题目内容
5.A human case of H7N9was reported in 2014when a woman______ to be infected with the bird flu virus.( )A. | confirmed | B. | had been confirmed | ||
C. | was confirmed | D. | have confirmed |
分析 2014年一位女性被确诊感染了禽流感病毒,一例人类感染H7N9病毒的案例被报道了出来.
解答 答案:C.
when引导的时间状语从句就是指的in 2014,所以应该是一般过去时,a woman与confirm之间为逻辑上的动宾关系,所以用被动语态,可排除A和D;文中体现不出过去的过去这一时间点,可排除B项;be infected with被感染;故选C.
点评 此题考查一般过去时的被动结构,做题时一定要联系上下文的语境并抓住关键词仔细揣摩时态的选用,并要认真分析句子的逻辑关系,确定主被动结构的用法.
