178. In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.

(A) sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have

(B) sentences, performing specific jobs that benefit the public while being allowed to remain unconfined, have

(C) sentences, performing specific jobs beneficial to the public while they are allowed to remain unconfined, have

(D) sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has（E）

(E) sentences allowing them to remain unconfined while performing specific jobs that benefit the public has

首先，E原句the number of convicted criminals given community service sentences allowing them to remain unconfined while performing ... 的前半部分主语是the number，其后跟了of, given, allowing都是修饰成分，而while显然不是修饰名词的，而是做状语修饰句子的，所以从结构上while不可能修饰任何主语the number，而只可能做to remain这个结构的状语，而对象是针对them这个在子句中的主语；

233. Recently implemented “shift-work equations” based on studies of the human sleep cycle have reduced sickness, sleeping on the job, fatigue among shift workers, and have raised production efficiency in various industries.

(A) fatigue among shift workers, and have raised

(B) fatigue among shift workers, and raised

(C) and fatigue among shift workers while raising

(D) lowered fatigue among shift workers, and raised（C）

(E) and fatigue among shift workers was lowered while raising

"WHILE DOING" 在这二题中, "doing"的主语在233是主句主语,在178却是最近的代词"them"不是主句主语, 请问各位ggjj,这种结构"doing"的主语有规律可寻吗?

先谢啦.
