as,than后是否倒装

新东方教材29页12题，In its most recent approach, the comet Crommelin passed the Earth at about the same distance and in about the same position, some 25 degrees above the horizen, that Halley's comet will pass the next time it appears.

a.that Halley's comet will pass

c.as Halley's comet

d.as will Halley's comet

e.as Halley's comet will do

答案选D,我不确定E错的原因是不是will 后面补充了do?如果没有的话不用倒装对不对呢？

另外，记得有些题是考than后面跟什么的。同样的问题，than后面是否倒装？怎样省略、补充句子？

请NN解惑~~
