117. Performing a risky maneuver that required precision flying, not only did space shuttle astronauts retrieve an orbiting satellite, it was done simultaneously while avoiding being rear-ended by a passing ultraviolet telescope.
A. not only did space shuttle astronauts retrieve an orbiting satellite, it was done simultaneously while avoiding
B. not only was an orbiting satellite retrieved by space shuttle astronauts, but they also simultaneously avoided
C. an orbiting satellite was retrieved by space shuttle astronauts who also avoided simultaneously
D. space shuttle astronauts retrieved an orbiting satellite, simultaneously while avoiding
E. space shuttle astronauts retrieved an orbiting satellite and simultaneously avoided
A: not only … it … 不对称
B: they 和satellite不一致；performing修饰satellite错
C: 同上
D: while不对，应该是并列关系不是转折
E: correct
注意：
1、 not only did A/As do, but it/they also do
2、 while表转折让步时才能省略主语和系动词，表示当。。。时不能省略
以上是F大牛对此题的解释
对Ｄ我还是很不理解:我认为while表时间也是可以省略的，就像when一样.那么,D还有什么不对呢?
请NN帮忙解答
谢谢!
等NN
自己顶..
先不看D为什么“错”
你自己觉得DE两个句子哪个更好？为什么更好？
E确实比较工整..
但是看到 ,doing 就狂想选...
那D到底哪里错了呢...
不过我看到while也心里一紧张的。
By contrast, the individualist feminist tradition emphasizes individual human rights and celebrates women’s quest for personal autonomy, while downplaying the importance of gender roles and minimizing discussion of childbearing and its attendant (accompanying or following as a consequence or result “problems attendant upon pollution”)
responsibilities.
找了一个这个句子。不过也说不上来为什么D就是不对，看着E比D好。
等着NN来讲讲WHILE吧。
不是NN，说说我的理解，这里的retrieve和avoid从逻辑上讲是并列的，D的话把avoid作为伴随，所以错。其次，simultaneously while ...这里的simulataneously应该修饰avoid，可是D里面却awkardedly修饰了while从句。
open to discussion
asupls说的有道理，D里面的simultaneously位置是不太好，并且，simultaneously=things that are simultaneous happen at exactly the same time ,充分说明了文中要表达是两个同时发生的动作。
如果有逗号，通常是while引导的是时间状语从句，表示持续的动作，说在avoid这个动作的持续状态下，astronauts在retrieved。这个和要表达的两个动作同时发生是不一样的。
如果此句中while表示转折，那通常不逗号，直接是：space shuttle astronauts retrieved an orbiting satellite while avoiding being rear-ended by a passing ultraviolet telescope.但是文中没有转折的意思。
open to discussion.

看一下，有没有点帮助。
原来有讨论过了啊~看到置顶里没有贴就直接发新的了呢
闹闹有关avoid无法持续这个说法真是太绝了,佩服佩服
不过我又想了想,觉得while和simultaneously似乎还是有些重复的.因为while这里是表示当...时候
while at the same time是不重复的 是因为这个while是当转折讲的
不知道我这个想法对不
请指教^^

我后来又改了说法，因为在NYTIMES上读到了用avoiding句子，又觉得自己的想法不正确。
个人认为你对while的理解是对的。
