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

答案是E 选出答案没有问题 但是对于选线D 我想说是不是转移了avoid后面这部分内容的重心？本身这个while 在这里的用法有什么问题吗？我看到解析里的一条：1、 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 表示非常不能理解~~~~ 有NN讲解一下吗
