1-7 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. (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 答案是b 但我觉得b有问题,因为they既可以指rabies也可以指前面的victims,虽然可以用语境判断为指rabies,但此题不是犯了指代不明的错误吗?
