在定语从句中which:代替物,在从句中可以做主语,也可以做宾语,做宾语时可以省略,也可以代替整个句子.
that:既可以代替物,也可以代替人.在从句中可以做主语和宾语,做宾语时可以省略.
区别：两者在引导定语从句修饰“物”时,一般没有区别.不可相互替换的情况：
（一）、只能用that的情况：
1、先行词（用定于从句修饰的词,基本上就是which或that前面那个词）是不定代词all,few,little,much,something,nothing,anything,none,one等.例：As we all know,all/something that can be done has been done.
2、先行词被all,any,every,eavh,few,little,no,some等修饰.例：I have read all the books that you gave me.
3、先行词被序数词或形容词最高级修饰.
4、先行词被the only,the very,the same,the last修饰.
5、先行词即有人又有物.
6、在一who,which开头的疑问句中,用that避免重复
7、that不能用于非限定性定语从句中,既逗号后面第一个绝对不会是that.
（二）、只能用which
1、引导非限定性定语从句,既“,”后面用which.
2、用于介词（in,of等）后面,跟介词一起引导定语从句.
所以 in that 基本不会用于引导定语从句,至于which前面有没有in 要看后面的方位名词和动词需不需要介词了.例：This is the factory in which my father worked.因为对于后面定语从句部分来说My father worked in this factory.意思才是完整的,所以 in 不能省略.但跟这一句的表达效果是一样的：This is the factory which my father worked in.就是把介词搬到那个动词后面就好了
