Start with a strong hook:
* "This report/article/book..." - Directly introduces the subject matter.
* "The author argues..." - Introduces the main thesis or argument.
* "This research investigates..." - Highlights the topic and research question.
* "In this [type of work], the author explores..." - Provides context and scope.
Start with the main idea:
* "The main point of this [type of work] is..." - Clearly states the central theme.
* "This [type of work] examines..." - Focuses on the primary subject matter.
Start with the key takeaway:
* "The key findings/conclusions of this [type of work] are..." - Summarizes the most important aspects.
* "This [type of work] demonstrates..." - Emphasizes the main result or conclusion.
General guidelines:
* Keep it brief and concise. The first sentence should capture the essence of the summary.
* Be specific and informative. Avoid vague or general statements.
* Use clear and simple language. Avoid technical jargon unless it's necessary for understanding the topic.
* Consider your audience. Tailor the opening sentence to their knowledge and interest level.
Ultimately, the best way to start a summary is to choose an opening that is engaging, informative, and relevant to the material being summarized.
