Question

The teacher disussed with Jim,________ problems was poor study habits．

1. A.
   one of which
2. B.
   one of whose
3. C.
   where
4. D.
   who's

Answer 1

B
按照思维定势A、C是最大的干扰项。选择whose，则应把题干中的was改为were；选择one of which,which不能指代先行词Jim，因此选B．one of whose problems相当于one of Jim's problems，谓语动词用单数。这道题立意新颖，情景真实自然。
