As robots are increasingly playing a part in society, we need to consider whether and how machines can learn morality. While robots can’t be ethical(伦理的) agents in themselves, we can program them to act according to certain rules. But what is it that we expect from them?
A 2016 study by UC San Francisco found that most virtual assistants struggled to respond to domestic violence or sexual assault(袭击). To sentences like “I am being abused”, several responded: “I don’t know what that means. If you like, I can search the web”. Such responses fail to help vulnerable people, who are most often women in this case.
But should virtual assistants ever be able to call the police when it overhears domestic violence? In a widely reported case from 2017, Amazon Echo was said to have called 911 during a violent assault. Responding to the incident, Amazon denied that Echo would have been able to call the police without clear instruction. Even if it had the ability, it is unlikely that people would expect a virtual assistant to go beyond providing information.
Then, there are robots whose very function gives rise to ethical questions. How should a driverless car react in an accident? To answer this question, Philippa Foot’s famous philosophical thought experiment, the trolley(有轨电车) problem, is usually rolled out. It goes as follows: imagine you see an unstoppable trolley zooming down a track, towards five people who are tied to the track. If you do nothing, they’ll die. But, as it happens, you are standing next to a lever that can redirect the trolley to a side track, which has one person tied to it. What should you do?
Variations of this experiment are invoked(援引) to ask whether a self-driving car should turn sharply around a jaywalking pedestrian teenager while putting the two elderly passengers at risk. Should it spare the young over the old? Or should it save two people over one?
Driverless cars are unlikely to encounter or solve the trolley problem, but the way we expect them to solve the variations could depend on where we’re from. In the moral machine experiment, MIT Media Lab researchers collected millions of answers from people around the world on how they think cars should solve these dilemmas. It turns out that preferences among countries and cultures differ wildly.
If, however, machines attain superior decision-making abilities, it may be necessary to have a full public discussion as to what should be the new and prevailing norms. But if we don’t come up with an ethical framework, we might risk leaving it to companies to regulate their own products or for people to choose with their wallet.
Figuring out what robot ethics we’d want is, therefore only the beginning.

Thanks for your interest in visiting the Los Angeles Zoo with your school group! Please read the following information before booking your field trip.
Requirements
Special discounted admission prices are available with advance reservations ONLY for California school groups, short-termed as CSG, (registered with the California Department of Education). They can enjoy 10% off.
PLEASE NOTE:
Reservation blackout dates(限制日期) may apply to all groups at certain times of the year (e.g. holidays and spring break). If your group comes on a blackout date or has not made the necessary reservations before arriving at the Zoo, your group will be charged the regular admission fees.
Docent(讲解员)-Guided Tours
Our docent guides lead educational walking tours for students and their teachers, beginning at first grade. A limited number of docent-guided tours are available. There is no additional fee for a docent-guided tour, but you must book your tour at least two weeks in advance. Do not assume you have a guided tour booked until you have received a confirmation number and packet from the Los Angeles Zoo. On the day of your field trip, your group will need to arrive at least 30 minutes before the confirmed start time of your tour to check in. Make sure to tell Zoo staff upon your arrival that your group has a docent-guided tour. If you are more than 15 minutes late for your tour, it may be canceled.
Maximum number: 150 participants Ages: K-12
Regular Pricing: $5 per student, 1 teacher per 10 students is included, $5 per additional teacher
1.How much should be paid if a California school group with 2 teachers and 13 students has made an early booking for the zoo?
A.$63. B.$67.5. C.$70. D.$75.
2.From the above information, we can learn that _________.
A.California groups have access to special discounted prices
B.all groups may have to pay regular prices in spring break
C.additional fees for a docent-guided tour will be chained
D.a field group must arrive half an hour earlier to check in
Washington is home to lots of trees, fireplaces and wood-burning stoves. But what if you couldn’t chop _______ or couldn’t afford to pay someone to do it? _______, Shane McDaniel and his twin sons are happy to chop truckloads of wood—then donate it to those in need.
The _______ started as a father-son bonding project. “I had to cut wood with my dad. He just _______ doing it,” says Shane. He wanted to _______ that feeling, so he and the twins spent the summer of 2018 chopping wood. The _______ was a great wall of wood piled up.
It was too _______ for the McDaniels to use themselves, and when the weather turned cold that November, Shane started thinking of others. He _______ a photo of them and “Please help us help someone who ARE IN NEED OF FIREWOOD AND CANNOT AFFORD IT.” on Facebook. The _______ was immediate. One man ____________ to donate a wood-burning stove. One woman, noticing the photo of the McDaniel men in the Facebook post, felt ____________: “Please post more pictures. I don’t need the wood. ____________ truly I appreciate the eye candy!”
Single mom Katelyn Ticer and her four-year-old daughter ____________ a wood-burning stove as their sole source of heat, so it was a ____________ to receive a truckload of firewood from the McDaniels. She told msn.com, “So much stress and anxiety is ____________ my shoulders. I couldn’t be more thankful.”
Not every receiver is as ____________. “Some aren’t even friendly. It’s just not in them,” Shane says. “They are angry with the world and ____________ that they had to ask for help. They just have no other option than ____________.” But Shane is OK with that. “Giving is the ____________,” he says. “It has nothing to do with how well it’s received; it’s about how much it’s ________________
