Questions 63 t0 67 are based on the following passage:The Last Supper is a late 15th-century mural painting by Leonardo da Vinci in the refectory of the Convent of Santa Maria della Grazie, Milan. The work is presumed to have been commenced around 1495 and was commissioned as part of a scheme of renovations to the church and its convent buildings by Leonardo’s patron Ludovico Sforza, Duke of Milan. The painting represents the scene of The Last Supper of Jesus with his disciples, as it is told in the Gospel of John. Leonardo has depicted the consternation that occurred among the Twelve Disciples when Jesus announced that one of them would betray him. The Last Supper measures 460cm x880cm and covers an end wall of the dining hall at the monastery of Santa Maria delle Grazie in Milan, Italy. The theme was a traditional one for refectories, although the room was not a refectory at the time that Leonardo painted it. The main church building had only recently been completed (in 1498), but was remodeled by Bramante, hired by Ludovico Sforza to build a Sforza family mausoleum. The painting was commissioned by Sforza to be the centerpiece of the mausoleum. The lunettes above the main painting, formed by the triple arched ceiling of the refectory, are painted with Sforza coats-of-arms. The opposite wall of the refectory is covered by the Crucifixionfresco by Giovanni Donato da Montorfano, to which Leonardo added figures of the Sforza family in tempera.Leonardo began work on The Last Supper in 1495 and completed it in 1498-he did not work on the painting continuously. The beginning date is not certain; as the archives of the convent for the period have been destroyed and a document dated 1497 indicates that the painting was nearly completed at that date. One story goes that a prior from the monastery complained to Leonardo about the delay, enraging him. He wrote to the head of the monastery, explaining he had been struggling to find the perfect villainous face for Judas, and that if he could not find a face corresponding with what he had in mind, he would use the features of the prior who complained.In common with other depictions of The Last Supper from this period. Leonardo seats the diners on one side of the table, so that none of them have their backs to the viewer. Most previous depictions excluded Judas by placing him alone on the opposite side of the table from the other eleven disciples and Jesus or placing halos around all the disciples except Judas. Leonardo instead has Judas lean back into shadow. Jesus is predicting that his betrayer will take the bread at the same time he does to Saints Thomas and James to his left, who react in horror as Jesus points with his left hand to a piece of bread before them. Distracted by the conversation between John and Peter, Judas reaches for a different piece of bread not noticing Jesus too stretching out with his right hand towards it. The angles and lighting draw attention to Jesus, whose head is located at the vanishing point for all perspective lines. The painting contains several references to the number 3, which represents the Christian belief in the Holy Trinity. The Apostles are seated in groupings of three; there are three windows behind Jesus; and the shape of Jesus’ figure resembles a triangle. There may have been other references that have since been lost as the painting deteriorated.

一)人身伤亡事故

1995年3月16日,某供电公司110kV变电站停电进行预防性试验。该站的35kV系统是双母线带旁路接线方式,当天由邻近变电站通过一条35kV线路反送电给该站作站用电源。所以当天该站110kV部分和主变虽已停电,但35kV系统的322-5和332-3两个刀闸还是带电的。当值长和一位值班员正在填写35kV#3母线封地线的操作票时,另一名值班员却擅自拿了地线爬到332-3刀闸上去挂地线,当即发生触电,烧伤面积达92%,幸经尽力抢救,保住了性命。
