问题描述：
Is this research center____you visited the modern equipment last year?(C)
A.where B.that C.the one that D.the one where
答
我认为你的答案不对，因为you visited the modern equipment 这句话不缺成分。这题我认为选A或D都是可以的。
当选A时where you visited the modern equipment 作表语
当选D时the one 做先行词，where you visited the modern equipment 做定语
各位看客，去网上查一查吧，很多复习资料上都有这题，而且绝大多数的答案都是D(虽然我认为A也可以）.但C是肯定不行的，这句话中visit不缺宾语，它的宾语是the modern equipment
答
the one 作为先行词，后边that 引导一个定语从句。
答
首先这道题考查的是定语从句where引导定语从句时,是从句中缺少状语时用的,如果先行词是center的话,放入从句应当是visit the center而不是visit in the center所以此处缺的是宾语而非状语,所以A错而选B,以center为先...
答
This research center is the one that you visited the modern equipment last year.
