To write a good summary, a person must read, understand and summarize the piece they have read in their own words. The purpose of writing a summary is to give the basic ideas about the piece.
The first step is to read the original piece without taking notes. This is necessary for understanding the piece that a person needs to summarize. A person should then reread the piece underlining the important points and taking down notes. He or she should then go through the original piece again focusing on the underlined points and the main ideas. The person can then write a summary of the piece in his or her own words.
