同类题4

阅读《出师表》节选，完成文后各题。

先帝创业未半而中道崩殂，今天下三分，益州疲弊，此诚危急存亡之秋也。然侍卫之臣不懈于内，忠志之士忘身于外者，盖追先帝之殊遇，欲报之于陛下也。诚宜开张圣听，以光先帝遗德，恢弘志士之气，不宜妄自菲薄。引喻失义，以塞忠谏之路也。

宫中府中，俱为一体，陟罚臧否，不宜异同。若有作奸犯科及为忠善者，宜付有司论其刑赏，以昭陛下平明之理，不宜偏私，使内外异法也。

侍中、侍郎郭攸之、费祎、董允等，此皆良实，志虑忠纯，是以先帝简拔以遗陛下。愚以为宫中之事，事无大小，悉以咨之，然后施行，必能裨补阙漏，有所广益。

将军向宠，性行淑均，晓畅军事，试用于昔日，先帝称之曰能，是以众议举宠为督。愚以为营中之事，悉以咨之，必能使行阵和睦，优劣得所。

亲贤臣，远小人，此先汉所以兴隆也；亲小人．远贤臣。此后汉所以倾颓也。先帝在时，每与臣论此事，未尝不叹息痛恨于桓、灵也。侍中、尚书、长史、参军，此悉贞良死节之臣，愿陛下亲之信之，则汉室之隆，可计日而待也。
