where which that的用法

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

希望你能成功!!!!!!!!!!!!!!!!!!!

which that都可以引导名词性从句，其中that只能引导宾语从句，对主句的宾语进行说明（即只能代替宾语不能代替主语）

where引导状语从句，表示地点，凡是表示 在哪里 的都可以用where,不管是抽象空间还是具体地点

另外，which前面加介词也可以引导状语从句
如in/at which=where

非谓语从句，where当然代地点，而且只能代地点。
