In Forsyth County，North Carolina，this concept is already being put into practice.The county has launched a pilot program where drones are sent to heart attack scenes.Pilots remotely operate the drones，enabling them to reach emergency scenes faster than ambulances，and reducing the time it takes to deliver essential aid. However，to ensure drones can maintain an effective operation in challenging situations，certain measures must be in place.For instance，drones need to be resistant to extreme weather conditions，which can significantly impact flight stability.Therefore，it’s also very necessary to equip drones with advanced weatherproofing materials and enhance stabilization systems to ensure they can function well in diverse conditions. There is also another issue to be addressed.As Jay Stanley，a senior policy analyst，points out，“The cameras on drones might record lots of other people’s information when the drones are performing a task，and if the government has no equal measures to deal with that，it is possible that many people on the ground would be potential victims.” Obviously，the application of drones in emergency response will progress through technological innovation.While traditional rescue methods remain the mainstream approach，working with drones will enhance rescuers’ capabilities，providing new ways to manage emergencies more effectively. 1.How do drones improve medical services in emergencies? A.By promoting the operation efficiency. B.By avoiding mistakes in medical treatment. C.By helping ease bad traffic on the ground. D.By making detailed assessments in advance. √ 细节理解题。根据第一段中“They can arrive at the scene faster than paramedics(护理人员) and reach areas that are difficult for ground vehicles to access...”可知，无人机可以快速到达救援现场，从而提升了急救效率。故选A。 解析 2.What is the author’s purpose of mentioning the example in paragraph 4? A.To stress drones’ adaptability to tough conditions. B.To call for technical advances in drone design. C.To point out the unpredictability of weather. D.To show the necessity of drone maintenance. √ 写作目的题。根据第四段中“However，to ensure drones can maintain an effective operation in challenging situations，certain measures must be in place.”可知，为了确保无人机在恶劣环境中保持有效操作，必须采取一些必要的措施。因此，作者举例——改善恶劣天气应对能力和系统稳定性，旨在呼吁对无人机的设计进行技术升级，以便更好地适应各种环境。故选B。 解析 3.What may concern Jay Stanley about the application of drones? A.Failing to win the government’s support. B.Interrupting people’s everyday life. C.Lacking experienced operators. D.Giving away personal privacy. √ 细节理解题。通读第五段可知，Jay Stanley 指出无人机在执行任务期间，摄像头可能会记录其他人的信息，政府若是没有相应的应对措施，有一些人可能会成为潜在的受害者。由此可知，Jay Stanley 担心人们的隐私会被泄露。故选D。 解析 4.How does the author find using drones for emergency services? A.Promising. B.Unnecessary. C.Problematical. D.Inexpensive. √ 观点态度题。根据最后一段可知，作者认为无人机在应急响应中的应用会通过技术创新而不断进步。虽然传统的救援方法仍然是主流方法，但与无人机合作将增强它们的能力，为更有效地管理紧急情况提供新的方法。由此可知，作者认为无人机在紧急服务中的应用是“很有前景的”。故选A。 解析 B To protect people living in areas that are likely to suffer flooding and rising sea levels，a group of architects has designed a floating home. 语篇解读　这是一篇说明文。建筑公司和制造商正在设计漂浮房屋来为容易遭受洪灾或被海水淹没的地区提供解决方案，文章介绍了这种房屋的特点和意义。 The project is a collaboration between British architect firm Grimshaw and Dutch manufacturer Concrete Valley.Currently at the design stage，the home will be constructed using a concrete and glass framework，which sits on a floating pontoon structure.In the event of a tidal surge or flooding，the pontoon rises with the water level to keep the home safe.Fitted with solar panels and heat exchangers，the floating home will be able to produce their own electricity during power cuts，in the event of a storm. Other firms are exploring floating homes，too.In the UK，Baca Architects has partnered with manufacturer Floating Homes.Their design was originally an entry to a competition to reduce London’s housing shortage，and has since been turned into a prototype.Baca Architects is exploring ways to provide practical，affordable，flood-resistant additional city housing，which could occupy unnecessary docks，canals and other waterways throughout London，director Richard Coutts told The Guardian. As the planet’s atmosphere warms，areas such as the Arctic are melting fast，contributing to rising sea levels and higher risk of flooding.The ocean is already reclaiming land in some parts of the world.With the global population set to reach 9.8 billion people by mid-century，extreme flooding could further add pressure to limited land，water，food and other resources.These challenges are at the heart of the Virtual Ocean Dialogues，an initiative by the World Economic Forum and Friends of Ocean Action.The online event provides a forum for more than 50 world leaders to address the most pressing challenges facing our oceans and develop ways to protect them. While floating homes may be a common feature in parts of Asia and other developing regions，they are emerging as a way to relieve overcrowding and protect people in busy cities and urban areas which are likely to suffer flooding. 5.What makes it possible to produce electricity in the floating home? A.The concrete and glass framework. B.The tidal power. C.Solar panels and heat exchangers. D.The floating pontoon structure. √ 细节理解题。根据第二段的“Fitted with solar panels and heat exchangers，the floating home will be able to produce their own electricity during power cuts，in the event of a storm.”可知，太阳能电池板和热交换器使得在漂浮的房子里发电成为可能。故选C。 解析 6.What can we learn from paragraph 3? A.Floating homes will be useful but costly. B.Floating homes have been put into use in London. C.Baca Architects’ design was to ease the housing burden at first. D.There is a competition among firms in the UK to explore floating homes. √ 细节理解题。根据第三段的“In the UK，Baca Architects...Their design was originally an entry to a competition to reduce London’s housing shortage...”可知，Baca建筑事务所的设计最初是为了减轻住房负担。故选C。 解析 7.What does the underlined word “reclaiming” in paragraph 4 probably mean? A.Restoring. B.Reoccupying. C.Redeveloping. D.Reshaping. √ 词义猜测题。根据画线词上文“As the planet’s atmosphere warms，areas such as the Arctic are melting fast，contributing to rising sea levels and higher risk of flooding.”可知，气候变暖导致海平面上升，海水淹没陆地的可能性变大，所以世界上的一些地方应是正在被海洋再次占领。故画线词意思是“再占领”。故选B。 解析 8.What can be a suitable title for the text? A.Melting Oceans Are Causing Rising Sea Levels B.A Forum Is Ongoing to Explore Floating Homes C.Many Firms Are Working Together to Reduce Housing Shortage D.Floating Homes Are Emerging to Protect People from Flooding √ 标题归纳题。根据第一段“To protect people living in areas that are likely to suffer flooding and rising sea levels，a group of architects has designed a floating home.”并结合下文对漂浮房屋的研发进程及其意义的介绍可知，D选项适合作为文章标题。故选D。 解析 It is believed that it’s dangerous to have plants in the bedroom.Plants take in carbon dioxide(CO2) and produce oxygen(氧气) in the day. 语篇解读　本文为一篇说明文，说明了和室内盆栽植物共用卧室是否会损害健康，并告诉我们室内盆栽植物对我们的重要性。 Ⅵ.七选五阅读 1 The build-up of CO2 is a real problem for indoor air quality，which has been shown to influence health，so it is easy to see where the concern comes from.But to consider whether sharing our bedroom with our plants can harm health，we should consider three things. A.This is hard to answer. B.So，they are quite necessary. C.The question has more than one answer. D.Besides，we often share a room with someone else. E.Indoor air is being exchanged through doors and windows. F.At night they compete with us for the air we breathe while asleep. G.Secondly，compare the influence of a plant with that of a person sharing a room. √ 根据前文“It is believed that it’s dangerous to have plants in the bedroom.Plants take in carbon dioxide (CO2) and produce oxygen(氧气) in the day.”及后文“The build-up of CO2 is a real problem for indoor air quality，which has been shown to influence health，so it is easy to see where the concern comes from.”可知，空处应描述人们认为卧室里有植物会有危险的原因，F选项“在晚上，它们与我们争夺我们睡觉时呼吸的空气”解释原因。故选F。 解析 Firstly，how much CO2 do plants produce at night compared with what they take in during the day？ 2 For the answer depends on everything from species to light levels and even room temperature.Thankfully，in 2015，researchers at Turkey’s Kastamonu University found that large houseplants take in between six and eight times as much CO2 in the day as they produce at night. A.This is hard to answer. B.So，they are quite necessary. C.The question has more than one answer. D.Besides，we often share a room with someone else. E.Indoor air is being exchanged through doors and windows. F.At night they compete with us for the air we breathe while asleep. G.Secondly，compare the influence of a plant with that of a person sharing a room. √ 空前“Firstly，how much CO2 do plants produce at night compared with what they take in during the day？”提出问题：“植物在夜间产生的二氧化碳与白天吸收的相比有多少？”；后文“For the answer depends on everything from species to light levels and even room temperature.”指出这个问题的答案取决于很多方面，即这个问题是难以回答的，A选项符合语境。故选A。 解析 3 A single human breath contains around 40,000 ppm of CO2，more than 10 times the effect a plant could have in 8 hours，so you might want to throw your partner out before your plants. A.This is hard to answer. B.So，they are quite necessary. C.The question has more than one answer. D.Besides，we often share a room with someone else. E.Indoor air is being exchanged through doors and windows. F.At night they compete with us for the air we breathe while asleep. G.Secondly，compare the influence of a plant with that of a person sharing a room. √ 根据上一段的Firstly，下一段的Finally及本段下文可知，该空应讲第二点，且把植物和人作比较，G选项符合语境，引起下文。故选G。 解析 Finally，we don’t live in the sealed(密封的) boxes in which these studies are carried out. 4 The air is even exchanged when we move around. A.This is hard to answer. B.So，they are quite necessary. C.The question has more than one answer. D.Besides，we often share a room with someone else. E.Indoor air is being exchanged through doors and windows. F.At night they compete with us for the air we breathe while asleep. G.Secondly，compare the influence of a plant with that of a person sharing a room. √ 前文“Finally，we don’t live in the sealed(密封的) boxes in which these studies are carried out.”及后文“The air is even exchanged when we move around.”可知，E选项“室内空气通过门窗进行交换”符合语境，表明人的生活空间与外界相连，没有处在研究实验条件下，空气是流通的，且与空后一句形成递进关系。故选E。 解析 According to one recent review，we need houseplants to keep indoor air fresh，and to fight some pollution. 5 A.This is hard to answer. B.So，they are quite necessary. C.The question has more than one answer. D.Besides，we often share a room with someone else. E.Indoor air is being exchanged through doors and windows. F.At night they compete with us for the air we breathe while asleep. G.Secondly，compare the influence of a plant with that of a person sharing a room. √ 根据前文“According to one recent review，we need houseplants to keep indoor air fresh，and to fight some pollution.”可知，室内盆栽植物对我们来说是重要的，B选项“所以，它们是非常必要的”符合语境，B项中they指代前文的houseplants。故选B。 解析 Let’s enjoy houseplants whenever we like，because if sleeping near plants were bad for our health，camping in a forest would be deadly. 本课结束 $
