请问在英语定语从句中如何快速判断出引导词该用where还是that?,也就是怎样判断先行词做宾语还是地点状语?

定语从句要学好一定要会分析从句句子成分,that属于关系代词,当从句中缺主语宾语时可以选用
that,where是关系副词,在从句中做地点状语,从句中不缺必要成分.
this is the school____I visited last week.
this is the school ____I had a meeting last week.
例子比较简单,第一个句子中,visit是及物动词,所以从句中缺宾语,那么先行词school在句子中
作宾语,补全是I visited the school last week,所以可以选that
第二个句子中 I had a meeting主谓宾,句子成分齐全,所以不缺,那么school是表地点的做地点状
语,补全可以是i had a meeting in the school,所以用关系副词where,相当于in which
望采纳,谢谢!（PS:非本人做）

where作状语，句子中无任何成分，that就不行了
