杨鹏难句 - 2nd sentence

"A desire to throw over reality a light  that never was might give away abruptly to the desire on the part of what we might consider a novelist-scientist to record exactly and concretely the structure and texture of a flower."

The original sentance of the never was might give away, according to Yangpeng, should be:  'might never be given away'. My question is why we need to change 'be' into 'was'?  since we need to only emphasis on NEVER, we may as well use 'never be might give away'. I think this is more appropriate change, rather than 'never was might give away'.

Any opinion?

never was might give away to实际上应该是was never (might)given away to,因为有了might,所以given 变give,这是杨鹏的解释,虽然我也不是很明白～～～

ps:你用的也是gre难句，请问大家用的都是gre难句吗？我是在下载区down的，但其他几位提问题的好象用的和我们不是一个版本，疑惑中～～～是不是还有个gmat难句？哪位好心人解答一下～～～
