就比如那个with用逗号隔开的问题吧。难道你想把with两边用几个逗号有多少种可能都背下来吗?逗号最大的作用是为了划分句子结构避免歧义,其次是调节行文节奏性。一些文学作品里,逗号出现的位置经常很诡异,但都不难理解啊,根本没必要这样刨根问底。
A. 独立主格:He went out of the room,she saying nothing.
This sentence is really, really 1. Tensed Verb Requirement for Independent Sentence/Clause
「she saying nothing」 is neither an independent sentence nor independent clause. An independent sentence/clause needs a tensed verb, and 「saying」 is not a tenses verb.You should say: 「She said nothing」.
2. Comma Splice
Joining 2 independent sentences/clauses with a comma is called 「comma splice」 and it』s a very bad grammatical mistake.You can join 2 independent sentences/clauses with period, semicolon or conjunction, like these:
a. He went out of the room. She said nothing. (separated by period)
b. He went out of the room; she said nothing. (separated by semicolon)
c. He went out of the room and she said nothing. (jointed by conjunction 「and」)
B. a. Both of them went out together and she said nothing.
b. He went out, and she said nothing.
Secondly, if I understand you correctly, you indicate there is an Object in this sentence. There is no Object in this sentence. The Verb 「went」 is an Intransitive Verb and it cannot have an Object or Object Complement.
The phrases 「of the room」 and 「with her saying nothing」 are Prepositional Adverbial Phrases modifying the Phrasal Verb 「go out」.So, I am lost at what your question is here.
