单项选择题
A pervasive negative attitude of the engineers toward projects funded by his company is the
cause of the delay of signing the contract.
A．perpetual
B．pernicious
C．preventive
D．prevalent
答案
参考答案：D
解析： 本题中，pervasive的意思是“普遍深入的”。D项“prevalent普遍的”符合题意，如：The habit of travelling by aircraft is becoming more prevalent each year.(坐飞机旅行一年比一年普遍了。)其他三项“perpetual永久的；pernicious有害的；preventive预防的”都不正确。
