解析：通过分析句子结构，可知这个句子中包含一个强调句和一个定语从句。首先第一个空需要填一个关系词，因为从句是对前面的名词进行修饰，所以判断出它是一个定语从句，且关系词在从句中作主语，且指物，所以用which；题目中含有It was，出现这样的结构，首先要考虑它是不是强调句。如果把这种句型结构划掉后，应该是一个完整无缺的句子；这也是判断强调句型与其它从句的方法。假设它是强调句，去掉it was和空格处，剩下的句子经过调整语序后变成he spent his childhood in the small house which was built with stones.经过调整语序是一个完整的句子，所以是强调句型，对地点状语进行强调。强调句的结构It is/was+被强调部分 + that + 句子的其他成分，如果被强调的部分是人，可以用who代替that。
