The seven year itch is the psychological theory that happiness in couples starts to deteriorate after seven years together, increasing the chances of a break-up.

心理学认为七年之痒是幸福夫妻在七年的相处之后关系开始恶化，并且可能导致关系破裂的一道坎。

The phrase became world-famous after Marilyn Monroe starred in a film of the same name in 1955, where she plays an attractive actress who becomes the focus of a married man's affections.

这个词语在1955年玛丽莲·梦露(Marilyn Monroe)主演的同名电影后闻名于世。在该片中，梦露饰演了一位被已婚男子深深着迷的富有魅力的女演员。

But new research shows that psychologists got it wrong - the point in a marriage when a couple is most unhappy, therefore most likely to stray, is actually the ten-year mark.

但是新的研究证明心理学家们搞错了——在婚姻中，一对夫妻相处最不愉快也最容易关系破裂的时间是第十年。

A study involving more than 2000 women born between 1957 and 1964 questioned their feelings about their marriage over 35 years.

该项研究由超过2000名出生于1957和1964年之间的妇女共同参与，主要询问她们关于在逾35年的婚姻生活中的感受。

During the interviews, students at Brigham Young University in Utah found that in two thirds of marriages, happiness started at high levels but then steadily declined.

在采访中，来自美国犹他州(Utah)杨百翰大学(Brigham Young University)的学生们发现三分之二的婚姻在刚开始时幸福值很高，但是之后就逐渐下降了。

Women revealed themselves to be most unhappy in their relationships after ten years together.

妇女们透露她们在婚姻关系中最不愉快的时期是相处十年之后。

Researchers suggest that this point coincides with when the females are juggling the biggest workloads both in household chores and childcare.

研究人员认为这一时期也正好与女性最忙碌的时期相吻合。在此阶段，女性面临沉重的负担，一边要处理家务一边还要照顾小孩。

But these levels of discord are short-lived, just five years later, women began to argue much less with their partners.

不过这种不和谐是短暂的，再过五年，女性和丈夫的争吵又会大大减少。

Those who managed to stay together for more than three decades found that their levels of happiness began to grow again, although for most it never reached the same levels as when they first got married.

那些成功与同伴在一起超过30年的女性发现她们的幸福水平又重新开始增长起来了，虽然这无法达到她们刚结婚时的水平。

Couples at this stage in their relationship also argued less than they had at any point in their marriage.

处于该阶段的夫妻的争吵量要比婚姻中的任何一阶段都要少。

The researchers linked this upwards turn in emotion with the point when a couple's children reached the age of financial independence.

研究人员认为这一时间段感情升温的原因与他们的子女达到了经济独立的年纪有关联。
