Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly where she’s been during her worldwide vacation in a special way.
The traveler, who was born with a bone disease, had her right leg amputated(截肢) at the age of four. Although the amputation caused setbacks for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.
To spread that message, Gallagher has taken to social media, where she shares photos of her travels across the globe, but instead of simply using a geo-tag, she writes her location across her artificial leg before taking a picture.
Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam, relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking spectacular pictures in Athens and enjoying a river cruise in
Budapest, all with the well-known locations written on her artificial leg.
“I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalkboard，” Gallagher said. “My mum and grandmother weren’t too keen on the idea, but my friends thought it was great and told me to go for it, s o I did.”
Gallagher said people often stare when she’s writing on her leg, but once she shares the photos, she receives only positive feedback. “My leg hasn’t stopped me from doing anything I’ve wanted to do,” she said. “I don’t know if it’s my determinati on to prove to myself that I can do it, but regardless, I’ve been able to keep up with my peers and lead a pretty great life.”
Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.
24．What message did Gallagher want to spread in her special way?
A．She enjoys her traveling across the globe.
B．She suffers little from her leg amputation.
C．She looks on her misfortune as another form of blessing.
D．She has exactly fallen in love with posting photos online.
25．What does the underlined word “which” in Paragraph 4 refer to?
A．The Continent.B．The pictures.
C．The leg. D．The locations.
26．Gallagher can best be described as ________．
A．helpful and ambitious B．friendly and generous
C．determined and creative D．independent and sensible 27．Which of the following might be the best title for the text?
A．Never Too Late to Share B．A Special Artificial Leg
C．An Outstanding Photographer D．Gallagher’s Summer Holidays
C
Most of the new diseases we humans have faced in the past several decades have come from animals. The more we come into contact with wild animals, the more we risk a so-called disease “spillover” from animals to humans.
“As people move and wildlife move in respon se to a changing environment, humans
and wildlife and animals will come in contact more regularly,” said Jeanne Fair from the Los Alamos National Laboratory in New Mexico. Fair argues that by shifting animal habitats, climate change will also make the opportunities for disease spillover more frequent. “Everything is sort of shifting and will shift into the future as the environment changes through climate change,” Fair said.
Scientists, including climatologists and epidemiologists on Fair’s team at Los Ala mos, are beginning to model how changes to the climate will impact the spread of infectious diseases. It’s early days for this kind of research, but previous studies suggest that extreme weather has already played a role in at least one outbreak. Scientists say drought and deforestation have combined to force bats out of rainforests and into orchards（果园）in Malaysia to find food. Those bats, a common disease reservoir, then passed the Nipah virus through pigs to humans for the first time in the late 1990s.
“We’re going by the past data to really predict what’s going to happen in the future,” Fair said, “And so, anytime you increase that wildlife-human interface, that’s sort of an emerging disease hot spot. And so, that’s just increasing as we go forward.”
Jef frey Shaman, head of the climate and health program at Columbia University’s public health school, argues we don’t yet know whether climate change will cause a net increase in infectious disease rates globally. For example, mosquitoes carry disease that affects millions of people across the world every year. As their habitats expand in some parts of the world, they might contract diseases elsewhere. Shaman says what we know for certain about climate change is that it will make it harder to predict where disease outbreaks will pop up.
28. How does climate change affect the spread of disease according to Fair?
A. By breaking animals’ habits.
B. By increasing animals’ varieties.
C. By promoting animals’ breeding.
D. By changing animals’ living environme nt.
29. What is the example of bats for in paragraph 3?
A. Explaining the influence of Nipah virus.
B. Proving the harm of bats to human beings.
C. Showing the effects of climate change on disease.
D. Presenting scientists’ early study about the ca use of disease.
30. What can we infer from Fair’s words in paragraph 4?
A. Humans should give up studying animals.
B. Past data can solve the problems in the future.
C. Disease hot spots will disappear if animals die out.
D. Frequent contact with animals can cause disease outbreaks.
31. What could be the best title for the text?
A. Climate Change and Disease Spillover
B. Animals’ Interaction with Humans
D. Early Studies about Extreme Weather
C. Scientists’ Prediction for Disease Outbreaks
D
New App Helps People Remember Faces
Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people’s names only adds to the stress. A
new facial-recognition app could come to the rescue, but privacy experts
recommend proceeding with caution.
The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting some body,” says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.
After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee’s face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users’ data after an event.
Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s c reators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another co ntext that might come back to bite you.”
The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone’s face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data ar e stored only on a user’s phone, according to the team behind the app.
32. SocialRecall is used to ________.
A. take photos
B. identify people
C. organize events
D. make friends
33. Paragraph 3 is mainly about ________.
A. how the app works
B. how the app was created
C. what makes the app popular
D. what people can do with the app
34. SocialRecall helps people with prosopagnosia by ________.
A. giving names to the photos kept in their smartphones
B. collecting information previously entered in the phone
C. providing the information of a person when they first meet
D. showing the person’s information when it spots a stored face
35. What can we learn about SocialRecall from the passage?
A. It may put people’s privacy at r isk.
B. It has caused unintended consequences.
C. It can prevent some communication disorders.
D. It is praised by users for its protective measures.
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。选项中有两项为多余选项。
Studies show that people who are happy—truly happy—have deep connections with those around them. 36. They actively try hard to improve these relationships and build quality relationships with others.
Those connections and relationships that we build and that we attempt to develop,
create experiences in our lives. Some experiences will be poor, but it is possible for us to create meaningful experiences—experiences that allow us to just be. Studies show that when we create meaningful experiences, we allow ourselves time to relax, to build connections, and to become our best selves. 37.
If we want to create meaningful experiences, we need to learn how to create these moments in our lives. Instead of taking many classes and workshops to teach us how to build connections with others, we should experience be SHOPs, which means we learn by being, by observing, and by becoming.
38. It helps define us and motivates us to do good, to step outside of our comfort zone, and to be better. A few of these values that we need to create meaningful experiences include:
● Compassion(同情): Compassion has been thoroughly studied and proven to be a natural human response. 39. When you are compassionate, you don’t have to think twice about helping others.
● Gratitude: Showing sincere appreciation to other s helps establish strong feelings of gratitude, and build strong connections. You should express appreciation for all the things in your life and make gratefulness just a part of who you are.
● Willingness to learn: 40. Many individuals will find themselves stuck in their own world and never take a step outside of their comfort zones. When we have that desire to learn, to explore, and our curiosity is continually peaked, then we are more likely to have these meaningful experiences.
Remember, true happiness, and meaningful experiences are not things you can learn from a series of worksheets and lectures. It is about being.
A. There is so much in the world around us.
B. “To be” requires key values that shape us.
C. It means service, kindness and love for others.
D. Within the communities, you can work on developing these values.
E. Working with others will help you experience many aspects of life.
F. Creating these experiences is a vital step in the process to achieve full happiness.
G. They lay stress on the relationships with their family, friends ,colleagues and even
strangers.

宁夏银川一中2020 届高三第五次月考理科综合能力测试 化学试题 1.废电池投入的垃圾桶上应贴有的垃圾分类标志是 A B C D A. A B. B C. C D. D 【答案】A 【解析】 【分析】 废旧电池能严重污染水体和土壤，所以废干电池实施集中处理，以防止对水源和土壤的污染，它不属于金属，不能够燃烧，不属于玻璃材料，所以属于有害垃圾。 【详解】A．图示标志为有害垃圾，故A正确； B．图示标志为可回收垃圾，故B错误； C．图示标志为餐厨垃圾，故C错误； D．图示标志为其它垃圾，故D错误； 故选：A。 2.用N A代表阿伏加德罗常数的数值。下列说法正确的是 A. 3.6 g CaO2晶体中阴离子的数目为0.1N A B. 将7.1 g Cl2通入水中，转移电子数为0.1N A C. 标准状况下，11.2 L O2和CO2混合气体含有的氧原子数为N A D. 室温下，1L pH＝13的NaOH溶液中，由水电离出的OH－的数目为0.1N A 【答案】C 【解析】
【详解】A.3.6g过氧化钙的物质的量为0.05mol，而1mol过氧化钙中含1mol阴离子，故0.05mol 过氧化钙中含0.05N A个阴离子，故A错误。 B．氯气与水反应为可逆反应，不能进行到底，所以将7.1 g Cl2通入水中，转移电子数小于0.1N A，故B错误； C．O2和CO2均含两个氧原子，标准状况下，11.2 L O2、CO2混合气体物质的量为0.5mol，含有的氧原子数为N A，故C正确； D．在氢氧化钠溶液中，氢原子的物质的量浓度为10-13mol/L，全部来自于水的电离，而水电离出的氢氧根的浓度等于水电离出的氢离子的浓度，故pH=13的氢氧化钠中，水电离出的氢氧根的个数为10-13N A ，故D错误； 故答案为C。 3.下列反应 的离子方程式正确的是A. 碳酸钠的水溶液呈碱性：CO32-＋2H2O H2CO3＋2OH－B. 用CH3COOH溶解CaCO3：CO32-+CH3COOH=CH3COO-+H2O+CO2↑ C. 向Fe (OH)3胶体中加入氢碘酸溶液：Fe(OH)3+3H+=Fe3++3H2O D. 氯化亚铁溶液中通入氯气：2Fe2++Cl2=2Fe3++2Cl- 【答案】D 【解析】 【详解】A、碳酸钠水溶液呈碱性的原因是因为碳酸根离子水解：CO32-+H2O HCO3-+OH-；故A错误； B、醋酸是弱电解质，写化学式，离子方程式为 CaCO3+2CH3COOH═Ca2++H2O+CO2↑+2CH3COO-，故B错误； C、向Fe（OH）3胶体中加入氢碘酸溶液，二者发生氧化还原反应，正确的离子方程式为：2Fe （OH）3+6H++2I-=2Fe2++I2+6H2O，故C错误； D. 氯化亚铁溶液中通入氯气，氯气氧化亚铁离子，离子方程式为：2Fe2++Cl2=2Fe3++2Cl-，故D正确； 故答案为D。 【点睛】注意明确离子方程式正误判断常用方法：检查反应物、生成物是否正确，检查各物质拆分是否正确，如难溶物、弱电解质等需要保留化学式，检查是否符合原化学方程式等。 4.某铁的氧化物（Fe x O）1.52g溶于足量盐酸中，向所得溶液中通入标准状况下112mlCl2，恰好将Fe2+完全氧化。x值为（）
