Question

1:___,once a god had given a gift ,it could not be taken away
A:Though powerful Zeus
B：Powerful as Zeus was
C：As Zeus was powerful
D：Powerful was Zeus
意思?句子构造?我觉得句子翻不通

Answer 1

答：原题句摘自：Prometheus knew that he would not have much time before Zeus discovered that he had been disobedient.But he also knew that,powerful as Zeus was,once a god had given a gift it could not be taken away.
是that引导的宾语从句部分.
这个句子是一个复合句.Powerful as Zeus was是让步状语从句,相当于Though Zeus was powerful,
连词AS的用法很多,它也可以引导让步状语从句,但必须将表语（形容词）或状语（副词）提到句首,形成所谓的倒装（但并不是真正的主谓倒装,其实主语还是在谓语的前面）.
而后面的主句其实不是一个简单句,而是一个复合句：
once a god had given a gift,it could not be taken away.
其中once a god had give a gift,是时间（+条件）状语从句,表示“一旦.”
这里的a god不是指“上帝”,那是要大写的,是指众神之一.give a gift指的是给出了gift,这里指普罗米修斯给人类的gift,只要给了之后,就收不回来了,即使强大如宙斯,也收不回来（所以人类才有了火）.
参见：百度文库》教育专区》外语学习》英语学习》21.Prometheus
本句是一个嵌套句.
让步状语从句+大主句
大主句=时间（条件）状语从句+小主句.
