【甲】

    臣本布衣,躬耕于南阳,苟全性命于乱世,不求闻达于诸侯。先帝不以臣卑鄙,猥自枉屈,三顾臣于草庐之中,咨臣以当世之事,由是感激,遂许先帝以驱驰。后值倾覆,受任于败军之际,奉命于危难之间,尔来二十有一年矣。

    先帝知臣谨慎,故临崩寄臣以大事也。受命以来,夙夜忧叹,恐托付不效,以伤先帝之明,故五月渡泸,深入不毛。今南方已定,兵甲已足,当奖率三军,北定中原,庶竭驽钝,攘除奸凶,兴复汉室,还于旧都。此臣所以报先帝,而忠陛下之职份也。至于斟酌损益,进尽忠言,则攸之、祎、允之任也。

(节选自诸葛亮《出师表》)

【乙】

    诸葛亮围祁山,南安、天水、安定三郡反应亮。帝遣真督诸军军郿,遣张郃击亮将马谡,大破之。安定民杨条等略吏民保月支城,真进军围之。条谓其众曰:“大将军自来,吾原早降耳。”遂自缚出。三郡皆平。真以亮惩于祁山,后出必从陈仓,乃使将军郝昭、王生守陈仓,治其城。明年春,亮果围陈仓,已有备而不能克。增邑,并前二千九百户。四年,朝洛阳迁大司马赐剑履上殿入朝不趋。真以“蜀连出侵边境,宜遂伐之,数道并入,可大克也。”帝从其计。真当发西讨,帝亲临送。真以八月发长安,从子午道南入。司马宣王溯汉水,当会南郑。诸军或从斜谷道,或从武威入。会大霖雨三十余日,或栈道断绝,诏真还军。真每征行,与将士同劳苦,军赏不足,辄以家财班赐,士卒皆愿为用。真病还洛阳,帝自幸其第省疾。真薨,谥曰元侯。

阅读下列材料,从每题所给的四个选项(A、B、C和D)中,选出最佳选项.

    One of the executives gathered at the Aspen Institute for a day-long leadership workshop using the works of Shakespeare was discussing the role of Brutus in the death of Julius Caesar. “Brutus was not an honorable man,” he said. “He was a traitor(叛徒). And he murdered someone in cold blood.” The agreement was that Brutus had acted with cruelty when other options were available to him. He made a bad decision, they said—at least as it was presented by Shakespeare—to take the lead in murdering Julius Caesar. And though one of the executives acknowledged that Brutus had the good of the republic in mind, Caesar was nevertheless his superior. “You have to endeavor,” the executives said, “our policy is to obey the chain of command.”

    During the last few years, business executives and book writers looking for a new way to advise corporate America have been exploiting Shakespeare’s wisdom for profitable ends. None more so than husband and wife team Kenneth and Carol Adelman, well-known advisers to the White House, who started up a training company called “Movers and Shakespeares”. They are amateur Shakespeare scholars and Shakespeare lovers, and they have combined their passion and their high level contacts into a management training business. They conduct between 30 and 40 workshops annually, focusing on half a dozen different plays, mostly for corporations, but also for government agencies.

    The workshops all take the same form, focusing on a single play as a kind of case study, and using individual scenes as specific lessons. In Julius Caesar , sly provocation(狡诈的挑唆) of Brutus to take up arms against the what was a basis for a discussion of methods of team building and grass roots organism.

    Although neither of the Adelmans is academically trained in literature, the programmes, contain plenty of Shakespeare tradition and background. Their workshop on Henry V, for example, includes a helpful explanation of Henry’s winning strategy at the Battle of Agincourt. But they do come to the text with a few biases (偏向): their reading of Henry V minimizes his misuse of power. Instead, they emphasize the story of the youth who seizes opportunity and becomes a masterful leader. And at the workshop on Caesar, Mr. Adelmans had little good to say about Brutus, saying “the noblest Roman of them all” couldn’t make his mind up about things.

    Many of the participants pointed to very specific elements in the play that they felt related Caesar’s pride, which led to his murder, and Brutus's mistakes in leading the  after the murder, they said, raise vital questions for anyone serving as a business when and how do you resist the boss?
