(·高考辽宁卷)To her joy，Della earned first the trust of her students and then of her colleagues.

A. that

B. one

C. ones

D. those

答案：

(答案→)A. that

B. one

C. ones

D. those

解析：选A。句意：让Della高兴的是，她首先赢得了学生们的信任，之后又赢得了同事们的信任。空格处需用代词代替the trust，因为trust为不可数名词，故选A项。one指代单数可数名词，为泛指，其复数为ones。that可以指代上文出现的不可数名词或单数可数名词，表特指，其后常有修饰语，其复数为those。
