Question

of which 的用法？

2、I bought a new dictionary, __c__ is very beautiful.
A. whose the cover
B. of which cover
C. the cover of which
D. which cover
答案是c。为什么不能选b？

Answer 1

关系代词which引导的定语从句，
指物，在从句中可以作主语、宾语等。多数情况下，可与that互换。但是要注意当从句中，介词提前只能用which，而且，在非限制性定语从句中，which引导的句子单独翻译为一句话。

Answer 2

你这个句子的which是代指上文的内容，of表示从属关系。其实吧语言是用来交流的，不用扣那么死！如果是考单选，凭语感就OK了！

Answer 3

the cover of (the dictionary--用which代替，非限制性定语从句

Answer 4

选B 的话，应该改成whoes cover，whose指代dictionary

Answer 5

A
of　表示整体当中的一部分。about
900
of
which在这里可以换成of
which
about
900。因为介词+关系代词可以引导定语从句。
如果表示的是所属关系，则有四种说法。如：
The
house
whose
window
faces
south
is
beautiful.
窗户朝南的这栋房子很漂亮。
＝The
house
the
window
of
which
faces
south
is
beautiful.
=
The
house
of
which
the
window
faces
south
is
beautiful.
=The
house
which
the
window
of
faces
south
is
beautiful.
