On these we had to say if the sentence is Prepositional phrase, Participial, Gerund phrase, Infinitive phrase, or Appositive phrase. 1. Losing weight gradually gives the body time to adjust. I can not figure out if it is an Infinitive phrase, or Participial phrase.

"Losing weight" is a gerund phrase.

"To adjust" is an infinitive.

To determine whether the phrase in question is an Infinitive or Participial phrase, we need to understand the properties and characteristics of both types.

An Infinitive phrase typically begins with the word "to" followed by a verb (e.g., to run, to eat, to study). It functions as a noun, adjective, or adverb in a sentence.

On the other hand, a Participial phrase consists of a present participle ("-ing" form of a verb) or a past participle ("-ed," "-d," "-t," "-n," or "-en" form of a verb) along with any modifiers and complements. It functions as an adjective in a sentence.

Now, let's analyze the sentence: "Losing weight gradually gives the body time to adjust."

In this sentence, "Losing weight gradually" is the phrase in question. We can identify it as a Gerund phrase. Gerunds are verb forms ending in "-ing" that function as a noun in a sentence. In this case, the phrase functions as the subject of the sentence.

To summarize, the phrase "Losing weight gradually" is a Gerund phrase.

Now, let's break down the other possibilities:

- Prepositional phrase: A prepositional phrase begins with a preposition (e.g., in, on, at, to, through) and ends with a noun or pronoun. There is no preposition in the phrase "Losing weight gradually," so it cannot be a prepositional phrase.

- Infinitive phrase: An Infinitive phrase starts with the word "to" followed by a verb. Again, "Losing weight gradually" does not fit this structure, as it lacks the "to" at the beginning. Therefore, it is not an Infinitive phrase.

- Participial phrase: As mentioned earlier, a Participial phrase consists of a participle (verb form ending in "-ing" or "-ed," etc.) with modifiers and complements. Since "Losing weight gradually" does not function as an adjective, it is not a Participial phrase.

Hence, the correct identification is Gerund phrase.
