问题     Not long ago, the only time you’d see a robot is 【S1】______ you were reading a novel or watching a movie such as Star Wars. Today, however, science stories are fast becoming science facts. Robots are starting to make their 【S2】______ felt in our everyday lives.
    These robots come in all sizes, shapes, and colors. They all have the same type of man-made "brain". Leading the robot revolution are 【S3】______ robots—robots that work in factories. Industrial robots 【S4】______ different kinds of jobs that are often 【S5】______ and sometimes dangerous. Robots are also coming to American 【S6】______, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you see in Star Wars. But, their makers say today’s home robots can walk, sense objects in their own way(and sometimes knock into them), and even carry objects(which they sometimes drop). Well, nobody’s perfect.
    We may laugh at home robots today, 【S7】______ some day they may see and hear better than humans do. We humans can only see certain wavelengths of light, and hear certain sounds. That’s because the abilities of our eyes and ears are 【S8】______. Robots, however, need not have the same limits as we have. Robots may also be 【S9】______ with devices that pick up information humans can’t.
    To understand how their sensing devices pick up their orders is a hard job. Remember, man-made brains handle information, including all kinds of data, as zeroes and ones. Imagine the difficulty 【S10】______ trying to explain to a robot what a football looks like using only zeroes and ones.
