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 sch...��ô�������ô������I visited the house��where/which ��my grandparents are still livingyesterday ����ֻ����ν�ɣ��Dz�����which�����ǣ�����Wherelive in ��һ���������ʡ����in����ǰ����in whichin which=where������where�Dz��Ǻ����м��ﶯ�ʾ����������أ����ǡ� ���ﶯ�ʺ�����Ը����������˵���������ﶯ�ʺ�һ������ֱ�Ӹ�����Ҫ�Ӹ���ʡ�
