老师讲到that引导定语从句作介词宾语时,介词不可提到that前,介词后需用which或whom代替是什么意思?
并举例说明,
并举例说明,
如果定语从句中出现把从句中的介词提前到关系代词which和whom之前,这时候关系代词which和whom 作介词宾语时,关系代词不能省,介词提前关系词不能用that .
比如：
This is the pen ( which /that) he wrote his composition with. 在这个句子中which/that可省.
解释：上面这句with介词在后,所以可以用that,或者which,并可省略.
This is the pen with which he wrote his composition.这个句子中 which 就不能省.
解释：上面这句with介词在前,所以不能用that,只能用which（这里指物,所以用which,如果指人,就用whom）
再比如：
I like the boy (whom/that) we played football with.
解释：上面这个介词在后,所以可以whom或者that,并可省略.
I like the boy with whom we played football.
解释：上面这个介词在前,所以不能用that,只能用whom（这里指人,所以用whom,如果指物,就用which）
另外补充知识：
在定语从句中,只能用that引导的情况如下
1、先行词是最高级或被最高级修饰.
This is the most interesting book that l have ever read.
2、先行词是序数词或被序数词修饰.
The second foreign country that l expect to visit is Greek.
3、先行词是不定代词时,如"all、few、little、much、anything、nothing、something"
That’s the only thing that we can do at the moment.
4.、先行词既有人又有物时
比如：
This is the pen ( which /that) he wrote his composition with. 在这个句子中which/that可省.
解释：上面这句with介词在后,所以可以用that,或者which,并可省略.
This is the pen with which he wrote his composition.这个句子中 which 就不能省.
解释：上面这句with介词在前,所以不能用that,只能用which（这里指物,所以用which,如果指人,就用whom）

I like the boy (whom/that) we played football with.

I like the boy with whom we played football.

that作介词宾语从句时,介词不可提到that前,当介词提前时,需要用which或whom来代替.举几个例来让我明白下
that引导的宾语从句作介词的宾语时,that不可省略那为什么会有介词后不用that用which?
关系代词whom,which,that在限制性定语从句中作动词宾语或介词宾语,而该介词由位于从句末尾时才省略,
that 引导定语从句时为什么不能作介词宾语

that引导的宾语从句作介词的宾语时,that不可省略.

关于定语从句定语从句中,用状语作引导词时,可用介词加which,that等代替,怎样选介词呢?when=in/on/at
定语从句中 介词+which或whom
用定语从句：that whik who whom when where why as 介词+which 介词+whom
宾语从句中的引导词指物时且做介词的宾语时用that还是which
