问题 Examination on virus from the Vietnamese woman implied that ______.
The 23-year-old Vietnam woman is the first possible instance of human-to-human transmission, because______.
选项 A、her family got the same disease
B、she is the first case announced
C、she got a flu-like illness and died
D、her brother’s body isn’t available for investigation
答案A
解析 本题问“为什么说此越南女子可能是首例人际传播?”根据题干“the first instance of”可定位相应部分在文中第一段：“Who has today received the results from a study of virus isolated from a 23-year-old woman who is part of a family cluster in Vietnam under investigation as the first possible instance of human-to-human transmission”。也就是说，这个越南女子的家人也患了同样的病(a family cluster)，而专家们正是把她作为首例人际传播的可能病例来调查的。故[A]“她的家人得过相同的疾病”正确。[B]“她是被公布的第一个病例”。文章中没有明确的说，她就是第一例公布的病例。[C]“她得了像禽流毒的病死?”。这里所说的应该是该越南女子的兄弟，而不是她自己。[D]“她兄弟的尸体没有用来做调查”。情况属实，但是它与本题所问不相干。
