《三国演义》(第十一回节选)

    却说曹操正在军中,与诸将议事,人报徐州有战书到。操拆而观之,乃刘备书也。书略曰:备自关外得拜君颜,嗣后(嗣,sì。以后)天各一方,不及趋侍。向者,尊父曹侯,实因张阄(kǎi)不仁,以致被害,非陶恭祖之罪也。目今黄巾遗孽(niè,灾祸),扰乱于外;董卓余党,盘踞于内。愿明公先朝廷之急,而后私仇;撤徐州之兵,以救国难;则徐州幸甚,天下幸甚!曹操看书,大骂:“刘备何人,敢以书来劝我!且中间有讥讽之意!”命斩来使,一面竭力攻城。郭嘉谏(进谏,劝说)曰:“刘备远来救援,先礼后兵,主公当用好言答之,以慢(怠懈)备心,然后进兵攻城,城可破也。”操从其言,款留来使,候发回书。正商议间,忽流星马飞报祸事。操问其故,报说吕布已袭破兖(yǎn)州,进据濮(pú)阳。原来吕布自遭李、郭之乱,逃出武关,去投袁术;术怪吕布反覆不定,拒而不纳。投袁绍,绍纳之,与布共破张燕于常山。布自以为得志,傲慢袁绍手下将士。绍欲杀之。布乃去投张杨,杨纳之。时庞舒在长安城中,私藏吕布妻小,送还吕布。李傕(jué)、郭汜(sì)知之,遂斩庞舒,写书与张杨,教杀吕布。布因弃张杨去投张邈(miǎo)。恰好张邈弟张超引陈宫来见张邈。宫说(shuì,劝说)邈曰:“今天下分崩,英雄并起君以千里之众,而反受制于人,不亦鄙(被人轻视)乎?今曹操征东,兖州空虚;而吕布乃当世勇士,若与之共取兖州,霸业可图也。”张邈大喜,便令吕布袭破兖州,随据濮阳。止有鄄(juàn)城、东阿、范县三处,被荀或(yù)、程昱(yù)设计死守得全,其余俱破。曹仁屡战,皆不能胜,特此告急。操闻报大惊曰:“兖州有失,使吾无家可归矣,不可不亟(jí急)图之!”郭嘉曰:“主公正好卖个人情与刘备,退军去复兖州。”操然(同意)之,即时答书与刘备,拔寨退兵。
