问题 SARS, which had affected millions of people throughout the world,______doctors and public health workers at first.

选项 A、complexed
B、duplexed
C、triplexed
D、perplexed

答案 D

解析 动词形似义异辨析。perplex意为“使困惑,使茫然,使费解”,相当于bewilder,puzzle,confuse,如:The question perplexed him.这个问题困扰着。complex表示“把……复杂化”;duplex意为“使成双”;triplex一般作形容词用,表示“三倍的,三重的”,如:a triplex window三层窗。
