  1)The 3 yuan for which I bought the book was borrowed from my friend.

  2)Smith,from whom we've learned a great deal,is an old worker.

  根据先行词与介词的某种习惯搭配。如:

  His bag,in which she put all her books,has not been found.

  根据从句中动词与先行词的逻辑关系。如:

  1)This colorless gas is called oxygen,without which we could not live.

  2)This colorless gas is called oxygen,with which we can rescue patients.

  3.定语从句中介词的位置:

  在书面语中,介词多放在关系代词之前,口语中多放在后面。如:

  1)This is the man to whom you spoke.(书面语)

  2)This is the man who/whom you spoke to.(口语)

  在限制性定语从句中,介词可放在关系代词之前或之后;在非限制性定语从句中,介词一般放在关系代词之前。

  介词如果是定语从句中短语动词的固定部分,要放在动词之后,多半不拆开用。如:

  Is this the book which he was looking for?(不可将for放在which之前)

  如果介词是由句中先行词决定的,还是放在关系代词之前为好。如:

  The speed at which light travels is 300 000 km per second.

  "介词+关系代词"作定语时,介词不能后置。如:

  I live in a room,the window of which opens to the south.

  当介词位于定语从句的末尾时,可用that替代which 或whom,也可用who替代whom。且常省略关系代词。如:

  1)This is the pen(that/which) he wrote the letter with.

  2)The doctor(that/who/whom) she sent her friend to is very well known.

  4.whose 可转换为"of+关系代词"的结构。如:

  They live in a house whose door opens to the south.

  →They live in a house of which the door opens to the south.

  →They live in a house the door of which opens to the south.

  5.关系副词when,where,why和"介词+which"可相互代替。如:

  when=in/on/at...+which,where=in/on/at...+which,why=for which。

  1)I won't forget the date when(=on which) I was born.

  2)This is the room where(=in which) I lived.

  3)I don't know the reason why(=for which) he hasn't come today.
