Sentences must be correct and constructed appropriately for the context

1. Construct sentences that conform to the rules of grammar and punctuation.

The value of a sentence is judged according to the rules of Standard Written English. This variety of English is not necessarily better or more efficient than the many other varieties of the language, but it is the standard used by the academic judges of writing. Think of the forms of sentences that you are used to reading in academic reading materials, but also think of the sentences that you have heard instructors use during lectures. As you write, listen in your mind to the voice of your favorite instructor as he or she lectures and pretend that instead of writing a timed essay, you are that instructor lecturing. By doing this, you will remember to use sentences that are formed by the standard rules of grammar and usage.

2. Construct sentences that are appropriate for the context.

Sentences may be constructed in a variety of ways. Learn the methods of constructing sentences. Sentences are made of parts that are often larger than words called phrases and clauses. Clauses are the basic sentence structure - subject and verb - and may be dependent or independent. Phrases are words or collections of words that act to modify or introduce parts of the sentence. Conjunctions are words or phrases that glue the parts of a sentence together. Construct sentences out of these parts. The resulting sentences may be short or long, questions or statements, complex or simple. Become familiar with these possibilities, and construct each sentence according to how it relates to the other sentences within the paragraph. Do not simply write down the first sentence that pops into your head, but think about the relation of the sentence with the sentences that come before or after it.
