定语从句中,什么时候用介词+which？

Answer 1

、"介词+关系代词"引导的定语从句

关系代词whom, which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间;当先行词指人时,介词后的关系代词用whom, 其余用which,这时的关系代词不能省略;有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which可用that替换。当介词放在从句有关动词的后面时,关系代词which, that, whom在口语中和非正式文体中经常省略。如:

This is the room in which he used to live. = This is the room (which / that) he used to live in. 这是他过去居住过的房间。

Who's the man with whom you just shook hands? =Who's the man (that / whom) you just shook hands with? 刚才你与他握手的那个人是谁?

但含有介词的短语动词一般不拆开,介词仍放在动词的后面。如:

This is the book (which / that) I'm looking for. 这就是我在找的那本书。

在这类定语从句中,介词的选择一般根据动词的需要,如上述几例,或者根据先行词来决定。如:

There is a mountain of which the top is always covered with snow. 有一座山顶总是覆盖着雪的山。

Answer 2

There is a mountain of which the top is always covered with snow. 有一座山顶总是覆盖着雪的山。 这里的of which是所属关系所以上句是错的　　　　　　　　　　　　要变为there is a mountain,the top of which is always covered with snow

Answer 3

观察下面句子：the
house
which
i
visited
is
beautiful.我参观的房子很美
the
house
in
which
i
live
is
beautiful.我住的房子很美。
都是定语从句，先行词是名词或者代词，第一句用which，第二句用in
which，主要的原因在于从句谓语.
visit
sp.
visit是及物动词，visit
the
house
即可，which指代先行词the
house.
而第二句，live
不及物，表达方式应为live
in
the
house
所以变为live
in
which，
in
which
提前就变成这样了。
另外还有些，
譬如the
reason
why
(=for
which)
i
am
late
is
.....
----i
am
late
for
the
reason（which=the
reason）.
为了这个原因我迟了。
the
factory
where
(=in
which)
i
worked
is
big.
work
in
the
factory
the
spring
festival,
when
(=during
which)
all
the
family
members
will
get
together,
is
wonderful.
---members
will
get
together
during
the
festival.
介词一定要加，不然句子不通。
同理，where,
when,
why=介词+
which
不知道你懂没
