I do not understand the difference between "first aired" and "aired first on". Could NN explain to me? I guess the first one emphasizes the word "aired"; The second one emphasizes " on evening radio". I think both of these should be ok. In the test, which one should we pick?

170. Although early soap operas were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's when the evening schedule became crowded with comedians and variety shows.

(A)  were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's

(B)   were first aired on evening radio in the 1920's, they were moved to the daytime hours in the 1930's

(E)   aired on evening radio first in the 1920's, they were moved to the 1930's in the daytime hours

要放到全句的环境中看

A  soap operas were first aired on evening radio in the 1920's  是说最先是播出在晚上的这个时段

E soap operas aired on evening radio fist in the 1920's 强调的是， 在晚上播出（这种状况），最早出现在1920年

170. Although early soap operas were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's when the evening schedule became crowded with comedians and variety shows.

(A)  were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's

(B)   were first aired on evening radio in the 1920's, they were moved to the daytime hours in the 1930's

(C)  were aired first on evening radio in the 1920's, moving to the daytime hours in the 1930's

(D)  were aired first in the evening on 1920's radio, they moved to the daytime hours of the 1930's

(E)   aired on evening radio first in the 1920's, they were moved to the 1930's in the daytime hours

Choice B is the best answer. It maintains the passive voice and the past tense (were ... aired) established in the intro­ductory clause. Choice D breaks this parallelism by shifting from passive to active voice (moved). Choice A also uses the active voice and inappropriately shifts to the past perfect tense (had moved); the past perfect should be used to indicate action completed before, not after, the action of were aired. In C, moving introduces a dangling participial phrase in place of an independent clause, thus producing a fragment. E drops were before aired and finishes the sentence with two prepositional phrases that distort the meaning.

紫色的部分不是很能理解, 为什么就说是形成了一个Fragment? 请教了.

因为句子由Although引导，后面应该还有一个句子与这个句子构成转折，否则这个句子就是不完整的啦

(C)  were aired first on evening radio in the 1920's, moving to the daytime hours in the 1930's

moving to the daytime hours in the 1930's 无法与前句构成完整的转折结构，所以ETS 就说C, moving introduces a dangling participial phrase in place of an independent clause, thus producing a fragment.
