在职攻硕英语考试

【单选题】The professor can hardly find sufficient grounds ______ his argument in favour of the new theory.
A．which to base on
B．on which to base
C．to base on which
D．which to be based on

网考网参考答案：B
网考网解析：
句中which的先行词是grounds，不定式to base的逻辑主语是the professor，base是及物动词，全句相当于The professor can hardly find sufficient grounds on which he bases his argument in favor of the new theory. base...on(the)grounds“以……为依据建立……”。因此，无论从逻辑上还是从语义上讲，A、C、D都是不通的。另外，which是介词on的宾语，应紧跟该介词，从这个意义上讲，也应选B。 查看试题解析出处>>
