The first question uses analytic hierarchy process to analyze the following syntactic structure.

The first sentence is a prepositional phrase with object-object structure, which is generally used as an adverbial in the sentence.

The second sentence uses a phrase with predicate-object structure, which is usually used as the subject or object in the sentence.

The third sentence uses a phrase with subject-predicate-object structure, which is usually used as a preposition.

In the fourth sentence, the predicate-object structure is used as the attribute of "person" first, and then the subject-predicate structure is formed as a whole, which can be used as a sentence independently or as a component in a sentence.
