Improving Sentence Structure
Empty subjects — words like “it” or “there”
Ex. It won’t take long to get there. There shouldn’t be any rain today.
Use it to refer to times and distances, describe situations.
Use there when you want to say that something exists.
Imperatives or interjections don’t need subjects.
Auxiliary verbs are verbs that reference another verb that is the action of a sentence.
Ex. I will call you later.
You can have a sentence without an auxiliary verb, but you can’t have a sentence with an auxiliary verb with no standard verb.
Using Commas Before And
Independent clauses have a subject and verb. When combining two independent clauses, add a comma before the conjunction. If there is no subject in the second clause, do not add a comma before the conjunction.
