Here's why:
* "Having" is a participle - It's a verb form that functions as an adjective or part of a verb phrase. It typically describes a state or action that happened before the main verb of the sentence.
* "Having" requires a subject - A participle needs a subject to refer to. For example, "Having finished my homework, I went to bed." Here, "Having finished my homework" describes what the subject "I" did.
Instead of starting a sentence with "Having," try these alternatives:
* Use a regular verb: Instead of "Having gone to the store, I bought milk," say "I went to the store and bought milk."
* Use a prepositional phrase: Instead of "Having a lot of money, she bought a new car," say "With a lot of money, she bought a new car."
* Use an adverb: Instead of "Having worked hard, he passed the exam," say "He worked hard and passed the exam."
* Use a dependent clause: Instead of "Having been to Paris, I love French food," say "Because I have been to Paris, I love French food."
Exceptions:
* "Having said that..." This is a common phrase used to introduce a contrasting or qualifying statement.
* "Having been there..." This is a common phrase used to express experience or knowledge.
