True love
　　Somewhere amid attraction and sex, we all hope, are strong feelings of love. But which of all the motivations really drives us?
　Interestingly, brain scans in people who'd recently fallen in love reveal more activity related to love than sex. "Romantic love is one of the most powerful of all human experiences," says Helen Fisher, an anthropologist at Rutgers University. "It is definitely more powerful than the sex drive."
　The rules of attraction make up a pretty long list. No scientist knows the order of the list. But near the top is perhaps one of the toughest characteristics to gauge in advance in the search for the perfect partner.　
　　真爱？
　　不论是吸引还是性爱，我们都希望是源于浓浓爱意。不过到底是那个动机最终促使我们行动呢？　　有趣的是，对那些才坠入爱河的人进行的脑部扫描发现，和爱有关的活动比和性有关的更多。“浪漫的爱情是在人类所有的体验中最强烈的一种。”罗特格斯大学的人类学家Helen Fisher说，“它绝对比性冲动要强烈得多。”
　我们可以列出一长串的吸引法则。没有人知道哪个更为重要。不过名列前茅的应该是那些寻找完美伴侣时所提出的要求。
