Anyone, once tested ________ for the bird flu virus, will receive free medical treatment from our government.
A . positive B . possible C . potential D . proper
A
【详解】考查形容词词义辨析。句意:任何禽流感病毒检测呈阳性的人,都将得到我国政府的免费治疗。 A. positive 阳性的; B. possible 可能的; C. potential 潜在的; D. proper 适当的。根据后文 “will receive free medical treatment from our government” 得到免费治疗可知,是已得禽流感,所以是 positive 检测为阳性符合句意。故选 A 项。
