1.此题考查的是定语从句的关系代词或关系副词的选择
2.选择关系代词还是关系副词的方法：
1）先找先行词
2）判断先行词在从句中充当什么成分
3）如果在从句中做主语,宾语或表语,选择关系代词 which that who whom等
在从句中做定语,选whose
在从句中做状语,选关系副词when,where,why
3.就此题分析：先行词是city 在从句中做了动词 Ivisited 的宾语 或者说从句缺宾语,
所以使用关系代词做宾语,因为city指的是城市,所以用which 或that
写成完整的从句应该是I visited the city 10 years ago.
4.另外：在定语从句中,作宾语的关系代词可以省略,所以此处也可以不填,（省略关系代词）.
5.where 要在先行词在从句中做地点状语时,或者说从句的主干成分不缺时才使用.
比如：Great changes have taken place in the city __ I spent my childhood.
在这个例句中,先行词仍然是city,但是从句主谓宾结构是完整的,先行词city在从句中做了地点状语,所以使用关系副词where（=in which）
写成完整的从句应该是 I spent my childhood in the city.
把这两个例句分析比较一下就会清楚的.祝你学习愉快!
