单选题 Our times seem especially______to bad ideas, probably because in throwing off the shackles of tradition, we have ended up being quite vulnerable to untested theories and untried remedies.
【正确答案】 A
【答案解析】解析：A项impervious“不受影响的”；B项hostile“敌对的”；C项hospitable“热情友好的”；D项prone“易于……的”。本题的答案应表示对bad ideas的态度，从后面的句意可知，前半句应表示能接受坏思想，才能达到后面不受影响的境界。故选A。
