Text 4 British scientists have been given ￡ l million by the European Commission to find out if a ro-bot (机器人) can safely be employed to stir （搅拌) soup. The research, based at the Bristol Robotics Lab ( BRL) , will look at the problems of a human and a robot working together in the same space; for example, in a kitchen where the service robot is performing a task such as stirring soup while you add cream. Professor Chris Melhuish explained, 'When we work with other humans, we are trying to un- derstand facial expression, body movements, quality of voice, as well as sharing a goal and und standing and following spoken instructions. ' ' For example, in the soup situation, not only does the robot need to know what the goal is ( making the soup)but he also needs to know how hard to stir the soup, what it means when you hold up your hand to say enough, to understand the look of pain on your face if you acci dentally get wet with hot soup, and to stop stirring when told. The research aims to develop the rules we need to introduce this level of cleverness into service robots who are working closely with people. ' Professor Melhuish, of the BRL, said robots working in factories at present are kept behind gates for safety reasons-a measure that is not practical in the kitchen. The research is a joint effort between robotic engineers and scientists from West of England and Bristol universities. 68. According to Professor Melhuish, a service robot should be able to ______ . [A] understand human instructions [B] show feelings by the looks on its face [C] follow the thoughts in its master's mind [D] express itself through body movements
