阅读下面语段，完成小题。

       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，故患有所不避也。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，则凡可以避患者何不为也？由是则生而有不用也；由是则可以避患而有不为也。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。

       万钟则不辨礼义而受之；万钟于我何加焉!为宫室之美，妻妾之奉，所识穷乏者得我欤？向为身死而不受，今为宫室之美为之；向为身死而不受，今为妻妾之奉为之；向为身死而不受，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。
