Every affair will redefine a marriage, and every marriage will determine what the legacy of the affair will be. Although infidelity has become one of the prime motives for divorce in the West, I’ve seen many couples stay together after the revelation of an affair. I believe the odds are in favor of Priya and Colin’s marriage surviving, but the quality of their future connection will depend on how they metabolize her transgression.

参考译文：每一件事都会重新定义一段婚姻，每一段婚姻都将决定这件事的遗产是什么。虽然不忠已经成为西方离婚的主要动机之一，但在婚外情曝光后，我看到很多夫妻在一起。我相信普里娅和科林的婚姻存续的可能性很大，但他们未来关系的质量将取决于他们如何代谢她的违法行为。

Priya and Colin's marriage surviving 为动名词复合结构“普里娅和科林婚姻存续/婚姻继续存在”作短语介词in favour of 宾语，Priya and Colin's marriage为动名词surviving逻辑主语。
