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 (二元选择) 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

【C9】
选项
答案D
解析 副词辨析题。空格位于副词only之后、谓语动词handles之前，且从句基本结构完整，可判断此处应填入副词。空格所在从句之后是研究人员对此项研究发展趋势的展望，而空格所在从句则是总结上文提到过的研究项目，可知作者在此对比现在与将来的情况，故答案为D项currently “目前，现在”。
