22.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 horizon, that Halley’s comet will pass the next time it appears. (A) that Halley’s comet will pass (B) that Halley’s comet is to be passing (C) as Halley’s comet (D) as will Halley’s comet (E) as Halley’s comet will do

the key: D （1）为什么不选E?因为do多余？还是因为do 与主句的 passed 时态不同？

（2）as will Halley’s comet为什么要到装？

谢谢！
