A good command of English.Sharon Okpoe has lived her entire 17 years in Makoko, known as the world * s largest floating slum （贫民窟）” ,built on a lake in Lagos, Nigeria. Okpoe' s father is a fisherman, and her mother sells smoked fish.As many as two-thirds of the city * s 21 million residents live in slums. “ Most girls are trapped in a terrible cycle of poverty. Many of them are not thinking of education, a plan for the future," Abisoye Ajayi-Akinfolarin, a computer programmer in Lagos, recalls. But several times a week, girls like Okpoe get a glimpse of another world when they attend GirlsCoding, a free program run by the Pearls Africa Foundation that seeks to educate and excite girls about computer programming. Since 2012, the group has helped more than 400 disadvantaged girls gain the technical skills and confidence they need to transform their lives.It , s the vision of Ajayi-Akinfolarin, who left a successful career to devote herself to this work. She*d noticed how few women worked in this growing field—a 2013 government survey found that less than 8% of Nigerian women were employed in technology jobs. She wanted to fix the gender gap. u Technology is a space that，s dominated by men. Why should we leave that to guys?" she said. "I believe girls need opportunities."Now, dozens of girls aged 10 to 17 get trained in computer programming technology. “I believe you can still find diamonds in these places,” Ajayi-Akinfolarin said. They need to be shown another life. n One way her program does diis is by taking the students to visit tech companies—not only showing them what technology can do, but also helping them visualize themselves joining the industry.Okpoe, for one, has taken this to heart. She helped create an app called Makoko Fresh that went live this summer, enabling fishermen like her father to sell seafood directly to customers. She even wants to become a software engineer and hopes to study computer science at Harvard. “ One thing I want my girls to hold onto is, regardless of where they are coming from, that they can make it," Ajayi said. u They are coders. They are thinkers. Their future is bright."4.What can we learn about GirlsCoding?A.It encourages girls to land a job in education.B.It offers Nigerian girls in need part-time jobs.C.It helps girls working in Lagos to fight poverty.D.It teaches girls in Makoko computer programming.5.What did Ajayi-Akinfolarin say about the growing field in Paragraph 3?A.Men could do far better in technology jobs.B.Girls should get equal work opportunities.C.Men normally got paid more than women.D.Girls tended to devote themselves to work.6.What does the underlined word "this" in Paragraph 4 refer to?A.Rebuilding the girls * confidence.B.Training the girls to find diamonds.C.Presenting a different life to the girls.D.Taking the girls to technology companies.7.What can we infer about Okpoe from the last paragraph?A.She got fishermen to benefit from her app.B.She was admitted to Harvard University.C.She took her father' s suggestion to heart.D.She made some changes to computer science.CTired of standing in line? Wait a bit longer, and you may never have to again. Everyone from Amazon to Silicon Valley startups is trying to eliminate lines in retail （零售）stores.Amazon has opened 24 of its Amazon Go stores, which use cameras and artificial intelligence to see what you5 ve taken off shelves and charge you as you walk out. Some startups are closely copying Amazon* s approach to using Al-powered cameras fixed in ceilings. But others are trying an entirely different way to skip the checkout： smart shopping carts. These companies have added cameras and sensors（传感器）to the carts, and are using Al to tell what you've placed in them. A built-in scale weighs items, in case you have to pay by the pound for an item. Customers pay by entering a credit card, or through an online payment system. When a customer exits the store, a green light on the shopping cart indicates that their order is complete, and they * re charged.The startups behind the smart carts, including Caper and Veeve, say it* s much easier to add technology to the shopping cart than to an entire store. Amazom, s Go stores rely on hundreds of cameras in the ceiling. The shelves also include sensors to tell when an item is removed. Ahmed Beshry, co-founder of Caper, believes the technology to run Go is too expensive to use in a large- fbrmat grocery store. Neither Caper nor Veeve have said how much their smart shopping carts will cost, making it difficult to compare the different formats. Shariq Siddiqui, CEO of Veeve, said he' s finding increased interest from retailers given Amazon' s steady expansion of Go since opening the first store in Seattle in 2018. “We' re always happy when Amazon is doing something,** Siddiqui said. "They force retailers to get out of their old school thinking."Each time a business uses artificial intelligence and cameras, it raises questions about customer privacy and the impact on jobs. Beshry notes that the cameras in his shopping cart point down into the cart,so only a customer * s hand and part of their arm will be captured （拍摄）on camera.8.Which of the following best explains “eliminate" underlined in Paragraph 1?A.Cross.B. Remove.C. Extend.D. Break.9.What do we know about the smart shopping carts?A.They are linked to the cameras fixed in the ceilings.B.They can tell customers where to find what they want.C.They flash the green light when the order is cancelled.D.They are able to recognize purchases placed in them.10.What does Beshry think of the technology applied in Amazon * s Go stores?A.It is far more expensive than their shopping carts.B.It may increase the cost of running a store greatly.C.It has attracted many more retailers than before.D.It is likely to help retailers to think differently.11.What is the best title for the text?A.The New Technology Promotes Retail SalesB.Al-powered Cameras Are Used in Retail StoresC.Smart Shopping Carts Will Let You Skip the LineD.Artificial Intelligence Affects the Future Job MarketDWalls blanketed in moss （苔蘇）are popping up in major cities, along with promises that they can reduce air pollution—but can a few square metres of plant matter really deal with the smog?A Berlin-based firm,Green City Solutions,believes so. Its moss walls, called the CityTree, are roughly4 square metres in size. Armed with Wi-Fi sensors to monitor the health of moss, a CityTree functions autonomously and requires very little maintenance （维护）.The wall collects rainwater, which is pumped through a built-in irrigation system to the plants, powered by solar energy. As a result, the firm says each CityTree is able to u eat n around 250 grams of particulate （颗粒）matter a day （nearly 90 kgs a year）and removes about 240 metric tons of CO2 annually. It also cools the surrounding air.Aware that getting the surrounding air in contact with the moss wall is crucial for the CityTree to be effective, the inventors ensure that the location of each installation （安装）is chosen carefully—spots where pollution is heavy due to traffic and where air flow is limited are picked. The importance of this step is explained by the fact that the waste gas from a car generally goes vertically a few kilometres into the air.But this doesn，t mean moss walls will necessarily protect people from pollution. In the Netherlands, researchers found that eight walls installed in Amsterdam failed to reduce the concentration of particulate matter （ PM） and nitrogen dioxide （ NO2）. Their report concluded that even doubling the number of moss walls would do little to improve their effectiveness.The CityTree is not meant for parks or to substitute for street trees, but to add greenery to concrete-heavy spaces where planting is not an option. It's important to remember that street trees provide a whole host of other benefits, including shelter and habitat for urban wildlife, shade and cooling for people on the street, and reduction of urban heat islands.12.What do we know about the CityTree?A.It can absorb some air pollutants.B. It can irrigate other street plants.C. It produces electricity to cool water.D.

A good command of English.BSharon Okpoe has lived her entire 17 years in Makoko, known as the world's largest "floating sl um（贫民窟）”，b u ilt on a lake in Lagos, Nigeria.Okpoe's father is a fisherman, and her mother sells smoked fish.As many as two-thirds of the city's 21 million residents live in slums. "Most girls are trapped in a terrible cycle of poverty. Many of them are not thinking of education, a plan for the future," Abisoye Ajayi-Akinfolarin, a computer programmer in Lagos, recalls. But several times a week, girls like Okpoe get a glimpse of another world when they attend GirlsCoding, a free program run by the Pearls Africa Foundation that seeks to educate and excite girls about computer programming. Since 2012, the group has helped more than 400 disadvantaged girls gain the technical skills and confidence they need to transform their lives.It's the vision of Ajayi-Akinfolarin, who left a successful career to devote herself to this work. She'd noticed how few women worked in this growing field-a 2013 government survey found that less than 8% of Nigerian women were employed in technology jobs. She wanted to fix the gender gap. "Technology is a space that's dominated by men. Why should we leave that to guys?" she said. "I believe girls need opportunities."Now, dozens of girls aged 10 to 17 get trained in computer programming technology. " I believe you can still find diamonds in these places," Ajayi-Akinfolarin said. "They need to be shown another life. " One way her program does 世 is by taking the students to visit tech companies 一 not only showing them what technology can do, but also helping them visualize themselves joining the industry.Okpoe, for one, has taken this to heart. She helped create an app called Makoko Fresh that went live this summer, enabling fishermen like her father to sell seafood directly to customers. She even wants to become a software engineer and hopes to study computer science at Harvard. "One thing I wantmy girls to hold onto is, regardless of where they are coming from, that they can make it, " Ajayi said. "They are coders. They are thinkers. Their future is bright. "4.What can we learn about GirlsCoding?A.It encourages girls to land a job in education.B.It offers Nigerian girls in need part-time jobs.C.It helps girls working in Lagos to fight poverty.D.It teaches girls in Makoko computer programming.5.What did Ajayi-Akinfolarin say about the growing field in Paragraph 3?A.Men could do far better in technology jobs.B.Girls should get equal work opportunities.C.Men normally got paid more than women.D.Girls tended to devote themselves to work.6.What does the underlined word " this" in Paragraph 4 refer to?A.Rebuilding the girls’ confidence.B.Training the girls to find diamonds.C.Presenting a different life to the girls.D.Taking the girls to technology companies.7.What can we infer about Okpoe from the last paragraph?A.She got fishermen to benefit from her app.B.She was admitted to Harvard University.C.She took her father's suggestion to heart.D.She made some changes to computer science.CTired of standing in line? Wait a bit longer, and you may never have to again. Everyone from Amazon to Silicon Valley startups is trying to lines in retail（零售）s tores.Amazon has opened 24 of its Amazon Go stores, which use cameras and artificial intelligenceto see what you've taken off shelves and charge you as you walk out. Some startups are closely copying Amazon's approach to using AI-powered cameras fixed in ceilings. But others are trying an entirely different way to skip the checkout: smart shopping carts. These companies have added cameras and sensor（s传感器）to the carts,and are using AI to tell what you’ve placed in them. A built-in scale weighs items, in case you have to pay by the pound for an item. Customers pay by entering a credit card, or through an online payment system. When a customer exits the store, a green light on the shopping cart indicates that their order is complete, and they're charged.The startups behind the smart carts, including Caper and Veeve, say it's much easier to add technology to the shopping cart than to an entire store. Amazom's Go stores rely on hundreds of cameras in the ceiling. The shelves also include sensors to tell when an item is removed. Ahmed Beshry, co-founder of Caper, believes the technology to run Go is too expensive to use in a large- format grocerystore. Neither Caper nor Veeve have said how much their smart shopping carts will cost, making it difficult to compare the different formats. Shariq Siddiqui, CEO of Veeve, said he's finding increased interest from retailers given Amazon's steady expansion of Go since opening the first store in Seattle in 2018. "We're always happy when Amazon is doing something," Siddiqui said. "They force retailers to get out of their old school thinking. "Each time a business uses artificial intelligence and cameras, it raises questions about customer privacy and the impact on jobs. Beshry notes that the cameras in his shopping cart point down into the cart, so only a customer's hand and part of their arm will be captured（拍摄）o n camera.8.Which of the following best explains " eliminate" underlined in Paragraph 1?A.Cross.B. Remove.C. Extend.D. Break.9.What do we know about the smart shopping carts?A.They are linked to the cameras fixed in the ceilings.B.They can tell customers where to find what they w a n t.C.They flash the green light when the order is cancelled.D.They are able to recognize purchases placed in them.10.What does Beshry think of the technology applied in Amazon's Go stores?A.It is far more expensive than their shopping carts.B.It may increase the cost of running a store greatly.C.It has attracted many more retailers than before.D.It is likely to help retailers to think differently.11.What is the best title for the text?A.The New Technology Promotes Retail SalesB.AI-powered Cameras Are Used in Retail StoresC.Smart Shopping Carts Will Let You Skip the LineD.Artificial Intelligence Affects the Future Job MarketDWalls blanketed in moss（苔鲜）are popping up in major cities, along with promises that they can reduce air pollution 一 but can a few square metres of plant matter really deal with the smog?A Berlin-based firm, Green City Solutions, believes so. Its moss walls, called the CityTree, are roughly 4 square metres in size. Armed with Wi-Fi sensors to monitor the health of moss, a City Tree functions autonomously and requires very little maintenance（维护）．The wall collects rainwater, which is pumped through a built-in irrigation system to the plants, powered by solar energy. As a result, the f i皿 says each CityTree is able to "eat" around 250 grams of particulate（颗粒）ma tter a day (nearly90kgs a year) and removes about 240 metric tons of CO2annually. It also cools the surrounding air.Aware that getting the surrounding air in contact with the moss wall is crucial for the CityTree to be effective, the inventors ensure that the location of each installation ( 安装） is chosen carefullys pots where pollution is heavy due to traffic and where air flow is limited are picked. The importance of this step is explained by the fact that the waste gas from a car generally goes vertically a few kilometres into the air.But this doesn't mean moss walls will necessarily protect people from pollution. In the Netherlands, researchers found that eight walls installed in Amsterdam failed to reduce the concentration of particulate matter (PM) and nitrogen dioxide (N02). Their report concluded that even doubling the number of moss walls would do little to improve their effectiveness.The CityTree is not meant for parks or to substitute for street trees, but to add greenery to concrete-heavy spaces where planting is not an option. It's important to remember that street trees provide a whole host of other benefits, including shelter and habitat for urban wildlife, shade and cooling for people on the street, and reduction of urban heat islands.12.What do we know about the CityTree?A.It can absorb some air pollutants.B. It can irrigate other street plants.C. It produces electricity to cool water.D.

费孝通早年在《乡土中国》一书中针对中国乡村结构提出了差序格局的概念，即每一家以自己的地位作为中心，在其周围划出一个圈子，这个圈子的大小要依着中心势力的厚薄而定。

差序格局具有大传统和小传统的双重属性：前者以克己主义为内核，表达儒家道德理想；后者以自我主义为内核，践行在绝大多数普通人的日常生活中。

克己主义的道德理想和自我主义的道德实践，构成了中国文化的大小传统。

费孝通提出差序格局的旨趣，与其说是刻画传统中国社会的基本特征，解释中国人的行动逻辑；毋宁在于以现代西方为他者，映照中国传统文化的特点，并呈现中国传统与西方现代性之间的深刻紧张。

费孝通理性意识到，西力东侵、西学东渐的世界大势决定了中国再也不可能独立于现代化洪流之外，然而中国的社会转型既不是西方社会制度的直接转渡，也不仅是传统的平衡受到了干扰而已。

文化的历史性和社会性，决定了社会变迁决非一个彻底告别传统、辞旧迎新的过程，而是一个建立在社会自身演化的内在逻辑之上的过程，一个传统与现代相互角力和冲突的过程。

中国文化的大传统与小传统在相容相克中蕴育出深刻的张力，这种张力决定了中国社会转型既不可能通过移植西方社会制度来完成，也不可能内生出独立的动力机制。
