sandy's skirt is much more beautiful than my sister's and kate's 这个表达对吗还是MY SISTER AND KATE'S

问题描述:

sandy's skirt is much more beautiful than my sister's and kate's 这个表达对吗
还是MY SISTER AND KATE'S

正确
Snady's skirt is much more beautiful than my sister's (skirt) and kate's (skirt).
句子意思:Sandy的裙子比我姐姐的和Kate的要漂亮得多

MY SISTER AND KATE'S

对的
因为skirt不是两人共有的,所以要分别打'加s
比如:A、B为同一父亲的姐妹,说“她们的爸爸”时就是A and B's
