I finally have finished reading 50 phrasal verbs are easy. While I read this, I could prepare my Anki flash cards about unknown or unfamiliar words and learn valuable phrasal verbs of course.
As a few days go by, It can just be my mistake, I felt confident reading some English sentences which consist of phrasal verbs. I could guess verbs not only from this book but verbs that weren't inlcuded by guessing meaning of them. Somewhat, I could grasp nuances of those words or prepositions.
It's been a big improvement for me. The reason I chose this book is exactly what I've gained at the moment. I didn't expect I could get better to this extent.
Yes, it might be sort of arrogant.
In other words, I don't regret buying and reading this book.
I'm feeling grateful to Oliver and for his amazing English podcast.
