阅读下面的文言文，完成小题。

苏秦始将连横,说秦惠王曰：“大王之国，田肥美，民殷富，战车万乘，奋击百万，沃野千里，蓄积饶多，地势形便，此所谓天府，天下之雄国也。以大王之贤，士民之众，车骑之用，兵法之教，可以并诸侯，吞天下，称帝而治，愿大王少留意，臣请奏其效。” 

秦王曰：“寡人闻之，毛羽不丰满者不可以高飞；文章不成者不可以诛罚 ，道德不厚者，不可以使民；政教不顺者，不可以烦大臣。今先生俨然不远千里而庭教之，愿以异日。”

说秦王书十上而说不行，黑貂之裘弊，黄金百斤尽，资用乏绝，去秦而归。负书担橐，形容枯槁，面目犁黑，状有愧色。归至家，妻不下纴，嫂不为炊，父母不与言。苏秦喟叹曰：“妻不以我为夫，嫂不以我为叔，父母不以我为子，是皆秦之罪也!”乃夜发书，陈箧数十，得太公《阴符》之谋，伏而诵之，简练以为揣摩。读书欲睡，引锥自刺其股，血流至足，曰：“安有说人主不能出其金玉锦绣，取卿相之尊者乎？”期年揣摩成，日：“此真可以说当世之君矣。”

于是乃摩燕乌集阙①，见说赵王于华屋之下，扺掌而谈，赵王大悦，封为武安君，受相印。革车百乘，锦绣千纯，白璧百双，黄金万溢，以随其后。约从散横，以抑强秦。故苏秦相于赵而关不通。

当此之时，天下之大，万民之众，王侯之威，谋臣之权，皆欲决苏秦之策。当秦之隆，黄金万溢为用，转毂连骑，炫熿②于道，山东之国，从风而服，使赵大重。

将说楚王，路过洛阳，父母闻之，清宫除道，张乐设饮，郊迎三十里。妻侧目而视，倾耳而听；嫂蛇行匍伏，四拜自跪而谢。苏秦曰：“嫂何前倨而后卑也？”嫂曰：“以季子之位尊而多金。苏秦曰嗟乎贫穷则父母不子富贵则亲戚畏惧人生世上势位富贵盖可忽乎哉！”（节选自《战国策 秦策一》）

【注】①燕乌集阙：宫阙名。②炫熿：张扬炫耀。
