that?where英语定语从句中什么时候用WHERE,什么时候用 THAtI want to go to the pl

很简单
一共分两部
1.判断哪个是先行词
例.You should stand in the place where you were just now
place 是先行词
(怎么判断先行词呢?就看句子里修饰的部分
place ,school,home,等等都指地点,出现有地点的词都要用where; 还有指时间的哦)
2.判断在句中成分
例.You should stand in the place where you were just now
(where you were just now)就是重句
(注意,如果重句里有介词,如where you were in就不能用where只能用that
如果主句里有介词 You should stand in the place in____you were just now
就只能用which)
这是规律自己多看看句子
实在不行问老师
