On an average of six times a day, a
doctor in Holland practices "active" euthanasia: intentionally administering a
lethal (致死的) drug to a terminally ill patient who has asked to be relieved of
suffering. Twenty times a day, life-prolonging treatment is withheld or
withdrawn when there is no hope that it can effect an ultimate cure. "Active"
euthanasia remains a crime on the Dutch statute books, punishable by 12 years in
prison. But a series of court cases over the past 15 years has made it clear
that a competent physician who carries it out will not be prosecuted. Euthanasia, often called "mercy killing", is a crime everywhere in Western Europe. But more and more doctors and nurses readily admit to practicing it, most often in the "passive" form of withholding or withdrawing treatment. The long simmering euthanasia issue has lately boiled ove A. Euthanasia is not regarded as a crime in France. B. More and more medical workers like to practice euthanasia, no matter what form it takes. C. The problem of euthanasia is now being debated heatedly and openly. D. There is not much difference between "active" and "passive" euthanasia. [单选题]各级党委安全生产工作职责:将安全生产工作纳入( )工作全局和经济社会发展规划纲要

第三篇
Controlling Robots with the Mind 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一each wire finer than the finest sewing thread一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 from Belle's cap to a box of electronics on a table next to the booth.The box,in turn,was linked to two computers,one next door and the other half a country away. After months of hard work,we were about to test the idea that we could reliably translate the raw electrical activity in a living being's brain一Belle's mere thoughts一into signals that could direct the actions of a robot.We had assembled a multijointed robot arm in this room,away from Belle's view,which she would control for the first time.As soon as Belle's brain sensed a lit spot on the panel,electronics in the box running two real-time mathematical models would rapidly analyze the tiny action potentials produced by her brain cells.Our lab computer would convert the electrical patterns into instructions that would direct the robot arm.Six hundred miles north,in Cambridge,Mass,a different computer would produce the same actions in another robot arm built by Mandayam A. Srinivasan.If we had done everything correctly,the two robot arms would behave as Belle's arm did,at exactly the same time. Finally the moment came.We randomly switched on lights in front of Belle,and she immediately moved her joystick back and forth to correspond to them.Our robot arm moved similarly to Belle's real arm.So did Srinivasan's.Belle and the robots moved in synchrony (同步),like dancers choreographed(设计舞蹈动作)by the electrical impulses sparking in Belle's mind. In the two years since that day,our labs and several others have advanced neuroscience,computer science and microelectronics to create ways for rats,monkeys and eventually humans to control mechanical and electronic machines purely by"thinking through,"or imagining,the motions.Our immediate goal is to help a person who has been unable to move by a neurological(神经的)disorder or spinal cord(脊髓)injury, but whose motor cortex is spared,to operate a wheelchair or a robotic limb. The wires fixed under Belle's cap were connected to 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. [简答题]LBE43197简述中性点不接地系统发生单相接地后的运行情况,并说明该种运行方式的优缺点。
