现代文阅读

       白求恩同志毫不利己专门利人的精神，表现在他对工作的极端的负责任，对同志对人民的极端的热忱。每个共产党员都要学习他。不少的人对工作不负责任，拈轻怕重，把重担子推给人家，自己挑轻的。一事当前，先替自己打算，然后再替别人打算。出了一点力就觉得了不起，喜欢自吹，生怕人家不知道。对同志对人民不是满腔热忱，而是冷冷清清，漠不关心，麻木不仁。这种人其实不是共产党员，至少不能算一个纯粹的共产党员。从前线回来的人说到白求恩，没有一个不佩服，没有一个不为他的精神所感动。晋察冀边区的军民，凡亲身受过白求恩医生的治疗和亲眼看过白求恩医生的工作的，无不为之感动。每一个共产党员，一定要学习白求恩同志的这种真正共产主义者的精神。

       白求恩同志是个医生，他以医疗为职业，对技术精益求精；在整个八路军医务系统中，他的医术是很高明的。这对于一班见异思迁的人，对于一班鄙薄技术工作以为不足道、以为无出路的人，也是一个极好的教训。
