我可不可以把while看做连词，即B中while in adolescence是一个从句的省略形式，即可还原为while F had been in adolescence.这样while表示两个动作同时发生，主句是过去完成时，从句也是。那么B也对啊？！望指教，谢谢。

我觉得这里要补出的应该是was, 而不是had been. 过去完成时没道理。而且这种句式在OG31里被否掉了。
31. Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.
(A) Unlike computer skills or other technical skills, there is a disinclination on the part of many people to recognize the degree to which their analytical skills are weak.
(B) Unlike computer skills or other technical skills, which they admit they lack, many people are disinclined to recognize that their analytical skills are weak.
(C) Unlike computer skills or other technical skills, analytical skills bring out a disinclination in many people to recognize that they are weak to a degree.
(D) Many people, willing to admit that they lack computer skills or other technical skills, are disinclined to recognize that their analytical skills are weak.（D）
(E) Many people have a disinclination to recognize the weakness of their analytical skills while willing to admit their lack of computer skills or other technical skills.
Choice D is best. Choice A illogically compares skills to a disinclination; choice B compares skills to many people. Choice C makes the comparison logical by casting analytical skills as the subject of the sentence, but it is awkward and unidiomatic to say skills bring out a disinclination. Also in C, the referent of they is unclear, and weak to a degree changes the meaning of the original statement. In E, have a disinclination... while willing is grammatically incomplete, and admit their lack should be admit to their lack. By making people the subject of the sentence, D best expresses the intended contrast, which pertains not so much to skills as to people’s willingness to recognize different areas of weakness.
可是为什么In E, have a disinclination... while willing is grammatically incomplete
while willing 为什么语法上不完全啊？

一般来说，有being的选项都是不正确的，gmat不喜欢这个词啊！while在gmat中只作连词，后跟句子。有while +v ing的形式。只有e最好。as作介词＋n.
不要再用这个来判断！
willing是形容词，固定搭配是be willing to，所以不完整！
while willing 为什么语法上不完全啊？
http://forum.chasedream.com/dispbbs.asp?boardID=23&ID=26957
请参考8楼tianwan的详细解释。
但我在longman中发现一个句子：She met Andy while working on a production of Carmen.
这里的while working可以被还原成while she was working on...， 如果按照tianwan的解释，这个句子while前后没有使用同一个动词，是不是就成了病句？
还有如果上面的例句是正确的，那么og69的 while being 也应该是正确的喽？
把og31和og69混在一起讲是危险的，因为
1. OG对其解释不一样：
og31: while willing to admit... => "grammatically imcomplete"，就是说认为其语法上不完整
og69. while being an adolescent... => "unidiomatic"，就是认为"gmatly"不地道，虽然语法上可能对
2. 两个while用法不同，og31 while作“虽然”用表让步，而og69作“当...时候.”用。
3. 两个while接的东西不一样：og31 接形容词，og69接分词。
所以，while being 语法上对的，但是，GMAT就不喜欢while being，说穿了压根就不喜欢being，就象女生不喜欢老鼠一样。连being都不喜欢，而且根正苗红的as可完全替换while being，while being还能对吗？Longman的句子在GMAT里是100％对的，因为working不是老鼠(being)，as也不能替代while working，而且又简洁。其次，我见过while表“在...时候”省略主语和系表结构的be，但未见有表让步时省的。个人判断，如果og31不是ETS笔误的话，可以认为while表让步直接加形容词就是错。如果有人在GMAT里见到过，请指正，谢谢。
以下是中国教育资源网上搜到的while用法，供参考：（http://edu.jtjy.com)
连词while大致有以下四种用法:
1.引导时间状语从句,意为"当……的时候;和……同时",此时的主从句谓语动作同时发生,从句谓语通常是延续性动词。如:
Mary watched TV while she ate her supper.玛丽边吃饭边看电视。
While she was listening to the radio, she fell asleep.她听着收音机睡着了。
while引导从句时,如主从句的主语一致,且从句谓语又含有be,则从句主语和be可省略。while后可直接跟现在分词、名词、形容词或介词短语。如:
We are teachers while (we are) serving as students.我们边当老师边当学生。
While (he was) yet a youth, he gained many prizes.他年轻时就曾多次获奖。
He caught a cold while(he was) on vacation.他度假时患了感冒。
2.表示对比或转折,意为"而;然而"。此时,while一般位于句中。如:
Some people waste food while others haven't enough.有些人浪费粮食,然而有些人却吃不饱。
You like sports, while I prefer music.你喜欢体育,而我更喜欢音乐。
3.表示让步,通常位于句首,意为"尽管;虽然"。如:
While I agree with your reasons, I can't allow it.尽管我同意你的理由,但我不能允许这样做。
While he loves his students, he is very strict with them.虽然他爱他的学生,可是他对学生们很严格。
While (he was) respected, he is not liked.他虽受人尊敬,但并不被人喜欢。
4.表示条件,意为"只要",其意思和用法相当于as long as。while可位于句首,也可位于句中。如:
You don't have to worry while we are here.只要我们在,你就别着急。
There will be life while there is water and air.只要有空气和水,就有生命。
While there is life, there is hope.留得生命在,不怕没希望。
5.意为"同时;也"。如:
While the book is welcomed by schol-
ars, it will make an immediate appeal to the general readers.这本书受到学者的欢迎,同时也会引起一般读者的兴趣。
6.意为"趁着"。如:
Make hay while the sun shines.晒草要趁阳光好。(谚)
Strike while the iron is hot.趁热打铁。(谚)
While the roses are yet in bloom, will you come with me to see them?趁着玫瑰花还开着,你和我一道去看看好吗？
谢谢anyname的解释，精辟，幽默，全面
while 引导让步壮语从句 + 系表结构，主语和系动词不可省
可以认为while表让步直接加形容词就是错。如果有人在GMAT里见到过，请指正，谢谢。
3.表示让步,通常位于句首,意为"尽管;虽然"。如:
While I agree with your reasons, I can't allow it.尽管我同意你的理由,但我不能允许这样做。
While he loves his students, he is very strict with them.虽然他爱他的学生,可是他对学生们很严格。
While (he was) respected, he is not liked.他虽受人尊敬,但并不被人喜欢。
To Anyname: 那么这个例子就不能省he was ? 如你上头所说,对吧?

While (he was) respected, he is not liked.他虽受人尊敬,但并不被人喜欢。
To Anyname: 那么这个例子就不能省he was ? 如你上头所说,对吧?
如果上述while理论成立的话，这里应该不能省he was 。另外，如果GMAT真出这么一道题给he was repected划线的话，我会选择保留was的选项，因为其时态和主句不同，不宜省略。当然，GMAT口号是：”没有不好，只有最好“，一切还得相机行事。
我查了大全，while使用频率不低，但正确答案和句子中个人只见有“while+v-ing”和while引导从句两种情况。不过（！）有一个例外，就是以下句子：
In E, the infinitives to decrease and to improve, while parallel, are less idiomatic than the prepositional phrase of decreasing... and improving in modifying the noun aim.
这句话出现在og212的解释中！而且就是while表让步直接接形容词 ！不同的是，while前有逗号。如果og解释也是按GMAT语法标准写成的话，我们可能只好将上述理论修改成，while表让步可直接接形容词，但从句前或后要逗号隔开。看来我们还得再继续探讨探讨。
最后，非常感谢billion同学热情鼓励。
while表示当....时的时候是不可以表时间点的。而这里的动作at a time是表瞬时的。所以while肯定错。
being，还有延续性or ongoing的误导吧？
请指教。

do sth. while doing sth. 逻辑主语的判断。while being是错误用法
while doing 是状语从句省略的一种形式：就近修饰前面的动词，其逻辑主语等于前面动词的逻辑主语。例句：
In the last few years, the number of convicted criminals given community service sentences allowing them to remain unconfined while performing specific jobs that benefit the public has risen dramatically.
*当状语从句的省略形式在句首时，其逻辑主语等于主句主语，但如果在句尾或者句中，其逻辑主语优先等于它所修饰的动词的逻辑主语。
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
请教，为什么不是(B) while （she was) in adolescence，因为主句是Frances Willard was 35 years old
真抱歉上面那条发错页了。不好意思！！
是be willing to do sth
终于找到了一个能说服自己的说法，
首先，OG 69中，while表示当什么……的时候，表示两个动作同时发生，A和B就不对了。属于语法正确，但不符合习惯。
其次，OG 31中，while willing to，这个while+形容词的省略结构，GMAT认为是语法错误，OG-11解释到，Have a disinclination is wordy (the verb disinclined is preferred) and, when followed by while willing, creates an incomplete construction。应该补充一个逗号，原因在于，while引导的从句做状语，必须加逗号。
Incorrect: I couldn't pass the driving test even thoughI studied hard.
Correct: I couldn't pass the driving test, even though I studied hard.
? 状语从句放于句尾时，如果对整个句子来讲是必须的,则不要用逗号分开，反之可以用逗号分开，但在although, though, even though, no matterwhat/how/when,since,whereas, while 所引导的状语从句前一定要用逗号分开。
这个例子就是如此，这里while+形容词，省略了主语+be，完全没错！另外我查阅了GMAT 阅读和语法的大量实例，while 做状语的时候，都是有逗号的！
这么好的帖子讨论，给个精华吧！

感觉同时发生逻辑上也说的通——当她在青春期的时候她签署了。。。in adolescence/ during adolescence / as an adolescent是意义不同么？？
我怎么觉得说来说去都是一个意思呢：在12-18岁这个阶段
我想楼上说的比较明确，while在这里是多余的，可以直接用介宾短语表示在。。。期间， 如果改成while she was in adolescence呢？是正确的么？如果去掉while, 直接用during adolescence呢？
