There are seven kinds of English sentence components: subject, predicate, object, attribute, adverbial, predicate and object complement. Details are as follows:

1, subject: the subject of the sentence, the object of the whole sentence. The answer is "who" or "what". Generally, it is taken from nouns, pronouns, infinitives, gerunds or clauses and is located at the beginning of a sentence.

The boy needs to open it

Smoking is bad for you.

2. Predicate: Explain the action or state of the subject. Answer "Do (what)". It is acted as a verb or a copula plus a predication, usually after the subject.

For example, the training class at 6 o'clock.

She is reading a book.

3.Object: the object representing the operation. The answer is "what". Generally borne by nouns or pronouns, often placed after predicates.

He is in the game.

Helicopter game computer.

note:

(1) Some transitive verbs have two objects, one refers to the object (direct object) and the other refers to the person (indirect object).

Indirect objects are usually placed before direct objects.

He wrote a letter.

(2) Sometimes the preposition to or for can be added before the indirect object to form a phrase, and placed after the direct object to emphasize the indirect object.

He wrote. He wrote me a letter.

4. Predicate: used to express the characteristics, status and identity of the subject. The answer is "what" or "how". Generally speaking, it is acted by a noun or adjective, and placed after a copula or a be verb.

For example, Heisastudent.Wearetired.

Note: Besides the be verb, there are some verbs that can also be used as verbs.

(1) Verbs expressing feelings: feeling, smell, taste, sound, appearance, obvious, seemingly, etc.

(2) Verbs expressing change: change, gain, length, turn, go, etc.

(3) Verbs indicating continuation: keep, keep, hold, stay, rest, etc.

Attribute: a word, phrase or sentence that modifies or restricts a noun or pronoun.

Such as: Theblackbikeismine (adjective)

Blue is Jim. (prepositional phrase)

I didn't today. (infinitive)

note:

(1) When the attribute modifies indefinite pronouns, such as nothing, any, everything, something, etc. This attribute should be placed after it as postattribute. Like itellhimstogether

(2) When an infinitive, phrase or clause is used as an attribute, it is also placed after the modified noun.

For example, theboyswoareinthheroumare lays games.

6. Adverbial: used to modify verbs, adjectives, adverbs and the whole sentence, usually adjectives, pronouns, numerals and so on.

(1) When modifying an adjective or adverb, it usually comes before the modified word;

For example, I'm sorry

(2) Adverbials indicating time, place and purpose are generally located at both ends of a sentence, with emphasis on the beginning of the sentence.

Such as: inordertocheerhimup, itoldhimthetruth.

They are writing in the classroom.

(3) Adverbials indicating uncertain time (such as oft) or degree (such as almost) are usually located after be verbs, auxiliary verbs and modal verbs, and before verbs.

We often help him.

He is always late.

7. Supplement: A supplementary explanation of what or how an object is. Through nouns/adjectives/objects/participles/infinitives, etc. Often located after the object.
