把下面两个句子合并成含有定语从句的主从复合句（每空一词）
The man is my uncle. The man’s shoes are white.
The man ____ ____ ____ ____ ____ my uncle.

合并后主句部分来自第一句，定语从句部分来自第二句。合并后的先行词是the man，指人，且关系词在定语从句中作定语，所以关系词要用关系代词whose。故从句部分为“whose shoes are white”，放在先行词the man后边。合并后的完整句子为“The man whose shoes are white is my uncle.”。故本题答案为whose shoes are white is。
