大全94：while

centennial

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

Choices A, B, and D are unidiomatic. Choice C is awkward and wordy; furthermore, the phrase at the time of her being adolescent suggests that Willard’s adolescence lasted only for a brief, finite moment rather than for an extended period of time. Choice E, idiomatic and precise, is the best answer.

这道题og给的解释过于简单了。我想问的是，像A那样用while doing……表达一个时间状语对不对？

B,仅供参考．

状语从句的省略，只能是while+形容词/分词．while+名词/介词词组错．

chouliulu

那么b为何不正确呢？

holddreams

while + ing结构在表达状语从句时习惯上大都表示动作性状态的伴随，比如：while working/sitting等等，而A中的while being的表达不太复合习惯，所以用as更好。
