阅读下边两个文言文语段,完成小题。(10分)

【甲】鱼,我所欲也;熊掌,亦我所欲也。二者不可得兼,舍鱼而取熊掌者也。生亦我所欲也;义,亦我所欲也。二者不可得兼,舍生而取义者也。生亦我所欲,所欲有甚于生者,故不为苟得也;死亦我所恶,所恶有甚于死者,故患有所不辟也。如使人之所欲莫甚于生,则凡可以得生者何不用也?使人之所恶莫甚于死者,则凡可以辟患者何不为也?由是则生而有不用也,由是则可以辟患而有不为也。是故所欲有甚于生者,所恶有甚于死者。非独贤者有是心也,人皆有之,贤者能勿丧耳。

一箪食,一豆羹,得之则生,弗得则死。呼尔而与之,行道之人弗受;蹴尔而与之,乞人不屑也。万钟则不辩礼义而受之,万钟于我何加焉!为宫室之美,妻妾之奉,所识穷乏者得我与?乡为身死而不受,今为宫室之美为之;乡为身死而不受,今为妻妾之奉为之;乡为身死而不受,今为所识穷乏者得我而为之:是亦不可以已乎?此之谓失其本心。

【乙】公孙仪①相鲁而嗜鱼,一国尽争买鱼而献之。公孙仪不受。其弟子谏曰:“夫子嗜鱼而不受者,何也?”对曰:“夫唯嗜鱼,故不受也。夫即②受鱼,必有下人③之色;有下人之色,将枉于法;枉于法,则免于相,虽嗜鱼,彼必不能常给我鱼,我又不能自给鱼;即无受鱼而不免于相,虽嗜鱼,我能长自给鱼。”此明夫恃人不如自恃也,明于人之为己者不如己之自为也。         (《韩非子•外储说右下》)                       

注释:①公孙仪:春秋时鲁穆公的相。②即:假如。③下人:迁就他人。
