定语从句17. Is this the university _____ you visited last time?

答案：B.本题考查定语从句的关系词.由题干可知,先行词是the university,代入定语从句中为：you visited the university.由此可知,先行词在定语从句中作宾语,且先行词指代“事物”,则关系代词用that、which或省略关系代词that/which.
若将本题改为：Is this university _____ you visited last time?则此处缺少先行词,选项C符合题意.分析此题,将其变为陈述句：This university is ______you visited last time.此时,设空处缺少先行词the university,用the one来代替.
