问题 The professor can hardly find sufficient grounds ______ his argument in favor of the new theory.
选项 A、which to base on
B、on which to base
C、to base on which
D、which to be based on
答案 B
解析 定语从句。这里实际指to base his argument on sufficient grounds。句中使用定语从句的形式，先行词为sufficient grounds，对应的关系代词应该为which或者that，该关系代词在从句中作介词 on的宾语，因此只能用which，不能用that。
