—How did you get in touch with the travel agent,Robin?
—Oh,that’s easy.I surfed the Internet and then called one ________ the telephone
number is provided.
A.which B.in which
C.of which D.whose
答
C
后面定语从句
the telephone number of which = whose telephone number.
因为有了the ,所以就不用用whose了.排除D
而要表示“的”这个从属关系,必须要介词,排除A.
B 和 C 想必很容易看出 C才能表示 “的”
最后 C只是简单颠倒了下the telephone number of which 的顺序
