问题    Neurotechnology has long been a favorite of science-fiction writers. In Neuromancer, a wildly inventive book by William Gibson written in 1984, people can use neural implants to jack into the sensory experiences of others. The idea of a neural lace, a mesh that grows into the brain, was conceived by Iain M. Banks in his "Culture" series of novels. The Terminal Man by Michael Crichton, published in 1972, imagines the effects of a brain implant on someone who is convinced that machines are taking over from humans. (Spoiler: not good.)
   Where the sci-fi genre led, philosophers are now starting to follow. In Howard Chizeck’s lab at the University of Washington, researchers are working on an implanted device to administer deep-brain stimulation (DBS) in order to treat a common movement disorder called essential tremor. Conventionally, DBS stimulation is always on, wasting energy and depriving the patient of a sense of control. The lab’s ethicist, Tim Brown, a doctoral student of philosophy, says that some DBS patients suffer a sense of alienation and complain of feeling like a robot.
   To change that, the team at the University of Washington is using neuronal activity associated with intentional movements as a trigger for turning the device on. But the researchers also want to enable patients to use a conscious thought process to override these settings. That is more useful than it might sound: stimulation currents for essential tremor can cause side-effects like distorted speech, so someone about to give a presentation, say, might wish to shake rather than slur his words.
   Giving humans more options of this sort will be essential if some of the bolder visions for brain-computer interfaces are to be realised. Hannah Maslen from the University of Oxford is another ethicist who works on a BCI project, in this case a neural speech prosthesis being developed by a consortium of European researchers. One of her jobs is to think through the distinctions between inner speech and public speech: people need a dependable mechanism for separating out what they want to say from what they think.
   That is only one of many ethical questions that the sci-fi versions of brain-computer interfaces bring up. What protection will BCIs offer against neural hacking? Who owns neural data, including information that is gathered for research purposes now but may be decipherable in detail at some point in the future? Where does accountability lie if a user does something wrong? And if brain implants are performed not for therapeutic purposes but to augment people’s abilities, will that make the world an even more unequal place?
   For some, these sorts of questions cannot be asked too early: more than any other new technology, BCIs may redefine what it means to be human. For others, they are premature. "The societal-justice problem of who gets access to enhanced memory or vision is a question for the next decades, not years, " says Thomas Cochrane, a neurologist and director of neuroethics at the Centre for Bioethics at Harvard Medical School.
   In truth, both arguments are right. It is hard to find anyone who argues that visions of whole-brain implants and AI-human symbiosis are impossible to realize; but harder still to find anyone who thinks something so revolutionary will happen in the near future. [br] What can we know from the description of Paragraph 2?
选项 A、Researchers are working on an implanted device to waste energy.
B、An implanted device can utilize deep-brain stimulation to treat movement disorder.
C、DBS patients enjoy a sense of alienation and a feeling like a robot.
D、An implanted device can treat a common language disorder.
答案 B
解析 根据题干定位至第2段。题目问从第2段的描述中，我们能了解到什么。研究人员研发植入式设备是为了治疗运动障碍，而非浪费能量，A项表述错误；C项“DBS患者很享受隔离与像机器人的感觉”，与原文内容相反；D项“植入式设备能治疗语言紊乱”，与原文不符。因此正确答案为B项“植入式设备利用深部脑刺激(DBS)来治疗被称为特发性震颤的一种常见的运动障碍”，其与原文一致。
