Belle, our tiny monkey, was seated in her special chair inside a chamber at our Duke University lab. Her right hand grasped a joystick (操纵杆) as she watched a horizontal series of lights on a display panel. She knew that if a light suddenly shone and she moved the joystick left or right to correspond to its position, she would be sent a drop of fruit juice into her mouth.
Belle wore a cap glued to her head. Under it were four plastic connectors, which fed arrays of microwires—each wire finer than the finest sewing thread—into different regions of Belle’s motor cortex (脑皮层), the brain tissue that plans movements and sends instructions. Each of the 100 microwires lay beside a single motor neuron (神经元). When a neuron produced an electrical discharge, the adjacent microwire would capture the current and send it up through a small wiring bundle that ran f
A. a plastic box next door
B. a computer at Cambridge University
C. a box of electronics in the booth
D. a box which, in turn, was linked to two computers

A.On a recent morning Natanel Dukan walked into the Paris offices of the French robot maker Aldebaran and noticed one of the company’s humanoid (类人的) NAO robots sitting on a chair. Mr. Dukan, an electrical engineer, could not resist. Bending over, he kissed the robot on the cheek. In response the NAO tilted its head and touched his cheek. It is certainly a very French application for a robot, but the intimate gesture by the $16,000, two-foot robot, now being used in academic research labs and robotic soccer leagues, also reflects a significant shift.
B.Until recently, most robots were carefully separated from humans. They have largely been used in factories to perform repetitive tasks that required speed, precision and force. That generation of robots is dangerous, and they have been caged and fenced for the protection of workers.
C.But the industria
