科学家新发现了女性身上的一种“离婚基因”,这种基因可能导致携带者的婚姻充满矛盾和摩擦。携带这种基因变体的妇女,很难与他人建立亲密关系而不太愿意走入婚姻殿堂。即使与他人结为夫妻,她们的婚姻出现摩擦和战争的概率也高达50%。 if a relationship is filled with rows or a marriage comes to an end, men may wonder what went wrong. but scientists say the answer could lie in a woman's 2. for the first time, they have identified a female 'divorce 1' that can predict a rocky marriage and identify women who may struggle to commit to their partner. women who inherit the variation of a common gene are less likely to get married in the first place as they find it harder to bond with other people. but if they do marry, they are 50 per cent more likely to report a troubled relationship filled with 3 4(冲突,争吵) . perhaps unsurprisingly, partners of women with the gene are also more likely to report being unhappy. scientists believe the gene affects how women process the 'cuddle(搂抱,拥抱) 5' oxytocin(催产素) , which is known to promote feelings of love and 6 affection. women produce oxytocin naturally, but particularly during childbirth and while breastfeeding. it helps them bond with their baby. but if women cannot process oxytocin properly, they may not be able to bond normally with other people – including their partners, friends and children. it may even be linked to autism, the researchers say. a swedish team examined the 7 of more than 1,800 women and their partners. each couple had been together for more than five years, and were either married or living together. women who were identified as carrying the variation of the oxytocin receptor gene, described as the a-allele, were 50 per cent more likely to report 'marital crisis or threat of divorce'. men married to these women were also far less satisfied in their relationships. the lead researcher, hasse walum, from stockholm's karolinska institute, said: 'we've found evidence that oxytocin can be involved in the regulation of human pair-bonding by showing that variation in the oxytocin receptor gene is linked to how strongly women bond to a partner.' the same team found the male version of the divorce gene in a study four years ago. it affects how the brain used the chemical vasopressin(加压素) , which in turn affects men's ability to commit and remain faithful. 点击收听单词发音
