Question

how can we write a proper ,better precis?

Answer 1

Read and annotate the article or other text.

Reflect on the author's purpose.

Consider the kinds of evidence the author uses.

Restate the author's thesis in your own words.

Write a one or two sentence summary of each section or subdivision of the article.

Reread the article to compare it with your summary notes.

Begin writing, using your paraphrase of the thesis and your one or two sentence summary statements.

Review your précis to confirm that you have explained the main point of the article, identified the supporting evidence that the writer uses, and have used the same logical structure as the text.

Finally, check for clarity, coherence, and correctness.
