Recently, I came across a seemingly good method, but the method itself is not the most important thing.

- Read the first paragraph and write a sentence summarizing the main idea or extracting the key points in the blank.
- Read the second paragraph and do the same.
- There are some changes in the third paragraph, write two sentences, the first one summarizing the previous paragraph, and the second one summarizing the third paragraph.
- Then, continue in the same way, writing two sentences for each subsequent paragraph.
However, it is not very user-friendly for e-books, so I recommend printing it out for reading.
