问题     (1) Someday soon, you will ask a robot to fetch a slice of pizza from your refrigerator. On that day, you’ll trust that the robot won’t tear through your walls and rip the fridge door off its hinges to get at your leftovers.
    (2) Getting robots to do the things humans do in the ways that humans do them (or better) without human intervention is an immensely wicked problem of autonomy. With as many as half of American jobs at risk of automation according to one study, and with an expected 10 million self driving cars on the road by 2020, robots are going to be everywhere, forever, and they won’t go away.
    (3) The enormous scope and scale of how autonomous robots will begin changing our lives requires the public and technologists alike to consider the challenges of autonomy. Where will we allow robots to intervene into our lives? How do we make ethical judgments about the behavior of robots? What kind of partnerships will we develop with them? These are big questions. And one key challenge at the core of many of them is, in roboticist talk, what it means to establish "meaningful human control," or sufficient oversight over an autonomous agent. To get a grip on our autonomous future, we’ll need to figure out what constitutes "enough" oversight of a machine imbued with incredible intelligence.
    (4) Today, most robots are made to accomplish a very specific set of tasks within a very specific set of parameters, such as geographic or time limitations, that are tied to the circuits of the machine itself. "We’re not at the stage where robots can do everything that humans can do," says Dr. Spring Berman, assistant professor of mechanical and aerospace engineering at Arizona State University. "They could be multi-functional but they’re limited by their hardware."
    (5) Thus, they need a human hand to help direct them toward a specific goal, in a futuristic version of ancient dog and human partnerships, says Dr. Nancy Cooke, a professor of human systems engineering at ASU, who studies human-machine teaming. Before dogs can lead search and rescue teams to buried skiers or sniff out bombs, they require an immense amount of training and "on-leash" time, Cooke says, and the same level of training is necessary for robots, though that training is usually programmed and based on multiple tests as opposed to the robot actually "learning."
    (6) Even after rigorous "training" and vetting against a variety of distractions and difficulties, sometimes robots still do things they aren’t supposed to do because of quirks buried in their programming. In those cases, someone needs to be held accountable if the robot goes outside of its boundaries.
    (7) "It can’t be some patsy sitting in a cubicle somewhere pushing a button," says Dr. Heather Roff, a research scientist at ASU’s Global Security Initiative and senior research fellow at Oxford University. "That’s not meaningful." Based on her work with autonomous weapons systems, Dr. Roff says she is also wary of the sentiment that there will always be a human around. "A machine is not a morally responsible agent," she says, "a human has to have a pretty good idea of what he’s asking the system to do, and the human has to be accountable."
    (8) The allure of technology resolving problems difficult for humans, like identifying enemy combatants, is immense. Yet technological solutions require us to reflect deeply on the system being deployed：How is the combatant being identified? By skin tone, or gender or age or the presence or absence of certain clothing? What happens when a domestic police force deploys a robot equipped with this software? Ultimately, whose finger is on the trigger?
    (9) Many of the ethics questions in robotics boil down to how the technology could be used by someone else in the future, and how much decision-making power you give to a robot, says Berman. "I think it’s really important that a moral agent is the solely responsible person [for a robot]," says Roff. "Humans justify bad actions all the time even without robots. We can’t create a situation where someone can shirk their moral responsibilities." And we can’t allow robots to make decisions without asking why we want robots to make those decisions in the first place. Answering those questions allows us to understand and implement meaningful human control.
The scene in Para. 1 is described to ______.
选项 A、compare two generations of robots
B、show the development of autonomy
C、reveal the enormous power of robots
D、warn us against the potential threats
答案B
解析 原文第一段描绘了一个情景，一个机器人会从冰箱里拿出披萨，而且不会出现穿墙而过、误拆冰箱门等情况。而第二段第一句指出，让机器人以人类的方式，甚至优于人类的水平来完成以往人类所做的事情，而不需要人类干预，正是自动化遇到的问题，最后一句则提到，到2020年，机器人可能会遍布各处。由此可见，这一情景描写能够反映出机器人（自动化）的发展，故B项为答案。文章中没有明确提到有不同代的机器人，因此排除A项；从文章的后续论述可以看出，C项“显示机器人的巨大力量”和D项“警示我们潜在的威胁”与文章的主要论题不相关，因此均应排除。
