With one of my students, I'm using the English breaking news, which reminded me of what I used to be.
Almost 2 years ago, I had a hard time reading articles on this web site, I couldn't really understand them without my dictionary.
Obviously, it was due to lack of my vocabulary.
Since then, because I have been building my vocabulary, I can smoothly understand them, which made me realize the importance of having a wide range of vocabulary.
