.You need some facts _______to base your theory.A.where B.on which C.in place where D.in the place选B（这是个定从吗,先行词是facts?which作啥成分?on搭配的短语是啥,那其他选项错哪儿了,
答
答案选择B,Base on是固定搭配.先行词是facts,where引导的是状语从句,后面不直接跟介词,所以A不正确.in the place相当于where,因此答案也不正确.所以选择Bon which在定从中是做状语吗？从句中的主语，谓语又是啥呢其实，这个句子结构可以这样理解。You need something to do是这个句子的主干，主谓宾很明了。在从句中呢，先行词是facts,关系词肯定要用which了，然后再看介词，根据base on 这一固定搭配，答案很清楚。这只是个人意见，仅供参考，谢谢！
