The passions of love and pride are often found in the same individual, but having little in common, they mutually ______, not to say destroy, each other.
【正确答案】
D
【答案解析】-方程等号：not to say甚至，表示递进。 - 强词和对应：they指代passions of love and pride。 not to say表示递进，因此空格要填一个负向词，但强度要低于destroy。 reinforce加强，annihilate毁灭，enhance加强，weaken削弱，embrace接受。B的程度和destroy类似，排除。答案选D。
