要点提示:
1. 在正式文体中,关系代词作介词宾语,此时, whom
用于指人, which用于指物. 不可用that.
2. 如果限制性定语从句中的介词置于句末，则关系代
词可以用who (m), which或that，也可以省略。
3. 如果定语从句的谓语动词为“动词+介词”构成的
动词短语，则介词必须后置，不能放在关系代词前面。
Examples
They are the friends with whom I went to the
botanical gardens.

greatest respect.
He only published one book of which this is the
last surviving copy.
I will show you the way to the library from
which I borrowed the novel.
Relative clauses with prepositions and whom or which
We can put a preposition in front of whom or
which at the beginning of a relative clause. This
pattern is rather formal.
This is the plant on which people can stand.
Look at these photographs from your trip to the
countryside. You must explain these photos to a

with whom or which. Follow the example.

1. 关系代词when, where和why可以用于定语从句，
其中when和where既可以用于限制性定语从句，
也可用于非限制性定语从句，而why只能用于限
制性定语从句。如：

was my parents’ 30th wedding anniversary.
The travel agency, where he got all the information
he needed, is just round the corner.
2. 关系代词when, where和why在定语从句中
分别作时间、地点和原因状语。相当于
“介词+关系代词which“。如：
He clearly remembered the days when (=during
which) he conducted the investigation.
That is the travel agency where (=from which)
he got all the information he needed.

relative clauses with why, when
or where after some nouns, as
