Ⅰ.阅读理解
A
(2019·全国卷Ⅱ)
“You can use me as a last resort (选择), and if nobody else volunteers, then I will do it.”This was an actual reply from a parent after I put out a request for volunteers for my kids' lacrosse (长曲棍球) club.
I guess that there's probably some demanding work schedule, or social anxiety around stepping up to help for an unknown sport.She may just need a little persuading.So I try again and tug at the heartstrings．I mention the single parent with four kids running the show and I talk about the dad coaching a team that his kids aren't even on...At this point the unwilling parent speaks up，“Alright.Yes，I'll do it.”
I'm secretly relieved because I know there's real power in sharing volunteer responsibilities among many.The unwilling parent organizes the meal schedule, sends out emails, and collects money for end-of-season gifts.Somewhere along the way, the same parent ends up becoming an invaluable member of the team.The coach is able to focus on the kids while the other parents are relieved to be off the hook for another season. Handing out sliced oranges to bloodthirsty kids can be as exciting as watching your own kid score a goal.
Still, most of us volunteers breathe a sigh of relief when the season comes to a close.That relief is coupled with a deep understanding of why the same people keep coming back for more：Connecting to the community (社区) as you freely give your time, money, skills, or services provides a real joy.Volunteering just feels so good.
In that sense, I'm pretty sure volunteering is more of a selfish act than I'd freely like to admit.However, if others benefit in the process, and I get some reward too, does it really matter where my motivation lies?
【语篇解读】 本文介绍作者自己参与并鼓励他人参与志愿者工作的经历，论述了志愿者工作的独特意义。
1．What can we infer about the parent from her reply in Paragraph 1?
A．She knows little about the club.
B．She isn't good at sports.
C．She just doesn't want to volunteer.
D．She's unable to meet her schedule.
解析：选C 推理判断题。根据第一段第一句“You can use me as a last resort (选择)，and if nobody else volunteers, then I will do it.”和第二段中的“the unwilling parent”可推断，这位家长不想做志愿者工作。故选C。
2．What does the underlined phrase “tug at the heartstrings” in Paragraph 2 mean?
A．Encourage teamwork.
B．Appeal to feelings.
C．Promote good deeds.
D．Provide advice.
解析：选B 词义猜测题。根据前一句“She may just need a little persuading.”以及后面的“the unwilling parent speaks up，‘Alright.Yes, I'll do it.'”可知，tug at the heartstrings的意思是“打动(她)”。
3．What can we learn about the parent from Paragraph 3 ?
A．She gets interested in lacrosse.
B．She is proud of her kids.
C．She'll work for another season.
D．She becomes a good helper.
解析：选D 细节理解题。根据第三段第三句中的“the same parent ends up becoming an invaluable member of the team”可知，这位家长最后成了一个好帮手。
4．Why does the author like doing volunteer work?
A．It gives her a sense of duty.
B．It makes her very happy.
C．It enables her to work hard.
D．It brings her material rewards.
解析：选B 细节理解题。根据第四段中的“Connecting to the community (社区) as you freely give your time, money, skills, or services provides a real joy.Volunteering just feels so good.”很容易看出来，作者觉得做志愿者工作很快乐。所以选B。
B
Has it come to this？Robots standing in for doctors at the hospital patients' bedside?
Not exactly，but some doctors have found a way to use a robot to check on patients while they're miles away from the hospital.
One is at Baltimore's Sinai Hospital.Equipped with cameras，a screen and microphone，the robot is guided into the rooms of Dr. Alex Gandsas' patients where he speaks to them as if he was right there.
“The system allows you to be anywhere in the hospital from anywhere in the world，” said the surgeon，who specializes in weight-loss operation.
Besides his normal morning and afternoon personal visits，Gandsas uses the $150，000 robot to visit patients at night or when problems arise.The robot can circle the bed and adjust the position of its two cameras，giving the perception from the patient's standpoint that the doctor is there.“They love it.They'd rather see me through the robot，” he said of his patients' reaction to the machine.Nurse Florence Ford，who has worked with the robot since it was introduced about 18 months ago，said patients have reacted well，particularly because “Seeing the doctor's face gives them confidence”．
Gandsas presented the idea to hospital leaders as a method to more closely observe patients following weight-loss operation.Since its introduction，Dr. Alex found that nearly one third of his 376 patients went out of hospital earlier than first expected.
Michael Chan，president of InTouch Technologies，said his company's device allows doctors to “be in more than one place at the same time”．
Speaking with Gandsas through one of the robots at company headquarters，Chan said the company designs applications for the devices in remote areas and for dealing with shortages of health care workers.“They will soon be big，”said Chan when asked about their future.
【语篇解读】 文章主要介绍了一种帮助医生检查病人的机器人。
5．According to Dr. Alex，the purpose of using robots in the hospital is that ．
A．robots can provide patients more fun than doctors
B．patients will be closely watched after being operated on
C．robots can free doctors from their great work pressure
D．hospitals can solve the problem of lacking medical workers
解析：选B 推理判断题。根据第六段第一句话可知，甘瑟斯医生向医院领导提出此主意是想在病人做过手术后能对他们进行更密切地观察。
6．By using robots，Dr. Alex finds that ．
A．patients visited by robots may recover completely sooner
B．the number of patients in his hospital is reducing a lot
C．he can operate on different patients at the same time
D．their hospital doesn't need as many medical workers as before
解析：选A 细节理解题。根据第六段第二句话可知，因为使用了机器人，近三分之一的病人比预料的要早出院，这说明病人恢复得更快一些。
7．From the last sentence，we can learn that Michael Chan thinks that ．
A．people won't believe robots will do well in the future
B．in the future bigger robots will be made to satisfy the needs
C．more robots of this kind will be used in hospitals in the future
D．the prices of the robots will be greatly reduced in the future
解析：选C 推理判断题。根据最后一段第一句话可知，Michael Chan认为机器人可以解决医护人员短缺的问题，由此判断在未来更多的医院会使用这种机器人。
8．What would be the best title for the passage?
A．Robots Replace Doctors to Treat Patients
B．Robots Visit Patients When Doctors Can't
C．High-tech Makes Patients Better Communicate with Doctors
D．Robots Have Begun to Play a Great Part in Hospital Management
解析：选B 主旨大意题。纵观全文可知，文章讲的是机器人在医生不在的时候，它们根据指令去看望病人，帮助医生检查照顾病人，并不是取代医生或参与医院管理，故A、D两项错误；C项并未指出文章的重点，只有B项能够概括文章大意。

2．Be kind
3 . Life is full of conflicts and disagreements，and that's why you should find more conservative(保守的) ways of dealing with them.For example，kindness can lessen the conflict.
3． 4
Peacekeepers tend to cooperate with people without bad emotions which usually lead to arguments and even conflicts.“The greatest victory is the battle not fought.” This saying is the life motto of a natural-born peacekeeper.Don't worry if you are not a natural-born peacekeeper.You can gain this skill during life.
4．Walk off
When the conflict is gathering pace and you can't manage to keep yourself，you should choose to handle the situation in another way.By all means，try to keep yourself away from stress. 5 . You should get away from the situation for a while.

Ⅰ.阅读理解
A
Whether in the home or the workplace，social robots are going to become a lot more common in the next few years.Social robots are about to bring technology to the everyday world in a more humanized way，said Cynthia Breazeal，chief scientist at the robot company Jibo.
While household robots today do the normal housework，social robots will be much more like companions than mere tools.For example，these robots will be able to distinguish when someone is happy or sad.This allows them to respond more appropriately to the user.
The Jibo robot，arranged to ship later this year，is designed to be a personalized assistant.You can talk to the robot，ask it questions，and make requests for it to perform different tasks.The robot doesn't just deliver general answers to questions；it responds based on what it learns about each individual in the household.It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home.They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market.The company's “Oshbot” robot is built to assist customers in a store，which can help the customers find items and help guide them to the product's location in the store.It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans，the more it learns.But Oshbot，like other social robots，is not intended to replace workers，but to work alongside other employees.“We have technologies to train social robots to do things not for us，but with us，” said Breazeal.
【语篇解读】 本文是一篇说明文。文章主要介绍了社交机器人的一些情况，提到社交机器人在接下来的几年内将会越来越普遍，其与家用机器人的区别在于它们可以与人面对面交流，可以应用于教育、医疗保健等领域。
1．How are social robots different from household robots?
A．They can control their emotions.
B．They are more like humans.
C．They do the normal housework.
D．They respond to users more slowly.
解析：选B 推理判断题。根据第一段第二句可以得知，B项所述“它们看起来更像人类”符合题干要求。文中提到它们能识别人类的情绪，而没有提到“它们能够控制自己的情绪”，故A项所述错误；C项“它们能做常规的家务”是描述家用机器人的，不符合题干要求；文中第二段末句提到“...respond more appropriately to the user”，即这种机器人在回应使用者时会更贴切，而不是“更慢”，D项所述错误。
2．What can a Jibo robot do according to Paragraph 3?
A．Communicate with you and perform operations.
B．Answer your questions and make requests.
C．Take your family pictures and deliver milk.
D．Obey your orders and remind you to take pills.
解析：选D 细节理解题。根据第三段的第三句及末句可知，Jibo机器人在服从人们指令的同时也能提醒人们按时吃药，D项所述符合题干要求。A项中的“做手术”在文中未涉及；文中第三段第三句话提到机器人可以回答我们的问题，但没有提到它可以向我们提出请求，故B项所述错误；C项中的“送牛奶”在文中未涉及。
3．We can learn from the last paragraph that social robots will ．
A．train employees B．be our workmates
C．improve technologies D．take the place of workers
解析：选B 推理判断题。根据末段中的第二句话“...but to work alongside other employees.”可知，社交机器人将会成为我们的同事，B项所述正确。A项“培训员工”、C项“改进科技”与D项“取代工人”均不符合原文意思。
4．What does the passage mainly present?
A．A new design idea of household robots.
B．Marketing strategies for social robots.
C．Information on household robots.
D．An introduction to social robots.
解析：选D 主旨大意题。本文首段对社交机器人做了综述性介绍，然后分段开始举例说明社交机器人的用途及性能等情况，故本文主要是对社交机器人的介绍，D项所述符合本文主旨。A项“家用机器人的新设计思维”、B项“社交机器人的市场营销策略”与C项“家用机器人的信息”均为干扰项。
B
Hollywood's theory that machines with evil (邪恶的) minds will drive armies of killer robots is just silly.The real problem relates to the possibility that artificial intelligence (AI) may become extremely good at achieving something other than what we really want.In 1960 a well-known mathematician Norbert Winner，who founded the field of cybernetics (控制论)，put it this way，“If we use，to achieve our purposes，a mechanical agency with whose operation we cannot effectively interfere (干预)，we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”
A machine with a specific purpose has another quality，one that we usually associate with living things：a wish to preserve its own existence.For the machine，this quality is not in-born，nor is it something introduced by humans；it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead.So if we send out a robot with the single instruction of fetching coffee，it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task.If we are not careful，then，we could face a kind of global chess match against very determined，super intelligent machines whose objectives conflict with our own，with the real world as the chessboard.
The possibility of entering into and losing such a match should concentrate the minds of computer scientists.Some researchers argue that we can seal the machines inside a kind of firewall，using them to answer difficult questions but never allowing them to affect the real world.Unfortunately，that plan seems unlikely to work：we have yet to invent a firewall that is secure against ordinary humans，let alone super intelligent machines.
Solving the safety problem well enough to move forward in AI seems to be possible but not easy.There are probably decades in which to plan for the arrival of super intelligent machines.But the problem should not be dismissed out of hand，as it has been by some AI researchers.Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans.Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility.Still others think that super intelligent AI will never happen.On September 11，1933，famous physicist Ernest Rutherford stated，with confidence，“Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However，on September 12，1933，physicist Leo Szilard invented the neutron-induced (中子诱导) nuclear chain reaction.
【语篇解读】 本文是一篇议论文。文章讨论了人工智能随着科技的发展可能超出人类的控制以及人类应该如何应对此类安全问题。
5．Paragraph 1 mainly tells us that artificial intelligence may ．
A．run out of human control
B．satisfy human's real desires
C．command armies of killer robots
D．work faster than a mathematician
解析：选A 细节理解题。由第一段中的“artificial intelligence(AI)may become extremely good at achieving something other than what we really want”“人工智能可能会变得极度善于达成某事而不是我们真正想要的那样”可知，人工智能可能会超出人类控制，故选A项。而B项“满足人类的真正渴望”，C项“指挥杀手机器人大军”，D项“比数学家工作更快”，均与第一段所提到的人工智能无关。
6．Machines with specific purposes are associated with living things partly because they might be able to ．
A．prevent themselves from being destroyed
B．achieve their original goals independently
C．do anything successfully with given orders
D．beat humans in international chess matches
解析：选A 细节理解题。由题干中的“Machines with specific purposes”可定位到第二段第一句“A machine with a specific purpose has another quality，one that we usually associate with living things：a wish to preserve its own existence.”，由此可知，机器人要保证自己的存在，即A项“避免它们自己被消灭掉”。而B项“独立达到它们的初始目标”，C项“按照既有指令成功地完成任何事”，D项“在国际象棋比赛中击败人类”，均答非所问。
7．According to some researchers，we can use firewalls to .
A．help super intelligent machines work better
B．be secure against evil human beings
C．keep machines from being harmed
D．avoid robots' affecting the world
解析：选D 细节理解题。由第三段中的“Some researchers argue that we can seal the machines inside a kind of firewall，using them to answer difficult questions but never allowing them to affect the real world.”可知，一些研究者认为，我们可以用防火墙让机器人回答难题，但从不允许它们影响真实世界，故选D项“避免机器人影响世界”。而A项“帮助超级智能机器更好地工作”，B项“反抗邪恶人类，保证安全”，C项“保护机器不受损害”，都不是防火墙的用途，均可排除。
8．What does the author think of the safety problem of super intelligent machines?
A．It will disappear with the development of AI.
B．It will get worse with human interference.
C．It will be solved but with difficulty.
D．It will stay for a decade.
解析：选C 推理判断题。由最后一段首句“Solving the safety problem well enough to move forward in AI seems to be possible but not easy.”可知，作者认为，解决超级智能机器的安全问题是可能的，但并非易事，故选C项。而A项“随着人工智能的发展，超级智能机器的安全问题会消失”；B项“随着人类干预，超级智能机器的安全问题会更严重”；D项“超级智能机器的安全问题会存在十年之久”，均在文中找不到依据。
