【题目】WHO declared that the coronavirus outbreak was a global health emergency, _______ that the disease was a risk beyond China.
A.to acknowledgeB.acknowledgingC.acknowledgedD.having acknowledged
在线课程【答案】B
【解析】
考查非谓语动词。句意：WHO宣布冠状病毒的爆发是一个全球健康紧急事件，承认这种疾病的危险超出了中国。分析句子结构可知，此处是非谓语动词作状语，acknowledge和WHO之间是逻辑上的主动关系，故用现在分词acknowledging作状语，故选B项。
