A Reading Journey
Emma and Jake could not have been more different when it came to reading. Emma was a real bookworm (1) who spent every spare minute with her nose in a novel (2). Jake, on the other hand, was a non-reader who thought most books were a waste of time.
One day, their teacher announced a reading challenge. Emma was thrilled and immediately hit the books (3). Jake wasn’t excited at all. He took one look at the reading list and decided to judge the books by their covers (4), dismissing several of them as boring.
A few weeks later, Emma recommended a mystery novel to Jake. To her surprise, he gave it a chance. The book turned out to be a real page-turner (5), and he finished it in just two days. As the story became more complicated, Jake kept saying, “The plot thickens (6)!”
When the class met to discuss the novel, Jake shocked everyone with his thoughtful comments. He had even learned to read between the lines (7), noticing details and hidden meanings that many students had missed.
“Maybe I should take a leaf out of Emma’s book, (8)” he admitted. “Reading isn’t as boring as I thought.”
By the end of the semester, Jake had really turned over a new leaf (9). He wasn’t quite the bookworm Emma was, but he was no longer a non-reader. In fact, when the teacher announced the next reading challenge, Jake was the first to sign up.
“Well,” Emma laughed, “that’s one for the books (10).”
