I don't know how long this text is, but if it is not too long,and you can post it here, I will try to help. When you summarize a piece of text, you should take one paragraph or section at a time, and write a sentence telling what is being said. You do not have to explain what is means, just tell what is being said in a shorter way. If a person can summarize something, it indicates that have understood what they have read. Teachers use this technique all the time.
