A participial turn is a special syntactic construction.
It must be able to find, because it depends on the correct definition of the syntactic role of words, and therefore, and the formulation of punctuation.
Before looking in the text, the adverbial Turnovers, Learn to find gerundances. Different sources give different definitions to this category of words. Someone views it as a special form of the verb, and someone - as an independent part of speech. The first interpretation is more characteristic for scientific language works, and the second is considered school. At school, children traditionally study verbal participles as a special part of speech. The participle has the value of an additional action under the main action. The semantics of gerunds implies a combination of signs of action and mode of action. For example, "reading". This question can be asked the question "What is doing?", Which, however, from the language point of view will not be entirely correct, but you can ask the question "How?". These questions illustrate the dual nature of the verbal participle. The gerunds can be perfect or imperfect. The former speak about the action taking place at the moment or about that which is to be accomplished in the future. The second - about the actions that occurred in the past (compare: "looking" and "glancing").
Now go to the search for gypsy participles. Speech participles are verbal participles with dependent words. The main mistake in the search is usually made in the search for dependent words - for the gerundive turnover, words belonging to another member of the sentence are accepted. In order not to make mistakes, carefully watch the word from which the question is asked. For an example, consider the sentence: The girl ran along the cobblestone road, singing a song with joy. Find the gerund. In this case, this word is "singing". Now we need to find dependent words. Ask questions: "Singing ... what?" Song. " "Singing ... how?" It's joyful. " Hence, the words "song" and "joyfully" will be dependent on the gerund, and, therefore, all together they form a participial turn. The participial turn in the sentence is an isolated circumstance and always stands out with commas on both sides.
