问题     The idea of robots controlled by the human brain has long been a staple of science fiction, but efforts to create human-robot symbiosis (共生，合作) in the real world have mostly been limited to prosthetics (修复学，弥补术). Researchers are now【C1】________ to change that, with a system that lets people control a humanoid robot just by thinking about it.
    A team from MIT and Boston University have created a【C2】________ system that works using an electroencephalography (EEG) cap that records brain activity and relays it to a robot in real time, 【C3】________ the robot to move to correct its mistakes.
    The study made use of a humanoid robot, requiring it to sort paint cans from spools of wire. The system developed is able to【C4】________ if a person notices the robot make an error, and the signal relayed causes the robot to correct its mistake.
    The biggest【C5】________ is the way in which the robot is able to understand what the human controller is thinking without the person having to change their【C6】________  thought patterns. Past work in EEG-controlled robotics has required training humans to think in a【C7】________ way that computers can recognize.
    To make the experience more natural, the researchers focused on brain signals called error-related【C8】________ which generate naturally in the brain whenever we notice a mistake.
    While the system only【C9】________ handles binary-choice (二元的) activities like object sorting, the researchers believe the study paves the way for robots becoming a more natural extension of humans. The ability to control machines more【C10】________ could eventually improve our abilities to supervise factory robots, and control prosthetics or even self-driving cars.
    A) aiming          F) detect        K) patterns
    B) breakthrough    G) evaluate      L) potentials
    C) causing         H) feedback      M) predicted

【C1】
选项
答案A
解析 动词辨析题。空格位于系动词are和副词now之后，据此推断应填入动词的现在分词形式，与系动词are构成现在进行时。根据上文可知，长期以来人脑直接控制机器人的想法还只是存在于科幻小说中，在现实中的应用还十分局限。由此可推测此处是说研究人员想要改变这种状况，故答案为A)aiming“目的在于……”。
