1. A good summary should include the main points or key ideas of the original text. It should be concise, capturing the essential information without unnecessary details. Additionally, a good summary should be objective and unbiased, avoiding personal opinions or interpretations. It should also maintain the original context and tone of the text.
2. One thing that a summary should not include is additional information or new ideas that were not explicitly stated in the original text. This is because a summary aims to condense the main points of the text, so including new information would distort the accuracy and purpose of the summary.
