Although she had signed a pledge of abstinence while being an adolescent, Frances Willard was 35 years old before she chose to become a temperance activist. (A) while being an adolescent (B) while in adolescence (C) at the time of her being adolescent (D) as being in adolescence (E) as an adolescent 答案是D,我明白,但不明白B错在哪里 OG上的解释是:while in adolescence is not the correct idiom for this sentence. 那请问while在这里为何不能这么用呢? |
