Even though assignments come with length requirements, it is important to write as plainly and succinctly as possible. More is not necessarily better.
How can you write "plainly"?
Either use the one word form or omit the following phrases
for the purpose of-use to
in the near future-say soon
due to the fact that-write because
owing to the fact-use since
at this point in time-say now
with regard to-write about
Avoid there is, there are, and it is
There is, there are, and it is add unnecessary words to a sentence and take the emphasis away from the subject.
Compare
"There are many students at the seminary who believe that their flowery words are as good as Solomon's."
or
"Many students at the seminary believe that their flowery language is as good as Soloman's."
The word students is the subject of the sentence and, consequently, should be an important element, not buried in the middle of the sentence. The words "there are" don't add any information to the sentence.
Omit needless words
Longer is not better; it's just longer and often just verbose.
