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, the next time it appears. ------------ A. that Halley's comet will pass D. as will Halley's comet E. as Halley's comet will do ------------- 答案为D。请问： 1.E 为什么不可以？和D不是等效的吗？ ------ 2.另： i) A letter by Mark Twain, written in the same year as XXX was published, reveals that ..... ii)A letter by Mark Twain, written in the same year that XXX was published, reveals that ..... LZM上的解释为：“上面这两句等效，as和that可以互换，均指代时间状语in the same year。” 那么此题的A答案为什么不正确？ --------- 3.A改为“as Halley's comet will pass”之后，是否正确？ -------------------- 谢谢！
