In no other historical sighting did Halley’s Comet cause such a worldwide sensation as did its return in 1910–1911.
翻译：历史上没有哪次哈雷彗星回归造成了跟1910-1911回归的这样的世界性范围的轰动。前后有一个大的对比，前面可说的是in no other historical sighting，as后面当然要以再什么什么这个表达方式开头才能和划线外对应，只有C了！

一方面是俩时间作对比，另一方面你选ABD，那不就成了彗星和彗星的回归做对比了么，这俩不可比啊2 2 回复 2019-10-05 09:52:59

比较的内容是HC导致的sensation，比较对象是other 和 1910-1911的return0 0 回复 2019-09-23 12:35:54

1. A physical object (comet)
• An event (its return)
所以comet 和 event 不平行
in no other music festival did jimi hendrix cause such a spectacle as woodstock.
this is ambiguous. there are two possible interpretations:
(1) ...as IN woodstock (this is analogous to the intended meaning of the posted problem)比较的是音乐节和woodstock
(2) ...as DID woodstock (i.e., you're comparing the spectacle caused by jimi hendrix to the spectacle caused by woodstock itself)比较的是jimi 和Woodstock
the same two types of interpretations are possible for the posted problem.
所以这题里面，若是E选项的in 变成of，CE选项的区别只有in有无省略的问题，则选有in 的C选项；
这里such 。。as 不是举例子，而是分开用，as作为比较连词，
such a/an X as Y 这是另外一个结构——— I have never met such a hard worker as your brother.
但是在这题中E选项：such a worldwide sensation as its return—是有问题的，因为语义不是这样的，所以这也是为什么in不能省略的原因
原句In no other historical sighting did Halley's comet cause such a worldwide sensation as (Halley’s comet caused / did cause a worldwide sensation) in its return of 1910-1911.
Halley’s comet caused such a worldwide sensation in no other historical sighting as in its return of 1910-1911.
5. the "of" is used to avoid the construction "X in Y in Z".
当在选项中遇到有多个一样的介词或连词时，一般正确选项要改变其中一个，避免这种结构的出现they will go out of their way to avoid "X of Y of Z", "X that Y that Z", "X to Y to Z", etc.0 0 回复 2019-03-06 20:02:40
OG有时候是很精彩的The single subject of this sentence is Haileys Comet, and its single verb phrase is did cause. The comparison presented by the sentence is between adverbial phrases describing times when the comet was seen. Grammatically, the items being compared are parallel prepositional phrases beginning with the preposition in: in no other sighting and in its return in 1910-1911. This is the clearest, most economical way of presenting the information. The options that introduce a second verb (did or had) violate the parallelism and introduce a comparison between the comet itself (subject of the verb did cause) and the comet’s return (subject of the verb did or had).0 0 回复 2018-12-14 18:07:15

Quote: (A) did its return in 1910-1911 There are two ways to think about why (A) is wrong. First, we could think about what, exactly, is being compared: “in no other historical sighting did Halley’s comet cause such a worldwide sensation as ________.” The heart of the question is that we’re trying to compare what happened in other historical sightings to what happened in 1910-11. So to keep the comparison even, it makes more sense to fill in the blank above with “in its return of 1910-11.” And that’s answer choice (C). We’ll get to that one shortly. The second tool that’s helpful here: the helping verb “did” can play a variety of roles in English, but in this case, it’s basically trying to replace another verb. Think of it as analogous to a pronoun, except that it refers to a verb instead of a noun. And that means that we can replace “did” with the verb phrase that it refers back to: “cause” (or "caused", if we take some minor liberties with the verb tense). So we have: “In no other historical sighting did Halley’s comet cause such a worldwide sensation as caused its return in 1910-11.” That’s pretty ridiculously ugly. (A) is out, whichever way you prefer to think about it. Quote: (B) had its 1910-1911 return I can’t make any sense of why we would use “had” here. I don’t really even understand what it means when it’s used by itself: I guess the sentence is trying to say “… as its 1910-11 return had caused”? Except that there’s no good reason to use past perfect here, and there’s no good reason to just hallucinate the word “caused” in that situation. Plus… well, the heart of the comparison needs to revolve around the phrase “in no other historical sighting”, as discussed under answer choice (A). So (B) is gone. Quote: (C) in its return of 1910-1911 Bingo! I know that I’m repeating what I wrote for answer choice (A), but here’s the beginning of the sentence again: “in no other historical sighting did Halley’s comet cause such a worldwide sensation as ________.” The heart of the question is that we’re trying to compare what happened in other historical sightings to what happened in 1910-11. So to keep the comparison even, it makes more sense to fill in the blank above with “in its return of 1910-11.” And that’s exactly what (C) does. Let’s keep it. Quote: (D) its return of 1910-1911 did You can use the same argument for (D) as we did for (A): if “did” replaces “caused”, this makes no real sense. “In no other historical sighting did Halley’s comet cause such a worldwide sensation as its return of 1910-11 caused.” That’s not the very worst thing, but it certainly isn’t great – and it’s definitely not capturing the essence of the comparison as sharply as (C). So we can ditch (D). Quote: (E) its return in 1910-1911 (E) isn’t completely horrible, and I’d be fine with this in real life. But again, (C) does a much, much better job of capturing the essence of the comparison. So (C) is our answer.0 0 回复 2018-11-06 21:04:09

如果补全省略内容，改为正常语序后整句话为“In no other historical sighting Halley's Comet caused such a worldwide sensation as (Halley's Comet caused) in its return of 1910-1911”括号中的主谓结构是比较结构中的第二项，由于和第一项内容基本相同，所以被省略了。 所以本题实际上比较的是“哈雷彗星”在“other historical sighting(其他历史环境下)”和“哈雷彗星”在“它1910-1911的回归地球”的历史环境下，其造成的“轰动”的比较，“In no other historical sighting”和“in its return of 1910-1911”分别参与比较的两个主谓结构的时间状语。 其他选项中“its return in 1910-1911”要么在和“Halley's Comet”直接比较(排除(A)、(B)、(D))，要么不知和谁在比(排除(E))，没能建立准确合理的比较关系。0 0 回复 2018-08-10 15:42:51
