Sometimes you may feel that it is important to include a rather lengthy section of the original text in your paper. If the section is 40+ words long, the quotation should be formatted as a block quotation; please see the APA style rules on formatting a block quotation for more information.
Sample block quotation

Tip: Writers usually use a clarifying sentence with a colon to introduce a block quotation.
