English problem!

It is relatively easy to separate the components of a sentence from the predicate verb. The part in front of the predicate verb is the subject, followed by the object. It is an adverbial modifier of predicate verbs and an attribute modifier of subject and object. If the predicate is a copula, the part behind the copula is the predicate. For example:

I am a teacher. I is the subject, am is the predicate and the teacher is the predicate.

He likes playing football very much. He is the subject, like is the predicate, playing football is the object, very adverbial.

Adverbials can be flexibly placed at the beginning, middle or end of a sentence. For example:

She was playing the piano when I went to see her.

He likes playing football very much. (End of sentence)

I have never been there before.

The predicate comes after the copula. For example:

I am a teacher. Among them, the teacher is a predicative.

My opinion is that you should go there alone. Among them, the clause guided by that is also a predicative.

Preposition is to express the relationship between its object and other words in the sentence.

A preposition and its object together form an object-object phrase, which can be used as a noun, adjective or adverb. Commonly used prepositions are:

In, in, in, from, to, up, down, above, below, in, in, beyond, etc.

4. Transitive verbs can follow the object directly, but intransitive verbs can't. You need to add a corresponding preposition before you can add an object.

Transitive verbs usually emphasize action, while intransitive verbs usually emphasize state.

For example:

We raised the flag.

We raised the red flag. (among them, raise is a transitive verb)

The flag is being raised.

The red flag is rising. (among them, rise is an intransitive verb.
