The professor could hardly find sufficient grounds_____his arguments in favor of the new theory.
A.on which to base
B.which to base on
C.to base on
D.to be based on
D
[译文]教授几乎找不到足够的理由作为其论据的基础以支持这种新理论。[题解]base sth.on…为固定搭配,[D]中的介词on放于指代sufficient grounds的which前,正常语序应是 to base his arguments on sufficient grounds,因此[D]正确。
