1. Subject + Verb: This is the most basic sentence structure in English, where the subject performs an action or state of being.
Example: She sings beautifully.
2. Subject + Verb + Object: In this sentence structure, the subject performs an action on an object.
Example: He ate a sandwich for lunch.
3. Subject + Verb + Indirect Object + Direct Object: This sentence structure involves the subject performing an action on a direct object and giving something to an indirect object.
Example: She gave her friend a birthday present.
4. Subject + Linking Verb + Predicate Adjective/Noun: In this sentence structure, the linking verb connects the subject to a predicate adjective or noun that describes or renames it.
Example: The flowers are beautiful.
5. There is/are/was/were (Existential Sentence): This type of sentence emphasizes existence and location of people, things or ideas in relation to each other using "there" as a dummy subject followed by a form of "to be".
Example: There are many books on the shelf.
