8. By using the four types of sentences in your writing, you can
make your paragraphs more interesting.
Read the sample paragraph below.
My favorite type of fast food is pizza. I could eat pizza
morning, noon, or night. Pepperoni is my number one choice.
I also like double cheese on top. I wish I could order a pizza
right now.
Boring, right? Let’s see how we can use the four types of
sentences and make it more interesting to the reader.

9. What is your favorite type of fast food. My favorite is pizza
What is your favorite type of fast food? My favorite is pizza. I just love pepperoni and double cheese. Sometimes I think I could eat pizza morning, noon and night! All of this talk about pizza is making me hungry. Let’s order a pizza now.
This is more interesting, right? In this sample we used the four different types of sentences. They provided emotion, excitement, pizzazz to our paragraph.
Now you try. On your worksheet you will find a paragraph
consisting of nothing but declarative sentences. Rewrite your
paragraph so that you utilize the four types of sentences.

10. This summer I visited Six Flags Over Texas.
Several of my friends went with me. We had lots of fun.
There were lots of exciting rides. My favorite was the Titan
rollercoaster. It had lots of twists and turns at 90 miles per hour.
We rode it at least three times. I would like to visit Six Flags again.

11. Fragments
A SENTENCE FRAGMENT fails to be a sentence in the sense that it cannot stand by itself. It does not contain even one independent clause. There are several reasons why a group of words may seem to act like a sentence but not have the wherewithal to make it as a complete thought.

12. Examples
It may locate something in time and place with a prepositional phrase or a series of such phrases, but it's still lacking a proper subject-verb relationship within an independent clause:
In Japan, during the last war and just before the armistice. This sentence accomplishes a great deal in terms of placing the reader in time and place, but there is no subject, no verb.
It describes something, but there is no subject-verb relationship:
Working far into the night in an effort to salvage her little boat. This is a verbal phrase that wants to modify something, the real subject of the sentence (about to come up), probably the she who was working so hard.

13. Examples
It may have most of the makings of a sentence but still be missing an important part of a verb string:
Some of the students working in Professor Espinoza's laboratory last semester. Remember that an -ing verb form without an auxiliary form to accompany it can never be a verb.
It may even have a subject-verb relationship, but it has been subordinated to another idea by a dependent word and so cannot stand by itself:
Even though he had the better arguments and was by far the more powerful speaker. This sentence fragment has a subject, he, and two verbs, had and was, but it cannot stand by itself because of the dependent word (subordinating conjunction) even though. We need an independent clause to follow up this dependent clause: the more powerful speaker, he lost the case because he didn't understand the jury.
