问题补充:
(·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。
