就比如那個with用逗號隔開的問題吧。難道你想把with兩邊用幾個逗號有多少種可能都背下來嗎?逗號最大的作用是為了劃分句子結構避免歧義,其次是調節行文節奏性。一些文學作品裡,逗號出現的位置經常很詭異,但都不難理解啊,根本沒必要這樣刨根問底。
A. 獨立主格: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.
