论据的重要性

1.The Importance of Specific Details
Specific details are valuable in two key ways. 
First, details excite the reader’s interest. They make writing a pleasure to read, for we all enjoy learning particulars about people, places, and things. 
Second, details serve to explain a writer’s points. They give the evidence needed for us to see and understand general ideas.
 
2. The Importance of Adequate Details
First, one of the most common and most serious problems in students’ writing is inadequate development. You must provide enough specific details to fully support the point in a body paragraph of an essay. Without such additional support, your paragraph would be underdeveloped.
Second, students may try to disguise unsupported paragraphs through repetition and generalities. Do not fall into this “wordiness trap.” Be prepared to do the plain hard work needed to ensure that each paragraph has solid support.
