0Hi, I would like to ask how we can determine the omitted subject of a participle clause(since the omitted subject of a participle clause can be the subject of the main clause, the entire main clause, part of the main clause, or the object of the main clause, I just find it very hard to determine the omitted subject of a partiple clause ), and when we turn a participle clause into a complete sentence, what tense should be given to the new sentence? I attempt to turn the following participle clauses into complete sentences, please correct them if there are any mistakes. Thank you very much.02br
