问题 Even today, a century after Pasteur developed the first vaccine, rabies almost always kills its victims unless inoculated in the earliest stages of the disease.

选项 A、its victims unless inoculated
B、its victims unless they are inoculated
C、its victims unless inoculation is done
D、the victims unless there is an inoculation
E、the victims unless inoculated

答案 B

解析 A、E都用了从句的省略形式。从语法分析,unless的主语应是rabies;而从逻辑上讲,unless从句的主语应是victims,违背了省略的第二个条件,因而A、E错。C、D错在inoculation无限定词,导致unless从句的意思与前面的victims似乎没有丝毫联系,不是说对victims进行注射,而是泛泛而谈,句意模糊。B对,they代victims,使得前后的主从关系准确且紧密。
