| If someone accidentally steps on your
toe, it hurts. But does it hurt more if you think he did it deliberately That,
in essence, is the question Kurt Gray and Daniel Wegner of Harvard University
asked in a study they have just published in Psychological Science. And their
answer is that it probably does. Dr. Gray and Dr. Wegner did not actually step on people’s toes as part of their experiments. But they did arrange for them to receive electric shocks. Altogether, they induced a group of 43 students to participate with offers of academic credits or, failing that, cold cash. On the day of the experiment, each participant was introduced to a study partner, whom he was told was another student participant but who was in fact an assistant of the two researchers. The students were then told about a number of tasks, whi A. To study whether the deliberate hurt hurts more. B. To let people know deliberately hurting people is evil. C. To study the phenomenon of stepping on people. D. To offer students academic credits. [简答题]与带电线路平行、邻近或交叉跨越的线路停电检修，应采取哪些措施防止误登杆塔？
