Grammar Post 5

I decided to do as Chelsi asked, and I researched "to be" verbs. This was the best information I found. It was found at: http://grammar.ccc.commnet.edu/grammar/to_be.htm#unnecessary

Unnecessary Uses of “To Be”:

Even a casual review of your writing can reveal uses of the verb “To be” that are unnecessary and that can be removed to good effect. In a way, the “To be” verb doesn't do much for you — it just sits there — and text that is too heavily sprinkled with “To be” verbs can feel sodden, static. This is especially true of “To be” verbs tucked into dependent clauses (particularly dependent clauses using a passive construction) and expletive constructions (“There is,” “There were,” “it is,” etc.). Note that the relative pronoun frequently disappears as well when we revise these sentences.

He wanted a medication that was prescribed by a physician.
She recognized the officer who was chasing the crook.
Anyone who is willing to work hard will succeed in this program.
It was Alberto who told the principal about the students' prank. (Notice that the “it was” brought special emphasis to “Alberto,” an emphasis that is somewhat lost by this change.)
A customer who is pleased is sure to return. A pleased customer is sure to return. (When we eliminate the “To be” and the relative pronoun, we will also have to reposition the predicate adjective to a pre-noun position.)

An expletive construction, along with its attendant “To be” verb, can often be eliminated to good effect. Simply omit the construction, find the real subject of the sentence, and allow it to do some real work with a real verb.

There is one explanation for this story's ending in Faulkner's diary. (Change to . . . .) Faulkner's diary gives us one explanation for this story's ending.
On the other hand, expletive constructions do give us an interesting means of setting out or organizing the work of a subsequent paragraph:
