Someone who has really good vocabulary to me write an amazing introduction

Use transitions and a hook to make your paragraph strong. like however, although, in fact, to begin, moreover, and etc. search up, "transitions" and you'll find good use of vocabulary words. A hook is try to make your introduction paragraph with a statement, proof, and support to catch your readers eyes. Like use some journalism skills like a lead and a kicker, those will help you a ton. Opinion Lead, Rhetoric, or even a persuasive lead helps make NOT just your paragraph stand strong but also helps the rest of your article or essay stand alone. 
Hope this helps :)
