白勇语法全解，比较结构的第51题

小小照妖镜

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 about 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

答案是 D 选项

解释说：
E 选项  主句谓语动词短语使用“助动词（如 have，has， had，will）或者情态动词（can，could，may，should）+ verb ” 形式时，比较从句往往省略 verb， 保留助动词或者情态动词。 as Halley's comet will do, do多余，必须省略。

可是句中没有这些助动词或者情态动词之类的啊，难道指的是passed，为什么？

就是不知道它说的助动词或者情态动词指的主句句子里具体哪个词

找了Manhattan上NN的解释

Neeshpal, you did well to identify the same as idiom and eliminate A and B. Next, answer choice C changes the original intent of the sentence, since Crommelin did not pass the Earth where Halley's comet is currently located; instead, Crommelin passed the Earth in about the same position as Halley's comet will pass the Earth. The problem with answer choice E is that, by including the helping verb will, the primary verb pass is already inplied. Thus, answer choice E actually "reads" the comet Crommelin passed the Earth at about the same distance and in about the same position as Halley's comet will do pass the next time it appears. Thus, the verb do is both unnecessary and is not parallel to the verb pass.

The correct answer is D.

谢谢lz问了这个问题，以前看白勇的时候都没有认真想过呢
