关于seven-year itch这个词组的意思,在freesearch dictionary里面这样解释：
seven-year itch
noun {U} INFORMAL HUMOROUS
If a married person has the seven-year itch,they are feeling dissatisfied with their marriage after seven years,and are considering having a sexual relationship with someone who is not their wife or husband.
中文里也有“七年之痒”一说,应该就是这个帕来品了.网上搜了一下,发现有人搞笑解释说,“所谓“七年之痒”意思是指：一年新鲜、二年熟悉、三年乏味、四年思考、五年计划、六年蠢动、七年行动.真是挺有意思的.
