李丰，字安国，故卫尉李义子也。黄初中，以父任召随军。始为白衣时，年十七八，在邺下名为清白，识别人物，海内翕然，莫不注意。后随军在许昌，声称日隆。其父不愿其然，遂令闭门，敕使断客。初，明帝在东宫，丰在文学中。及即尊位，得吴降人，问：“江东闻中国名士为谁？”降人云：“闻有李安国者。”是时丰为黄门郎，明帝问左右安国所在，左右以丰对。帝曰：“丰名乃被于吴越邪？”后转骑都尉、给事中。帝崩后，为永宁太仆，以名过其实，能用少也。

正始中，迁侍中尚书仆射。丰在台省，常多托疾，时台制，疾满百日当解禄。丰疾未满数十日，辄暂起，已复卧，如是数岁。初，丰子韬以选尚公主，丰虽外辞之，内不甚惮也。丰弟翼及伟，仕数岁间，并历郡守，丰尝于人中显诫二弟。及司马宣王久病，伟为二千石，荒于酒，乱新平、扶风二郡而丰不召，众人以为恃宠。

曹爽专政，丰依违二公间，无有适莫，故于时有谤书曰：“曹爽之势热如汤，太傅父子冷如浆，李丰兄弟如游光。”其意以为丰虽外示清净，而内图事，有似于游光也。及宣王奏诛爽，住车阙下，与丰相闻，丰怖，遽气索，足委地不能起。

至嘉平四年宣王终后，中书令缺，大 * * 谘问朝臣：“谁可补者？”或指向丰。丰虽知此非显选，而自以连婚国家，思附至尊，因伏不辞，遂奏用之。丰为中书二岁，帝比每独召与语，不知所说。景王知其议己，请丰，丰不以实告，乃杀之。其事秘。

丰前后仕历二朝，不以家计为意，仰俸廪而已。韬虽尚公主，丰常约敕不得有所侵取，时得赐钱帛，辄以外施亲族；及得赐宫人，多与子弟，而丰皆以与诸外甥。及死后，有司籍其家，家无馀积。

参考译文

李丰，字安国，死去的卫尉李义的儿子。黄初年间，凭借父亲的官职征召随军。李丰起初为平民时，年龄十七八岁，在邺下名声清白，擅长品鉴人物，天下一致称颂，没有人不关注他。后来随军到了许昌，声名一天比一天大。他的父亲不希望他这样，就让他闭门谢客。当初，魏明帝还是太子时，李丰正在读书学习。等到魏明帝即位，捉到一个吴国投降的人，问他：“在江东听到魏国的名士是谁？”投降的人说：“听说有个叫李安国的人。”这时李丰担任黄门郎，魏明帝问左右臣子“安国”在哪里，左右臣子用“李丰”来回答。明帝说：“难道李丰的名声遍布于吴越一带吗？”李丰后来调动担任骑都尉、给事中。明帝驾崩后，李丰担任永宁太仆，因为名声超过实际，能够重用他的人很少。

正始年间，李丰升迁为侍中尚书仆射。李丰在中书省，经常托称身体有病，当时中书省的惯例，生病满一百天就应当停发俸禄。李丰生病不到几十天，就暂时起来，不久又重新卧床，像这样好几年。起初，李丰的儿子李韬被选中娶公主为妻，李丰虽然表面上推辞，而内心不怎么害怕。李丰的弟弟李翼、李伟，担任官职几年间，曾一起做过郡守，李丰曾经在很多人面前公开警告两个弟弟。等到司马懿生病日久，李伟担任郡守，放纵饮酒，使新平、扶风两郡治理败乱，但李丰没有召请他，众人认为李伟是恃宠而骄。

曹爽专权，李丰在曹爽和司马懿之间迟疑不决，无所适从，所以当时有诽谤信说：“曹爽气势炎热如沸水，司马懿父子冰冷如凉水，李丰兄弟如飘荡的光。”那意思是认为李丰虽表面上心境洁净，但内心却图谋政事，好像飘荡的光一样捉摸不定。等到司马懿上书诛杀曹爽，车子停在宫殿上，这个消息被李丰听到，李丰非常害怕，于是昏厥过去，两脚拖垂在地上不能起来。

到了嘉平四年司马懿死后，中书令一职空缺，大 * * 征询朝臣意见：“合适补任的人为谁？”有人推荐李丰。李丰虽然知道这不是显要的职位，但认为自己和皇族联姻，想依附皇上的权势，就顺从没有推辞，于是上奏请求任用自己。李丰担任中书令两年，皇上和他特别亲近，常常单独召见他与他说话，别人不知道谈话内容。景王知道他们谈话议论自己，要求李丰说出来，李丰没把实话告诉他，景王于是杀死了他。这件事非常秘密。

李丰先后在魏、晋两朝为官，不把家庭生计放在心上，仅依赖国家俸禄罢了。李韬虽然与公主成婚，李丰经常约束告诫他不能侵占公主的财产，李丰时时得到皇上赐给的钱帛，就把这些送给亲戚族人；等到皇上赏赐给大臣宫女，大臣们大多把宫女赏赐给族中子弟，但李丰都把她们送给了外甥们。等到李丰死后，有关部门没收他的家产，家中没有多余的积蓄。

Robots have been the stuff of science fiction for so long that it is surprisingly hard to see them as the stuff of management fact. A Czech playwright, Karel Capek, gave them their name in 1920 (from the Slavonic word for "work"). An American writer, Isaac Asimov, confronted them with their most memorable dilemmas. Hollywood turned them into superheroes and supervillains. When some film critics drew up lists of Hollywood’s 50 greatest good guys and 50 greatest haddies, the only character to appear on both lists was a robot, the Terminator.
It is time for management thinkers to catch up with science-fiction writers. Robots have been doing menial jobs on production lines since the 1960s. The world already has more than 1m industrial robots. There is now an acceleration in the rates at which they are becoming both cleverer and cheaper: an explosive combination. Robots are learning to interact with the world around them. Their ability to see things is getting ever closer to that of humans, as is their capacity to ingest information and act on it. Tomorrow’s robots will increasingly take on delicate, complex tasks. And instead of being imprisoned in cages to stop them colliding with people and machines, they will he free to wander.

America’s armed forces have blazed a trail here. They now have no fewer than 12,000 robots serving in their ranks. Peter Singer, of the Brookings Institution, a think-tank, says mankind’s 5,000-year monopoly on the fighting of war is breaking down. Recent additions to the battlefield include tiny "insects" that perform reconnaissance missions and giant "dogs" to terrify foes.
But the civilian world cannot he far behind. Who better to unclog sewers or suck up nuclear waste than these remarkahle machines The Japanese have made surprisingly little use of robots to clear up after the recent earthquake, given their world leadership in this area. They say that they had the wrong sort of robots in the wrong places. But they have issued a global call for robotic assistance and are likely to put more robots to work shortly.As robots advance into the service industries they are starting to look less like machines and more like living creatures. The Paro (made by AIST, a Japanese research agency) is shaped like a baby seal and responds to attention. Honda’s robot, ASIMO, is humanoid and can walk, talk and respond to command.
Until now executives have largely ignored robots, regarding them as an engineering rather than a management problem. This cannot go on: robots are becoming too powerful and ubiquitous. Companies may need to rethink their strategies as they gain access to these new sorts of workers. Chinese certainly need to rethink their human-resources policies--starting by questioning whether they should have departments devoted to purely human resources.
The first issue is how to manage the robots themselves. Asimov laid down the basic rule in 1942: no robot should harm a human. This rule has been reinforced by recent technological improvements: robots are now much more sensitive to their surroundings and can be instructed to avoid hitting people. But the Pentagon’s plans make all this a bit more complicated: many of its robots will be, in essence, killing machines.A second question is how to manage the homo side of homo-roho relations. Workers have always worried that new technologies will take away their livelihoods. That worry takes on a particularly intense form when the machines come with a human face: Capek’ s play that gave robots their name depicted a world in which they initially brought lots of benefits hut eventually led to mass unemployment and discontent. Now, the arrival of increasingly humanoid automatons in workplaces, in an era of high unemployment, is bound to provoke a reaction.
So, companies will need to work hard to persuade workers that robots are productivity- enhancers, not just job-eating aliens. They need to show employees that the robot sitting alongside them can be more of a helpmate than a threat. Audi has been particularly successful in introducing industrial robots because the carmaker asked workers to identify areas where robots could improve performance and then gave those workers jobs overseeing the robots. Employers also need to explain that robots can help preserve manufacturing jobs in the rich world.
These two principles--don’t let robots hurt or frighten people--are relatively simple. Robot scientists are tackling more complicated problems as robots become more sophisticated. They are keen to avoid hierarchies among rescue-robots (because the loss of the leader would render the rest redundant). So they are using game theory to make sure the robots can communicate with each other in egalitarian ways. They are keen to avoid duplication between robots and their human handlers. So they are producing more complicated mathematical formulae in order that robots can constantly adjust themselves to human intentions. This suggests that the world could be on the verge of a great management revolution: making robots behave like humans rather than the 20th century’s preferred option, making humans behave like robots.1.Why does the author mention the Czech playwright Karel Capek and the American writer Isaac Asimovg, What is the relationship between science fiction and robot
