我认为纸质工具书更易被其电子版取代，而受中国文人喜爱的散文集是最不可能被代替的。

Well,I suppose it doesn't strike me as an implausible thing to say that if everybody in the troop got killed and you would have gotten killed had you been there, but instead,the person you hired to take your place gets killed, then he took your place.

我想可以这么说,如果大家都被杀死，而你若是在战场上也被杀了，但被杀的却是你花钱雇来的人，他就代替了你。
