区盛行下沉气流增温且不利于散热。
因而引起城区气温低于郊区气温的“冷岛”效应。
（每点2分，3点共6分）(3)规律：冬季最强，夏季最弱，春秋居中。
（2分）理由：冬季受冷气团控制，天气稳定，有利于热岛的形成与发展；受山谷地形影响，冬季逆温层加厚，不利于城市散热；冬季正值供暖期，排放热量多；冬季取暖燃煤污染物排放量大，使得城区大气逆辐射增强，收入热量多。
（每点2分，3点共6分）(4)兰州城市化的发展改变了下垫面的热力属性，人工建筑物吸热快而热容量小；城市地面和建筑物对太阳辐射反射率较低，吸收率加大；城区密集的建筑群、纵横的道路桥梁，构成较为粗糙的城市下垫面、因而对风的阻力增大，风速降低，热量不易散失；城市化发展使城市绿地和水体减少，地表含水量少，热量更多地以显热形式进入空气中，导致空气升温，使城市热岛效应不断增强。

一、现代文阅读（35分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成1—3题。
人们在学习中能否掌握正确的阅读方法以获得理想的效果，是一个非常重要的问题。
在人生的不同阶段，学习目标不同，采取的阅读模式也不同。
大体而言，阅读模式有知识型阅读与研究型阅读两种。
研究型阅读主要有以下三种方式：一是疑问式阅读。
在知识型阅读阶段，读者往往将自己所阅读的著作视为权威的看法与正确的结论，很少对它们提出疑问，对经典的作品与权威人士的著作就更是如此。
但是在研究型阅读中就大不相同，怀疑是读者面对所有著作应该持有的态度。
疑问式的阅读对于研究能力的培养是至关重要的，因为所有的学术研究不外乎发现问题与解决问题，而发现问题又是解决问题的前提，而具有质疑的眼光又是发现问题的前提，可以说提出疑问是所有人在学术上取得进展的基础。
提出的疑问如果一时解决不了，最好的做法就是先将它存起来，等遇到坚实的证据时再解决。
脑子中有一批问题储存着，这本身就是一笔巨大的学术财富。
二是对比式阅读。
在知识型阅读阶段，由于要追求知识的准确性与可靠性，读者就必须精心挑选阅读的对象，并将其作为权威的说法加以记忆，从而构成自己稳定的知识谱系。
但是这种阅读习惯也容易形成盲从的缺陷。

AIt’s no secret that your personal characteristics directly a ffect how you interact with the world-but you might be surprised at just how deep it goes. Experts think that your personality can even affect how you exercise and influence what sports are suitable for you.Highly SensitiveHighly sensitive people may be more uncomfortable with group exercise classes or team sports where they feel their every move is being observed. Additionally, they may feel more upset over an ineffective or poor workout, says researcher Elaine Aron.For such people, individual or non- competitive activities like biking, running and hiking are ideal.Type A PersonalityType A individuals often have an “all or nothing approach” to exercise. This personality type isknown for sticking closely to their plan, not to mention being super competitive. However, this can cause them to stick too closely to a fitness routine, which means they might try to push past an injury.To get better exercise results, Type A people need to be aware that following an exercise plan too strictly may limit their progress. They should be more flexible and listen to their body, especially when they are in pain.Type B PersonalityThis laid-back group may get too lazy about their exercise plan, which prevents them from seeing results. They are often less willing to devote enough time and energy to their fitness goals, especially if exercise is something that makes them anxiousType B individuals succeed in creative and co-operative environments, so team sports and group gym classes may be perfect.Remember, there are plenty of ways you can adapt a fitness plan to suit your needs, regardless of your characteristics. Just keep in mind what you like.21. Why might highly sensitive people be unwilling to take part in group sports?A. They will feel like they are being evaluated.B. They don't like socialising with other people.C. They don't consider themselves to be athletic.D. They fear they'll be let down by their teammates.22. Type A personalities can be best described as ___________.A. committed B flexible C independent D. sensitive23. What is the purpose of the text?A. To help people understand what personality type they areB. To explain how personal characteristics affect exercise habitsC. To identify the dangers of doing the wrong type of exerciseD. To describe different types of workouts that are available todayBAt first sight, Alma Deutscher, a twelve-year-old girl from England appears to be like any other typical pre-teen. She loves to skip rope, read and play with her younger sister. But this modest youngster, who composed her first musical work at age six, first short opera at age seven, and first full-length opera based on Cinderella at age ten, is anything but average. Though her parents downplay her extraordinary talent, young Alma is being described as “little Mozart” by the music worldAlma’s operatic take on the classic fairy tale, which she began writing at age eight, has a slight twist. Her Cinderella is a musician who meets her Prince Charming through a song. “I n my Cinderella, she sings the beginning of a ballad --- but at midnight she flees. Eventually, the prince finds her after asking all the maidens of the land to sing the end of the ballad.”The opera was first performed in Vienna, Australia on December 29, 2016, where the then eleven-year-old skillfully switched between the piano and the violin and receives enthusiastic reviews. The young genius has since performed two new piano works, one in Australia and the other in China.While this may appear to be a lot for someone so young, Alma is not worried. She says, “Of course I have to work hard. But all children have to work hard for exams, and at least when I work hard, I work hard for something incredibly exciting, like seeing my whole opera put on stage.Alma’s musical talent first came to light before she could even talk. Her parents recall that as an 18-month-old toddler, she was able to hum a pitch perfect version of the children’s rhyme Twinkle Twinkle Little Star.However, Alma’s abilities only gained international attention in 2012, after a family friend posted a video online comparing her to Mozart. The family was suddenly swamped with media requested and Alma became an overnight star, dubbed “little Mozart”. This nickname makes her parents unhappy because they believe it puts added pressure on the young girl. They would instead prefer her to be called “a composer and musician”.Alma does not want to be compared to the famous artist either, saying, “There was only one Mozart, and I prefer to be little Alma.” Regardless of what she calls herself, the twelve-year-old is changing the world of music forever!24. What do we know about Alma Deutscher?A. She comes from a famous musical family.B. She has shown great musical talent from a young age.C. She regularly performs the classical music of Mozart.D. She has adapted some famous works of classical music.25. How did Alma get to be widely known?A. Through an online videoB. By performing on televisionC. By putting on an operaD. Through her parents’ promotion26. What is Alma’s attitude towards her success?A. She is still unsatisfied with her performance.B. She is uncomfortable with so much pressure.C. She is modest about her musical achievements.D. She is proud to have become a professional musician.27. What can we infer about Alma’s parents?A. They are very well-educated people.B. They are protective of their daughter.C. They have pushed Alma to take up music.D. They have made a good life plan for Alma.CThe belief that new technologies are causing the death of work is the idea that never goes away. Despite evidence to the contrary, we still view technological change today as being more rapid and dramatic in its consequences for work than ever before. But this is nothing new. People have always viewed the technological changes that take place during their lives as the most dramatic and dangerous that ever happened in history.In the 1930s, the British economist(经济学家) John Maynard Keynes predicted the widespread use of electricity would produce a world where people spend most of their time doing nothing. In the United States during the 1960s, the government repeatedly investigates fears that automatic machines would permanently reduce the amount of work available. In 1988, one Australian historian claimed that at least a quarter of the workforce would be without jobs within 10 years because ofcomputers.Of course, none of these disasters came to pass in the United Kingdom, the United States and Australia, or anywhere else.Yet today, we are seeing the return of these predictions, with some experts claiming the world of work is once more undergoing radical and unprecedented change. They argue that robots and other workplace technologies are causing a reduction in the total amount of work available, or are bringing a more rapid pace of substitution of machines for humans than has been seen previously.But there is a little evidence to support such beliefs. Statistics show that the percentage of people in work, the number of hours they work, and how frequently they change jobs have remained remarkably constant over the past 20 years.This stability should not come as a surprise. There are good reasons why we should not expect new technologies to cause the death of work. New technologies always cause job losses, but that is only part of the story. What also needs to be understood is how they increase the amount of work available.One way this happens is through the increases in incomes that accompany the use of new technologies. With the introduction of these technologies, good and services can be produced faster, which results in higher real incomes for workers. Higher incomes then increase demand for other products and consequently more workers are needed to make them. Additionally, while new technologies are likely to substitute for some types of workers, they will also increase demand for other types of workers, especially those with higher level skills and expertise.So, the end of work is no closer today than at any time in the past. But there is still a need to keep disproving the prediction, to reduce people's fears.28. What is the function of the second paragraph?A. To explain the importance of developing new technology.B. To show how technology affected employment in the past.C. To argue that technological dangers are becoming more serious.D. To give historical examples of unnecessary fear about new technology.29. How can employment statistics over the past 20 years best be described?A. ConfusingB. ReliableC. StableD. Variable30. According to paragraph 7, why does demand for products often increase after new technology is introduced?A. There are more goods for people to choose from.B. There is more demand for new skills in the economy.C. Productivity improvements help raise workers’ salaries.D. Higher quality goods at lower prices encourage consumption.31. What is the author’s opinion about the introduction of new technology?A. It does not have an effect on most people’s jobs.B. Its benefits are usually not worth the introduction.C. It usually leads to a significant increase in employment.D. Its danger to peoples employment possibilities is overstated.DSupermarket shelves are filled with plant-based alternatives to cow milk, including soy, nut, and coconut milk. These products are popular with consumers who cannot drink cows’ milk for health reasons, as well as with those concerned about animal welfare and environmental sustainability. While the dairy-free(非乳制的) options work well with cereal or in coffee, they fail miserably when it comes to making milk-based products like cheese or yogurt. However, these shortcomings may soon be a thing of the past, thanks to a new company in California, which has figured out how to create animal-free milk in a laboratory!Perumal Gandhi and Ryan Pandya founded the company in 2014 after becoming increasingly annoyed with the lack of cows’milk-free alternatives, particularly for cheese. For Gandhi, who stopped consuming animal products five years earlier due to environmental and animal welfare concerns, the motivation to create a better alternative stemmed from his love of cheesy pizza. Pandya was spurred into taking action after being forced to eat some “really bad” dairy-free cream cheese on his sandwich.The two MIT biomedical engineering scientists decided to join forces to create a more realistic alternative to dairy-based products. In their university lab, the pair spent nine months first isolating cow DNA then inserting it into yeast(酵母). This genetic modification enabled the yeast to produce the necessary milk proteins. The final step of the process involved mixing the proteins with someplant nutrients and fats.The dairy-free milk not only tastes like the real thing but is also healthier, has a longer shelf life and, most important of all, is Earth friendly. According to the company’s website, when compared to conventional milk production, their process uses 65% less energy, creates 84% less greenhouse gas emissions and requires 91% less land and an amazing 98% less water! Best of all, since it contains real milk proteins, the product behaves like the cow-produced version, which means vegetarian consumers will no longer have to deal with soggy cheese on their sandwiches and pizzas.The company plans to bring their creation to market later this year and their first product will most likely be cheese since there are already numerous good cows’milk alternatives available to consumers.32.
