in which. on which.for which.at which.of whom分别等于什么。例forwhich=why其用法是?

Question

如题所述

Answer 1

没有分别等于什么，具体句子具体对待
比如The room in which I was born remains the same. 这里=where
The day on which I was born is unknown. 这里 on which= when
The year in which i was born is unknown. 这里in which=when
介词选择根据前面名词，或者后面动词来确定， 而关系副词when,where根据前面是时间，还是地点来确定。
你问这个问题，说明你定语从句基本不懂，建议你找点详细资料，好好学学。

Answer 2

供参考

不妨也试试用以下的角色来理解

which 方面

这主要与句中的
(1) 不及物动词所用的介词
或
(2) 或其它的介词
有关

例子
(1) 的例子
John liked the book. Mary was sitting on the book.
留意 sitting 这个不及物动词用了 on 这个介词
如果将这2句用which 来连在一起
on the book 便成为了 on which
John liked the book, on which Mary was sitting.

(2) 的例子
John has a book. In the book there are a lot of pictures.
留意 in the book
连成2句的话
可得出
John has a book in which there are a lot of pictures.

值得留意的是
由於这里的 which 都是跟在介词之後的
所以在原句中是’宾语‘
sitting on the book 中的 book 是宾语
in the book 中的 book 也是宾语

至於whom
概念都是一样
用上 of
因为原句中出现了 of 这个介词
而 whom 也是宾语
不同之处
乃是 whom 指人
which 指非人的生物或物件

例子

There are ten students. Many of them are hardworking.
留意 many of them
many 是主语
of them 中的 them 是介词 of 的宾语
连成一句
得出
There are ten students, many of whom are hardworking.

再看以下的2句

John stared at the girl. He was fond of the girl.
留意 fond of the girl.
连成一句
得出
John stared at the girl, of whom he was fond.

for which = why ?吗

其实for 有 because 之意

单以 for which 来解理
其中一个可能的解释是‘为了这/它...'
这也许可以理解为 why 吧

如果能提供具体的句子
也许能够给点意见

Answer 3

具体情况分析，表示时间的用when 地点用 where 例如和 live连用的时候 the street where I live= the street in which I live,
of whom =Whose

主要是看句子的意思。
