Looking for the perfect partner

[00:00.65] I'm sure we all remember a time when we fell in love. 我敢肯定，我们都记得我们坠入爱河的时刻。

[00:04.41] For some it was a gradual realisation that the person you knew was actually amazing.对一些人来说，逐渐意识到你认识的人实际上很了不起。

[00:10.18] For others, it was love at first sight – an instant lightning-bolt moment that you knew you'd met your perfect match.对于其他人来说，这是一见钟情——一个瞬间的闪电时刻，你知道你已经遇到了你的完美伴侣。

[00:18.21] What is it that makes someone instantly love someone? 是什么让一个人瞬间爱上一个人？

[00:21.72] Physical attraction is an obvious answer but there are other reasons that can create affection for someone; compatibility, personality and a good sense of humour to name just a few.身体上的吸引力是一个显而易见的答案，但还有其他原因可以让你对某人产生好感；兼容性，个性和良好的幽默感仅举几例。

[00:34.02] But according to one expert, there is a more scientific explanation. 但据一位专家称，有更科学的解释。

[00:39.04] Dr Anna Machin, an Evolutionary Anthropologist at the University of Oxford says men look for signs of fertility and good health in a partner "and the major indicator of that in women is the waist-hip ratio… the absolute ideal." 牛津大学进化人类学家 Anna Machin 博士说，男性在伴侣身​​上寻找生育能力和身体健康的迹象，“而女性的主要指标是腰臀比……绝对理想。”

[00:55.85] This is believed to be 0.7 which is "really your classic hourglass figure."这被认为是 0.7，这是“真正的经典沙漏身材”。

[01:02.12] And what do women look for in men? Well other experts have discovered they look for men who are taller, with broad shoulders and a relatively narrow waist – so a 'V' shaped torso.女人在男人身上寻找什么？好吧，其他专家发现他们寻找更高、肩膀宽、腰部相对较窄的男人——所以是“V”形躯干。

[01:15.42] If you're worried your figure isn't the perfect shape, there could be other factors that will cause someone to fall head over heels in love with you – people also use their sense of smell to sniff out their ideal mate. 如果你担心你的身材不是完美的形状，可能还有其他因素会导致某人爱上你——人们也会用他们的嗅觉来嗅出他们理想的伴侣。

[01:28.46] Apparently, we can detect whether people are genetically different to us by the way they smell.显然，我们可以通过人们闻到的方式来检测人们在基因上是否与我们不同。

[01:35.23] Even if a potential partner's smell is a passion-killer, their facial expressions might make you infatuated with them. 即使潜在伴侣的气味是激情杀手，他们的面部表情也可能让你着迷。

[01:44.03] According to Professor David Perrett, at the School of Psychology and Neuroscience at St Andrews University, "we can change our faces by interacting with others and doing so in a pleasant manner, and that will aid our attractiveness and make others interested in us."根据圣安德鲁斯大学心理学与神经科学学院的大卫·佩雷特教授的说法，“我们可以通过与他人互动并以愉快的方式来改变我们的面孔，这将有助于我们的吸引力，并让其他人对我们感兴趣。”

[02:01.60] So it's good to know there are many reasons why we might be smitten with someone, but there is a problem; will the feeling be mutual and if it is, how long will it last? Nothing is guaranteed and, we know from Shakespeare, the course of true love never ran smoothly!所以很高兴知道我们可能会被某人迷住的原因有很多，但是有一个问题；这种感觉会是相互的吗？如果是，会持续多久？没有什么是可以保证的，我们从莎士比亚那里知道，真爱的过程从来都不是一帆风顺的！
