Почему Он пересказывал текст, (не) смотря в учебник ? Как объяснить правило написания смотря в данных предложениях?

Пять дней ноября. So, I can see that you have provided three examples of using the expression "не смотря" in different contexts. You correctly pointed out that the way it is written can vary depending on its usage. Let"s analyze each example in more detail to understand why "не смотря" is written differently in each case.

1. "Не смотря на усталость, он продолжал идти вперед" - In this sentence, "не смотря на" is used as a prepositional phrase to express a condition contrary to what is expected. It is important to note that in this case, "смотря" is not a verb but a preposition that is part of the phrase. Therefore, "не смотря на" is written together as one word.

2. "Не смотря на то, что у меня болела голова, я радовался чудесному утру" - In this sentence, "не смотря на то что" is used as a conjunction to introduce a subordinate clause. It indicates a contrast between the condition expressed in the subordinate clause and the main clause. Similar to the previous example, "смотря" is not a verb but part of the conjunction. Therefore, "не смотря на то что" is also written together as one word.

3. "Прозерпина складывала карты в стопочку, игнорируя их. Сквозь стеклянную крышу вливаются потоки света, свет проникает через покрытие столов. Прозерпина кивает, но продолжает собирать пасьянс, (не) смотря в учебник." - In this sentence, "не смотря" is used as a participle in the construction "не смотря в учебник." It modifies the verb "собирать" and expresses the manner in which the action is performed. Here, "смотря" is a verb in its infinitive form. Since it is a separate verb, it is written separately from the negation particle "не."

In conclusion, the expression "не смотря" can be written differently depending on its usage. When it is used as a prepositional phrase or as a conjunction, it is written together as "не смотря на" or "не смотря на то что." However, when it is used as a participle modifying a verb, "смотря" is written separately from the negation particle "не." It is important to understand the context and the role of "смотря" in the sentence to determine its correct writing.
