单项选择题
In Hong Kong, doctors reported that, for unclear reasons, 12 recovered SARS patients had ________weeks after they had been discharged — spurring fears that people might be infectious even after they''d left isolation.
A．recovered
B．relapsed
C．reexamined
D．re-diagnosed
答案
参考答案：B
解析：形近识别。四个选项均有前缀re-，但词义各不相同。A．recovered痊愈、复原；B．relapsed(旧病)复发；C．reexamined复试；D．re-diagnosed重新诊断。本句意为：12名痊愈的非典患者在解除隔离后几周——引发恐慌。所以B为答案。
