【题目】When______ to danger and conflict, men tend to increase blood pressure, ______nervous or anxious.
A. exposed; felt B. exposing; felt
C. exposed; feeling D. exposing; feeling
在线课程【答案】C
【解析】
试题分析：考查省略和非谓语动词。句意：当面对危险和冲突时，人们往往血压升高，感到紧张或焦虑。be exposed to 暴露，句子主语是 men，故省略 men are；第二空men 与 feel 之间是主谓关系，故用现在分词形式。故选C。
