　　孝文帝立，以为太尉勃亲以兵诛吕氏，功多；陈平欲让勃尊位，乃谢病。于是孝文帝乃以绛侯勃为右丞相，位次第一；平徙为左丞相，位次第二。

　　居顷之，孝文皇帝既益明习国家事，朝而问右丞相勃曰：“天下一岁决狱几何？”勃谢曰：“不知。”问：“天下一岁钱谷出入几何？”勃又谢不知，汗出沾背，愧不能对。于是上亦问左丞相平。平曰：“有主者。”上曰：“主者谓谁？”平曰：“陛下即问决狱，责廷尉；问钱谷，责治粟内史。”上曰：“苟各有主者，而君所主者何事也？”平谢曰：“主臣。陛下不知其驽下，使待罪宰相。宰相者，上佐天子理阴阳，顺四时，下育万物之宜，外镇抚四夷诸侯，内亲附百姓，使卿大夫各得任其职焉。”孝文帝乃称善。右丞相大惭，出而让陈平曰：“君独不素教我对！”陈平笑曰：“君居其位，不知其任邪？且陛下即问长安中盗贼数，君欲强对邪？”于是绛侯自知其能不如平远矣。居顷之，绛侯谢病请免相，陈平专为一丞相。（《史记·陈丞相世家》节录）

　　笠翁日：“陈平不对决狱、钱谷之问，论者皆谓能持大体，以大臣不当亲细务也。予谓开千万世堂高帘远之门，而使下情不能土达者，必此言也。盖文帝此问，重民命也，惜民力也。虑有司用刑之滥，以致失入者多，国家费用之繁，以致聚敛者众。为宰相者，正当因其势而利导之，劝之省刑罚，薄税敛，而乃以夸诞之词掩其疏略之过。幸文帝天资充实，不为外物所阻，始终得遂其仁心。万一惑于陈平之言，则三代之治，何由复见于文景之世哉？”（清《笠翁别集》）

B．汉文帝问周勃“天下一岁决狱几何”“天下一岁钱谷出入几何”，周勃都答不上来，弄得汗流浃背，惭愧不已。

C．汉文帝以同样的问题问陈平，陈平却说这样的问题，应该去问具体主管的人员，不是我宰相应该管的。

D．文帝问陈平，既然各有所司，那么你宰相管什么呢？陈平说出一番上佐天子理阴阳，顺四时的话来，文帝称赞他说得好。于是周勃辞职，让陈平专任宰相。

4．对后面李笠翁一段话的认识，不正确的一项是（     ）

A．以锐利的眼光看穿陈平回答的实质是用虚夸不实之词来掩饰其疏略之过？

C．认为文帝问钱谷出入是重民命，问决狱多少是惜民力，是仁爱之心的表现。

D．赞扬文帝天资仁厚，不受陈平之惑，始终得遂其仁心，否则，历史上有名的“文景之治”就不可能出现了。

The Environment in Perspective:Is Everything Getting Steadily Worse Much of the discussion of environmental problems in the popular press leaves the reader with the impression that matters have been growing steadily worse, and that pollution is largely a product of the profit system and modern industrialization. There are environmental problems today that are both enormous and pressing, but in fact pollution is nothing new. Medieval cities were pestholes—the streets and rivers were littered with garbage and the air stank of rotting wastes. At the beginning of the eighteenth century, a German traveler reported that to get a view of London from the tower of St. Paul’s, one had to get there very early in the morning "before the air was full of coal smoke." Since 1960 there has been progress in solving some pollution problems, much of it the result of concerted efforts to protect the environment. The quality of the air in most Canadian cities has improved. In Toronto, for example, the concentration of suspended particulates, or soot, in the air has fallen dramatically since 1962. To put this figure in perspective, it should be noted that the current health advisory level for the index is 32. At a level of 58, people with chronic respiratory diseases may be affected. At 100, even healthy people may be affected by prolonged conditions, and those with cardiac and respiratory diseases could suffer severe effects Recently in Toronto, the index has exceeded 32 on fewer than half a dozen days annually. Similar improvements have occurred elsewhere in Canada and in other industrialized countries. Even the famous, or rather infamous, "fogs" of London are almost a thing of the past. There have been two high readings of particular note in the British capital in 1959 (when the index rose to 275 and there was a 10 percent increase over the normal number of deaths) and in 1962 (when the index rose to 575 and there was a 20 percent increase in mortality ). But more recently, London’s, cleaner air has resulted in an astounding 50 percent increase in the number of hours of winter sunshine. In short, pollution problems are not a uniquely modem phenomenon, nor is every part of the environment deteriorating relentlessly. Environmental problems do not occur exclusively in capitalist economies. For example, in the People’s Republic of China, coal soot from factory smokestacks in Beijing envelops the city in a thick black haze. Similarly, smoke from brown-coal furnaces pollutes the air almost everywhere in Eastern Europe. It has been estimated that a third of Poland’s citizens live in areas of "ecological disaster". The citizens of Leipzig, a major industrial city in what was formerly East Germany, have a life expectancy a full six years shorter than the national average. However, we do not mean to suggest that all is well with the environment in market-oriented economies or that there is nothing more to do. While there have been some improvements, serious problems remain. Our world is now subject to a number of new pollutants, most of which are far more dangerous than those we have reduced, even though they may be less visible and less malodorous While environmental problems are neither new nor confined only to capitalist, industrialized economies, these facts are not legitimate grounds for complacency. The potential damage that we are inflicting on ourselves and on our surroundings is very real and very substantial.
