参考答案
正确答案:D
解析:本题问“对越南女于的病毒检查暗示了什么?”第一段中第三句提到“testing of virus material from a 23-year- old Vietnamese woman who died of the H5N1 avian flu virus showed no human transmission.”也就是说,对这个死于禽流感的女子身上病毒取样的检测,证实了禽流感还没有在人类中传播。由此可知[D]“尚没有人际传播的证据”正确。[A]“此女从她姐姐那儿感染的病毒”。文中已经提到了“bird flu”不会在人之间传播。[B]“此女的哥哥也感染了禽流感”。文中只说此女子的哥哥“... died of a flu-like illness”,不能肯定他就是得了“bird flu”。[C]“此女子是第一例被证实的禽流感受害者”。文中没有提及。
