这个发现或许会改变人们对长期关系的一般预期。

According to the authors, companionship love, which is what many couples see as the natural progression of a successful relationship, may be an unnecessary compromise.

研究者称，虽然伙伴式的爱情在很多夫妇看来是成功爱情关系的自然发展阶段，但它实际上可能是一种不必要的妥协。

"Couples should strive for love with all the trimmings," Acevedo said. "And couples who've been together a long time and wish to get back their romantic edge should know it is an attainable goal that, like most good things in life, requires energy and devotion."

Acevedo说：“夫妻应该努力经营爱情，让它变得更完美。那些结婚多年、希望找回浪漫感觉的夫妇，应该认识到这是完全可以实现的目标。浪漫和生活中绝大多数好东西一样，它需要投入精力才能达成。”
