核心问题
Since I loved her very much when she was alive, I prize my mother's-in-law picture and I wouldn't sell it for all the money in the world.
这道题简直把我弄糊涂了。请分析。
词典解答
我们在plural条中已经指出，复合名词的第一个成分为中心词时，构成复数形式的方法，是把第一个成分变为复数，例如：mother-in-law mothers-in-law stander-by standers-by passer-by passers-by但是，它们构成属格的方法，却不是在第一个中心词上加's，而是在合成词的末尾加's。例如：stander-by stander-by's passer-by passer-by's mother-in-law mother-in-law's somebody else somebody else's(book)(参见grown-ups/mothers-in-law)
