To ensure sentence variety in writing, it's important to use a mix of sentence structures (simple, compound, complex), vary sentence beginnings with different types of words (subjects, adverbs, prepositional phrases, interjections, adjectives), and incorporate different sentence types (declarative, interrogative, imperative, exclamatory) based on the context and purpose of the writing. Regularly reviewing and editing the writing, or having someone else review it, can also help identify and address any patterns or lack of variety in sentence structure.

I believe that people fear the idea of completing their own taxes because the forms are complicated and time-consuming to fill in, mistakes can be penalized with fines, and if you get your calculations wrong you could end up paying more tax than you really owe.

Common types of words people tend to repeat include:
-Fillers: Words like "um," "uh," "like," or "you know."
-Intensifiers: Words like "really," "very," or "so."
-Pronouns: Words like "I," "we," "they," or "it."
-Conjunctions: Words like "and," "but," or "because."
-Adjectives/adverbs: Words like "good," "bad," "interesting," or "quickly."

Incorrect subject-verb agreement can lead to confusion and hinder effective communication in writing. Readers might struggle to understand the intended meaning of a sentence, and it can create an impression of carelessness or lack of attention to detail on the part of the writer. Additionally, it can undermine the credibility of the text and make it appear less professional.
