——Where did Mary's parents buy the beautiful vase?
——It was in the same village 【where】 they spent their hoildays last year.
首先,这个题答案应该是【where】!
其次,解决关键：
① 弄清题型特点：交际性试题,必须注意【题干信息的帮助和限制作用】,不能撇开所提供信息·做回答.
该题第一句话显然强调【Where】,即：【在哪里】玛丽的父母购买了这个美丽的花瓶?所以,回答句重点是针对此信息进行表述.
②第二句内容和结构判断技巧：
It was in the same village 【 】 they spent their hoildays last year (【that】they bought the beautiful vase.结合上句,补全省略成分)
这样可知,前面应该是【定语从句】；再用【还原法】,确定关系词——
They spent holiday【in the village】,表明,【先行词是从句谓语动词spent的地点状语】,用关系副词where.
