Proofreading Your Paper

Proofreading Your Work

            It is always difficult to find errors in one’s own work.  The words and sentences appear correct on rereading, because if the writer had known better, he would not have made the errors in the first place!  Yet, a careful out loud rereading of a paper before it is turned in helps considerably.

Run-on Sentences and Sentence Fragments

·        Check each sentence to make sure it has a subject,  verb, and complete thought.

·        Have you run two sentences together incorrectly with neither period, conjunction nor semicolon separating them?

Punctuation

·        Have you ended every sentence with a period, question mark, or exclamation point?

·        Are your thoughts within sentences broken up correctly by commas for easier understanding?

·        Have you broken up series by commas?

·        Have you used a period after abbreviations?

·        If you are in doubt about the proper punctuation of a sentence, have you asked about it or looked it up in your grammar book?

Quotation Marks

·        Did you remember to place exact quotes within quotation marks?

·        Did you place all periods and commas inside the quotation marks while placing semicolons and colons outside them?

Verb-Subject Agreement

·        Check every subject and verb to make sure that if you have used a singular subject, you have also used a singular verb.

·        Similarly, a plural subject needs a plural verb.

Sentence Length

·        Have you varied the length of sentences in each paragraph?

·        If your sentence are too long, brake them into shorter units.

·        Sentences which are very short tend to produce a jerky style of writing.

·        Does each sentence follow clearly and logically from the one before it?  Have you used some type of transitional device between each sentence.?

Apostrophes

·        Have you used them correctly to indicate possession?  If you are unsure, check a grammar book.

Tenses

·        Have you incorrectly jumped about in different tenses?

·        Have you used the correct form of the verb to express the tense you want?

Capitalization

·        Have you capitalized names of persons, cities, countries, streets, and titles?

·        Have you capitalized a quotation according to the original and needs of you sentence?

Spelling

·        Check words you have any doubt about.

·        If you are unsure of the spelling of a certain word, look it up. 

·        Be especially careful of the words listed as spelling nightmares;  also ei and ie words, words which add -ing and -ed and words with one or more sets of double letters.

Paragraphing

·        Does each paragraph have a topic sentence which states the main idea?

·        Have you used examples and vivid specific details to describe your topic?

·        Have you used explanatory sentences to give your opinion or judgment on the topic?

·        Have you included sentences which pertain only to the idea?

·        Are transitions used between sentences and paragraphs?

·        Is there a concluding sentence/paragraph?

Omissions

·        Have you left out any words in your sentences?
