关于OG10-69 的疑问！~！

hilasa

69. 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


正确答案选E

想问下B为什么不对 OG说Choices A, B, and D are unidiomatic.

但我认为B为状语从句省略形式while (she was) in adolescence 感觉对的

希望NN们指教！

b对但是没有e简洁

B不对，不能这样省略，when ,while等连词的后面省略主谓后剩下的必须是分词短语，不能是介词短语和名词短语，否则不能省略。
