Word usage:

Never means "never, never", which means all negation. It generally refers to a regular state and is not used to modify one-time specific actions. Never is generally placed after the linking verb and auxiliary verb and before the substantive verb; if it modifies the infinitive or participle of the verb, it must be placed before the infinitive or participle.

never can be used at the beginning of a sentence to strengthen the tone, and the subject and predicate of subsequent sentences should be inverted. The meaning of the sentence will be different when the position of never is different.
