Which structure should the sentence in a piece of formal writing have

A sentence in a piece of formal writing should generally follow a clear and logical structure. This structure typically includes:

1. An introductory phrase or clause that introduces the main idea or topic of the sentence.
2. A subject that clearly identifies who or what the sentence is about.
3. A verb that shows the action or state of being of the subject.
4. Additional information or modifiers that provide more details or clarify the subject or the action.
5. A clear and coherent conclusion or ending to the sentence.

Remember to use proper punctuation and grammar rules to ensure clarity and accuracy in your writing.
