问题     Traditionally, robots have been hard, made of metal and other rigid materials. But a team of scientists at Harvard University in the US have managed to build an entirely soft robot—one that draws inspiration from an octopus (章鱼).
    Described in the science journal Nature, the " Octobot" could pave the way for more effective autonomous robots that could be used in searches, rescue and exploration. "The Octobot is the minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots," the study’s authors wrote.
    Robots built for precise, repetitive movements in a controlled environment don’t do so well on rough terrains(地形) or in unpredictable conditions. And they aren’t especially safe around humans, because they’ re made out of hard and heavy parts that could be potentially dangerous for their users.
    So researchers have been working on building soft robots for decades. They’ve taken inspiration from nature, looking at animals from jellyfish to cockroaches, which are often made up of more flexible matter.
    But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it’s still a grand challenge to construct flexible versions of essential parts, such as a source of power.
    "Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-and-rescue operations and exploration," Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology’s Center for Micro-Bio Robotics, wrote in a comment. "Soft robots might also open up new approaches to improving wellness and quality of life.
What can soft robots probably be used for?
选项 A、Medical research.
B、Life rescue.
C、Machine operation.
D、House cleaning.
答案B
解析 根据第二段第一句“…the " Octobot" could pave the way for more effective autonomous robots that could be used in searches, rescue and exploration. ”可知，“章鱼机器人”为更有效的自主机器人铺平了道路，这些机器人可以用于搜索、救援和勘探。由此可推知，像“章鱼机器人”一样的软体机器人可能被用来拯救生命(life rescue)。medical research：医学研究；machine operation：机器操作；house cleaning：打扫房屋。故选B。
