1 D
填where的时候,(where they met in September for the first time) 这部分形成了定语从句,先行词是university,整体在句中作地点状语;
而句子的关键在后面的that,这与前面的 It was in the university...部分构成强调句.
可以说整个句子如果没有(where they met in September for the first time)也是对的.
2 A
考察定语从句及have sth done的用法.
定语从句相当于省略了作宾语的关系词that,指代recorder,还原下为:
Is this the recorder (that) you want to have repaired?
have sth done,这里的sth是被修.
3 B
考察make sth done (to sb)结构,这里的done做宾语补足语.本句中就是known做宾补.
而出题者故意绕个弯,考察你该结构的被动形式,sth be made known (to sb).而这个时候known就相应地被称作主语补足语.
慢慢积累吧.
