In other words, avoid using words like "I," "my," and "you." Because you are the author of the paper, readers will assume opinions offered in the paper are yours; there's no need to emphasize this by using first person. For example--
NOT: I believe the author's use of detail helps readers understand life in the 1800s.
BUT: The author's use of detail helps readers understand life in the 1800s.
Your paper will be the most clear and easy to read if you always state who/what is doing the action at the beginning of your sentences. Take a look:
NOT: This book was written for the general reader. (Who wrote the book?)
NOT: This book was written for the general reader by Bob Laureate. (Why hold out until the end?)
BUT: Bob Laureate wrote this book for the general reader.
Many times if you start a sentence with words like "this" and "that," it is unclear what these words refer to. It's better to be specific, even if it may seem like you're repeating yourself.
NOT: The author included many first-hand accounts of slavery in the article. This helps readers empathize with the slaves.
BUT: The author included many first-hand accounts of slavery in the article. These song lyrics and testimonials help readers empathize with the slaves.
