Answer:
A good rule to introducing ideas without sounding repetitive is to think what you're trying to add to your writing.
If you're beginning to illustrate, try "For example...", "Such as...", "For instance...", "To clarify...", "Respectively...".
Sometimes, if you're emphasizing your point, you can say "As aforementioned...".
If you're talking about a cause and effect, some sentence starters are "Because...", "So...", "Therefore...", "Thus...", "Consequently...", or "Hence...".
Happy Studying!
